PRESETTING THE 
CONTROLS

Warning: A sudden high output from the
mixer could damage your hearing, especially
if you use headphones, and might also dam-
age the audio devices connected to the mix-
er's output. Before using the mixer, make
sure you set your receiver/amplifier's volume
control to its minimum volume level setting. 

Before you connect the power cord, make
sure you set 

POWER

 to off. To avoid sudden

and inaudible sound outputs from any audio
devices that you connect to the mixer, be
sure to have their power controls set to off,
and any tone controls set to flat. 

CONNECTING THE 
OUTPUTS 

To play the mixer's output signal through
your sound system (for events such as par-
ties, dances, conferences, and so on), con-
nect one end of an audio patch cord (not
supplied) to the mixer's 

OUTPUT AMP L

(white) and 

R

 (red) jacks, then connect the

other end to your receiver/amplifier's left and
right input jacks, matching left to left, and
right to right. 

To record the mixer's output signal, connect
one end of an audio patch cord (not sup-
plied) to the mixer's 

OUTPUT REC L

 (white)

and 

R

 (red) jacks, then connect the other end

to your tape deck's left and right line input
jacks, matching left to left, and right to right.

CONNECTING INPUTS 

You can connect up to ten audio input sourc-
es (such as cassette tape decks, CD players,
tuners, two magnetic-cartridge turntables, a
camcorder or a VCR) to the mixer’s input
jacks on the back panel. You can also con-
nect microphones to the appropriate jacks on
the top and back panels. 

1. Connect the line-level outputs from up to

six audio sources to the 

LINE 1

LINE2

,

LINE 3

LINE 4

LINE 5

, and 

LINE 6 

input

jacks, matching left to left, and right to
right.

Caution: Do not connect an audio
source with a line-level output to the
low-level 

PHONO 1

PHONO 2

, or 

AUX

MIC

 audio input jacks.

2. Connect the low-level outputs from up to

two audio sources (such as magnetic
cartridge turntables) to the 

PHONO 1 

and

PHONO 2

 input jacks, matching left to

left, and right to right. 

Note:

 

If you connect magnetic cartridge

turntables, connect their ground wires
(usually black or green) to 

GND

3. Connect a sound effect device (such as

an echo reverb or a digital sampler pro-
cessor) to the 

EFFECT SEND 

(output)

and 

EFFECT RECEIVE

 (input) jacks,

matching left to left, and right to right. 

4. Connect a mono input source (such as a

wireless microphone receiver) to the

AUX LINE MONO

 

jacks, matching left to

left, and right to right.
