Master Mix
The XONE:464 provides two independent stereo mix outputs, Mix1
and Mix2. The mono channels can be routed to either or both
outputs. The stereo channels route to Mix1 only, either direct or
through the crossfader. However, Mix1 can be routed to Mix2 as the
music feed to the main music + mics mix if required.
Both outputs provide master fader control, inserts, metering, balanced
XLR main outputs, and RCA phono secondary outputs, ideal for
recording the performance. An additional mono output with both XLR
and TRS jack outputs can be assigned from either mix using a rear
panel switch. These are ideal for feeding a sub-bass, mono zone and
sound-to-light system. This unique output capability is able to satisfy
the most demanding audio system applications.
MIX1 METERS A pair of meter bars displays the post-master left
and right output levels of stereo Mix1. Each meter has 12 leds to
indicate signal levels from as low as –30dB. Green and yellow leds
indicate normal operating levels. The top red led lights at +16dB to
warn that you are within 5dB of clipping. Meter ‘0’ repr4dBu
at the main outputs. The meters are peak responding. This means
that they have a fast attack and are able to display fast transients
accurately. With the output masters at maximum you should adjust
the mix so that the signal averages ‘0’ on the meters with highest
peaks no more than ‘+6’. This still leaves plenty of mix headroom.
MONITOR / MIX2 METERS A pair of meter bars displays the level of
the selected monitor source or CUE. With all selector switches up
these default to display the post-master left and right output levels of
stereo Mix2.
MIX1 to MIX2 Routes the pre-master Mix1 signal to Mix2 to create a
stereo subgroup. For example, use Mix1 to feed the dance floor, Mix2
to feed the stage PA. Press the underpanel MIX1 to MIX2 switch to
route the music only dance mix to the stage PA. Note that the Mix1
master control does not affect the Mix1 level to Mix2. This is a
tamperproof underpanel switch to avoid accidental operation in
situations where Mix1 and 2 are used as independent outputs. It
should be selected using a pen or similar pointed object.
MASTER ROTARIES Mix1 and Mix2 each have a rotary master
control to adjust the output level. Each is a stereo rotary which
adjusts the left and right signals at the same time. The ‘10’ mark
indicates maximum level operating position. If you find yourself
normally setting the master control in the lower half of its travel then
the connected equipment may be too sensitive for the operating level
of the console. With the master control set to its ‘10’ position adjust
the input level trim of the connected equipment for the loudest output
required. Note that the insert points are pre-master. These can be
used to patch in compressors and limiters to protect the system from
excessive sound levels.
In a club or similar installation strict sound level and noise
regulations may apply. Check that your system levels are
correctly set up to comply.
