DDT®
Peavey’s patented DDT (Distortion Detection Technique) compression circuit enables the sound techni-
cian to maximize the performance of the amplier/speaker combination by preventing the power ampli-
er from running out of headroom (clipping). This fully automatic compression system features a unique
circuit that senses signal conditions that might overload the amplier. It activates compression (reduces
the channel gain) when clipping is imminent. The threshold of compression is clipping itself, and no
specic threshold control is used. This technique effectively utilizes every precious watt available for
the power amplier to reproduce the signal, while at the same time minimizing clipping and distortion.
DDT signicantly reduces the potential of loudspeaker degradation and damage, and is the most effec-
tive, automatic, hands-off approach to the problem of power amplier clipping. Since PV series power
ampliers use a circuit breaker for overcurrent protection, the DDT compression system plays an even
more important role in continuous performance by preventing each channel from clipping and overload.
Continuous operation at clipping can cause the circuit breaker to trip, but with the DDT activated, this
problem is minimized.
