The MUSICAVC-100Z volume control provides clear, distortion free stereo music reproduction when one or multiple speaker pairs are powered by a single amplifier. MUSICAVC-100Z is an 8? device with a decora-style wall plate supplied in three colors to match virtually any decor. Frequency response is 20Hz - 20kHz (-3dB, -0). Attenuation is accomplished in eleven steps plus positive off. The first six steps are 3dB for fine tune control at low listening levels, the next three steps are 6dB, followed by one 9dB step and finally one 28dB step before "off". The control knob measures 1-1/4" DIA. and projects a mere 11/16" for unobtrusive yet functional operation. Assemblies measure 2-11/16" deep and mount into a standard 20 cu. in E.O. Box (by others). Each volume control is supplied with matching plastic parts in white, ivory, and almond. These parts include the plate, knob, and trim piece. The volume control can be changed to the color of your choice by changing out all three plastic parts.
