Input Gain Adjustment Control

 

 

 

 

NOM(1.0V)

Set the MRV-F900 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 vol-

 

 

ume 1 step (or until the output is no longer distorted). Now, increase the amplifier gain

GAIN

until the sound from the speakers becomes distorted. Reduce the gain slightly so the
