32. +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
33. Digital Effect Display
This panel displays the titles of
different effects that can be added to
audio. When you select the effect, the
name will illuminate, and the alteration
be applied automatically. For a list of
available effects, please observe the
Digital Effect Table.
34. 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.
35. Peak Indicator
This LED indicator will illuminate when the device hits
high peaks. It is best to adjust the EFX Send Controls
(on all Input Channels and the Master Section) so as
to ensure the Peak indicator does not light up at all.
This will ensure a greater dynamic range for audio.
36. 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, the corresponding LED illuminates.
37. Parameter Control
This will adjust the one main parameter of the digital
effect program that is applied to the audio feed. Please
refer to the Digital Effects Table for more information
on Effect parameters.
NB.
The digital effect engine 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.
38. Tap Delay Button and Indicator
When the tap delay program is selected, this button
is used to determine the delay time. By pushing the
button several times, the effect engine interprets the
time between last two pushes and remembers this as
the delay time until the button is pushed again. When
the tap delay effect is selected, the corresponding
LED will flash at the intervals selected.
Master Section
39. AUX Return Control
This control adjusts the signal level of
audio fed through to the stereo AUX 1
Return input. Each AUX return control
also features a SOLO button, which sends
the signal to the Control Room / Phones
mixing bus, most commonly for monitoring
purposes. The accompanying “To AUX 1”
control allows users to adjust the volume of
that particular signal that is sent to the AUX
1 send mixing bus.
40. EFX Return Control
This 60mm fader adjusts the signal level of
audio fed through to stereo AUX Return 2
inputs. If no device is plugged into the AUX
Return 2 inputs, this control then acts as
the final level control of the built-in Digital
Effect Engine. The EFX Return Control
also features a SOLO button, which allows
users to send the signal to the Control
Room / Phones mixing bus. There is also
a 1-2 button, which sends the signal to the
Group 1 and 2 mixing bus, as well as a
L-R button, which sends the signal to the
Main L-R mixing bus. The accompanying
“To AUX 1” control allows users to adjust the volume
of that particular signal that is sent to the AUX 1
send mixing bus. An on button and indicator also
accompanies this control, allowing users to mute and
activate the channel at will.
