Front Panels Controls
(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 indicator lights more
than briefly on high-level transients, you should use
the TRIM control to decrease the input sensitivity of the
channel. If this dose not work, reduce the output level
of the connected source.
(2). TRIM CONTROL
According to the level of the input signal, use this knob
to adjust the input to an appropriate level. The best
balance of S/N 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
(3). HPF(High-Pass Filter)
This switch toggles the HPF on or off. To turn the HPF
on, press the switch In ( ). The HPF cut frequencies
below 75Hz
(4). EQUALIZER
MONO CHANNEL
This 3-band equalizer adjusts the channel’s high, mid
and low frequency bands. Setting the knob to the “0”
position produces a flat frequency response .Turning
the knob to the right boosts the corresponding frequen-
cy band ,while turning to the left cuts the band. The
following tables shows the EQ type, base frequency ,
and maximum cut/boost for each of the three bands.

This indicator lights when the PFL switch is turned on.
(11). PFL SWITCH
When these switch is depressed, the channel input
signal can be routed to the PFL bus.
This switch allows you to monitor the pre-fader chan-
nel input signal through headphone outputs and
control room outputs.
(12).ASSIGN SWITCHES
Use these switches to send the channel’s signal to the
Group1-2 , Group 3-4 and/or MAIN L/R buses. Setting
the switch on ( ) causes the signal to be sent to the
corresponding group buses.
(13). CHANNEL FADER
This is the channel’s main level control. It determines
the level of the signal that is sent from the channel to
the master mixing, group outs and effect buses. It is
the settings of the input channel faders that determine
the mix, or the balance of sound levels between the
instruments or other sources connected to the inputs.
When a channel is not being used, its fader should be
set at the minimum position to prevent the addition of
unwanted noise to the main program signal.
(5). AUX 1 AND AUX 2 CONTROLS
This AUX1 knob controls the signal level that the chan-
nel sends to the AUX1 bus; the AUX2 knob controls
the signal level to the AUX2 bus.
If you are using stereo channels , the signals from the
L and R channels are mixed and send to the AUX1 and
AUX2 buses.
These controls are placed before the channel fader ,so
they control the AUX outputs regardless of the setting
of the channel fader.
(6). PRE/POST SWITCH
This button determines whether the AUX2 signal is Pre
or Post fader. Pre means not affected by the position
of the channel fader. Post means is affected by the
position of the channel fader.
Note that switch applies to AUX2 only. The signal to
the AUX1 bus always passes through the channel
fader first
(7). EFX CONTROL.
This knobs control the level of the signals sent to EFX
bus. The channel signals mixed by this bus have their
overall level set by the EFX SEND Control to the EFX
SEND jack on the front panel. The EFFECT bus signal
is also fed into the internal digital signal processor
(100PRESET DSP).
Since this control is placed after the channel fader,
the signal level will be affected by the channel fader’s
setting.
(8). PAN /BAL CONTROL
PAN (Mono Channel)
This control pans the channel signal across the master
L and R buses, thus determining the perceived position
of the sound from that channel in the output stereo
sound field. If a PAN control is set all the way to the
left,for example, the sound from that channel will be
heard from the left speaker system only.
If it is set all the way to the right, the sound will be
heard from the right speaker system only.
Intermediate settings will cause the sound to appear at
corresponding locations in the stereo sound field.
BALANCE (Stereo Channel)
This control adjusts the balance or the L/R position of
the stereo input signal.
Turning the BALANCE control to the left of center
moves the apparent source toward the MAIN MIX L
bus, turning it to the right moves the source toward the
MAIN MIX R bus.
(9). MUTE SWITCH
Set this switch on by pressing it in ( ), you will cut
off all of its signal feed into the MIAN L/R GROUP1-
2/3-4,AUX2(POST),EFX buses. The switch lights up
orange to indicate that it is on.

(1). CHANNEL INPUT JACKS
MIC JACKS
These are balanced XLR-type input jacks.(1: Sleeve,
2: Hot, 3:Cold)
BALANCED LINE IN JACKS
A standard 1/4” TRS phone jack is used for balanced
or unbalanced line level signals. Examples of line level
signals include most electronic keyboards, synthesiz-
ers, turn-tables (with appropriate pre-amps), tape
decks and the line outputs from other mixers.
(2). CHANNEL INSERT I/O JACK
These are input/output jacks located between the
head-amplifier and the high pass filter.
These jacks can be used to independently connect
these channels to devices such as graphic equalizers,
compressors, and noise filters. These are 1/4” TRS
(tip, ring, sleeve) phone jacks that support bi-direc-
tional operation.
NOTE:Connection to an INSERT I/O jack requires a
special separately-sold insertion cable such as illus-
trated below.
Tip:Output(Send to external device)
Sleeve:Ground
Ring:Input(Return from external device)
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
1.Where a channel provides a phone jack
and an RCA pin jack, you may use either one
of these jacks but you may not use both at
the same time. Please connect to only one of
these jacks on each channel.
2.The phone type jacks for CH9/10and11/12
also support monaural input. Specifically, if
you input only into the L(MONO) jack of either
pair (while leaving the R jack empty), the mixer
will propagate the same signal through both
L(MONO) and R inputs.

- In all cases, use good quality twin screened audio cable. Check for instability at the output.
- Always connect both conductors at both ends, and ensure that the screen is only connected at one end.
- Do not disconnect the mains earth from each piece of equipment. This is needed to provided both safety
and screen returns to the system star point.
- Equipment which has balanced inputs and outputs may need to be electrically isolated from the equip-
ment rack and/or other equipment, to avoid earth loops.
It is important to remember that all equipment which is connected to the mains it a potential source of hum
and interference and may radiate both electrostatic or electromagnetic radiation. In addition, the mains will
also act as a carrier for many forms of RF interference generated by electric motors, air-conditioning units,
thyristor light dimmers etc. Unless the earth system is clean, all attempts to improve hum noise levels will
be futile. In extreme cases there will be no alternative but to provide a completely separate and independ-
ent ‘technical earth’ to replace the incoming ‘noisy earth’. However, always consult your local electricity
supply authority to ensure that safety regulations are not being infringed.
