Deluxe priority attenuator, rack-mounted, 70.7 V, 10 W, with priority relay, 3 dB steps

The high-quality AT10-PARM autotransformer provides the advantages of excellent frequency response, low insertion loss, and reliable performance for volume control applications in 25 and 70.7 volt systems.

Dimming is achieved in ten open-to-pause steps plus a positive off position. (There is no stop between the maximum and off positions to prevent damage to the switch.) The contacts are silver-plated for noise-free operation.

It features a removable terminal block. It includes a silkscreened dial scale and a skirted black knob.



• Attractive matte black polycarbonate dial scale overlay with adhesive backing that replaces the mounting plate. Includes black knob with skirt.
• The priority search function avoids the dimmer effect
• Rack-mount attenuator for mounting on blanking panels in equipment cabinets
• The SPDT relay operates on 24 VDC at 10 mA
