APPLICATION
Superior styling of the MUSICAVC-50Z volume control combined
with its fine tune level capability makes it ideal for residential/
custom installation and professional applications of all kinds in-
cluding: private homes, medical and legal offices, dental groups,
studios, and high-profile businesses that demand clear music re-
production and precise level control.
GENERAL DESCRIPTION
The MUSICAVC-50Z volume control provides clear, distortion-
free stereo music reproduction when one or multiple loudspeaker
pairs are powered by a single amplifier. MUSICAVC-50Z is an 8
ohm 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.
INSTALLING
1) Pull off the plastic knob from the shaft.
2) Remove the trim piece by compressing the four tabs on the
back side of the metal plate.
3) Slide the hole in the desired color trim plate over the shaft and
press the four tabs into the back side of the metal plate.
4) Push the desired color knob onto the shaft, taking care to in-
sure that the flat in the knob lines up with the flat on the shaft.
5) Install the desired color decora-style plate with the matching
finishing screws.
