Features

Overview: The Atlas AT100RM is a high-quality, rack-mountable volume attenuator rated for up to 100W. The AT100RM works with both 25- and 70-volt commercial systems, and is designed to be rack mounted. The attenuator features ten click-stop positions, plus Off, and includes an adhesive dial-scale overlay with 0 - 10 increments marked around the perimeter.

Optional Rack Plate: The Atlas ATPLATE-052 (sold separately) is a 2U high, 19" wide rack-plate that can accommodate up to 6 Atlas RM series attenuators.

Auto Transformer: The AT100RM 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.
