Troubleshooting
Using MONO/STEREO
When you set
MONO/STEREO
to
MONO
,
the mixer combines the left and right
channels then sends the signals to the
OUTPUT R
and
L
jacks. The combined
output signals can be used by a monau-
ral amplifier, such as a PA amplifier.
When you set
MONO/STEREO
to
STE-
REO
, the mixer keeps the left and right
stereo channels separated, then sends
the signals to the
OUTPUT R
or
L
jacks.
The stereo output signals can be used
by a stereo amplifier or tape deck.

Troubleshooting
Your mixer should require very little maintenance. If you have problems, refer to this
chart for possible solutions. If you cannot solve the problem, contact your local Ra-
dioShack store for assistance.
Problem
Solution
Nothing works.
Check the AC power connection. Make sure the AC outlet is “live.”
Check the power connections to the rest of the system (such as the
amplifier or receiver).
No signal from an
audio input source.
Check the control setting.
Check the connections between the mixer and the input source.
Hum from PHONO.
Connect the turntable's ground wire (usually black or green) to the
GND screw on the back of the mixer.
Hum from other
inputs.
Make sure there are no low-level inputs connected to CD 1 or CD 2.
Feedback “squeals.”
Move the microphone further away from the output speakers or use
a directional microphone.
