29. 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.
30. 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.
31. 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. This indicator also doubles as a Solo indicator,
when the Solo button is engaged.
32. 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 Peak indicator above the Solo button also
doubles as the Solo Indicator, illuminating when the Solo button
is pushed in.
33. Channel Level Control (Fader)
This control will alter the signal level that is sent from the
corresponding channel to the appropriate mixing buses (whether
they are the MAIN L/R or AUX).
34. +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).

35. Digital Effect Display
This 2-digital numeric display shows the program number that
is currently applied to your EFX audio signal. When you rotate
the Program control, you can scroll through different program
numbers; however the display will revert back to the original
program if a new program is not selected within a few seconds.
For a list of available effects, please observe the Digital Effect
Table.
36. Sig and Clip Indicators
Located within the Digital Effect Display are Clip and Sig LEDs.
The Sig LED will light up when any signal is received by the effect
processor, and the Clip LED will light up shortly before excessive
signals are dynamically clipped. If the Clip LED lights up too
often, it may be advisable to turn down the AUX /EFX master
control to ensure the signal level is not excessive.
37. Program Control
This control is used to scroll through the various effects. Turning
the control clockwise will allow users to ascend into higher
program numbers, and turning it counter-clockwise will allow
users to descend into lower program numbers. When turning to
a new program, a small LED will flash until you push the program
knob down – this will apply the effect. When a tap-delay effect
is selected, pressing this control will allow users to select the
tap-delay time.
By pushing the button several times, the effect processor
interprets the time between last two pushes and remembers this
as the delay time – until the button is pushed again. This is kept
even after the power is turned off. When the tap delay effect is
selected, a small LED (located between the two digit display)
will flash within the digital effect display window at the selected
intervals.
38. Effect Bypass
Use it to bypass the effects and monitor your audio before and
after the effect is applied. When the effect engine is bypassed,
the 2 small indicators on the digital effect display will flash.
