This is the power supply for the ToneMatch Mixer[1].

Not Required with L1 Pro[2]

The L1 Pro[2] systems have a ToneMatch port that can supply power to any ToneMatch mixer.


Required with Earlier Systems except L1 Model II

You will need this to power your ToneMatch Mixer[1] when running with an L1 Compact, S1 Pro System, L1 Classic, L1 Model I, or non-Bose equipment. You will need a one of these if you have two ToneMatch Mixer[1]s running into a single L1® Model II or L1® Model 1S. — details below the picture.
