WARNING! For optimum performance and reliability DO NOT PRESENT THE AMPLIFIER WITH A SPEAKER LOAD OF LESS THAN 2 OHMS, OR ACOMBINATION OF SPEAKERS THAT TOGETHER ARE LESS THAN 2 OHMS! Using one speaker, it must be rated at 2 ohms minimum. Using two speakers, they must be rated each at 4 ohms minimum....

PROFESSIONAL STEREO POWER AMPLIFIER ACTIVE (1) The active indicate when compression is taking place. As long as gain reduction is occurring, the LED will continue to light, thereby giving a valuable indication of this unique compression function. The DDT function can be defeated on both channels sim...

Operation at loads of 4 ohms per channel or 8 ohms BRIDGE mode is more desirable for sustained operation applications, be- cause the amplifier will run much cooler at this load. Operation above 4 ohms per channel andeven open-circuit conditions ...

If individual loads were connected to each output (as in normal stereo applications) when the bridge mode is selected. Channel A would supply a normal in-phase signal to its respective load, but Channel B would supply ...

normal intermittent applications, low-speed fan operation will provide adequate cooling. Since the CS 1200X is a redundant two-channel amplifier, but only one fan is employed, the fan circuitry is an independent system, separately fused internally. You will notice that the heat sinkcomponents are di...

The result usually is severe clipping (distortion) of the high-frequency material. In a biamplified system, the high-frequency material is routed to its own power amplifier (and associated loud-speaker), which avoids the clipping problem. This results in an effective increase in system headroom that...
