Amplifier Visual Troubleshooting - Orion XTR500.4 Owner's Manual

slight distortion and turn the level control back slightly for an
undistorted output. Depending on your system, the midrange
and tweeter output may be on the same output channels.
6. Turn up the level control corresponding to the tweeter output
until you hear slight distortion and turn back the level control
slightly for an undistorted output. Depending on your system
the midrange and tweeter output may be on the same output
channels.
7. Fine-tune the output level between midrange and tweeters.
Refer to the Internal Crossover Configuration section of this
manual for detailed instructions.
8. Repeat Steps 5-7 for the rear speakers. If you do not have rear
speakers continue to Step 10.
9. Set levels between the front and rear midrange and tweeters for
optimum front/rear balance.
10. Turn up the level control corresponding to the woofer output
until you hear slight distortion and turn back the level control
slightly for an undistorted output.
11. Fine-tune the output level between satellite speakers and the
woofers. Refer to the Internal Crossover Configuration section
of this manual for detailed instructions.
12. Enjoy your awesome Orion sound system.

Amplifier Visual Troubleshooting

Your new XTR amplifier has three indicator lights (LED's) mounted
on the top plate of the amplifier as seen in the next figure. These
lights are very useful in trouble shooting possible amplifier problems
and issues.
Power LED: This LED lights up green when the amplifier is turned
on. This represents normal operation if the Protection and Thermal
LED's next to it are off.
Protection LED: This LED lights up red if the amplifier goes into
protection. Below is a description of reasons the amplifier could
engage the protection circuit. The protection indications will self
reset once the condition has been fixed.
• Short: Speaker wires pinched or shorted together or to ground
(frame of vehicle).
• Overcurrent: Check for possible speaker issue(s) or speaker
wiring pinched in a door or other metal. Make sure speaker(s)
load is not below the minimum impedance load.
• DC Offset: This can happen if the installation inadvertently
connects the power wire to the speaker input(s). This can also
happen if the amplifier has an internal problem.
• Under voltage: Vehicle charging system is not supplying enough
voltage to the amplifier. This can also occur if you use too small
a gauge wire or the terminals connecting the amplifier power to
the electrical system are dirty or corroded.
