Troubleshooting
CONDITION: Distorted sound.
POSSIBLE REASON:
• Load is wired incorrectly or Stereo/Bridge
mode switch is set incorrectly. Check both.
• Input is overloaded by a signal level that is
too high. Turn down your amplifier level
controls, or turn down the input signal, until
the clip light goes out.
Note: If the signal sounds distorted even
though the Clip LED is off, the input signal
may be dis torted before it reaches the
amplifier input. Check gain staging and
output levels of the mixer or preamp.
“Off/Flashing/On” above means that
the LED can be off, or flashing, or on.
CONDITION: No sound, even
though the amp has power. Power
LED is on with out flashing and the amp is
receiving an input sig nal. Signal indicator
is flashing.
POSSIBLE REASON:
• Speakers not connected.
• Open circuit due to speaker failure.
• Based on the front panel LEDs, determine
which channel has a short. Remove the
associated input connector to ensure that no
voltage will be present on the output. Remove
the shorted load (and possibly attached
cables) and have it checked by a qualified
technician. If the shorted condition remains
after the load is removed, the unit should be
sent into a qualified service center.
• Ready LED is off. Channel has been set to
Sleep mode via the Aux port or Power
Save mode.
