33. +4 / -10 Buttons
These buttons, located on each stereo input channel, are
used adjust the input sensitivity of the corresponding chan-
nel, 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 en-
gage if necessary (if the
level of input is obviously
too low).
Digital Effect Engine
34. Digital Effect Display
This panel displays the titles of dif-
ferent 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.
35. 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.
36. 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.
37. 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.
38. 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.
39. 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 be-
tween 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 fl ash at the
intervals selected.
Master Section
40. AUX Return Controls
These controls adjust the signal level of audio fed through
to the stereo AUX Return inputs. The “To AUX 1” control
adjusts the pre-fader level of the signal from the AUX Re-
turn controls to the AUX mixing buses.
41. EFX Return Control
This control adjusts the signal level of audio fed through
to stereo AUX Return 3 inputs. If no device is plugged into
the AUX Return 3 inputs, this control then acts as the fi nal
level control of the built-in Digital Effect Engine.
42. Main L/R - Group 1/2 Button
This button changes the destination of the signal sent from
the AUX Return 3 mixing buses between the Main L/R and
Group 1/2 mixing buses.
