Ddt Compression - Peavey CS 1800 G Operating Manual

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.
