stereo (standard output of 500 mV), set to
the NORMAL position. When using with
an RCA equipped Pioneer car stereo with
max. output of 4 V or more, adjust level to
match the car stereo output level.
If the sound level is too low, even when
the volume of the car stereo used along

turn gain control on the front of the
power amplifier clockwise. If the sound
distorts when the volume is turned up,
turn the gain control counter-clockwise.
