Switch Settings - Alpine MRV-M1200 Owner's Manual

SWITCH SETTINGS

NOTE:
• Before switching each Selector Switch, turn off
the power and insert a small screwdriver, etc.,
perpendicularly to the Switch.
Input Gain Adjustment Control
Set the MRV-M1200 input gain to the minimum
position. Using a dynamic CD as a source,
increase the head unit volume until the output
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 becomes distorted. Reduce the gain
slightly so the sound is no longer distorted to
achieve the optimum gain setting.
Crossover Frequency Adjustment Knob (LP
FILTER)
Use this control to adjust the crossover
frequency between 50 to 400 Hz.
Bass EQ Adjustment Knob
Add a 50 Hz bass boost up to +12 dB to tune
your bass response.
