receiver or microphone.
3. Two XLR microphone inputs on rear. You can use
two XLR inputs to plug in mics, guitars, etc.
4. 3D sound processor. Advance digital sound enhancement technology improves the full range of
audio frequencies to fine-tune the sound of your
musical output. It enables users to enjoy a more
natural and comfortable sound.
Avoid Moisture, Water and Dust
5. Microphone treble and bass control. You can
adjust the level of high and low frequencies to the
microphone channels.
• Do not place the mixer in a moist environment
or in an area where there might be an excessive
amount of dust build up (e.g., near a fan).
6. Microphone echo control. You can adjust the
digital echo effect applied to the microphone
channels.
• If water or any liquid should get into the unit, turn
off the power and unplug the unit from the wall
outlet immediately. Consult your dealer or an authorized repair station. Using the unit in this state
may lead to fire or electrical shock.
7. Individual microphone volume control. Adjust
each microphone volume individually.
8. Multiplex. With Multiplex karaoke media, lead
vocals and music are recorded in separate left and
right stereo channels. You can select channels
with the Multiplex switch on the front panel to
cancel the guide vocals.
Avoid High Temperatures

set near any heating device.
Notes on Installation
9. Audio line in. The audio line in is for connecting the sound output of a computer, MP3 player,
MP4 player or DVD player to the KM-112 for
audio output.
• Select a place where the unit will be level, dry and
neither too cold nor hot.
• Do not use unit on its side or where it will be subject to vibrations (e.g., near speakers).
10. USB audio in and out. The USB port is for connecting the KM-112 to a computer via USB port
for both audio in and out. See page 4, “Recording
and Playback with Computer” for more information
on using USB.

• Do not leave heavy objects on top of unit.
Preventing Malfunctions of the Unit
• No parts in this unit are user-serviceable. If the
unit no longer functions, unplug the unit from
the wall outlet and contact your dealer for service
options.
11. One audio line out. This output is for connecting
the KM-112 to the input of an amplifier, receiver
or TV audio input.
12. Mini-jack audio out. This front panel jack can be
used to plug into your headphones or speakers for
listening or monitoring while recording through
the USB interface.
