Operation

Note:  We recommend you not adjust the

GAIN

 controls after you have preset the in-

puts as some sound imbalance could occur. 

Setting the Sound Balance 

BALANCE

 lets you adjust the sound balance

between the left and right speakers. If your
speakers are properly positioned and your
listening area is centered between the
speakers, the center setting of the control is
usually the best. 

If the sound seems to be louder from one
speaker, adjust 

BALANCE

 until the sound

seems to be coming from a point midway be-
tween the speakers. 

USING A MICROPHONE 

Using an XLR Microphone 

To mix the microphone connected to the
XLR jack with other audio input sources, ad-
just 

DJ MIC LEVEL

 to increase or decrease

the microphone volume without affecting the
volume of the other inputs. 

Set 

DJ MIC LEVEL

 to 

0

 when you are not us-

ing the DJ microphone. Or, if the microphone
has an ON/OFF control, set it to OFF and
leave 

DJ MIC LEVEL

 at its preset position.

Using an AUX Microphone 

To mix a microphone connected to the 

AUX

MIC

 jack with other audio input sources, set

AUX MIC/LINE

 to 

MIC

. Adjust 

AUX LEVEL

 to

increase or decrease the microphone vol-
ume without affecting the volume of the other
inputs. 

When you are not using an 

AUX

 microphone,

set 

AUX MIC/LINE

 to 

LINE

. This lets you mix

the output from the device connected to 

AUX

LINE MONO

 jacks. 

Using TALKOVER 

To use the microphone and reduce other au-
dio inputs so the microphone can be heard
more clearly, set 

TALKOVER

 to 

ON

To turn off 

TALKOVER

, set T

ALKOVER

 to

OFF

. All the audio inputs including 

DJ MIC

and 

AUX MIC

 play at the same output level,

and the background music volume is not re-
duced. 

Using MUTE LEVEL 

To increase background music when using

TALKOVER

, rotate 

MUTE LEVEL

 toward 

MIN

.

To reduce background music, rotate it to-
ward 

MAX

.

Using PAN 

To play either microphone or the 

AUX LINE

output on the left or right channel, adjust the
appropriate 

PAN

 control. Set it to 

L

 to play

through the left channel, to 

R

 to play through

the right channel, or to any other position be-
tween 

L

 and 

R

 to play through both channels. 

USING SOUND EFFECTS 

There are six preprogrammed sound effects
for your mixing selection — a hi-hat close, a
rim shot, a cow bell, a cymbal, a bass drum,
and a laser drum. 

To play a sound effect, repeatedly press or
hold down the desired 

SOUND EFFECT

 but-

ton.

Rotate 

SOUND EFFECT LEVEL

 left or right to

increase and decrease the sound effect vol-
ume.

USING ECHO EFFECTS 

The mixer plays echo effects, and lets you
adjust the echo delay, the number of echo
repeats, and the echo's volume.
