High-quality auto transformer series provides the advantages of excellent frequency response, low insertion loss and reliable performance for volume control application in 25 and 70.7-volt systems. Attenuation is accomplished in ten make before break steps plus positive off position. (No stop between maximum and off position to prevent switch damage). Contacts are silver plated for noise-free operation. Features a removable terminal block. Includes stainless steel plate, with stamped and filled or screen printed dial scale and a skirted black knob. (White and ivory plastic plates with matching skirted knobs also available in Decora style-see AT model description chart.)

Priority paging feature by-passes the attenuator dial setting to provide full program level to the loudspeakers. Option is available on all AT attenuators. The SPDT relay is operated with 24 VDC at 10mA. Includes protective relay cover to insure lasting trouble-free performance. Terminations to the relay and attenuator are made via a removable terminal block. (All other specifications except for dimensions are the same as selected AT models.
