1.CHANNEL CONTROL SECTION
(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 GAIN 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 ad -
just 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). 3BAND EQUALIZER CONTROLS
This is a 3-band equalizer with center frequencies, range and
type as shown below. The frequency response is flat when the
knob is in the “ 0 ”position.
CONTROL MAX.
BOOST/CUT
FREQUENCY TYPE
HIGH ±15dB 12kHz Shelving
MID ±12dB 2.5kHz Peaking
LOW ±15dB 80Hz Shelving
(5). AUX 1 CONTROLS
This knobs control the level of the signals sent to AUX 1 bus.
This control is placed before the channel volume, it will be not
affected by the channel level volume.
(6). EFX CONTROLS
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 EFX bus signal is also fed into the internal
digital signal processor. Since this control is placed after the
channel fader, the signal level will be affected by the channel
(7). 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 L bus,turning it to the right
moves the source toward the MAIN R bus.
(8). CHANNEL LEVEL VOLUME
This is the channels main level control. It determines the
level of the signal that is sent from the channel to the master
mixing 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 volume should
be set at the minimum position to prevent the addition of
unwanted noise to the main program signal.

Points to Remember
Points to Remember
- 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 equipment 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 inter-
ference 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 independent ‘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.

Before connecting to microphones and instruments, be sure that all devices are turned off. Also be sure that all of the
mixer’s channel fader and master control faders are set all the way down.
For each connection, connect one end of the cable to the relevant microphone or instrument and connect the other end to
the appropriate input jack on the mixer.
NOTE: Where an input channel provides both a MIC INPUT jack and a LINE INPUT jack, you may use either one of these
