Operation

Important: Note the 

AUX LEVEL

 setting,

so each time you want to mix that
source you can set the control to the
correct setting. 

Notes:

• If it was necessary to set the 

AUX LEVEL

control to 

10

 to get a reading of up to 

0

on the VU meter, then set 

AUX LEVEL

 to

about 

8

 and adjust the 

AUX GAIN

 control

to get a reading of up to 

0

 on the VU

meters. (See “Using Gain” on Page 11.) 

• If the above does not work, set 

AUX

GAIN 

mid level and rotate 

MASTER

clockwise until you get a reading of 

0

 on

the VU meters. 

• Readjust 

MASTER

 affects the level of the

previously set input sources. You must
readjust those sources until you get a
reading of up to 

0

 on the VU meters for

each.

5. Stop playback of the selected input
source.

MIXING THE INPUTS 

You can connect input signals from up to 12
audio sources, select any two of the channel
input sources, then mix them so only one or
both play through your sound system. 

Mixing requires three operations:

• Playing one input source.

• Monitoring the next input source.

• Switching to the next input source.

You can start with either of the two selected
sources.

To prevent prematurely mixing audio sourc-
es, set all volume level controls to 

0

.

To avoid sudden and inaudible sound out-
puts from any audio devices that you con-
nect to the mixer, be sure to set their power
controls to off and any tone controls to flat.

Playing One Input Source 

1. Set 

ASSIGN

 

A

 to the desired source,

then set 

CROSS FADER

 to 

A

2. Select the mixer's input — 

CH 1

CH 2

,

CH 3

, or 

CH 4

3. Set the input selector control to the input

source you want to play first through
your sound system. 

4. Adjust the receiver's or amplifier's (not

the mixer's) volume control to the
desired volume. 

Make sure the first input source's vol-
ume level slide control is set to the cor-
rect preset position. 

5. Start playback of the input source. 

Monitoring a Second Input Source 

Monitoring a second input source's signal
level requires selecting the input source that
is not currently playing, finding the desired
section you want to mix, then adjusting the
source's sound level so it matches the vol-
ume level of the source currently playing. 

1. Connect and put on headphones. 

Note: You can listen to one channel
through the headphones while the other
channel is playing through the sound
system. 

2. Set 

ASSIGN B

 to the second input

source. 

3. Set 

CUE ASSIGN

 to the audio input

source (

CH 1

CH 2

CH 3

, or 

CH 4

) you

want to monitor.
