Volume Controls

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.

The AST-6 loudspeaker switching systems include an impedance protection circuit that operates in pairs, allowing each set of loudspeakers to operate directly and simultaneously from the amplifier for maximum efficiency. The left and right channels are completely isolated for protected operation. The AST-6 is 17" W x 1-5/8" H x 5-7/8" D (432 x 41 x 149mm) and can be shelf or 19" rack-mounted, with supplied brackets. Features Euro-style screw terminals that will facilitate 12 to 24-gauge wire, push-button on/off controls for each connection, and attractive mar-resistant black finish. The AST-6 provides overall A or B system selection, but does not include volume controls.

AST-6 provides for switching control of six loudspeaker pairs, and will accommodate any combination of 8 and/or 16 Ohm loudspeakers. Model AST-6 also features a switch for safe connection of 4 ohm loudspeakers. AST devices include separate on/off controls for each loudspeaker pair and one A-B source selector switch for overall system control. Loudspeaker volume can be adjusted using individual room volume controls such as the Atlas Sound DAT-8 or SAT-8 Series (not included). AST-6 has a power handling capacity of 40 watts RMS*/120 Watts audio.
