General Precautions
Damage :
To prevent damage to the controls and cosmetics avoid placing heavy objects on the
control surface, scratching the surface with sharp objects, or rough handling and vibration.
Environment :
Protect from excessive dirt, dust, heat and vibration when operating and storing.
Avoid tobacco ash, smoke, drinks spillage, and exposure to rain and moisture. If
the console becomes wet, switch off and remove mains power immediately. Allow to
dry out thoroughly before using again.
Cleaning :
Avoid the use of chemicals, abrasives or solvents. The control panel is best cleaned
with a soft brush and dry lint-free cloth. The faders, switches and potentiometers are
lubricated for life. The use of electrical lubricants on these parts is not recommended. The fader and potentiometer knobs may be removed for cleaning with a warm
soapy solution. Rinse and allow to dry fully before refitting them.
Transporting :
The console may be transported as a free-standing unit or mounted in a rack or
flightcase. Protect the controls from damage during transit. Use adequate packing if
you need to ship the unit.
Hearing :
To avoid damage to your hearing do not operate any sound system at excessively
high volume. This also applies to any close-to-ear monitoring such as headphones.
Continued exposure to high volume sound can cause frequency selective or wide
range hearing loss.

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.
3. 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.

Audio Connections
The MixWizard uses professional grade 3 pin XLR and 1/4" TRS (3 pole) jack sockets. To ensure best performance, we recommend that you use high quality audio cables and connectors, and take time to check for reliable and accurate cable assembly. It is well known that most audio system problems are due to faulty or sub
standard interconnecting leads. The following mating plugs may be used to connect audio signals to the console:

Tip
Ring
Avoid reversing + and - on balanced connections as this will result in reversed polarity (out of phase) signals
which may cause signal cancellation effects.
Where long cables runs are required, balanced interconnections should be used. However, line level interconnections between more affordable 2-wire (signal, ground) unbalanced equipment and the console are unlikely to
cause problems if the cables are kept shorter than 10 meters or so. Refer to the wiring diagrams on the opposite page.
Dealing with Ground Loops, Buzz and Interference
For optimum performance all audio signals should be referenced to a solid, noise-free ground (earth) point, frequently referred to as the ‘star point’ or ‘clean earth’.
A ground loop is created when potential differences exist between grounds at different points in the system, and
the signal has more than one path to ground. In most cases ground loops do not result in audible problems.
Should you experience hum or buzz caused by a ground loop, check first that each piece of equipment has its
own separate path to ground. If so, operate ground lift switches on connected equipment in accordance with the
instruction manuals. Alternatively disconnect the cable screen at the destination end only. This breaks the offending loop while keeping the signal shielding down the length of cable.
WARNING For operator safety do not remove the ground (earth) connection in the
power lead of the console or connected equipment.
To avoid interference pickup keep audio cables away from mains power units and cables, thyristor dimmer units,
computer equipment and mobile phones. Where this cannot be avoided, cross the cables at right angles to minimise interference
A note about balanced connections
A differentially balanced connection has two signal wires, signal + (hot) and signal - (cold) and a shield. The signal
source generates positive going polarity down the + wire and negative polarity down the – wire. The destination
input stage accepts the + signal on its non-inverting (+) input pin, but it inverts the – signal, adding it to the +
signal. The result is that the wanted signal is boosted. Now examine what happens when unwanted interference
(hum and noise) is induced into the cable. The noise is induced equally and with the same polarity into both
wires. At the destination input the – wire signal gets inverted and added to the + signal. Because the polarity is
the same on both input wires the noise cancels itself out at this input. For this interference rejection to work it
is important that the source, the cable and the destination input are all balanced. Balancing provides greatest
advantage with low level signals such as those produced by microphones.
An impedance balanced output provides similar interference rejection, but without the signal drive on the - wire.
It does not generate a negative polarity signal at its – output. Instead, the – wire has no signal but is held at the
same impedance as the + wire. This means that both wires pick up the noise equally resulting in cancellation as
described above.

DIRECT OUTPUT The mic/line channel direct output is available on an impedance balanced TRS jack. It is a line level signal operating at 0dBu. The source is set
using an internal option jumper for each channel. The factory default setting is pre-fade
(following the pre/post-EQ setting). This may be changed to post-fade if preferred.
The direct outputs provide a useful source for multitrack recording. Many users prefer
pre-fade sends for this application so that the live show fader movements do not affect
the recording which can be mixed later. Another application is channel effects sends.
For example, a reverb unit may be dedicated to work with the lead vocalist channel
only. Using a post-fade direct output instead of an aux send frees up that aux mix for
other purposes.

