Troubleshooting

Most diffi culties in audio systems are the result of poor or wrong
connections, or improper control settings. If you encounter problems,
isolate the area of the diffi culty, check the control settings, determine
the cause of the fault and make the necessary changes. If you are
unable to get sound from your amplifi er, refer to the suggestions for the
following conditions:

Front Panel Power Indicator Is Not Lit

No main power to the amplifi er. Check AC power connections at the
amplifi er and the AC outlet. Check the front panel power switch. Make
sure that it is set to the ON position. If using 12V trigger power-on,
make sure that a trigger signal is present at rear panel 12V TRIG IN
jack.

No Sound

If the amp is getting AC power, but is producing no sound, check
2
the Protection Indicator on the front panel. If lit, see below. If
not, check all of your connections and control settings on associated
components. Make sure that your input connections and speaker
connections match your system confi guration.

Protection Indicator Is Lit

The front panel Protection Indicator
protection circuits have shut off the amplifi er. Typically, this occurs
only when the amplifi er has overheated, when there is faulty speaker
wiring, or after a period of extreme use. Turn off the system and wait
for the amplifi er to cool. Then push the front panel power switch in
and out to reset the protection devices. If the problem is not corrected
or reoccurs, there is a problem with the system or the amplifi er itself.
