18. Compressor Control and Indicator
This controls the onboard compressor function on channel
1. Turning this control up towards the 12 o'clock position will
adjust the threshold and ratio of the compressor at varying
degrees. Once you reach the 12 o'clock position, the
control will then adjust the compression settings along with
an onboard expander (or, in other words, a compander).
The LED that accompanies this control will light up when
the compressor is triggered.
19. TREBLE (High Frequency) Control
This control is used to give a shelving boost or cut of ±15
dB to high frequency (12 KHz) sounds. This will adjust
the amount of treble included in the audio of the channel,
adding strength and crispness to sounds such as guitars,
cymbals and synthesizers.
20. MID (Middle Frequency) Control
This control is used to provide a peaking style of boost and
cut to the level of middle frequency sounds (2.5 KHz) at a
range of ±15 dB. Changing middle frequencies of an audio
feed can be rather difficult when used in a professional
audio mix, as it is usually more desirable to cut middle
frequency sounds rather than boost them, soothing overly
harsh vocal and instrument sounds in the audio.
21. BASS (Low Frequency) Control
This control is used to give a shelving boost or cut of ±15
dB to low frequency (80 Hz) sounds. This will adjust the
amount of bass included in the audio of the channel, and
bring more warmth and punch to drums and bass guitars.

22. EFX Control
This control alters the signal level that is sent to the EFX
output, which can be used in conjunction with external
signal processors (this signal of which can be returned to
mixer via the stereo return inputs), or simply as additional
auxiliary outputs for any means required. This control also
adjusts the level of audio that is sent to the built-in digital
effect panel.
23. Pan / Balance Controls
This alternates the degree or level of audio that the left
and right side of the main mix should receive. On mono
channels, the PAN control will adjust the level that the
left and right should receive (pan), where as on a stereo
channel, adjusting the BAL control will attenuate the left or
right audio signals accordingly (balance).
24. Peak & Signal Indicators
These LEDs will light up when signals reach certain levels.
The Signal LED on the right will light up when any audio
signal is present on the channel. The indicator on the left
(Peak) will light up when the channel hits high peaks, 6 dB
before overload occurs.
It is best to adjust the channel level control so as to allow
the Peak indicator to light up on regular intervals only. This
will ensure a greater dynamic range of audio.
25. Channel Level Control
This control will alter the signal level that is sent from the
corresponding channel to the main mix.
26. +4 / -10 Buttons
These
stereo
adjust the input sensitivity of
18
the
which will adapt the mixer to
external
on their operating levels. If the input source is -10 dBu
19
(consumer audio standard), it is best to engage the switch,
giving the signal a slight boost. If the input source is +4
dbV (professional audio standard) the button should be
20
disengaged. If you are unsure of the source's operating
level, leave the switch disengaged until you test the
source's signal level.
