SYS-LINK Applications Note AP5736 1
SYS-LINK explained
SYS-LINK (system link) is the Allen & Heath connection standard for linking two consoles together to
expand the number of input channels feeding the mixes. One becomes the ‘slave’ to the other ‘master’
console. All the slave console mix busses including main LR, groups and auxes connect directly to the
master console mix busses without using up valuable input channels. The PFL/AFL system is also
linked so that all channels can be monitored using the master console headphones and meters. The
slave console master section is not used as its signals are taken before the mix inserts and output
faders. Both consoles must have the SYS—LINK option fitted. A single multiway cable is all that is
required to link the WZ
3
to another Allen & Heath console fitted with SYS-LINK.
SYS-LINK versions 1 and 2
The MixWizard WZ
3
uses the more recent SYS-LINK Version 2 standard. This benefits from balanced
interconnections which allow longer cable length with less chance of noise and interference pickup
than the earlier, unbalanced SYS-LINK Version 1. Both versions operate at -2dBu line level. V1 uses
the 25way D-type connector. V2 uses the 37way D-type connector. Two consoles fitted with SYS-LINK
V2 can be linked using a 36-core shielded cable wired one to one to two 37way male D-type
connectors. It is also possible to connect between SYS-LINK V2 and V1. This requires a 37way to
25way adapter cable wired to unbalance the connections. Wiring details are provided later. The
interconnecting cable is not included in the kit and should be sourced elsewhere or ordered separately
from Allen & Heath.

Introducing the MixWizard
The Allen & Heath MixWizard series of consoles includes several models. This user guide
describes the WZ

20S consoles are described in separate publications. For further information on
3
16:2 and WZ312:2 stereo models. The 4 group WZ314:4:2 and stereo
the MixWizard series please refer to the Allen & Heath web site.
The MixWizard is a compact console designed for
professional live sound mixing. It is built to the same
high standards as our top of the range consoles, with
individual circuit cards, potentiometers nutted to the
panel for absolute strength, steel chassis, and no
compromise circuit design ensuring the finest sonic
performance.
The console can be operated free standing or in a
19” rack or flightcase. It is supplied with protective
side trims fitted. These can be removed for rack
mounting. The rear connector pod can be easily
rotated for rear facing or underside connectors when
rack mounted.
Both models feature a 4 band semi-parametric EQ
and high pass filter per mic/line channel, 6 aux sends
with combinations of pre/post switching, 100mm
faders, a built-in dual effects processor with
parameter control using Allen & Heath PC software,
dedicated mono output with separate fader and
innovative operating mode for aux fed sub systems,
additional AB stereo output, comprehensive metering
and engineers monitoring, dual redundant backup
supply input, and a lamp socket.

3
12:2 provides 10 mono mic/line inputs, 2 full
channel dual stereo inputs, and 2 stereo return
inputs, a total of 22 input connections.
The base of the console can be removed to access a
host of internal option jumpers. These set user
preference for the aux, direct output and AB sources.
The aux outputs are impedance balanced but may
be electronically balanced if required by fitting an
optional part. A kit is also available to fit the optional
Sys-Link II output card which allows the console to
be linked to other Allen & Heath consoles.
Software for editing the effects parameters using a
PC computer can be downloaded free from the Allen

Connecting Power
EXTERNAL DC IN
RECOMMENDED ALLEN&HEATH POWER SUPPLY
REFER TO USER GUIDE FOR DET AILS
Read and understand the Important Safety Instructions printed at the start of this guide,
and the warnings printed on the rear of the console. Check that your local mains supply is
within the 100-240V operating voltage range allowed. Check that the correct mains lead
with moulded plug has been supplied with your console. Make sure that the IEC mains plug
is pressed fully into the panel socket before switching on.
Grounding
The connection to ground in an audio system is important for two reasons:
1. SAFETY — To protect the operator from high voltage electric shock, and
2. AUDIO PERFORMANCE — To minimise the effect of ground (earth) loops which result in
audible hum and buzz, and to shield the audio signals from interference.

