SoundMaster MM-2 four channel mini mixer from the SR-88 & Stix era. Each channel has a gain switch to select between "Mic", "Line" and "Instrument" inputs, a tone control and a level fader. Overall output level is set with the master level fader. Inputs and outputs are standard 6.35mm jacks. Unit runs on a single 9v battery or a DC power supply. Condition is good with very minor age related wear. A nice collectors item for SR-88 owners.
