Do not increase any “Input Sens.” setting for any amplifier channel or
channel pair in the system beyond the maximum level established during
this procedure. Doing so will result in audible distortion and possible
speaker damage.
It will be necessary to re-adjust the “Input Sens.” for the affected channels if any
equalizer boost is activated after setting the “Input Sens.” with this procedure. This
applies to any EQ boost circuit, including source unit tone controls or EQ circuits. EQ
cuts will not require re-adjustment.

Remote Bass Control
With the optional RBC-1 or M-RBC-1 Remote Bass Control (each sold separately),
you can control the subwoofer volume from the front of the vehicle/vessel.
The remote’s plug connects to the amplifier’s harness-mounted RJ11 input
jack. When connected to the amplifier, the Remote Bass Control operates as
follows. At full counter-clockwise rotation, the audio will mute completely. At full
clockwise rotation the level will be the same as if the remote was not connected
at all. In other words, it operates strictly as a subwoofer level attenuator. This
control will not affect the “Bass Boost” feature of the amplifier. Care should
be taken to securely mount this control in a manner that does not interfere
with vehicle/vessel operation. When setting the amplifier’s input sensitivity,
the Remote Bass Control should be unplugged or at full clockwise rotation
(maximum level).