WZ4 14:4:2 User Guide
GROUP (Aux), L, R, M OUT The main console mix outputs are on
balanced XLR. These produce +4dBu when the meters read ‘0’. The M output can be switched to provide a mono sum of the post-fade L and R signals,
or the PFL/AFL engineer’s wedge output.
USO RESTRITO
The L and R outputs typically feed the house PA system in live sound mixing,
or a 2-track recorder in studio mixing. In FOH mode, the M output can provide an additional feed for a mono fill speaker or zone, or be used as the main
feed into a mono PA. In monitor mode the M output feeds the engineer’s
wedge monitor speaker with the AFL signal interrupted by PFL.
Group 1 – 4 outputs can be used to provide additional zone or special feeds,
or for multitrack recording. In FOH mode they are often left unconnected
where the groups are used as ‘subgroups’ for grouped level control and/or
inserted processing. In monitor mode, the group and LR output XLRs and
inserts become the aux mix masters. This configures the console with 6 main
mix outputs capable of driving the stage monitors.
AUX OUT 1-6 Each aux send is available on an impedance balanced TRS
jack operating at -2dBu line level. An internal option is available to fit a balanced line driver IC to provide an electronically balanced output operating at
+4dBu. Note that it is not usual to require this option as the impedance balanced standard drive provides sufficient interference rejection when feeding
balanced equipment inputs.
The aux sends are typically used to feed monitors, effects devices such as reverb and delay, and for special mix requirements. In monitor mode, these outputs reverse with the groups and LR connections.
MATRIX OUT A, B Each matrix output is available on an impedance
balanced TRS jack operating at -2dBu line level. An internal option is available
to fit a balanced line driver IC to provide an electronically balanced output
operating at +4dBu. Note that it is not usual to require this option as the impedance balanced standard drive provides significant interference rejection
when feeding balanced equipment inputs.
The matrix outputs are typically used for stereo or mono recording or broadcast feeds, delay and fill speakers, zone feeds, hearing assist loops and so on.
2-TRACK IN and OUT These connections are unbalanced on RCA
phono sockets for connection to popular recording and playback devices such
as CD, MiniDisc, computers and tape machines. Nominal line level is -2dBu.
The 2-track SEND always follows the post-fade LR mix regardless of mode
switch configuration. The 2-track RETURN can be used for monitoring a stereo recording, or as a simple stereo input for playback of walk-in and background music.
MONITOR OUT These impedance balanced line level TRS jack outputs
follow the post-level monitor signal. Separate sockets are provided for the L
and R signals. Use these to feed local speaker or other in-ear monitor systems.

the internal 0dBu operating level of the channel. Provides a variable 50dB
range from +10 to +60dB gain (mic), or -10 to +40dB (line, pad selected).
The gain should be set using PFL so that the console meters average ‘0’
with loudest moments lighting ‘+6’. Reduce gain if the red peak indicator
lights.
Important note on setting channel levels: Use PFL to set the
GAIN controls for correct signal level through each channel. Use the
faders to balance each signal in the mix. We do not recommend setting
the faders to ‘0’ and mixing using the GAIN controls.
HPF Switches in the channel high pass filter. This attenuates frequencies below 80Hz by 12dB per octave. The filter is pre-insert, pre-EQ.
Select the HPF to reduce low frequency noise such as microphone popping, stage noise and tape transport rumble.
EQ A 4-band semi parametric EQ provides independent control of
four frequency bands. Use EQ IN to compare the sound with the equaliser switched in or out of circuit. 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 around a centre point which can be swept from 500Hz to
15kHz and 35Hz to 1kHz respectively. These have a width (Q) of 1.8.
All bands can be boosted or cut by up to 15dB and have a centre detent
0dB position.

Check for the best microphone selection and placement before using the
EQ. Start with the EQ set flat and apply only as much boost or cut as is
really needed. When dealing with problem frequencies cut rather than
boost where possible.

AUX SENDS These rotary controls adjust how much channel
signal is mixed to the aux outputs. Each of the 6 auxes has its own
control. They adjust from fully off to +6dB boost. Unity gain 0dB is
marked at 3 o’clock position. Auxes 1-4, 5-6 are switched pre/post.
These settings may be changed if preferred by repositioning internal
jumper link options. They offer many different combinations of pre
and post-fade sends, and a post-EQ option for the pre-fade sends.
More detail is provided in OPTIONS later in this guide.
Pre-fade aux sends are not affected by the channel fader movements.
These are typically used to feed stage monitors. In most cases users
also prefer that the monitor sends are not affected by inserted processors or the channel EQ. Post-fade aux sends follow the channel
faders and are typically used to send a proportion of the channel
signal to an effects device such as reverb or delay. Note that postfade sends may be preferred when the console is configured in monitor mode so that the faders become ‘masters’ for all monitor mixes.
Pre or post-fade sends may also be used for special applications such
as recording, zone feeds, clean feeds and aux fed subs.
PRE When pressed, the pre-fade channel signal is sent to the associated auxes. When released, the post-fade signal is sent. Auxes
1 to 4 and 5, 6 are grouped for pre/post switching. You can change
this by repositioning the internal option jumpers.

you could mix two sound effects playback devices or two reverb returns together into one channel. This can be useful in saving channels,
letting you mix many inputs in a small space. The L input signal normals

REV These switches reverse the function of the group and aux masters. They are recessed to prevent accidental operation. Use a pen or
pointed object to set their position. In the up position (flush with the
panel), the group is controlled by the fader and the aux by the rotary
master. This is typical for FOH mode where the faders are used for subgroups feeding the main stereo mix. When pressed, the aux uses the
fader as the master and the group is moved to the rotary control. The
aux mix is now presented to rear Group XLR complete with insert. The
group mix appears at the Aux TRS jack. This is used for monitor mode
where the auxes are the main mix feeding the stage monitors. You can
select any combination for the FOH and monitor mode, for example, just
3, 4 giving you two fader subgroups, two monitor sends on faders, and
main LR mix.
Note: The groups always feed the matrix and the subgroup controls
(PAN and GRP TO LR) regardless of mode. This means the group mix
can still perform a useful function when the console is configured in monitor mode.

