Aux Sends
At the top of each channel strip there are volume
controls for each of the stereo auxiliary sends. These
can be set to send the signal regardless of the
channel volume fader level, cross-fader and filter
controls. However, the EQ has an effect over the
auxiliary send regardless of the pre switch. Below
that is the phono and line switch. The gain on the
main channels has a notch in the centre position,
almost urging you to set it at that volume. However, it
seems to provide the perfect signal at its lowest
setting to achieve an average of 0dB. The mic/return
channels simply have the equivalent to a volume
control on a knob
Equalisation
All channels have four-band EQ for Hi, Mid 1, Mid 2
and Lo. On the main channels these all have a
maximum gain of 6dB, which will again please the
installers worried about their precious rig. The DJs
will be happy to see total kills, but only on the Hi and
Lo’s – the two Mids have a drop of -30dB. The actual
separation of the frequencies is much better than on
previous Xone mixers and the extra Mid to the norm
really helps smooth some awkward mixes out.
The EQ on the mic/return channels can be increased
or decreased by 15dB. This gives greater control over
voice and effects which usually require slightly more
attention than vinyl or CD and can also be used to
alter the sound more radically as part of a
performance.
There’s a wide Q (frequency width) for cut and a
narrow Q for boosting, which prevents accumulated
gain. Needless to say they sound great, but it’s a
shame there isn’t the ability to punch the EQ on and
off as on the 62.
Talkover
There’s a switch below the EQ on the mic/return
channels which activates the talkover function; again
this is a three position switch. In the middle the
sound is off, flick it towards you and the channel is on
full. Push the switch back and the channel is on but
the main mix is brought down by 20dB. This enables
perfect control and use of external effects to get a
really pronounced sound above the dry signal. It can
also be used for mic talkover, but there is no
reduction gain control and it’s not automatic, ie. as
the volume of the return or mic changes it does not
automatically reduce the main mix at those times.
Finally, the switch flicks back to the middle position
when released.
Faders
All the faders are incredibly tough while remaining
wonderfully smooth in operation and have new
slimmer knobs attached. The cross-fader has been
upgraded from the 62 with the addition of curve
control. This allows everything from a long, smooth
mix to a very sharp curve for chopping in and
scratching, a facility many DJs had complained was
lacking on previous models. There’s about a 2mm lag
before the sound kicks in on the sharpest setting, but
the action is intuitive and precise.
Channel Assign
There are two three-position switches for each channel
(main only), the first sets which filter the channel will be
passed through and the second assigns the channel to
either end of the cross-fader. There’s a set of lights above
the cross-fader that indicate if a channel is assigned, but
it doesn’t signify to which side.
Hidden Features
Levels can be set inside the unit to suit a particular
installation and to avoid damage to any PA
equipment. The unit can also have some ‘ears’ bolted
on the side to mount it in a standard 19in rack space.
The internal settings are described in the manual and
include the ability to reduce the filter resonance and
even turn it off completely. The phono inputs can be
switched to line level. Even the gain can be
deactivated on the main channels. As default the mic
channels are not routed to booth or record, but this
can be changed, but to both only.
Cue Control
A&H have not only surpassed themselves with great control over cue for each
vital part of the mixer, but managed to inject some humour in there too –
albeit unintentional. The volume knob actually goes up to 11 compared to
every other numbered volume knob which go up to ten - how Spinal Tap. Nice
work! On a more serious and pleasing note, the Xone:92 has two headphone
outputs (small and large), so you won’t be stuck out if you lose the adaptor.
The output can be set to hear the music before the effect of the cue and after.
Split monitoring changes the master VU meters to display cue and master
separately. Each channel is selected by an illuminated push button. When no
channel is selected for cueing, the main mix is played through the
headphones. The two auxiliary channels can be selected for monitoring and
the cue channel can be blended with the main output to check the mix.
Sander Kleinenberg on the Xone:92
"It's a great and solid looking machine. The new features are a welcome
improvement to the already exceptional sound quality of Allen & Heath’s
mixers. If you look at price, sound and versatility, I would say that this unit
is at the top of the current game.
"I was pretty impressed by the change of how the High, Mid and Low range
is better handled by this mixer. Previous models used to cut a frequency
dead right at the end of the frequency. Now with the new steps it's much
smoother and better to handle.
“However, if there’s one complaint, I talked with the engineer of the mixer
for a while and told him that I would like to see the tab function for the
MIDI clock to be changed to an automated one."
CHANNEL LAYOUT
Connections
Each of the four main channels has both line and phono inputs on
RCA. The two auxiliary sends and the returns use jacks. Mic inputs are
XLR only. The master section has two independent Mix outs - one on
XLR and one on jacks with separate volume control. The booth output
is also on jacks and can be muted and even set to mono. There’s also
the standard MIDI output port and a record output on RCA.
considered the heart conditions of installers here and kept
it tame; it can also be turned off internally for the super
paranoid.
The filters do not have any effect on the signal to either of
the auxiliaries, so when applying external effects and using
a filter at the same time there is no correlation in the two
sounds. The filters cut some of the high frequencies and
low frequencies in their fully open state. However, with the
resonance up half way this flattens out the frequency levels
to normal. One of the greatest things about the filter, apart
from its sound, is that the frequency controls can be joined
together. They can also be assigned individually or paired
to the cross-fader. When controlling both filters using the
frequency knob or cross-fader, one channel can be set to a
hi pass filter and the other to a lo pass filter. On one
complete rotation it creates a unique ability to mix between
tracks using the filters and it sounds wonderfully slick. For
example, in a middle setting one channel will have
everything below 1kHz filtered out, with everything above
1kHz filtered out on the other.
All channels can be set to either filter and can even be
switched from one to the other. By using drastically
different settings on each, the DJ can achieve some pretty
awesome results. There are also two sine wave LFOs (low
frequency oscillators) with a tap tempo feature. The tempo
can be doubled or halved. LFO depth can also be adjusted.
Each filter can even be controlled by the cross-fader with
the LFOs still interacting.
