example, near a bathtub, washbowl, kitchen sink,
in a wet basement, or near a swimming pool, or
the like.
3. This product, either alone or in combination with
an amplifier and headphones or speakers, may
be capable of producing sound levels that could
cause permanent hearing loss. Do not operate
for a long period of time at a high volume level or
at a level that is uncomfortable. If you experience
any hearing loss or ringing in the ears, you
should consult an audiologist.
4. The product should be located so that its location
or position does not interfere with its proper
ventilation.
5. The product should be located away from heat
sources such as radiators, heat registers, or
other products that produce heat.
6. The product should be connected to a power
supply only of the type described in the operating
instructions or as marked on the product.
7. Always turn the power off when the instrument
is not in use. The power-supply cord of the
product should be unplugged from the outlet
when left unused for a long period of time.
8. During an electrical storm, turn off the power
and unplug.
9. Care should be taken so that objects do not fall
and liquids are not spilled into the enclosure
through openings.
10. The product should be serviced by qualified
service personnel when:
A. The power-supply cord or the plug has been
damaged; or
B. Objects have fallen, or liquid has been spilled
into the product; or
C. The product has been exposed to rain; or
D. The product does not appear to operate
normally or exhibits a marked change in
performance; or
E. The product has been dropped, or the en¬
closure damaged.
11. Do not attempt to service the product beyond that
described in the user-maintenance instructions.
All other servicing should be referred to qualified
service personnel.

■ FEATURES
1. A compact 19" rack mount type keyboard mixer with 8 input
channels and 2 output channels.
2. Three-position (H/M/L) gain switches that permit mixing of the
different levels from keyboards, drum machines, guitars, and
vocals. (Channel 1 and 2 have a special microphone position.)
3. Two EFFECT loops, EFFECT1 and EFFECT2, for each channel.
4. PANPOT knob for each channel.
5. High signal-to-noise ratio (123 dB, IHF-A) to meet today's
highest recording requirements.
■ CONTROLS
(I) Front Panel
Make sure that the MASTER FADER controls 0 are at their minimum levels
before turning this switch on or off.
This LED lights when the power is on.
These three-position switches allow you to adjust the channel gain to match the
input level. The ones on channels 1 and 2 substitute a special microphone (MIC)
position for the highest gain.
These indicators warn when the input level exceeds the maximum. The gain
switches can be used to eliminate clipping.
These sliders control the volume for each channel. The normal position is "8".
These knobs control the amount of each channel's signal which is sent to the
EFFECT 1 mixing buss (Post-FADER).
These knobs control the amount of each channel's signal which is sent to the
EFFECT 2 mixing buss (Post-FADER).
These knobs control the stereo balance for each channel.
These sliders control the volume on the two output channels.
These meters monitor the final output levels.
This socket accepts a standard headphone jack.
This knob controls the volume of the headphone output.
This space is for affixing the gummed labels provided for indicating the sources for
each channel.
Note: Always use a lead pencil (grade "HB" or darker) or an oleaginous felt-tipped pen to write on the labels. To
rewrite on a label, erase your previous entry with a rubber eraser. (Never use an aqueous felt-tipped pen to
write on the labels.)
Note: Before applying the labels, wipe the area with a clean, dry cloth to remove any dirt or moisture.

■ IMPORTANT NOTES
• Always connect the mixer to the proper power supply,
• Use separate circuits for equipment that consumes a lot of power
or generates line noise.
• Protect the mixer from dust, heat, humidity, and direct sunlight.
• Turn all power switches off before connecting or disconnecting
equipment.
• Set the amplifier volume to its minimum setting before turning
on the mixer.
• Clean the mixer with a clean, dry cloth.
• Do not use benzene, paint thinner, or other solvents.

These PHONE jacks accept input from instruments and — for
channels 1 and 2 only — microphones.
This terminal sends out signals passed through from 0 EFFECT
1 VOLUME.
These terminals connect to the effector's OUT jacks. If the
effector's output is monaural, connect it to the L/MONO terminal.
This is an output terminal for 0 EFFECT 2 VOLUME.
These PHONE jacks accept output from the effector's OUT jacks.
These terminals send the mixer output to a power amplifier or
other equipment.
