APPLICATION
Top-of-the-line, 8-ohm WhisperTouch DWS Series offers superior styling, fine-tune
level control, and an on/off switch for local audio access control. They are the per-
fect choice for residential/custom installation and professional applications of all
kinds including: homes, medical, legal, and dental offices, studios, and high-profile
businesses that expect clear music reproduction and precise level control.
GENERAL DESCRIPTION
WhisperTouch 8-ohm, switched volume controls provide for clear, distortion-
free stereo music reproduction when one or multiple loudspeaker pairs are
powered by a single amplifier. Model DWS-8 is an 8-ohm device with a smart
on/off switch, LED status indicator, and a volume-control knob mounted to 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 “switched” WhisperTouch series features an electronic on/off pushbutton
switch that provides access to the active audio system without going to the
main equipment location. It also turns itself off when the system shuts down,
and remains off until re-selected, thereby avoiding the problem of mass audio
distribution at previous system settings. The “switched” WhisperTouch volume
controls also feature a two-color LED that provides remote visual indication of
system availability. It appears “red” when the audio system is on, changing to
“green” when the volume control is activated.
Volume adjustments are made easily with the unique WhisperTouch low-pro-
file knob. Pleasant to the touch, this small knob measures

" Dia. and proj-
ects a mere

smoothly with fine detents and make-before-break contacts for gradual and
uninterrupted transition of volume levels. High-quality units feature terminal
block conectors for easy hook-up and require a 12 VDC power supply (order
separately). Recommended models include PS-M12 which will power up to 3
units, or PS12-10 which will power up to 12 units. Assemblies measure 2
