USERGUIDE
INTRODUCTION
Thank you for purchasing a Soundcraft mixer. We take great pride in our latest addition to the
Spirit range of mixing consoles - you have taken a step in the right direction and should never
look back.
The packaging which your Spirit E Series arrived in, forms part of the product and must be
retained for future use.
Owning a Soundcraft console brings you the expertise and support of one of the industrys
leading manufacturers, and the results of nearly 3 decades of supporting some of the biggest
names in the business. Our knowledge has been attained through working in close contact with
leading professionals and institutes to bring you products designed to get the best possible
results from your mixing.
Built to the highest standards using quality components and surface mount technology, the
Spirit E Series is designed to be as easy to use as possible. We have spent years researching
the most efficient methods of control for two key reasons:
1) Engineers, musicians, writers and programmers all need to have very few interruptions to the
creative process; our products have been designed to be almost transparent, allowing this
process to breathe.
2) Whether performing or recording, time is a very expensive and rare commodity. Our products
have a user interface which is recognised by millions to be the industry standard because of its
efficiency.
The sonic qualities of our products are exemplary - some of the same circuits which are used on
our most expensive consoles are employed in the Spirit E Series, bringing you the great Soundcraft
quality in a small format console without compromise.
You will also be glad to know you have a one year warranty with your product from the date of
purchase. The Spirit E Series has been designed using the latest high-end software based
engineering packages. Every console from Soundcraft has been proven to stand up to all the
stress and rigours of modern day mixing environments.
The entire Spirit E Series is manufactured using some of the most advanced techniques in the
world, from high density surface mount PCB technology, to computer aided test equipment able
to measure signals well outside the range of normal hearing. As each console passes through
to be quality checked before packing, there is also a human listening station. Something we
have learnt over the years is that the human touch counts - and only by using people can you
ensure the product meets the high demands of the user.
ADVICEFORTHOSEWHOPUSHTHEBOUNDARIES
Although your new console will not make any noise until you feed it signals, it has the capability
to produce sounds which when monitored through an amplifier or headphones can damage
hearing over time.
Please take care when working with your audio - if you are manipulating controls which you
dont understand (which we all do when we are learning), make sure your monitors are turned
down. Remember that your ears are the most important tool of your trade, look after them, and
they will look after you.
Most importantly - dont be afraid to experiment to find out how each parameter affects the
sound - this will extend your creativity and help you to get the best from your mixer and the
most respect from your artists and audience.

INSTALLINGTHEMIXER
Correct connection and positioning of your mixer is important for successful and trouble-free
operation. The following sections are intended to give guidance with cabling, connections and
configuration of your mixer.
Choose the mains supply for the sound system with care, and do not share sockets or
earthing with lighting dimmers.
Position the mixer where the sound can be heard clearly.
Run audio cables separately from dimmer wiring, using balanced lines wherever possi-
ble. If necessary, cross audio and lighting cables at right angles to minimise the pos-
sibility of interference. Keep unbalanced cabling as short as possible.
Check your cables regularly and label each end for easy identification.
SAFETYPRECAUTIONS
For your own safety and to avoid invalidation of the warranty please read this section carefully.
In particular, you should also read the Cautions and Warnings on pages 5-6 of this manual.

WIRINGUP
Please refer to pages 36/37 for additional wiring details.
MicInputs1-4
The MIC input accepts XLR-type connectors and is designed to suit a wide range of
BALANCED or UNBALANCED low-level signals, whether from delicate vocals requir-
ing the best low-noise performance, or drum kits needing maximum headroom.
Professional dynamic, condenser or ribbon mics are best because these will be
LOW IMPEDANCE. While you can use low-cost HIGH IMPEDANCE mics, you do not
get the same degree of immunity to interference on the microphone cable and as a
result the level of background noise may be higher. If you turn the PHANTOM
POWER on, the socket provides a suitable powering voltage for professional con-
denser mics.
The input level is set using the input GAIN knob.
The LINE input offers the same gain range as the MIC input, but at a higher input
impedance, and is 2 dB less sensitive. This is suitable for most line level sources.
LineInput
Accepts 3-pole A gauge jacks, or 2-pole mono jacks which will automatically ground
the cold input. Use this input for sources other than mics, such as keyboards,
drum machines, synths, tape machines or guitars. The input is BALANCED for low
noise and immunity from interference, but you can use UNBALANCED sources by
wiring up the jacks as shown, although you should then keep cable lengths as short
as possible to minimise interference pick-up on the cable. Note that the ring must
be grounded if the source is unbalanced. Set the input level using the GAIN knob,
starting with the knob turned fully anticlockwise. Unplug any MIC connection when
using the LINE input.
InsertPoint
The unbalanced, pre-EQ insert point is a break in the channel signal path, allowing
limiters, compressors, special EQ or other signal processing units to be added in
the signal path. The Insert is a 3-pole A gauge jack socket which is normally
bypassed. When a jack is inserted, the signal path is broken, just before the EQ
section.
The signal from the channel appears on the TIP of the plug and is returned on the
RING, with the sleeve as a common ground.
The Send may be tapped off as an alternative pre-fade, pre-EQ direct output if
required, using a lead with tip and ring shorted together so that the signal path is
not interrupted.

