routed to the corresponding channel on the mixer.
Two stereo inputs
Connect the line level outputs from one device to the
mixer’s AUX 1 INPUT R and L jacks. Connect the line level
outputs from the second device to the mixer’s AUX 2
INPUT R and L jacks.
Four stereo sources as monaural inputs
Use shielded Y-adapters (not supplied) at each source’s left
and right outputs, and connect a separate stereo source to
each input jack (AUX 1 R, AUX 1 L, AUX 2 R, or AUX 2 L)

Battery Notes
•
Dispose of old batteries promptly and properly.
Do not burn or bury batteries.
Use only a fresh battery of the required size and recommended
type.
If you do not plan to use the mixer for more than a week,
remove the battery. It can leak chemicals that can damage
electronic parts.
Using AC Power
Connect a 9V AC adapter (not
supplied) to the DC 9V jack.
Connect the other end to the
power source.
Always connect the AC adapter to the mixer before you
connect it to AC power. When you finish, disconnect the
adapter from AC power before you disconnect it from the
mixer.
Using an adapter that does not meet the specifications could
damage the mixer or adapter.
Two monaural sources as stereo inputs
Use shielded Y-adapters (not supplied) at each source’s
monaural outputs, and connect one source to AUX 1 R and L.
Connect the other source to AUX 2 R and L.
Presetting the Mixer
Replace the battery when BATTERY LOW indicator lights.

•
Four monaural inputs
Connect each monaural device to each input jack (AUX 1 R,
AUX 1 L, AUX 2 R, or AUX 2 L) on the mixer.
Setting Up Your Mixer
To prevent accidental audio mixing or channel overdrive,
set MONO/STEREO to MONO, set POWER ON/OFF to
OFF, and slide Channel 1–4 to 0 (minimum) before you
connect to your power supply.
A sudden high output from the mixer could damage audio
devices connected to the mixer and could damage your
hearing, especially if you use headphones.
Four microphones
MIC jacks
Connect up to four microphones to the mixer’s MIC jacks
(1–4). Each microphone signal is routed to the mixer’s
corresponding channel.
If you connect an audio device and a microphone so they
are output to the same channel, the signals from both
devices are mixed and controlled by the mixer.
Presetting Audio Devices
Output
Make sure you power off the devices before you connect
them to the mixer.
To play the mixer’s output through your speaker system (at
parties, dances, conferences, etc.), use an audio patch cord
(not supplied) to connect the mixer’s OUTPUT L and R jacks
to your receiver or amplifier’s line input jacks.
To record the mixer’s output, use an audio patch cord (not
supplied) to connect the mixer’s OUTPUT L and R jacks to
your recording device’s line input jacks.
To avoid sudden sound outputs from connected audio
devices, adjust the volume of the connected audio device
to its lowest level.

Using Your Mixer
Important Safety Instructions
1
Set the POWER switch to ON. To avoid popping
sounds, always turn on the mixer before you turn on
your amplifier.
Read Instructions — All safety and operating instructions
should be read before the appliance is operated.
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).
