17. Middle Frequency Control
(MU802 and MU1002X)
This control is used to provide a
peaking style of boost and cut to the
level of middle frequency sounds
at a range of ±15 dB. Changing
middle frequencies of an audio
feed can be rather difficult when
used in a professional audio mix,
as it is usually more desirable to
cut middle frequency sounds rather
than boost them – soothing overly
harsh vocal and instrument sounds
in the audio. The middle frequency
control is featured on the MU802
and MU1002X. The MU502 features
High and Low Frequency controls on
channel 1 only.
18. 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.
19. EFX Control (MU802 and MU1002X)
These controls alter the signal level that is sent to the EFX SEND
output, which 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 auxiliary output for any means
required. On the MU1002X, this control is also used to alter the
signal level that is sent to the effects mix. This allows users to apply
one of the 16 built-in digital effects to it. This control is featured on
the MU802 and MU1002X only.
20. +4 / -10 Switch (MU1002X only)
This switch is used adjust the input sensitivity of the corresponding
channels, which will adapt the MU1002X to external devices which
may use different operating levels. If the input source is -10 dBV,
it is best to engage the switch,
allowing the signal to be heard.
The +4 dBu mode is suitable for
use with professional audio level
signals, which are considerably
higher than the consumer level.
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).
21. 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, this
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).
Each model features a PAN or BAL control on each of their
channel strips.
22. Peak Indicator
This LED indicator will illuminate when the channel hits high peaks,
6 dB before overload occurs. It is best to adjust the gain of the
channel so that the PEAK indicator lights up on intervals only. This
will ensure a greater dynamic range of audio. The Peak indicator
is on channel 1 only of the MU502 mixer, channels 1 and 2 of the
MU1002X and channels 1 through 4 on the MU802.

23. Level Control
This control will alter the signal level that is sent from the
corresponding channel to the main mixing bus. There are 3 level
controls in total, one on channel 1, another controlling the level of
channels 2 and 3, and a final one on channels 4 and 5.
Effect Processor
24. Effects On Button and Indicator (MU1002X only)
Pushing this button will turn the built-in effect processor on and
off. When the effect processor is activated, the corresponding LED
will light up to indicate so.
25. Peak Indicator (MU1002X only)
This LED indicator will illuminate when the EFX signal hits high
peaks, just before overload occurs. It is best to adjust the EFX
to Main control so as to ensure the Peak indicator does not light
up.
26. Program Control (MU1002X only)
This control will allow users to select one of the 16 built-in digital
effects of the MU1002X. The effect names that correspond with
the numbers can be found on the top of the MU1002X mixer's
face, or in the digital effect table.
27. Parameter Control (MU1002X only)
Turning this control will adjust the main parameter of the selected
effect; whether it is delay time, reverb time, etc. Each effect's
parameter can be found on the digital effect table.
28. Tap Delay Button and Indicator (MU1002X only)
Pushing this button twice when the tap delay effect (16) is selected
will set the delay time of the effect. Push the button repeatedly and
the time between the last two pushes will be calculated as your
tap delay time. The LED that accompanies this button will flash
at the selected intervals.
29. EFX To Main Control (MU1002X only)
This control adjusts the final level of the EFX mix (as taken from
the EFX level controls on each channel strip), the audio of which
is sent to the Main L-R mix (on the MU1002X only) and to the
EFX send output. It can also be sent to the Control Room/Phones
output, when the EFX Cue button is engaged.
