Herbst 1967 - The Fisher Handbook - Teil 3 - die Geräte

Auch "The Fisher" hat es gemerkt, die modernen Hifi-Stereo Produkte sind erklärungsbedürftig und der Markt ist noch lange nicht reif, von allein zu kaufen. Die Interessenten, die überhaupt auf diesen Zug aufgesprungen waren oder gerade am Erkunden waren, brauchten Hilfe.

Diese schwarz-weiß Broschüre im amerikanischen B4 Format hat schon richtiges Geld gekostet, doch der gesamte amerikanische Markt stand offen und das waren nicht unerhebliche Möglichkeiten. Fisher hatte sich den bisherigen Hif-Markt mit nur ganz wenigen Mitbewerbern geteilt, die dort im oberen Bereich überhaupt etwas Vernünftiges anbieten konnten.
.

Dieser 74seitige Prospekt, also das "The Fisher handbook", ist schon sehr ausführlich. Damit es überhaupt lesbar ist, hatte ich das in drei Teile zerlegt. Hier ist der Teil 3 mit den Fisher Geräten Frühjahr 1968.

Herbst 1967 - The Stereo Receiver

EVERYTHING YOU NEED ON ONE, BEAUTIFULLY INTEGRATED CHASSIS
Simply Add Two Speakers of Your Choice

Some people believe only a technically inclined individual can properly select a high-quality, precision-engineered high fidelity system. Nothing could be further from the truth.

Today anyone who can read and hear can quickly select an outstanding stereo high fidelity system. And installing a component hi-fi system is a great deal easier nowadays than putting up a TV antenna.

This simplification was achieved by combining all the many specialized components one required for stereo onto one, completely integrated chassis. This instrument is known as a Receiver, and the most popular components in the high fidelity industry are Fisher Receivers. With the purchase of a Receiver, all one needs to do is add a pair of speaker systems. Speaker cables can be connected to a Receiver in seconds.

All Fisher Receivers are matched to all Fisher Speaker Systems. The wide selection of Fisher Receivers and high-compliance Fisher Speaker Systems make it possible for one to 'personalize' a stereo system to any taste.
Fisher Receivers are available in moderately-priced, deluxe and luxury class models. Their circuitry is of tube, all-transistor or Integrated Circuit design, and are therefore available to meet the taste and budget of any music lover. Each model, regardless of cost, is designed to the highest standards in performance: they will not sound strikingly different. But they differ greatly in all other aspects, such as flexibility of control, power handling capacity, conveniences, number of input and output connections, physical size, engineering circuitry, and external appearance.

Its easy-to-use flexible controls and switches are complemented by two separate modes of tuning: Tune-O-Matic® push-button selection on five separate FM dials, and the familiar flywheel control for conventional tuning along the extra-wide dial glass in the upper insert panel.

After pretuning each push-button to one of your favorite stations, the Tune-O-Matic® circuit permits you to select any of five FM stations at the press of a button, with perfect center-of-channel accuracy. Whatever your choice, Automatic Frequency Control (AFC) provides perfect center-of-channel tuning- electronically locks in the desired FM station. This is electronic diode tuning-totally different from and infinitely superior to mechanical push-button tuning.

The FM tuner front end has the high sensitivity, selectivity and overload rejection one would expect from advanced FET solid-state circuitry. By using Integrated Circuits (IC's) in the IF amplifier, all possibility of human error is eliminated in these circuits, thus assuring outstanding reliability. These IC's are equivalent to the use of four separate IF stages and three limiters. As a result, weak and distant stations you might never enjoy are now within easy reach. Even if you reside near a powerful FM transmitter, the 250-T's high overload capacity enables it to handle strong signals from that transmitter to assure optimum rejection of spurious response.

Stereo Beacon*, an exclusive Fisher achievement, automatically signals the presence of stereo and automatically switches to the stereo mode. The d'Arsonval tuning meter permits one to obtain perfect center of channel tuning with pinpoint precision. This signal-strength meter, arranged on a scale from 1 through 5, indicates the single best point for lowest distortion and maximum stereo separation of the desired signal.

