Troubleshooting

Your Outlaw Multi-Channel Amplifier is designed for trouble free operation. If you follow the instructions in this manual you should enjoy many years of high quality listening enjoyment. However, as with any sophisticated electronic device, there may be occasional problems upon initial installation, or during the life of the unit. The items on this list are a brief guide to the minor prob- lems that you may be able to correct yourself. If these solutions do not rectify a problem, or if the problem persists, contact us for assistance.

Protection Circuitry

Your Outlaw Audio Amplifier uses advanced protection circuitry that does not require fuses. In the event that the amplifier senses a shorted speaker wire, DC voltage on an input connection or thermal overload creates a condition that could potentially cause damage to the unit or to your speakers, it will automatically shut down.

If this should happen, first check all speaker wire connections, both at the speakers themselves and at the speaker terminals on the back of the Model 7500 to make certain that none of the stands from any channel touch another channel, and that none of the strands from a "positive" terminal touch those from a "negative" terminal. Even a few stray wire strands can cause the unit to go into the protection mode.

After checking all speaker connections, turn the unit back on. If it continues to turn off, check your speakers to verify that they are operating properly. If all other potential sources of trouble check out properly, contact Outlaw Audio for further assistance and information.

A Few Words About Hum and Noise

Audible hum, or a discernable low frequency noise, is one of the most com- mon problems in audio/video systems. This hum, which may be present even when the volume is at a low level or when the power is off, is usually caused by a problem known as “ground loops”. A ground loop occurs when there is a difference in ground voltages between two or more components that are con- nected electrically. This, in turn, creates multiple current paths and causes the low-level noise, or hum.

The growing sophistication of home theater systems, and the increased number of components used to create these systems has dramatically increased the potential for the possibility of ground loops. While it is natural to suspect that the components in your system are the cause of the hum, in many cases the cause may be due to other conditions. In particular, cable TV connections from outside the house have become a major source of hum.

In most cases, one of the following suggestions should help you to solve a hum problem in your system. Please try these steps in the sequence shown, proceeding from one step to the next if the prior suggestion does not eliminate the problem.
