The QF family features one dual-channel model and one single-channel unit, all incorporating Peavey's legendary low-noise, low-distortion design. Ruggedly constructed, QF 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. QF 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 QF Series has an EQ for you.
