Amplifier Owner’s Manual

SYSTEM TUNING

1.Install all system fuses.

2.Set the amplifier’s input sensitivity controls to their minimum positions (full counterclockwise).

3.Set all amplifier crossover switches according to your system’s design.

4.Make preliminary adjustments to the crossover frequency, usually 80Hz is good starting point for low pass and 30Hz for subsonic. It may be necessary to fine 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 amplifier’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 (flat) position. Turn off 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 amplifier until the speakers reach maximum undistorted output. The clip LEDs should flash with the peaks of the music at this level.

12.Repeat sensitivity level adjustments for all other amplifiers.

13.Reduce the headunit’s volume to a comfortable level.

14.Listen to various musical selections to check overall system balance. 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.

Note: For subwoofers controlled by the Remote level control, keep the level setting from step 11 or 12. Use the control to blend subwoofers with the rest of the system. The correct subwoofer volume will change depending on road noise and differences in recordings.

15.Fine tune crossover frequencies to achieve the smoothest possible blending of each speaker set.

16.Adjust the Bass Equalization Controls on the amplifier, headunit or 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.

17.With all levels set correctly, the system will reach overall maximum undistorted output at the volume level set in step 10.

TROUBLESHOOTING

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 14.4V when using the attached ground lead of the amplifier. 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.

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, NO Sound, Protect led 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 R terminal to restore operation. Check for shorted speaker wiring or damaged speakers or crossover systems if over-current shutdown occurs.

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:

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.
