GUARANTEED FOR LIFE

MultiMixer™10 is an extremely low noise, professional
quality, 10 channel stereo line mixer. The 6 panable inputs
(1 through 6) enable you to place a sound source any-
where in the stereo field. 2 of the 6 inputs (1 and 2) can
have their gain set for either line level or microphone use.
4 more channels (7, 8, 9 and 10) are unity gain inputs for
which there are no volume or pan controls. These channels
have to be controlled “at the source,” so they are ideal for
use as returns or AV ins. MultiMixer 10 comes with an
external 9 volt, 300 milliamp ac power adaptor. This adap-
tor should be plugged into a standard wall socket and
then into the MultiMixer’s back power jack. When this is
done the MultiMixer power LED will light. MultiMixer
will not work unless power is plugged in.
Multimedia Mixing. Many multimedia applications use
multiple sound sources. In a typical multimedia application
you might plug the MultiMixer in as follows: 1.) plug your
microphones into inputs 1 and 2 making sure that the gain
switches (on the side of the unit) are switched “up” to the
mic setting; 2.) connect the stereo output from your comput-
er soundcard to MultiMixer inputs 3 and 4; 3.) connect out-
puts from your MIDI tone module to inputs 5 and 6; and 4.)
connect the stereo audio output from a CD-ROM to unity
gain stereo input 9/10. Now, you can use the MultiMixer
pan pots to position the sounds of channels 1 through 6
wherever you want them.

Tips. If you set the MultiMixer's gains too high for a
given input, you may encounter distortion or signal clip-
ping (red clipping LED stays solidly lit). This will surely
happen if you plug in a synthesizer with its channel gain
set to full volume and also set MultiMixer left and right
master level pots to full. If you hear any distortion try
reducing the keyboard output level. Your MultiMixer
should always sound clean and noise free.
MultiMixer 10 Description:
•Front – Headphones. 1/8” stereo jack. Plug your head-
phones in here. If you are using phones with a 1/4” jack
you will need an adaptor. You can also use the head-
phone jack as an auxiliary output.
•Top – 1-6 Gain. Adjustable gain levels for each individ-
ual input. These are true gain controls, not volume pots.
What this means is that the MultiMixer never amplifies
the signal more than necessary so the noise level is always
as low as possible (of course, if your sound source is noisy
the output will be too). The center detent position is
roughly unity gain. (Remember, the overall gain of chan-
nels 1 and 2 is set using the dip switches on the left side of
the MultiMixer)
• Top – 1-6 Pan. Controls where in the stereo image the
sound will appear. Adjustable from all the way left to all
the way right. The center detent position is equal mix
right and left.
•Top – Master Levels (Left and Right). Control the over
all left and right output levels. These pots also control
the level of the headphone output.
•Top – Power LED. Shows when MultiMixer6 is on.

•Top – Signal Level LED. Shows when any audio signal
is coming into the MultiMixer.
•Top – Clip LED. Shows when the internal main ampli-
fiers inside of the MultiMixer are clipping. It is accept-
able to see these LEDs light occasionally, but if they are
solidly lit you should find the individual signal that is
too hot and turn it down.
• Back – Inputs 1 and 2. 1/4” mono phone jacks. These
two inputs may be set to either mic or line level using
the gain dip switches on the left side of the unit. Tip: if
you are using MultiMixer with an XLR microphone you
will have to get an XLR to 1/4” adaptor.
•Back – Inputs 3 through 6. RCA mono jacks. These are
line level mono inputs.
•Back – Inputs 7/8 and 9/10 (Stereo). 1/8” stereo mini-
jacks. These are line level unity gain stereo inputs. They
may be used as returns or AV/multimedia ins. Tip: since
the gain and balance of these inputs are fixed you must be
able to control these signals at their source.
•Back – Main Outputs (L, R). RCA jacks. These are the
main MultiMixer left and right line level outputs. They
should go to either a power amplifier or powered speak-
er inputs.
• Back – Main Output (Stereo). 1/8” stereo jack. Same
as the Main L and R outputs above except on stereo jack.
•Back – 9v ac power. The jack into which you plug a 9v
300 milliamp ac power adapter. Important: MultiMixer
will not work unless it receives power at this jack.
•Side – Gain Dip Switches. These two dip switches
independently control the gain of channels 1 and 2. In
the up position the gain is set for microphones and in
the down position for line level signals.
