Main Ampliﬁer Fuse

Your ampliﬁer uses internal fuses to protect both the ampliﬁer and your speakers

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, your ampliﬁer will place itself in a protect

mode to prevent damage to the ampliﬁer. When this happens it will mute to

protect both the itself and your speakers from damage. Should this occur, IM-

MEDIATELY 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.