The preamplifier section of the Fisher 250-T is a worthy complement to the tuner. Dual-concentric bass and treble controls, using Baxandall feedback circuits, permit the listener to adjust left and right channel independently to suit room acoustics or to compensate for tonal imbalances in program material. A loudness contour switch restores the natural tonal balance of the high and low ends of the audible spectrum at lowest volume settings. A muting switch eliminates FM interstation noise and hiss.

The six-position Program selector permits one to tape record any program source and know that the performance will be a superb reproduction of the original material.

Four switches, to modify and control the audible sound, attest to the versatility of the instrument. Loudness Contour restores the tonal balance of lower bass and upper treble. These normally tend to thin out at lower volume settings. The Muting Switch removes hiss, static and other interstation noise on FM as one tunes in along the dial. The High Filter switch removes annoying high-frequency noise from any program source (usually scratchy records). The Main/Remote Speaker Switch is generally used in conjunction with the headphone jack. It is designed for those who prefer to listen to stereo in complete privacy without disturbing others in the room, or who prefer a choice of listening to music in the main installation or remote area-the den and living room, or bedroom, for example. With 90 watts of power to draw on, the Fisher 500-T can drive the most inefficient speaker systems to full room volume.

Herbst 1967 - The Speaker System

HIGH-EFFICIENCY, HIGH-COMPLIANCE SOUND REPRODUCERS
An electronic device, such as an Amplifier or Tuner, merely transmits an electrical signal that is scientifically measurable, but not yet audible. The speaker must process and convert the signal to audible sound so that your ears may hear precisely what is being broadcast, taped or recorded. That is why a high-quality stereo system is only as good as its speaker system, and why it is best to select the finest loudspeaker system possible, within budget and physical space limitations.

Of all the standards used in rating speaker performance, the two most useful criteria are Efficiency and Compliance. Efficiency is a unit of measurement relating to the amount of electrical power required to produce a given amount of acoustic power. Compliance is the degree of freedom required by a speaker cone in order to properly reproduce the audible range. All Fisher speaker systems, regardless of size or cost, have been designed with both exceptionally high efficiency and high compliance. As a result, all Fisher speaker systems have a natural-sounding resonance-free character.

The Fisher XP-7™

Free-Piston 3-Way Speaker System
The Fisher XP-7 is a three-way speaker system with four loudspeakers: a massively-built 12-inch bass driver, two identical, linear-matched 5-inch mid-range speakers, and a 1 1/2-inch wide-dispersion treble speaker with exclusive soft-cloth, dome-shaped construction. In a comparatively short time since its introduction, the XP-7 has been awarded more top-level ratings from important national consumer magazines than any system of comparable size and cost.

Each of the two mid-range drivers are housed in separate, tightly sealed compartments to prevent interaction among bass and mid-range. This 'speaker-within-a-speaker' design is responsible for a full-bodied, in-phase sound.

The bass speaker has a 5 1/2-pound magnet structure and a voice coil diameter of 1 1/2 inches, all tending to eliminate distortion that might ordinarily occur at high volume levels, or in the reproduction of bass tones of 30 to 40 Hz. The outside surround is impregnated with a non-drying butyl liquid, thus providing exceptional compliancy to the cone, and enabling the bass to reproduce frequencies of 30 Hz without doubling or overshoot.

A low-loss 12 db-per-octave inductive-capacitive crossover network controls the frequency separation at 300 and 2,500 Hz.
Few speaker systems, at any price, even compare to the magnificence of the Fisher XP-7. Its flat, smooth and neutral character reflects the finest in speaker engineering.

Cabinet: Oiled Walnut

The Fisher XP-66™

Free-Piston 3-Way Speaker System
A three-way speaker system of bookshelf size has been designed by Fisher Laboratories for those who prefer high quality at moderate cost. Its smooth, balanced sound can be attributed to the use of premium-grade transducers and a laboratory-matched crossover network.

The 12-inch high-compliance free-piston bass speaker handles frequencies down to 30 Hz without distortion or doubling. Transient response of the lower frequencies is assured by the use of a 5-pound magnet structure and butyl-impregnated half-roll surround.

