SERIES EQUALIZERS
Thank you for purchasing a Peavey Electronics Q Series graphic equalizer. The Q family features
two dual-channel models and one single-channel unit, all incorporating Peavey’s legendary low-
noise, low-distortion design. Ruggedly constructed, Q Series EQs have 45 mm, center-detented
control sliders enclosed in metal for durability. These two rack-space units also offer ±15 dB gain
control and an LED display indicating output level. Other shared features include switchable low-cut
filters, +21 dBu balanced inputs and outputs, and bypass switches. Q Series equalizer filters are set
at ISO center frequencies within 3% accuracy. Whether on stage, in the studio, or simply tweaking
your home hi-fi system, the Q Series has an EQ for you.
