Xtant2.2/Xtant4.4 Amplifier Owner’s Manual

TROUBLESHOOTING

SYMPTOM: No power

SOLUTION: Check connections to the amplifier’s Ground, B+ & Remote terminals. Check con- nection at “+” terminal of the battery. Check the remote turn-on terminal. Ensure it receives power when the source is turned on (or when the switch is turned on). Refer to the Installation Section. Check the power line fuse: if fuse is blown, replace it; if fuse continues to blow, check the power wire and also the amplifier for a short. If the short is in the power wire, fix it; if the short is in the amplifier itself, see your Xtant dealer.

Check the voltage at the amplifier, and the remote ON/OFF lead. The voltage should measure between 11 V - 15 V. If the measurement is beyond this range, have the source unit checked out by an authorized dealer.

SYMPTOM: Power without sound with red power indicator on

SOLUTION: Turn the amplifier off, and Check all input & output signal cables and connections. Check the speakers for short with a VOM (volt meter) or by connecting them to another audio system. After making sure everything is normal, turn the amplifier on again.

SYMPTOM: Power without sound with orange protection indicator on

SOLUTION: The continuous orange light of the protection indicator signals a high internal operating temperature, which results in the amplifier switching off temporarily; when the amplifier cools down to a safe level, the amp will automatically restart.

SYMPTOM: No sound from one side

SOLUTION: Check balance control. Check speaker connections. Check signal input connection.

SYMPTOM: Very low sound from both radio & other source

SOLUTION: Check your radio’s fader control. Check the amplifier’s Input Sensitivity Level.

SYMPTOM: Frequent automatic amplifier shut down

SOLUTION: This indicates that the amplifier is operating continually at an exceedingly high

internal temperature. High operating temperature caused by inadequate ventilation: Refer to the sub-section titled LOCATION for better amplifier location.

High operating temperature caused by an excessively low impedance load, say below 2 ohms stereo or 4 ohms bridged: Check for bad speakers and/or electronic crossover, proper passive crossover components; if difficulty persists, please consult your local authorized Xtant retailer.

High operating temperature can be caused by an incorrect input sensitivity level: refer to sub- section titled GAIN CONTROL ADJUSTMENTS for correct setting.

SYMPTOM: “Motorboating”: The amplifier power indicator going off repeatedly when the audio system is on

SOLUTION: Check the amplifier’s connection to the battery.

Check battery voltage. If low, recharge or replace battery. Check all ground connections.