The mid-range portion of the audio spectrum is reproduced by a six-inch speaker which is sealed off from other elements of the system by a sub-enclosure. This prevents acoustic interaction between mid-range and woofer.

Extremely high frequencies are less likely to radiate uniformly in all directions. For this reason, Fisher laboratories have designed a wide-dispersion cone-type treble speaker. Because of its low-mass cone, the speaker achieves excellent transient response up to the limits of audibility. It is constructed of a special fibrous material, and is highly damped to eliminate annoying distortion caused by cone resonance and breakup to provide outstandingly smooth reproduction of the "highs."

Frequency separation at 400 and 1,000 Hz is controlled by a low loss 12 db per-octave inductive-capac-itive crossover network. The tightly-sealed enclosure is constructed from heavily-braced sheets of dense, non-resonant material with bonded walnut veneers.
Frequency Response: 30 to 19,000 Hz
Recommended Amplifier Power: 10 to 60 watts - Impedance: 8 ohms

Free-Piston 4-Way Speaker System
The significant difference in this loudspeaker system is one which becomes instantly apparent when you hear it. For the first time, a system has been designed to split the full-frequency range into four sections rather than the customary three. The bass speaker, with its compliant cone and heavy magnet structure, concentrates solely on frequencies from 28 to 300 Hz; the 6-inch lower mid-range reproduces frequencies of 300 to 1,000 Hz; the 5-inch upper mid-range from 1,000 to 2,500 Hz; and the 1 1/2-inch soft dome, wide-dispersion treble speaker reproduces frequencies from 2,500 Hz to beyond audibility.

This four-way crossover network removes all likelihood of distortion or tonal imbalance in the sound reproduction of the original program. Audible response is amazingly uniform and natural-crystal clear in the highs, smooth and transparent in the mid-frequencies, clean, tight and solid in the lows. Each speaker in the system is isolated, to avoid interaction between bass and mid-range units. The three-position treble balance control, located at the rear of the speaker system, allows you to adapt the texture of the upper frequencies to the acoustics of the room.
The elaborate all-electrical crossover design has precisely wound coils and capacitors to filter out those frequencies that are above or below a particular driver's operational limit without losses.
Frequency Response: 28 to 22,000 Hz
Recommended Amplifier Power: 10 to 60 watts - Impedance: 8 ohms
Dimensions: 14" wide x 24" high x 12" deep - Weight: 60 pounds
Cabinet: Oiled Walnut

The Fisher XP-10™

Consolette 3-Way Speaker System
In its smoothness, transient response and overall musical quality, the Fisher XP-10 borders on absolute perfection. The bass speaker is a mammoth 15-inch transducer with a 6-pound magnet structure and voice coil diameter of 2 inches. Even the lowest bass tones are flawlessly reproduced, regardless of amplitude. The mid-range speaker is eight inches in diameter - larger than the bass speaker in some economy models. As a result of its extraordinary size, this speaker can handle the entire range of mid-frequencies from 200 to 2,500 Hz with spectacular ease. To avoid acoustic interaction, the mid-range unit is housed in a separate, air-tight sub-enclosure heavily padded with Acoustiglas.
The high frequencies are reproduced by a peripherally driven, hemispherical treble speaker that has a soft-cloth dome bonded directly to the light copper voice coil.
Frequency Response: 28 to 20,000 Hz
Recommended Amplifier Power: 10 to 60 Watts - Impedance: 8 ohms

The Fisher XP-12™

Console Three-Way Speaker System
The remarkable new Fisher XP-12 sets an entirely new standard of excellence in performance and quality. It incorporates many of the latest engineering advancements pioneered by Fisher, to provide sound reproduction that must be heard to be believed.

Three acoustically-matched transducers have been incorporated in a system that features only the finest components and materials.
The 12-inch bass speaker has a six-pound magnet structure. Its extremely compliant surround is combined with a specially prepared cone material to afford wide excursion and smooth, resonance-free response. The system has a low bass-to-mid-range crossover of 400 Hz, thus permitting the bass speaker to operate at peak efficiency in the lower three octaves of the audible spectrum.

The eight-inch mid-range speaker has been specially designed for this consolette speaker system. It reproduces frequencies between 400 and 2500 Hz with flawless fidelity.

