Amplifier Owner's Manual
Troubleshooting
No power: Check voltage at amplifier with a DMM (volt meter), B+
and REM (with head unit on) the voltage should register between
12.2V and 14.6V when using the attached 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.
"Motor Boating" - the power indicator going off repeatedly when
the audio system is on: Check the amplifier's connection to the
battery. Check battery voltage. If low, recharge or replace the
battery. Check all ground connections.
Power without sound and the PROTECT LED is lit: 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 REM 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 HP frequency control is
not set too high and LP frequency control is not set too low at the
same time.
Frequent amplifier shutdown with automatic recovery: 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.
No sound from amplifier using Bluetooth: Verify Bluetooth is on and
connected with PGBTM51. Verify power lite is illuminated blue on
PSX350.2
If still no audio, turn off Bluetooth from media device, if sound
now plays from media device, try turning Bluetooth back on from
media device.
No sound from amplifier using RCA or Line level input: Verify
Bluetooth is off on any paired Bluetooth device. Bluetooth is
primary source, RCA or line level inputs are not active when
Bluetooth device is connected, even if not actively streaming
content.
