DSP3-150 AMPLIFIER
INSTALLATION USER MANUAL
7
If you have a problem, try isolating it first. For example, if you’re playing a DVD
and there is no sound, try replacing the DVD with an MP3 player to see if you get
sound. If it does work, then the problem is with the television, DVD player, or the
cables connecting them. If it doesn’t work, the problem will be with the amplifier,
speakers, or those cables.
Troubleshooting
Problem
Possible Cause
No Sound
The volume may be turned down or muted. Check the volume
settings on both the amplifier and the television/computer/CD
player/etc.
No Sound
Make sure the proper source is selected on the amplifier or re-
ceiver.
No Sound
Check the cord connecting the amplifier with the source. The
cord may be damaged or plugged into the wrong input or out-
put.
No Sound
Check the wires connecting the amplifier with the speakers.
Make sure they’re connected properly and not damaged in any
way.
Poor Sound
Quality
If you hear something like static, or the sound is cutting in and
out, check the audio cables. If the problem increases when a
cable is being moved, then the cable is most likely faulty or not
connected properly.
Poor Sound
Quality
Today’s audio systems may have several places to adjust the
volume, for example your MP3 player may have a volume con-
trol, and your amplifier may also have one. Check to be certain
that the volume isn’t turned up past 80% on any device.
Poor Sound
Quality
Try changing sources to be certain that the selection you’ve
chosen is a good quality recording.