The treble speaker is a wide-dispersion 1 1/2" hemispherical soft-dome type*, providing pure, uncolored sound to beyond the limits of audibility.

Each of these elements, including low-loss inductive-capacitive crossovers at 400 and 2500 Hz, have been tailored to the physical size of the system. Every nuance of the musical program-from the lowest bass tone to the highest tones of the flute - are reproduced with astonishing purity and presence. All in all, the new Fisher XP-12 is worthy of the most discriminating music devotee.
Frequency Response: 30 to 20,000 Hz
Recommended Amplifier Power: 10 to 50 watts - Impedance: 8 ohms
Dimensions: 24" high, 22" wide, 13" deep - Weight: 60 pounds
Cabinet: Oiled walnut

The Fisher XP-15B™

Consolette Three-Way Speaker System
Every hallmark of fine Fisher engineering and design-magnificent styling, precise transient response, exceptional tight and solid lows that will not muddy even at 28 Hz - have been incorporated in an instrument of exact proportion.

The new Fisher XP-15B is a speaker system that extends beyond the bounds of mere professionalism. It is truly a model of perfection in every detail. The fifteen-inch bass speaker features a unique half-roll surround of extreme compliancy as well as a massive 12-pound magnet structure and 21/£-inch diameter voice coil. Such oversized and conservatively rated materials assure the speaker's capacity to perform perfectly within its assigned frequencies of 28 to 400 Hz.

The eight-inch mid-range speaker-a size considerably larger than bass drivers in other units-reproduces the frequencies between 400 and 2500 Hz. The 1 1/2-inch hemispherical treble speaker utilizes a soft-dome diaphragm* that has excellent dispersion characteristics. Transient response is also unsurpassed because of the unusually high flux density of the tweeter magnet structure and the low-moving mass of the tweeter diaphragm.

A tweeter level control has been incorporated at the rear of the instrument. This calibrated three-step type permits one to boost the high frequencies when necessary, or reduce the emphasis on the treble tones to suit the acoustical environment of the room. The new Fisher is of handsome appearance and will blend perfectly with any home decor.
Frequency Response: 28 to 20,000 Hz
Recommended Amplifier Power: 10 to 60 watts - Impedance: 8 ohms
Dimensions: 27" X 27" X 14" deep - Weight: 80 pounds
Cabinet: Oiled walnut

The Fisher XP-18™

Consolette Four-Way Speaker System
When the performance goals were established for the design and development of the Fisher XP-18, foremost among them was the aim to produce a speaker system totally free of coloration. Such a unit was to be of 'transparent' quality, imposing nothing of itself between the signal source and the listener. The Fisher XP-18 has met these goals to a degree even beyond our highest expectations.

Heart of the speaker complement is a massive 18-inch bass woofer-the largest high quality loudspeaker ever designed for home use. It is capable of handling frequencies down to 14 Hz (2 cycles below the lowest organ tone in the world) and has overwhelming power handling capacity. Its 2-inch voice coil operates in a 12%-pound magnet structure, providing critical magnetic damping that produces an amazingly solid, non-resonant bass, covering the range from 14 Hz to 150 Hz.

An 8-inch lower mid-range unit reproduces the frequencies between 150 and 1500 Hz. Like the bass speaker, the lower mid-range unit is sealed in its own sub-enclosure to prevent acoustic interaction with other speakers in the system. Its upper mid-range unit is a smaller, 5%-inch free-piston speaker in a vented sub-enclosure. The upper mid-range speaker reproduces frequencies from 1500 to 3000 Hz.

The upper limits of the audible spectrum are handled by two linearly matched 2-inch treble speakers.
Frequency Response: 30 to 22,000 Hz
Recommended Amplifier Power: 10 to 60 Watts - Impedance: 8 ohms
Dimensions: 29" high, 30" wide, 16" deep - fTeight: 105 pounds

Herbst 1967 - The Tuner

HIGH SENSITIVITY FM and AM-FM STEREO TUNERS
The development and design of a fine tuner is the most complex of all projects one can assign an audio engineering staff. It must have the capability of locating, sensing, and converting signals that are normally measured in a few millionths of one volt into enjoyable and useful dimensions measured in many times their original power.

