Peavey CS 1800G manual Ddttm Compression

DDTTM COMPRESSION

Peavey’s patented DDTrM compression system enables the sound man to maximize the performance of the amplifier/ speaker combination by preventing the power amp from running out of headroom (clipping). This compression system is activated by a very unique circuit that senses signal conditions that might overload the amplifier and activates compression (reduces the amp gain) when clipping is imminent. Threshold of compression, then, is clipping itself and no specific threshold control is used. This technique effectively utilizes every precious watt available for the power amplifier to reproduce the signal while at the same time minimizes clipping and distortion, and thus significantly reduces the potential of loudspeaker degradation and damage. The DDT system is an automatic, hands-off approach to the problem of power amplifier clipping. Since the CS 1800G power amplifier uses circuit breakers for the over-current protection, the DDT compression system plays even a more important roll in continuous performance by preventing each channel from clipping and overloading. Continuous operation at clipping can cause the circuit breaker to trip, but with the DDT activated, this problem is minimized. For this reason you should always have the DDT compression system enabled.
