Setting Up Your Mixer
Installing Batteries
1. Remove the battery cover.
2. Insert one 9V battery (not
supplied) in the battery
compartment matching
the polarity symbols (+ and
–) marked on the back of the
battery cover.
3. Replace the battery cover.

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.
Notes:
• 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.
Presetting the 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.
Presetting Audio Devices
Make sure you power off the devices before you connect
them to the mixer.
To avoid sudden sound outputs from connected audio
devices, adjust the volume of the connected audio device
to its lowest level.
DC 9V
MONO/STEREO
Connections
Use shielded audio cables (not supplied) for all input
connections. The connected input source’s signals are
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)
on the mixer.
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.
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.
Four microphones
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.
Output
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.
