User manual CARVIN DCM1000

[. . . ] CARVIN ENGINEERING DATA DCM600, DCM1000 POWER AMPS OPERATING MANUAL with extra hot input signals (this protects your expensive speakers). In addition, a well designed limiter can increase your amp's average output as much as 3 db. Part of Carvin's design uses the more expensive, distortion-free linear "opto isolators". Unlike amps that use FET controlled limiters which can inject small amounts of distortion, the DCM Series limiters keep your sound pure and uncolored! DCM600, DCM1000 The DCM Series professional amps are designed utilizing Carvin's 35 years of experience in power amp technology.

If hum is not eliminated, then use a 600 line input transformer cutting the input ground on the connectors (Pin 1). This isolates the input ground from the AC power ground eliminating a system ground loop. 5) POOR SOUND (BASS): The speaker systems are wired out of phase to each other. To correct, reverse the wires on one speaker connector only and your bass response will improve. 6) THE AMP'S REAR CIRCUIT BREAKER TRIPS: When the red CLIP LEDs are flashing at 2 (4 bridged), the rear circuit breaker may trip. 7) MAIN AC BREAKER TRIPS: Each high powered amp may require a separate 20 amp circuit breaker (230V: 10 amp) for delivering full power. Note: Some 120V homes have only 15 amp breakers.
