Four Channel Mixer
The module features a clever combination of four output sockets to achieve a variety of uses. Two mix outputs are available: One is MIX OUT and this is simply the four inputs added together - the first three inputs being added according to the levels set by the pots. The second main output is OUT3/MIX. This is exactly the same as MIX OUT until you start connecting jack plugs to either OUT1 and/or OUT2.