The advent of FM-Stereo multiplex programs and the solid state circuitry now available have accelerated both the complexity and opportunity for brilliant design.

Since the dawn of the high fidelity era, Fisher tuners have been recognized as the finest in the world. They can be found in hundreds of American and foreign broadcast stations, including the world-renowned Royal Telecommunications FM Network of Sweden. The selection of the Fisher Tuner is based on the consistent, reliable and unparalleled performance it offers, especially in its Sensitivity and Selectivity. The first is the measure of a tuner's capacity to sense the presence and enlarge to usable form weak signals from the broadcast station. This capacity is measured in microvolts (millionths of a volt). The lower the figure, the finer the tuner. Selectivity represents the capacity of the tuner to receive the station it has selected perfectly, without interference from other stations. Selectivity is measured in decibels. The higher the number, the better the tuner.

The Fisher R-200-B is the world's first high fidelity tuner that offers facilities for the reception of regular AM broadcasts, shortwave stations, and weather and navigation longwave, in addition to matchless FM reception. It offers the music lover direct access to cultural centers throughout the world.

The crowning gem of all Fisher tuners is the Fisher TM-1000. There is no other like it in all the world, for it incorporates seven exclusive circuit features that will set the standard of performance for years to come.

The Fisher R-200-B™

All-Transistor FM-Stereo, AM, Short Wave Tuner
Wherever you go, wherever you are, the Fisher R-200-B will keep you in touch with the news and music of the world. A newscast from London, a concert from Paris, a weather report from Singapore- all the cities of the globe can be tuned in with miraculous presence with this remarkable FM-Stereo, AM and Short Wave tuner.

The Fisher R-200-B is the ideal tuner for those who seek world-wide entertainment programs. Its sensitivity and selectivity approach the theoretical limits of tuner capability.

The instrument has five frequency bands for the reception of FM-Stereo, standard AM, weather and navigation, 41-meter to 19-meter short wave, and a 49-meter short wave bandspread scale. Nineteen tuned fixed circuits provide maximum efficiency and stability. Even under adverse conditions, it will operate magnificently, regardless of geographic location.
The high-sensitivity FM section features a new version of the Fisher Golden Synchrode front end for high overload rejection. Another feature of the FM section is Stereo Beacon, a Fisher trademark and patent, that signifies that the R-200-B has the convenience feature of automatically switching to the stereo mode, signaling the presence of a stereo broadcast, and automatically switching back to mono again-according to the type of program being received.

Highest selectivity is maintained by using a tuned AM-RF stage and a three-gang AM tuning capacitor. The Automatic Gain Control (AGC) smooths out variations in signal strength, and minimizes slow or fast fading, particularly important on short wave reception.

The large AM ferrite antenna has a static shield to make it virtually insensitive to man-made, electrical interference. An external wire antenna is included for long distance reception of all bands, especially short wave.

The Fisher R-200-B has facilities for optimum performance both in the United States and abroad. A multi-tap transformer permits operation of the tuner on 50 to 60 Hz power lines from 100 to 135 volts, and 200 to 250 volts.
Controls include Band Selector (FM, MW, LW, SW, 49M); AM Bandwidth (Sharp, Normal, Wide); FM Stereo Mode (Mono, Auto, Stereo); FM Muting; Power (AC Off, On) ; Tuning.
Dimensions: 15" wide, 41" high, 14" deep (maximum depth from control knobs to rear antenna in extended position). - Weight: 18 pounds.
Cabinet: Walnut, Model 50-UW, optional at additional cost.

The Fisher TFM-1000™

Laboratory-Standard, All-Transistor FM-Stereo Tuner
The TFM-1000 is the first FM-Stereo tuner with absolutely perfect facilities for receiving FM broadcasts. It is in every way the ultimate tuner. It has no traceable distortion. It will not overload. It represents a giant stride beyond all previous conceptions as to what an FM tuner should be, and what it must be able to do.

