Radio Shack 32-2056 - Manual (Page 2)

Using Your Mixer
1 Set the POWER switch to ON. To avoid popping
sounds, always turn on the mixer before you turn on
your amplifier.
2. Turn on the output amplifier and set its volume to
minimum.
3. Set the audio input source’s volume to minimum. Turn
on the source, and set it to play (or continuously talk
into the microphone).
4. Adjust the mixer’s corresponding CHANNEL 1, 2, 3,
or 4 to level 6-10. When mixing more than one audio
input, adjust each input’s volume to about the same
listening level.
5. Adjust the output amplifier’s volume as desired.
6. When you are finished mixing, turn off the mixer, the
output amplifier, and all audio input sources.
Mixing Mono or Stereo
To mix mono signals with stereo signals, set STEREO/
MONO to STEREO.
When STEREO/MONO is set to MONO:
•
The mixer routes monaural input signals of devices
connected (separately) to the mixer’s AUX 1 L, AUX 1 R,
AUX 2 L, AUX 2 R jacks to both outputs.
• The mixer changes stereo input signals of devices connected
to the mixer’s AUX 1 L/R and AUX 2 L/R jacks to monaural
signals.
For mono amplifiers (found in some PA systems), it is best
to set MODE STEREO/MONO to MONO.
Voiceovers
Talk into a microphone to mix pre-recorded music or
sound from an audio input source with your voice.
1. Before talking, adjust CHANNEL (corresponding to
the connected audio source) to the desired volume
level.
2. As the music plays, talk or sing into the microphone.
Adjust the microphone and audio levels so you can
hear yourself over the music.
3. If you pause and stop talking or singing, adjust
CHANNEL to its original position (step 1).
4. When finished, adjust the microphone’s volume to
0 and the audio source’s CHANNEL to its original
position (step 1).

Power-Cord Protection — Route power-supply cords so
they are not likely to be walked on or pinched by items
placed on or against them, paying particular attention to
cords at plugs, convenience receptacles, and the point
where they exit from the appliance.
Power Lines — An outside antenna system should not
be located in the vicinity of overhead power lines or other
electric light or power circuits, or where it can fall into
such power lines or circuits. When installing an outside
antenna system, extreme care should be taken to keep from
touching such power lines or circuits as contact with them
might be fatal.
Nonuse Periods — The power cord of the appliance should
be unplugged from the outlet when the appliance is to be
