Der CROWN M600 - ein gewaltiges Kraftwerk

Prospekt ID : 154 * 6-74

Laut Beschreibung ist diese Verstärker-Konzeption um 1974 aus dem DC300A entstanden. Mit einer Ausgangsleistung von 600 Watt an 8 Ohm und 1.000 Watt an 4 Ohm schlägt er alles Dagewesene. Und wenn man zwei dieser Boliden zum M2000 koppelt, dann wird alles richtig gut und kraftvoll.

CROWN M600 POWER AMPLIFIER

Die Rückseite

The Crown M600 power amplifier provides high power levels and an adaptable format intended for the varied needs and operating environments of industrial and commercial audio users.

While maintaining the exacting laboratory performance standards of the DC300A, the M600 produces 600 watts (monaural) into an 8 ohm load, and 1000 watts into a 4 ohm load. Built for durability and trouble-free operation, the M600 includes built-in cooling which permits continuous full power operation.

Also included is a plug-in input board which provides space and foil layout for standard integrated circuits which can be used as the basic elements for a preamplifier, bandpass filter, or other signal shaping circuit which become a built-in part of the amplifier.

Vom DC300A abgeleitet

The output stages of the M600 employ features similar to other Crown amplifiers, such as the protection circuitry of the DC300A, which allows the amplifier to drive highly reactive and low impedance loads without adverse effects. In addition the M600 employs a newly-patented output bridge circuit, which permits extremely high power levels to be safely sustained. The standard output of the M600 is 70 volts unbalanced.

Coupling two M600's together through a socket provided at the back of each amplifier produces a 140 volt balanced output. This configuration is called an M2000, and produces 2 kilowatts into an 8 ohm load. A peak-catching meter, and threshold lights provide convenient front panel output monitoring.

Input Plugins: The standard plug-in contains an AC-DC input coupling capacitor and switch, a gain control potentiometer, and a universal PC layout which may be adapted for input peripherals such as: differential imputs, filters, oscillators, servo amplifiers, remote DC gain controls, compressors, digital controlers, etc. Regulated ±15 VDC supplies are provided with the maximum total available current of the supplies limited to 25ma. The delay mode of amplifier operation may be programmed from the plug-in.