The Fisher TFM-1000 has seven exclusive all-transistor circuits - more engineering 'firsts' than have ever before been incorporated in a single high fidelity component. These unique features are largely responsible for the unprecedented degree of excellence at every level-performance, flexibility, ease of operation, reliability, and elegant appearance.
The SUPER SYNCHRODE front-end uses silicon field effect transistors (FET's) for suppression of spurious response and high overload capability. The double-shielded front-end has two RF stages, a four-gang variable capacitor, and six tuned circuits. This front-end module is one of the most significant engineering achievements in the instrument. It attains the highest known overload capability, selectivity, and rejection of spurious response to a degree in excess of 100 db! To bring the sensitivity of the Fisher TFM-1000 to its theoretical limit, a total of five IF stages and four limiters have been incorporated. A unique overload suppressor circuit automatically holds the signal strength of the FM signal within a range that can be easily handled. It is created by the combined action of an automatic RF attenuator with that of a wide-band attenuator in the IF strip. The result is to give the TFM-1000 a dynamic range superior to that of any FM tuner ever produced.

The most revolutionary feature of this instrument is the counter detector demodulator with symmetrical hard limiters. This exclusive limiter and detector circuit was, from its inception, developed to the most exacting specifications. It completely eliminates distortion and achieves the remarkably low capture ratio, never before attained, of 0.6db. It has no tuned circuits and is therefore not subject to drift. As a result its unparalleled performance will be maintained indefinitely.

The four-diode coincidence circuit used in the time-division multiplex section eliminates triggering caused by spurious signals. Only the true signal can trip the mono-stereo switch. Separation reaches the limits of perfection. At 1kHz, it is more than 40db; at 15kHz, it is better than 30db.

The push-button-operated clear signal indicator shows the relative purity of received FM signals. It is an invaluable tool for orienting rotatable antennas.

A new power amplifier circuit has been incorporated in the tuner. The balanced transformer-driven outputs provide sufficient audio power for high quality, low-impedance headphones. Either low or high-impedance headphones can be plugged into the front panel for use with a separate volume control. Separate transformer windings provide additional balanced 600-ohm outputs for professional use.

By any standard, there is no finer tuner in all the world. The Fisher TFM-1000 has been designed exclusively for those discriminating music lovers who demand absolute perfection.
Dimensions: 16" wide, 5" high, 12" deep (maximum depth from control knobs to rear fuse post). - Weight: 18 pounds.
Cabinet: Walnut, Model 100-UW, optional at additional cost.

Herbst 1967 - The Amplifier

HIGH RESERVE POWER and FLEXIBLE AUDIO CONTROLS ON SEPARATE OR INTEGRATED CHASSIS

The control-amplifier is the heart of a high quality stereo system. Its twofold function is to amplify the signal to the desired audible level, and to control the brightness and body of the sound, with the separate bass and treble tone controls. The loudness control maintains the desired relationship between bass and treble, even at low volume settings where ordinarily extreme bass and treble tone tends to thin out and disappear. (Human hearing is more uniformly efficient at higher volume levels).

At the outset, a fine high fidelity system may comprise a control amplifier, a pair of speakers, and a turntable or record changer-a combination obtainable at surprisingly modest cost. One can, at a later date, add a high-quality tuner, or tape recorder, or both, and thus enjoy unlimited freedom in selecting original program material.

In general, it is wiser to build gradually, with components of higher quality, than quickly with components of lesser quality. Good equipment can be expected to last twenty-five years, making the difference in cost between ordinary equipment and superb equipment relatively small.

Fisher control-amplifiers cover a wide range
of reserve power and control flexibility. All Fisher amplifiers more than meet the requirements of the average home, with sufficient reserve for the addition of speakers in other parts of the home.
.

The Fisher TX-1000™

For those who seek an exemplary instrument in audio power and control, Fisher presents the TX-1000 - a 120-watt control-amplifier with the most sophisticated and reliable circuitry ever conceived for use in a high fidelity component. It has more power, more audio control and more pure performance than any other component at any cost, and is winning the accolades of all audio connoisseurs.

It features push button controls for speaker selection, filters and loudness contour. Its plug-in jacks for tape and phones, located on the lower insert of a magnificent gold-plated front panel, add an extra measure of convenience. With the headphone jack, one can enjoy the musical program in privacy, without disturbing others in the room.

