Peavey's patented DDT (Distortion Detection Technique) compression circuit enables the sound
technician 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 unique circuit
that senses signal conditions which 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 minimizing clipping and distortion and
thus significantly reducing 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 PV Series power
amplifiers use circuit breakers for "over current" protection, the DDT compression system plays even a
more important role in continuous performance by preventing each channel from clipping and overload.
Continuous operation at clipping can cause the circuit breakers to trip, but with the DDT activated, this
problem is minimized. For this reason, you should always have the DDT compression system
enabled.
