Features

Overview: The Atlas AT100D is a deluxe, plate-mounted volume attenuator. It comes with a Decora style wall plate in white and ivory with matching skirted knobs, which is a more attractive alternative to metal commercial attenuators. The UL-listed AT100D works with both 25- and 70-volt commercial systems, and fits into most 1-gang electrical boxes (2.75" deep). The attenuator features ten click-stop positions, plus Off.

Auto Transformer: The AT100D commercial volume control features a high-quality auto transformer with excellent frequency response, low insertion loss and reliable performance. Attenuation is accomplished in steps of 3dB each, plus a positive Off position, for a total attenuation of 27dB. To prevent switch damage, there is no stop between the maximum and Off position. The contacts are silver-plated to eliminate noise and contact loss.

Terminal Blocks: The Atlas AT100D has a removable terminal block with Phoenix (Euroblock) connectors. The terminal blocks will accept up to 16AWG stranded wire.
