3 MIC/RTN switch. MIC/RETURN Channels 1
and 2 are the 'MIC' channels. They can select
either the XLR microphone input or the alternative
jack stereo line return input. In the up position MIC
is selected, indicated by the green led. When
pressed, RTN is selected, indicated by the led
changing colour to red.
4 LEVEL control. Adjusts the input sensitivity of
the channel to match the connected source to the
console 0dB operating level. This provides a 35-
37dB range with continuous adjustment for line level
signals from –15dBu to +20dBu, –47dBu to –10dBu
for mics, or to match a wide range of RIAA turntable
cartridges. Use the Cue system to correctly set the
level.
Reduce LEVEL if the red PK! led flashes.
5 MIC EQ. The MIC/RETURN channel 1 and 2
equaliser provides a powerful tool to adjust the tonal
quality of the sound to correct source problems such
as microphone characteristics, proximity effect,
noise and feedback, or to adjust the overall 'feel'.
Start with the EQ controls set to their mid (flat)
position. Then adjust to achieve the desired sound.
Take time to experiment with these controls.
The XONE:92 equaliser provides separate tone
control over four frequency bands. The frequencies
in each band may be boosted or cut by up to 15dB.
The centre flat position is detented for quick
resetting.
HI Turn this control clockwise to boost and
anticlockwise to cut the high (treble) frequencies.
This has a shelving response with all frequencies
above the 10kHz turning point affected. Note that
frequencies below 10kHz are affected by a
decreasing amount. Use HI boost to brighten up the
sound by adding sparkle, and cut to reduce source
hiss and ambient high frequency pickup, or to limit
or lift the high response of vocal mics.
MID 1 Turn clockwise to boost and anticlockwise to
cut the higher mid frequencies. This has a bell
shaped peak/dip response that has maximum effect
at 2.5kHz. Boosting can enhance the intelligibility of
vocals. On the other hand, some situations may
require cutting to notch out a ringing frequency so
increasing gain before feedback.

MID 2 This is similar to MID 1 but affects the lower
mid frequencies centred at 250Hz. Boosting can
enhance the warmth of the sound while cutting can
reduce the unpleasant resonant or boomy effects.
LO This is similar to the shelving HI control but
affects the low (bass) frequencies below the 100Hz
turning point. Note that frequencies above 100Hz
are affected but by a decreasing amount. Use LO
boost to enhance low end punch, or cut to reduce
source hum and rumble, or to remove the bassy
sound of vocal mic proximity effect.
6 CUE switch. Press this switch to listen to the
pre-fader channel signal in the headphones and to
display its signal on the main meters. This does not
affect the house mix or booth speakers and lets you
audition the signal to check it before adding it to the
mix. Cue is post-EQ for MIC/RTN channels so that
you can check the effect of adjusting the EQ. The
switch illuminates when pressed so that you can
see at a glance which channel is cued.
7 DUCK / ON switch. For MIC/RETURN
channels 1 and 2 use this to introduce the MIC/RTN
signal to the mix outputs. Pushing the switch
upwards (non-latching) 'DUCK' will add the channel
input to the mix outputs until released and will
simultaneously duck the stereo music channels by
15dB. Pushing the switch down (latching) 'ON'
adds the channel input to the mix outputs without
ducking the stereo channels. The central, default
position is 'OFF' where the Mic channel inputs are
not added to the mix outputs.
8 ON / PK! LED. A dual-colour led
simultaneously displays which MIC/RTN channel is
switched ON, and warns of channel signal peaks.
The led lights green to indicate that a channel is
turned ON. Reduce the gain if the led PK! flashes
red.
9 Channel fader. A 60mm stereo fader adjusts
the signal level from off to unity at the top of its
travel. This allows smooth fade ins and a visual
indication of its contribution to the mix. The fader
does not affect the pre-fade Aux sends.
