APPLICATION
Superior styling of WhisperTouch controls combined with their fine-tune level
capability make them ideal for residential/custom installation and professional
applications of all kinds including: private homes, medical and legal offices,
dental groups, studios, and high-profile businesses that demand clear music
reproduction and precise level control.
GENERAL DESCRIPTION
WhisperTouch volume controls provide for clear, distortion-free stereo music
reproduction when one or multiple loudspeaker pairs are powered by a single
amplifier. Model DWT-8 is an 8 ohm device with a decora-style wall plate.
Frequency response is 20Hz - 20kHz (-3dB, +0). Attenuation is accomplished
in ten 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 low-profile knob is pleasant to the touch and adjusts easily. It measures
15
⁄16
" Dia. and projects a mere
1
⁄2
" for unobtrusive yet functional operation. The
control operates smoothly with fine detents and make-before-break contacts
for gradual and un-interrupted transition when changing volume settings. High
quality units require 12 to 18-gauge wire and terminate with convenient plug-in
connectors. Assemblies measure 2
3
⁄4" deep and mount into a standard 20 cu.in.
E.O. Box (by others). Specify plate color: suffix (-I) for ivory or (-W) for white.
