System tuning
1. Install all system fuses.
2. Set the ampli er's input sensitivity controls to their minimum positions
(full counterclockwise).
3. Set all ampli er crossover switches according to your system's design.
4. Make preliminary adjustments to the crossover frequency, usually 80Hz
is good starting point for high and low pass. It may be necessary to ne
tune the crossover frequency later for the best overall sound quality.
5. If using a Remote Subwoofer Level Control, set it to maximum (full
clockwise).
6. Turn the headunit on with the volume set to minimum.
7. Visually check the ampli er's has turned on by the power LED.
8. Check the condition of all other components to make sure they are
powered up.
9. Set the headunit's tone controls, balance, and fader to the center ( at)
position. Turn o any loudness or other signal processing features.
10. Set the volume control of the headunit to 3/4 of maximum volume. Play
music you typically listen to through the system.
11. Turn up the sensitivity or input level control on the ampli er until the
speakers reach maximum undistorted output.
TROUBLESHOOTING
NO POWER:
Check voltage at the ampli er with a DMM (volt meter), +12v and R
(with head unit on) the voltage should register between 11.5V and
14.4V when using the attached ground lead of the ampli er. 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 ampli er for a short. If
the short is in the ampli er itself, see your Phoenix Gold dealer. If a
short is not present, replace the fuse.
POWER WITHOUT SOUND:
Turn the ampli er o 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 ampli er on again.
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 ampli er's input sensitivity
level.

12. Repeat sensitivity level adjustments for all other ampli ers.
13. Reduce the headunit's volume to a comfortable level.
14. Listen to various musical selections to check overall system balance.
15. Fine tune crossover frequencies to achieve the smoothest possible
16. Adjust the Bass Equalization Controls on the ampli er, headunit or
17. With all levels set correctly, the system will reach overall maximum
FREQUENT AMPLIFIER SHUTDOWN WITH AUTOMATIC
RECOVERY:
This indicates chronic ampli er 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 ampli er at elevated output
power levels, which can be resolved by providing additional
ampli er cooling, installing a higher-power ampli er, or reducing
ampli er output level.
POWER CYCLES ON/OFF QUICKLY:
The power indicator going o repeatedly when the audio system is
on. Check the ampli er's connection to the battery. Check battery
voltage. If low, recharge or replace the battery. Check all ground
connections.
Compare front to rear, midbass to midrange, etc. If one speaker set is
too loud compared to another, then its level must be lowered to blend
correctly with the other speakers.

processor upstream if necessary to increase output.
Note: Use these controls sparingly. Every 3dB of boost requires double the
power at 45Hz. If your subwoofer system requires a lot of boost to sound
good, there may be a problem. Look for out-of-phase woofers, a leaking
subwoofer box, or incorrect box size.
