CONTROLS AND SETTINGS
Channel Controls
14. Line/Mic Gain Control
This controls the sensitivity of the input signal of the
Line/Microphone input. The gain should be adjusted to
a level that allows the maximum use of the audio, while
still maintaining the quality of the feed. This can be ac-
complished by adjusting it to a level
that will allow the peak indicator oc-
casionally illuminate. The MU 502
features a single gain control for
channel 1, located on the face of
the mixer, whereas the MU 802 and
1002 feature a gain control on both
channels 1 and 2, however located
directly below the Line inputs.
15. High Frequency Control
This control is used to give a shelving boost or cut of ±15
dB to high frequency (12 kHz) sounds. This will adjust
the amount of treble included in the audio of the channel,
adding strength and crispness to sounds such as guitars,
cymbals, and synthesizers.
16. Middle Frequency Control (MU 802 and 1002)
This control is used to provide a peaking style of boost
and cut to the level of middle frequency (2.5 kHz) 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 MU 802 and 1002. The MU 502 features High and
Low Frequency controls on channel 1 only.
17. 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.
18. High-Pass Filter (75 Hz) (MU 502 and 1002)
This button will activate a high-pass filter that reduces all
frequencies below 75 Hz at 18 dB per Octave, helping to
remove any unwanted ground noise or stage rumble.
19. EFX Control (MU 802 and 1002)
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 any stereo
input channel), or simply as an auxiliary output for any
means required. This control is post fader, therefore any
changes made to the corrsponding channel fader are also
applied to the EFX signal. This control is featured on the
MU 802 and 1002, however not on the 502.
20. +4 / -10 Switch (MU 1002)
This switch is used adjust the
input sensitivity of the corre-
sponding channels, which will
adapt the MU 1002 to external
devices which may use differ-
ent operating levels. If the input
source is -10 dBV (consumer
audio level), it is best to engage the switch, allowing
the signal to be heard. The +4 dBu mode is suitable for
Profesional Audio signals, which are considerably higher
than the consumer level. However, 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 the input signal
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 accord-
ingly (balance). Every model
features a PAN or BAL con-
trol on each of their channel
strips.
