(1). PEAK LED INDICATOR
This LED indicators let you check the level of the signal input
to the channel. The peak indicator lights when the input signal
reaches 5dB below the channel’s clipping point. This indicator
show the level of the Post-EQ/ pre-fader signal. If the PEAK

and dynamic range will be achieved if you adjust the TRIM
control so that the peak indicator lights occasionally. This
control adjusts the channel’s mic input sensitivity between
-50dB and -6dB and the line input sensitivity between -30dB
and +14dB.
The mono/stereo combination input channel have a sensitivity
of +20dB to-20dB

on the top panel.
(9). OUTPUT LEVEL METER
A vertical row of ten LED show the continuous output level of
main Output L/R.
This type of display is free from over shoot problem of me-
chanical meters and is highly visible under poor lighting condi-
tions. The 0 LED means an output level of +4dB for +4dB
output (that’s the rated level).
(10). POWER INDICATOR
This indicator lights when the power switch is turned on.
(11). PHANTOM POWER SWITCH
This switch toggles phantom power on or off.If you set the switch
on, the mixer supplies power to all channels that provide XLR
mic input jacks. Set this switch on when using one or more
condenser microphones.

jacks.
Be sure to leave this switch off ( ) if you do not need
phantom power.
When pressed the switch on ( ), be sure that only con-
denser mics are connected to the XLR input jacks.
Note, however, that the switch may be left on without
problem when connecting to balanced dynamic
microphones.
To avoid damage to speakers, be sure to turn off

MIC JACKS
A 3-pin XLR-type connector is used for balanced low imped-
ance microphone inputs.(1: sleeve, 2: hot, 3:cold)
BALANCED LINE IN JACKS
A standard 1/4” phone jack is used for balanced or unbal-
anced line level signals. Examples of line level signals include
most electronic keyboards, synthesizers, turn-tables(with
appropriate pre-amps), tape decks and the line outputs from
other mixers.

(3). CHANNEL INPUT JACKS
These are unbalanced stereo line input jacks. Two jack types
are provided phone type and RCA pin type.
(4). RETURN L (MONO), R Jack
These are unbalanced 1/4” phone-type line input jacks. The
signal received by these jacks is sent to the MAIN bus and
AUX bus. These jacks are typically used to receive a return
signal from an external effect (reverb, delay, etc.)
NOTE:These jacks can also be used as an auxiliary stereo
input. If you connect to the L (MONO) jack only, the mixer
will recognize the signal as monaural and will propagate the
identical signal on both L and R jacks
(5). TAPE IN JACKS
These RCA pin jacks input a stereo sound source. Use these
jacks when you want to connect a CD or DAT directly to the
mixer for monitoring.
NOTE:You can adjust the signal level using the TAPE IN
control in MAIN control section.
(6). REC OUT JACKS
The REC OUT jacks send the pre-fader signal from the master
bus for recording by the tape deck.
(7). SEND JACKS
* AUX
These are unbalanced phone jacks-type output jack.
This jack output the signal form AUX bus, respectively.You use
this jack, for example, to connect to an effector or to a cue box
or other such monitoring system.
* EFX
These are unbalanced phone jacks-type output jack that output
the signal form the EFFECT bus.
You use this jack, for example, to connect to an external effector
