It's a Soundtech M660 with the following connectors and speaker outputs:
- Mic In XLR
- Line In 1/4" two conductor (phone) plug
- Aux Returns (1/4" plugs)
- Main Out 1/4" connector
- Tape Out (dual RCA phono output)
- Tape In (dual RCA phono input)
- Rear Panel Main/Monitor Outs (dual 1/4")
- Rear Panel Main Outs (dual 1/4")
The intent is to use the 950 to enable video switching (e.g., projector, laptop, etc.) in conjunction with the public address audio (e.g., mics, headsets, etc.).
Hopefully that makes sense.
