The Davis AT-Series auto-transformers permit the volume level control of a loudspeaker, or group of loudspeakers (a "zone"), connected on 70 volt or 25 volt speaker systems.  In addition to providing control of groups of loudspeakers, this easily accessible wall mounted control is the ideal choice for professional offices where appearance and individual preferences need to be accommodated. 

The desired level and quality of sound reproduction is assured by the 10 position attenuation, wide frequency response and lower insertion loss.  

Installation is facilitated by mounting in a single gang electrical box and the solderless, detachable Quick Connect "Phoenix" type connector.

The AT Series offers a broad range of options with power rating from 20 watts to 100 watts, 70/25 volt line inputs-outputs, and either the standard stainless steel cover or the attractive off-white plastic snap-on cover with hidden screws.
