Console Monitor System
The XONE:464 provides extensive console monitoring facilities.
Every signal can be checked individually or within any mix. Two
systems are provided, headphones and local monitor. The local
monitor typically feeds the DJ booth speaker system. The Cue
system lets you quickly check channel signals, correctly set the gain,
and cue tracks ready to bring into the mix. Facilities such as Mono
and Split-Cue switching are well suited to the way the professional DJ
works.
HEADPHONES 1 OUTPUT Two outputs are available for stereo
headphones, one on the front panel, the other on the rear panel. The
same signal is available from both. Headphones are available in
many different styles, impedances and volume ratings. To get the
best from your system we recommend that you use high quality
closed-ear headphones in the range 30 to 600 ohms. 8 Ohm
headphones are not recommended.
WARNING Some headphones are more sensitive than
others and can produce higher output levels. To avoid damage
to your hearing start with the PHONES level control at minimum
and turn up only as much as is needed to maintain comfortable
listening level. Do not drive headphones at high listening levels
for long periods of time.
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-fader left and right output levels of
stereo Mix2. When SPLIT CUE is selected the left meter displays the
active CUE signal, the right displays PRG (program), the switch bank
source in mono.
Each meter has 12 leds to indicate signal levels from a low –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 XLR outputs. The meters are peak
responding. This means that they have a fast attack and are able to
display fast transients accurately.
CUE A large red led lights when a channel CUE is active. This
indicates that the selected channel CUE signal is heard in the
headphones and displayed on the monitor meters. CUE also
overrides the local monitor if CUE ENABLE has been selected.
It is important to use CUE to set the channel gains correctly to
maintain the wide dynamic range achievable with this console. You
should adjust the channel gain so that the signal averages ‘0’ on the
monitor meters with highest peaks no more than ‘+6’. Reduce the
gain if the red PK leds flash.
HEADPHONES LEVEL Adjusts the level of the signal in the stereo
headphones. This does not affect the level of the local monitor. Read
the warning printed above regarding loud listening levels.