WARNING: We recommend you turn off the signal
generator once you have finished using it to test and line up

show.
MATRIX The matrix provides 2 additional console outputs. It is a
‘mixer within a mixer’ taking its source from the groups and main mix.
It can be used to provide duplicate main outputs or to create new mixes
from the main outputs. The controls are positioned conveniently away
from the live performance controls to avoid accidental operation.
Each of the 4 groups, L and R can be mixed independently into the matrix. The source is derived post-fader. Adjust the level clockwise from
fully off to +6dB boost. Use the LEVEL control to adjust the matrix
output level from fully off to a maximum boost of +6dB. The ‘0dB’ positions are marked. The matrix output can be muted. The post-level
signal can be monitored using the AFL switch.
Use the matrix to create special mixes such as delay, fill and zone speakers, recording and broadcast feeds, hearing assist loop and so on.

User Options
The MixWizard has a versatile architecture which should satisfy most applications you may encounter without modification. However, the following internal options provide alternative settings for those applications that may demand them. Access is required to the internal assemblies. pluggable jumper
links are used in most places and also some links require cutting and soldering
a solder bridge.
REMOVE 4x M4 POZI SCREWS PER SIDE
REMOVE SIDE TRIMS
REMOVE M4 POZI SCREW PER SIDE
ROTATE POD
Remove the base
Start by removing the side trims if fitted using a
Pozi crosshead screwdriver. Release the two M4 Pozi head pod securing
screws and rotate the connector pod to gain access to the three M3 rear
base fixing screws. Use a Torx starhead screwdriver to remove these. Rotate the pod again to remove the four M3 underside base screws using the
Torx driver. Carefully lift off the base.
USO RESTRITO

Jumper Options:
Fit the options required. Set the option jumpers to the required positions.
Make sure they are pressed fully home. Check that all channels are correctly
set and all options fitted according to their instructions. Make sure that no
debris or parts are left loose inside the console.
ROTATE POD
REMOVE 4x M3 TORX SCREWS
Solder Options:
Solder options require some ability with a soldering iron, if you have any reservations then please contact your local service centre to carry out this procedure for you.
See page opposite for details on how to modify the solder options.
Refit the base Carefully reposition the base. Refit the fixing screws.
LIFT OFF BASE
Lock the connector pod in the required position using the securing screws.
Refit the side trims if required.
IMPORTANT: Check carefully that all channel options are correctly
set as required. Errors on one or more channels now may cause user problems later. We recommend that you write the repositioned option settings
on a label and adhere this to the rear panel. This would provide a helpful
reference to other users of the console.

Aux pre/post insert / EQ
Factory default for the
mono channel pre-fade auxes is pre-insert, pre-EQ. This is
popular with many users mixing monitors from FOH. It prevents the channel EQ and inserted compressors affecting the
monitor mix. Move the jumper from A to B to change this to
post-insert, post-EQ if preferred. Note that auxes are always
post-mute.

Direct output source
Factory default is pre-fader.
This is common for live recording to multitrack. The live mix
fader movements do not affect the recording. Move the jumper from C to D to change to post-fade. Post-fade is appropriate when using the output as a direct channel effects send.

Aux 1-4 = switched, Aux 5-6 = switched. You can change
these settings for different combinations of pre/post or

the system block diagram to explore the possibilities. Make
sure you set all mono and stereo channels the same. We recommend you only change these settings if absolutely necessary.

Stereo/Mono aux source
The stereo channels can
feed the auxes with a mono sum of L+R, or be configured so
that L feeds the odd numbered auxes, and R the even. This is
preferred when using odd/even auxes as stereo pairs. Factory
default is the mono setting.

Output balance options
The aux and matrix outputs
are impedance balanced as standard operating at nominal -2dBu
and with +21dBu maximum drive. They provide similar interference rejection to electronically balanced outputs when connected
to balanced equipment inputs. An electronically balanced option
is available if you require nominal +4dBu and higher output drive
up to +26dBu over very long cable runs. However, it is not usually necessary to fit this option as the impedance balanced drive
satisfies most applications. Check that you really need the option
before fitting it.

For each aux master, snip the legs of the two zero ohm
resistor links next to each IC. This removes them from
the circuit. Now solder the option IC into the socket.
Observe the correct IC pin1 orientation and make sure its
legs are correctly aligned with the socket. Test the output
once the work is complete. You should measure the
same level but opposite polarity signal between + (hot)
and ground, and – (cold) and ground.
