Phoenix Gold TI1600.5 Troubleshooting, No Power, Power Without Sound, Power But Protect Led Is On

Amplifier Owner’s Manual

TROUBLESHOOTING

NO POWER:

Check voltage at amplifier with a DMM (volt meter), +12v and R (with head unit on) the voltage should register between 12.2V and 14.6V when using the ground lead of the amplifier. Check fuse at amplifier and at the battery. Use a meter to verify connection from one end of the fuse to the other, breaks may not always be visible. If the fuse is blown, check the power wire and also the amplifier for a short. If the short is in the amplifier itself, see your Phoenix Gold dealer. If no short is present, replace the fuse.

POWER WITHOUT SOUND:

Turn the amplifier off and check all input and output signal cables and power connections. Check the speakers for shorts with a DMM (volt meter) or by connecting them

to another audio source. After making sure everything is correct, turn the amplifier on again.

POWER BUT PROTECT LED IS ON:

The red PROTECT LED lights when the amplifier shuts down for either thermal or over-current protection. A high internal amplifier operating temperature will trigger thermal shutdown: after it cools about 5°C, the amplifier will restart.

A shorted speaker lead or operation into unusually low impedance loads will trigger over-current shutdown: cycle power at the amplifier remote terminal to restore operation. Check for shorted speaker wiring or damaged speakers or crossover systems if over-current shutdown occurs.

NO SOUND FROM ONE SIDE:

Check the balance control in the head unit. Check speaker connections. Check signal input connection.

VERY LOW OUTPUT:

Check your head unit’s fader control or the amplifier’s input sensitivity level. Make sure subsonic frequency control is not set too high and LP frequency control is not set too low at the same time.

FREQUENT AMPLIFIER SHUTDOWN:

This indicates chronic amplifier thermal shutdown because of operation at consistently high internal temperatures. High operating temperature can be caused by inadequate ventilation. Make sure you are not running a lower than recommend impedance. Also check for damaged speakers or passive crossover systems. Finally, chronic thermal shutdown may result from otherwise normal operation of the amplifier at elevated output power levels, which can be resolved by providing additional amplifier cooling, installing a higher-power amplifier, or reducing amplifier output level.

AMPLIFIER QUICKLY CYCLING ON AND OFF: Check the amplifier’s connection to the battery. Check battery voltage. If low, recharge or replace the battery. Check all ground connections.
