24. EFX Control
This control alters the signal level that is sent to the EFX send (AUX
3) output and the built-in digital effect processor. The EFX send
signal can be used in conjunction with external signal processors
(this signal of which can be returned to mixer via the AUX return
input), or simply as an additional auxiliary output.
25. 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).
26. On Button and Indicator
This turns the channel on, allowing the user
to use the feed from the channel’s inputs to
supply the MAIN L/R, GROUP 1/2, AUX and
EFX buses. The corresponding indicator will
be illuminated when turned on.
27. 1-2 and L-R Buttons
These handy buttons allow you to decide the
audio path of the corresponding channel.
Pushing the “1-2” button allows the signal to
be sent to the Group 1-2 mix, where the “L-R”
allows it to be sent to the Main L-R mix.
28. Peak Indicator
This LED indicator will illuminate 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.
29. Solo Button
The Solo button is pushed to allow the signal
of a corresponding channel to be sent to the
Control Room / Phones control (pre or post
fader, depending on the properties selected
by the pre / post button, located by the Control
Room / Phones control), for use with either
headphones or studio monitors. This also
allows easier setting of the input gain and
tracking of audio by sound engineers. The
corresponding green LED will illuminate when
the Solo button is engaged.
30. Channel Level Control (Fader)
This control will alter the signal level that is
sent from the corresponding channel to the main mixing bus.
31. +4 / -10 Buttons
These buttons, located on each stereo input channel, 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 dBV (consumer audio
standard), it is best to engage the switch, allowing the signal to be
heard. If the input source is +4 dBu (professional audio standard)
the corresponding input channel’s button should be disengaged to
ensure the integrity of the Mixer’s circuitry. If you are unsure of the
source’s operating level, we suggest leaving the switch disengaged
until you test the source’s signal. You can then engage if necessary
(if the level of input is obviously too low).
Digital Effect Engine
32. Digital Effect Display
This panel displays the titles of different effects that can be added
to audio. For a list of available effects and their related parameter
values, please observe the Digital Effect Table.
33. Program Control
This control is used to scroll through the various effects shown
on the Digital Effect Display. Turning the control will automatically
change the effect and apply it to the mix. To see the list of available
programs, please check the Digital Effect Table.
34. Peak Indicator
This LED indicator will illuminate when the device hits high
peaks, 6 dB before overload occurs. It is best to adjust the EFX
Return Fader so as to allow the Peak indicator to light up on
regular intervals only. This will ensure a greater dynamic range
for audio.
35. Effect On Button and Indicator
This button is pushed to turn the corresponding effect panel on or
off. When the effect processor is turned on it the corresponding
LED illuminates.
36. Parameter Control
This will adjust the appropriate parameter of the digital effect that
is applied to the audio feed. Please refer to the Digital Effects
Table for more information on Effect parameters.
NB.
The digital effect processor has a “memory” function, which allows you
to adjust the Parameters of a Program, then, if you change the Parameters
of another Program and return to the original one, your Parameter setting
will be kept until the Parameter control is turned once again, at which time
it will be altered according to the control.
