The 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 high quality, low noise internal mic preamps ensure clarity and quiet operation without unwanted coloration. A 12dB / octave high pass filter @ 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 the AAVC-10K (or equivalent) decorative wall plate control for convenient 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 - which is especially useful when mixing multiple mics and/or line sources with varying volumes.
