DIP switch
This board includes a 6-pin DIP switch that controls up to three settings, labeled ❶, ❷,
and ❸ below. On some amp models, the MC/MM selection (❶) is operated directly from
the amp's control panel. On these models (see below), the DIP switch setting for ❶ is
meaningless. Please refer to the table below, and set the DIP switch accordingly.

Do not put anything other than the board into the slot. Inserting fingers or objects may cause
equipment failure.
●
Do not touch the board's components, soldered areas, or connector pins, as doing so may cause
equipment failure. Hold the board at the edges or by its panel.
