Input Gain Adjustment Control
Set the MRP-M650/MRP-M450 input gain to the
minimum (4V) position. Using a dynamic CD as a
source, increase the head unit volume until the out-
put distorts. Then, reduce the volume 1 step (or until
the output is no longer distorted). Now, increase the
amplifier gain until the sound from the speakers be-
comes distorted. Reduce the gain slightly so the
sound is no longer distorted to achieve the optimum
gain setting.

Boost the low frequency output of the amplifier from
0 dB (flat) to +12dB. Adjust the Bass EQ (centered at
50 Hz) to suit your personal taste.