The six-position program selector permits a choice of microphone, tape, phono, tuner, and includes inputs for reception of the audio portion of two auxiliary program sources, (i.e. telecast, movie, etc.) The separate Tape Monitor selector features Left and Right positions to facilitate playback of each of the four tracks of a monophonic tape through both loudspeakers simultaneously. Its Direct Tape Monitor feature permits one to instantly check the quality of the material being taped and make adjustments without changing cable connections.

The center channel output is an added feature to enable one to drive a third or remote speaker system. With 120 watts of music power (IHF), the new Fisher TX-1000 has more than adequate reserve to drive speaker systems in other rooms of the home.

Not only is this instrument the ideal for the most critical audiophile, but is definitely the most logical choice for the newcomer who can afford the luxury of the finest in enjoyment of records and tape.
This powerful and flexible instrument is the most reliable component in the high fidelity industry. Its all-silicon transistor circuitry is designed to operate smoothly under all operating conditions. This assurance of superb, trouble-free performance more than compensates for its higher cost, for it promises virtually unlimited years of service.
Dimensions: 15" wide, 4" high, 12" deep (maximum depth from control knobs to rear heat sink). - Weight: 24 pounds.
Cabinet: Walnut, Model 50-UW, optional at additional cost.

The Fisher TX-100™

65-Watt All-Transistor Stereo Control Amplifier
The Fisher TX-100 is the first high-quality, all-transistor control amplifier available at a budget price. This reliable instrument provides more pure undistorted watts per dollar than any other instrument on the market today. Its total output-65 watts of music power (IHF) -is more than enough to drive additional speaker systems in other rooms of the home. Its flexibility of controls rivals many professional-quality units.
These include a four-position Program Selector (Tape Head, Phono, Tuner, Aux) and a two-position Mode selector (Mono/Stereo), as well as matched volume, balance, bass, and treble controls.

The front-panel headphone jack, coupled with the use of a main/remote speaker switch, permits one to enjoy music in other rooms of the home, or in private, without disturbing others in the same room. The Loudness Contour switch automatically increases volume of the very low bass andtreble tones to an audible level, and recreates the proper tonal balance of treble and bass. The exclusive Fisher Direct Tape Monitor permits one to monitor a tape recording with the use of all controls and switches, without changing cable connections.
Rear panel convenience facilities include Tape Head, Phono, Tuner and Aux inputs. The Phono inputs have a slide switch for selecting low or high level cartridges.

All in all, the Fisher TX-100 is a prize performer that compares favorably to the more expensive instruments of professional calibre.
Dimensions: 15" wide, 4" high, 12" deep (maximum depth from control knobs to fuse post). Weight: 17 pounds.
Cabinet: Walnut, Model 50-UW, optional at additional cost.

The Fisher X-100-A™

40-Watt Stereo Master™ Control Amplifier

Herbst 1967 - Read What High Fidelity Magazines
Say About the Fisher X-100-A

SINCE 1937, Fisher have pioneered many ideas in the audio field, and today they are probably the largest makers of hi-fi equipment in the world. One of the secrets of Fisher success is the high standard of engineering coupled with a rigorous quality control-plus a great regard for the actual styling which, I believe, is designed by Avery Fisher himself.

The X-100-A amplifier gives some 20 W per channel, and by American standards it would be rated as a fairly small job. Nevertheless, it lacks few of the really worthwhile features of the larger, more expensive amplifiers and-let's face it-a total of 40 W is plenty for most of us (and that goes for the neighbours, too!). It is a valve amplifier-but don't let that discourage you, because the performance is at least as good as that of most transistor amplifiers available at present. Styling is typical of the Fisher range, with its distinctive die-cast golden panel and elegant matching knobs.

The Fisher HP-50™
Stereo Headphones

The spring steel headband is vinyl-covered and fully adjustable. A single, 61/£-foot cable with 3-contact plug provides the necessary connections.
All Fisher Receivers and Amplifiers have headphone jacks on the front panel, and the Fisher HP-50 is a logical audio accessory for every Fisher component.

