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 an 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 buttons, located on stereo channels,
are used adjust the input sensitivity of the
corresponding channel, which will adapt the
mixer to external devices which may use
different operating levels. If the input source is
-10 dBu (consumer audio standard), it is best
to engage the switch, allowing the signal to be heard. If the input
source is +4 dbV (professional audio standard) the corresponding
input channel's button should be disengaged. If you are unsure of
the source's operating level, leave the switch disengaged until you
test the source's signal.
