troubleshooting

If you are having trouble with your amplifier, check

the following items.

No sound

Check the following:

The P429 power amplifier is correctly plugged in

and switched on

Your audio/video source (e.g. preamplifier) is

correctly connected, the correct input is selected

and it is not muted

The P429 is not in protection mode, as described

in the next section.

Sound cuts-out unexpectedly

The P429 may enter a protection mode, depending

on the fault being detected. The front panel LED will

indicate the fault type, according to the following list:

ALTERNATE RED/GREEN: The internal

temperature of the unit reached an unsafe level.

Allow the P429 to cool off.

FLASHING RED: The P429 amplifier detected a

speaker short circuit. Should this happen, please

inspect all the speaker cables to make sure none

of them are shorted together. This fault is very

common when bare wires are being used to make

speaker connections.

FLASHING ORANGE: The amplifier detected a

DC offset.

Following any of the faults described above, the

amplifier will turn itself off and power to the speakers

will be removed. To continue using the P429, the fault

must be removed and the unit must be turned OFF

then back ON.
