Troubleshooting

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

Front Panel Power Indicator Is Not Lit

No main power to the ampliﬁer. Check AC power connections at the ampliﬁer 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 the Protection Indicator 2 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 conﬁguration.

Protection Indicator Is Lit

The front panel Protection Indicator 2 will light when the ampliﬁer protection circuits have shut off the ampliﬁer. Typically, this occurs only when the ampliﬁer has overheated, when there is faulty speaker wiring, or after a period of extreme use. Turn off the system and wait for the ampliﬁer 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 ampliﬁer itself.
