Amplifier Operation

After all connections have been made, you are ready for listening. First, turn on
the source components and processor in your system. Adjust your controller or
preamp to a low volume level to avoid damage to your speakers. Next, push the
two Master Power switches on the back of the amplifier to the on position. It is
always a good idea to turn on your amplifier LAST. This avoids the possibility
of any pops or transients from other equipment being amplified and sent to
your speakers where they may cause damage.

Manual On

To turn the amplifier on manually, press the front panel Power/Standby button.
After approximately 25 seconds, the unit will power up and the indicator light
will change to blue. This delay is intentional, and protects your speakers from
damage while the amplifier stabilizes. You may also hear a relay click during
start up. This is also normal.
To turn the unit off, press the Power/Standby button again. The indicator light
will change to orange.

Automatic On

Make certain that the connection to the processor, or other controlling device is
correct, as shown on page 5. Whenever the controlling device is turned on, the
amplifier will automatically turn on after a short pause. This pause is inten-
tional, and it protects your speakers from damage while the amplifier stabilizes.
You may also hear a relay click as during start up. This is also normal.
To turn off your amplifier, simply turn off the unit that feeds the amplifier it’s
audio signals. The amplifier will automatically go into standby mode and the
indicator light will change to orange.

Output Settings

All volume and level adjustments are made at your preamp, controller or sur-
round processor. To assure proper sound field imaging, it is always a good idea
to re-set the output levels of the channels on your processor when using the
amplifier for the first time. The circuitry in your new amplifier may be different
from your previous one, and by checking the output levels you will make certain
that the processor, amplifier and speakers are properly matched.

Care and Maintenance

Cleaning

When the unit becomes dirty, wipe it with a clean, soft, dry cloth. If necessary,
first wipe the surface with a soft cloth slightly dampened with mild soapy water,
then with a fresh cloth dampened with clean water. Wipe dry immediately with
a dry cloth. NEVER use abrasive cleaners or a volatile cleaning agent, such
as benzene, thinner, or alcohol. Avoid spraying insecticide, waxes, polishing
agents, or any aerosol product near the unit.

WARNING: To prevent shock hazard, always make sure to turn the Master
Power switches off when using liquid near the amplifier.

When You Are Away

If you will not be using your home theater system for an extended period of
time, it is always a good idea to turn the unit off using the Power Switch on
the rear panel of the amplifier.

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 when thermal overload creates a condition
that could potentially cause damage to the unit or to your speakers, the Model
7900 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
7900 to make certain that none of the strands 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. Also, check the system to ensure the negative (–)
speaker outputs are not connected together and are not connected to ground.
Now 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 common prob-
lems in audio/video systems. Hum, which may be present even at low volume levels
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 connected 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.