For safety it is important that all equipment grounds are connected to mains ground so that
exposed metal parts are prevented from carrying high voltage which can injure or even kill
the operator. Do not disconnect the ground connection in the mains lead. It is
recommended that the system engineer check the continuity of the safety ground from all
points in the system including microphone bodies, turntable chassis, equipment cases, rack
metalwork and so on.
Switching the console on and off
It is good practice to turn power amplifiers off before switching the console and any other
connected equipment on or off. This prevents any unexpected clicks or thumps when the
equipment is powered up.
Turn amplifiers and powered speakers on last and off first.
To turn the console on, press the ON/OFF switch next to the IEC mains input socket. To
turn the console off, press this switch again.
Connecting a backup supply
A socket is included for plugging in an optional backup power supply. This provides the
reassurance of power supply dual redundancy, a feature usually found only in expensive top
end consoles. The console uses diode combining technology so that both supplies can be
powered at the same time. One will automatically take over should the other stop working.
The recommended backup supply for the MixWizard is the Allen & Heath MPS12 power unit.
Refer to the user guide which comes with this supply.
Only plug the recommended Allen & Heath power unit into this socket. Do not
attempt to modify any other power unit to work with the console. Do not attempt to modify or
extend the DC power cable that comes with the supply.
The console can work with just the internal supply powered by mains, or just the backup
supply, or with both powered at the same time. To ensure uninterrupted performance in the
unlikely event of a failure, we recommended that both supplies are powered.

Dual stereo inputs
stereo inputs which can be used separately, mixed together or split so
that one feeds the channel, the other routes direct to LR. For example,
you could mix two sound effects playback devices or two reverb
returns together into one channel.
channels, letting you mix many inputs in a small space. The L input
signal normals through the R input socket so that a mono source may
be plugged in to feed both left and right sides of the stereo channel.
ST1, ST3
Unbalanced TRS inputs. The GAIN control adjusts from
fully off to +16dB gain. Press the ST1 (ST3) switch to turn the input
on.
Routing mode switch
operation. In the normal up position the ST1 (ST3) signal mixes with
ST2 (ST4) into the stereo channel. When pressed the signal is routed
direct to the LR mix instead of the channel. This lets you use these
inputs as simple stereo returns in addition to the full stereo channels,
providing four independent stereo sources to the LR mix.
ST2, ST4
Balanced TRS inputs. The GAIN control adjusts from
fully off to +16dB gain. Press the ST2 (ST4) switch to turn the input
on. These inputs always feed the stereo channels.
EQ
A 4-band fixed frequency EQ provides independent control of
four frequency bands. HF and LF are shelving filters which affect high
frequencies above 12kHz, and low frequencies below 80Hz
respectively. HM and LM are bell shaped peak/dip filters which affect
frequencies centred around 2.5kHz and 250Hz respectively. These
have a width (Q) of 1.8. All bands can be boosted or cut by up to 15dB
and have a centre detented 0dB position.
AUX SENDS
These work as described for the mono channel. The
L and R sides of the stereo signal sum together to feed each aux in
mono. This can be changed using an internal jumper option so that L
feeds auxes 1,3 and R feeds auxes 2,4.
BAL
Balances the level of the L signal against the R signal to
compensate for differences in the source signal, or to position the
signal within the stereo image.
detented for quick resetting.
MUTE
When pressed the channel signal is turned off. This affects
the feed to the LR mix, and pre and post-fade aux sends. The red
indicator lights when the channel is muted.
PFL
Press PFL to listen to the summed L+R pre-fade channel signal
in the headphones or AB monitor (if configured) without affecting the
main outputs. The console main LR meters are interrupted with the
channel signal. The red PK indicator half lights to show that PFL has
been selected on that channel.
PEAK
The red indicator illuminates when the channel pre-fade
signal is within 5dB of clipping. This gives you enough warning to
reduce the GAIN control before you hear signal distortion.
SIGNAL
The green signal presence indicator lights when the
channel pre-fade signal is greater than -12dBu.
