AtlasIED TSD-MIX31RL 3 x 1 Mic/Line Mixer

The AtlasIED TSD-MIX31RL is a 3 x 1 mic/line mixer. 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. Published frequency response is 20Hz - 20kHz (+/-1dB).

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. AtlasIED lists two (2) balanced mic/line inputs; high gain (50dB) microphone preamps; switchable 24V phantom power; one (1) unbalanced summing dual RCA line input. It measures 1.5" high, 4" wide, and 2.5" deep. It carries a manufacturer warranty of 36 months from date of purchase.
