Main Amplifier Fuse

The Outlaw 7100 uses internal fuses to protect both the amplifier and your speak-
ers from damage. In the event that a fuse replacement is required, be certain that
a fuse of the original rating is used. If a fuse continues to fail, your unit may have
developed a fault. In this event, please contact us for assistance.

WARNING: Always turn the amplifier off and remove the power cord
from the source of AC Power before replacing the fuse.

Protection Mode

Under some conditions, such as a shorted speaker wire, DC voltage on an input
connection or thermal overload, the Outlaw 7100 will place itself in a protect
mode to prevent damage to the amplifier. When this happens the amplifier
will mute to protect both the amplifier and speakers from damage. Should this
occur, IMMEDIATELY turn the unit off, using the Power Switch, and disconnect
the AC power cord. Examine all speaker connections to make certain that there
are no shorts. Turn the unit back on. If the unit continues to go into the protect
mode, contact us for assistance.

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.
