This switch controls Peavey’s exclusive DDT (Distortion Detection Technique) speaker protection. With
this switch in the OUT position‚ a unique circuit senses signal conditions that might overload the
amplifier and activates compression to reduce gain and avoid clipping. This technique utilizes every watt
available for the amplifier to reproduce the signal‚ yet minimizes clipping and distortion which reduces
the potential for speaker damage. Since this function is “invisible” at levels below the clipping point‚ it is
advised that it be activated at all times. Setting this switch to the IN position defeats this protection
feature‚ allowing potential power amp clipping and the resultant increase in likelihood of speaker
damage.

This 3-position‚ rocker-type switch should normally be placed in the center (0) position. If hum or
noise is noticed coming from the speaker enclosure‚ the switch may be placed in the (+) or (-)
position to minimize hum/noise. If changing polarity does not alleviate the problem‚ consult your
authorized Peavey dealer‚ the Peavey factory or a qualified service technician.
