NO SOUND
Check all connections. Check main power fuses. Check accessory fuse. With a
trouble light or meter, be sure +12v is present at the amplifier on the power wires
and the red/white turn-on wire. Check for a good ground connection. Check by
substitution, or other method, for proper operation of music source.
BLOWS FUSES
check all connections to be sure power wires and speaker wires do not touch
each other or ground. Re-check polarity of main power wires. Check impedance
of speaker loads and setting of the internal power taps to insure proper match.
SHUTS OFF
As this amplifier is equipped with thermal and short circuit shut-down electronics,
in the event of high ambient temperature or improper speaker impedances, the
amp will turn itself off. To avoid damage to speakers, turn down the volume while
waiting for the amp to turn itself back on. If this occurs repeatedly, use a fan to
cool the amplifier and check for proper speaker loads and connections.
