Atlas Sound TSD-MIX31RL Overview

The Atlas Sound TSD-MIX31RL 3x1 Mic/Line Mixer includes two mic/balanced line inputs via removable Phoenix style connectors and a stereo summing dual RCA input. Switchable phantom power is provided for both mic inputs to facilitate condenser microphones. The low noise internal mic preamps ensure clarity and quiet operation without unwanted coloration. A 12dB/octave high pass filter at 125Hz also is available on each input to minimize bass rumble and low frequency feedback.

Priority paging can be accomplished via contact closure or VOX trigger on Input 1 (mutes input 3 only). Remote level control feature allows use of an optional decorative wall plate control for remote adjustment of either the entire mix bus or input 3 only (typical BGM input).

A variable output limiter provides system protection by reducing clipping and distortion. The TSD-MIX31RL requires a power supply (not included) for operation.
