Amplifier Owner's Manual
TRI-LIGHT
Troubleshooting is made easy thanks to the Tri-Light status
indicators. If amplifier is not working, reference these first to
access current status and address as needed.
Tri-light LED amplifier status indicators will change colors
according to an array of system variables.
No Illumination - No Power
Blue - Standard Operation
Green - Over Voltage Warning/Thermal Protection
Red - Internal Fuse Blown
Amber - DC/Short Protection
NO POWER:
Check voltage at the amplifier with a DMM (volt meter),
+12v and R (with head unit on) the voltage should register
between 11.5V and 16.1V when using the attached ground
lead of the amplifier. Check that the amplifier's ground
is good and has a solid connection. Check fuse 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.
GREEN LED ILLUMINATED:
Check charging system for cause of high voltage.
Measure with DMM and verify voltage is not exceeding
16.1V with vehicle running and RPM above 2000. For thermal
protection, check for adequate ventilation or if restricted
ventilation, may require addition of fans.
BLUE LED ILLUMINATED, NO 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.
How to determine if your source (last component sending signal to
amplifier) is a balanced or unbalanced signal:
For car audio, we use standard RCA connectors with 2 main connection
points, the center pin and the outer connector. RCA connectors can be
used in both Balanced and Unbalanced systems.
Unbalanced benefit from the use of Coaxial constructed cables, and in
contrast Balanced systems benefit from Twisted Pair construction. These
are not to be confused with XLR Pro Audio Balanced connectors that
have 3 conductors and are a different type of balanced connection.
This is a simplified explanation, but suitable enough to determine the
type of system you are working with. In an Unbalanced system, the outer
part of the RCA will reference to ground.
To test, use your DMM set to continuity and hold one lead to chassis
ground and the other to the outer RCA connection on your source. If
you read continuity, then your system is Unbalanced and you can adjust
your settings and RCA construction type to suit this style. If there is no
continuity then the system is Balanced and again you can adjust for this
system.
High Level Inputs:
If utilizing high level inputs select Balanced as the input type. Then use
a standard RCA cable with one side cut off to connect source output
wires. Then connect the RCA side to the input of the amplifier. The input
is capable of accepting up to 16V of input signal.
RED LED ILLUMINATED:
Internal Fuse Blown, visit an authorized dealer for service and
troubleshooting. The advanced design of the SX2 amplifiers should
protect the amplifier in almost every circumstance, a blown internal
fuse is a red flag meaning that something out of the ordinary is
happening and should be investigated before replacing fuse.
Example would be external fuse used is higher than recommended
value.
AMBER LED ILLUMINATED:
DC/Short Protection. Check all connections. Disconnect all speaker
wires and restart amplifier. If status returns to Blue, then meter
speaker leads and verify not shorted to one another or to ground.
Reconnect speaker leads and retest.
BLUE LED ILLUMINATED, NO SOUND FROM ONE OR MORE CHANNELS:
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 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.
POWER CYCLES ON/OFF QUICKLY:
If the power indicator if going off repeatedly when the audio system is
on, check all ground connections. Check the amplifier's connection
to the battery. Check battery voltage. If low, recharge or replace the
battery.