Fisher stereo headphones are the ideal complement to private listening enjoyment. Not only do they faithfully provide all the living acoustic presence of the original program material, but offer a degree of comfort and convenience heretofore unknown in headphone design. The cups are constructed of full foam-cushioned, high-impact Cyclolac plastic for maximum comfort.

The Fisher WS-2™

WIDE-SURROUND® Speaker System
Many Fisher Receivers and Fisher Amplifiers have facilities on the rear panel for wiring remote speakers in addition to the main speaker. These terminals can be used to hook up the WS-2 speaker systems.
Each unit incorporates an 8-inch by 3-inch oval permanent magnet speaker. Frequency response is 250 to 15,000 Hz, with sharp cutoff at 250 Hz. Available in Walnut. Dimensions: 10" wide, 4" high, 4" deep. Weight: 4pounds.

The new Fisher WS-2 eliminates the 'point' source of sound and thus creates the illusion that any seat in the room is front row center. This is accomplished by exploiting a phenomenon known as the Haas effect. In this, the direction of identical sound reaching the listener from two sources is determined by the one closest to the listener. Furthermore, the sound will always appear to be emanating from the nearer source even though the more distant source is louder.

The Fisher K-10™

Dynamic Spacexpander®
One control regulates the desired degree of reverberation.
Within recent years, there has been a renewed popularity in the Fisher K-10. Its special reverberation effects make it ideal as an adjunct for the guitarist who, in addition to tremolo and vibrato, seeks to add reverberation to his guitar amplifier. In addition, the Dynamic Spacexpander® is used in many commercial applications where new and exciting dimensions to sound prove desirable.

The Fisher K-10 Dynamic Spacexpander® electronically recreates the reverberation of the concert hall by artificially reflecting sound so that it reaches a listener's ear a fraction of a second later than it normally would. This reflection, or delay, is identical to the way one would hear a concert in an auditorium, and adds a new dimension to listening pleasure, even in the smallest of rooms. The K-10 works equally well on records, tape and broadcasts.

Why Fisher Owners Keep On Being Fisher Owners

.

  1. Engineering Without Equal
    One need only evaluate the products and inventions bearing the Fisher name to realize the calibre and thoroughness of Fisher engineering. One recent example is the Fisher 700-T, the world's finest transistorized FM receiver. Fisher engineering leadership has prevailed since the founding of our business, in 1937.
  2. Test and Inspection
    Every single part in a Fisher instrument, whether you can see it or not, has been selected as though it were the most important part. It is subjected to constant scrutiny and test-from the moment it arrives at our Receiving Department, to the moment the complete instrument is placed in a dust-free, moisture-free plastic bag and sealed in its container for shipment to our customers.
  3. Automated Electronic Test
    Every electronic test and alignment procedure to which a Fisher instrument is subjected is handled by fully automated instruments designed and built in our own laboratories by Fisher engineers. Every single piece of equipment receives the same complete and thorough tests. In this vital work all possible errors due to oversight or fatigue have been eliminated.
  4. Relentless Quality Control
    Often Fisher standards for component material are so high that there is nothing commercially available. Dual controls for stereo use with uniform tracking did not exist in practical form until Fisher engineers set up measuring and testing techniques for our control manufacturers to follow.
  5. Ironclad Packaging
    No matter how fine a product, no matter how carefully it is made and tested, its mission cannot be accomplished unless it reaches you, the user, in the same flawless condition in which the final inspector approved it. The carton in which every Fisher instrument is protected and shipped is itself engineered.
  6. Instruction Manuals
    The moment you see your first Fisher Installation and Operating Manual you will know that it is the most complete and easiest to understand in the entire field. For it was written with affection and respect, written by one who is himself a high fidelity enthusiast, and thoroughly familiar through personal use with the equipment about which he writes.
  7. After-Sales Service
    No matter where you live, you are never far from Fisher parts and service. Replacement parts, should they ever be necessary, are shipped immediately on request. We still have parts on hand for units we made twenty years ago-parts that were never needed, but still wait their turn to demonstrate the true meaning of the Fisher name on the product you buy.
