The Atlas Sound DWS-8I WhisperTouch 8-ohm, switched volume control provides clear, distortionfree stereo music reproduction when one or multiple loudspeaker pairs are powered by a single amplifier. The 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.
 
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. It also features 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. THe DWS-81 also features a frequency response of 20Hz - 20kHz (-3dB, +0).
 
Volume adjustments are made easily with the unique WhisperTouch low-profile knob. Pleasant to the touch, this small knob 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 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 2 units, or PS12-10 which will power up to 12 units. Assemblies measure 23/4" deep and mount into a 20 cu.in. E.O. Box such as Carlon Model B120A or equivalent. Specify plate color: suffix (-I) for ivory or (-W) for white.