Stereo Inputs 1-10
These accept 3-pole A gauge jacks, or 2-pole mono jacks which will automatically
ground the cold input. Use these inputs for sources such as keyboards, drum
machines, synths, tape machines or as returns from processing units. The input is
BALANCED for low noise and immunity from interference, but you can use
UNBALANCED sources by wiring up the jacks as shown, although you should then
keep cable lengths as short as possible to minimise interference pick-up on the
cable. Note that the ring must be grounded if the source is unbalanced.
Mono sources can be fed to both paths by plugging into the Left jack only (NB
Channels 3-6 have a dedicated mono switch to perform this function) .
MixInserts
The unbalanced, pre-fade Mix insert point is a break in the output signal path to
allow the connection of, for example, a compressor/limiter or graphic equaliser.
The Insert is a 3-pole A gauge jack socket which is normally bypassed. When a
jack is inserted, the signal path is broken, just before the mix fader.
The mix signal appears on the TIP of the plug and is returned on the RING. A Y lead
may be required to connect to equipment with separate send and return jacks as
shown below:
MixOutputs
The MIX outputs are on XLRs, wired as shown, and incorporate impedance balanc-
ing, allowing long cable runs to balanced amplifiers and other equipment.

14
USERGUIDE
AuxOutputs
The Aux outputs are on 3-pole A gauge jack sockets, wired as shown on the left, and
are balanced, allowing long cable runs to balanced amplifiers and other equipment.
Headphones
The PHONES output is a 3-pole A gauge jack, wired as a stereo output as shown,
ideally for headphones of 2 W or greater. 8W headphones are not recommended.
Polarity(Phase)
You will probably be familiar with the concept of polarity in electrical signals and
this is of particular importance to balanced audio signals. Just as a balanced
signal is highly effective at cancelling out unwanted interference, so two micro-
phones picking up the same signal can cancel out, or cause serious degradation of
the signal if one of the cables has the +ve and -ve wires reversed. This phase
reversal can be a real problem when microphones are close together and you should
therefore always take care to connect pins correctly when wiring audio cables.
GroundingandShielding
For optimum performance use balanced connections where possible and ensure
that all signals are referenced to a solid, noise-free earthing point and that all signal
cables have their screens connected to ground. In some unusual circumstances, to
avoid earth or ground loops ensure that all cable screens and other signal earths
are connected to ground only at their source and not at both ends.
If the use of unbalanced connections is unavoidable, you can minimise noise by
following these wiring guidelines:
On INPUTS, unbalance at the source and use a twin screened cable as
though it were balanced.
On OUTPUTS, connect the signal to the +ve output pin, and the ground of
the output device to -ve. If a twin screened cable is used, connect the
screen only at the mixer end.
Avoid running audio cables or placing audio equipment close to thyristor
dimmer units or power cables.
Noise immunity is improved significantly by the use of low impedance
sources, such as good quality professional microphones or the outputs from
most modern audio equipment. Avoid cheaper high impedance micro-
phones, which may suffer from interference over long cable runs, even with
well-made cables.
Grounding and shielding is still seen as a black art, and the suggestions above are
only guidelines. If your system still hums, an earth/ground loop is the most likely
cause. Two examples of how an earth loop can occur are shown below.

PROBLEMSOLVING
Basic problem solving is within the scope of any user if a few basic rules are
followed.
Get to know the Block Diagram of your console (see page 38).
Get to know what all parameters and/or connections in the system are
supposed to do.
Learn where to look for common trouble spots.
The Block Diagram is a representative sketch of all the components of the con-
sole, showing how they connect together and how the signal flows through the
system. Once you have become familiar with the various component blocks you
will find the Block Diagram is quite easy to follow and you will have gained a
valuable understanding of the internal structure of the console.
Each Component has a specific function and only by getting to know what each
part is supposed to do will you be able to tell if there is a genuine fault! Many
faults are the result of incorrect connection or control settings which may have
been overlooked.
Basic Troubleshooting is a process of applying logical thought to the signal path
through the console and tracking down the problem by elimination.
Swap input connections to check that the source is really present. Check
both Mic and Line inputs.
Eliminate sections of the channel by using the insert point to re-route the
signal to other inputs that are known to be working.
Route channels to different outputs or to auxiliary sends to identify prob-
lems on the Master section.
Compare a suspect channel with an adjacent channel which has been
set up identically. Use SOLO to monitor the signal in each section.
Insert contact problems may be checked by using an insert bypass jack
with tip and ring shorted together as shown below. If the signal appears
when the jack is inserted it shows that there is a problem with the
normalling contacts on the jack socket, caused by wear or damage, or
often just dirt or dust. Keep a few in your gig tool box.
If in doubt please contact Soundcraft customer support.

are best because these will be LOW IMPEDANCE. You can use low-cost HIGH IMPED-
ANCE mics, but the level of background noise will be higher. If you turn the PHANTOM
POWER on (top right-hand side of the mixer) the socket provides a suitable powering
voltage for professional condenser mics.
TAKE CARE when using unbalanced sources, which may be damaged by the phantom
power voltage on pins 2 & 3 of the XLR connector.
Unplug any mics if you want to use the LINE Input. The input level is set using the GAIN
knob.
2 LineInput
Accepts 3-pole A gauge (TRS) jacks. Use this input for sources other than mics, such
as keyboards, drum machines, synths, tape machines or DId guitars. The input is
BALANCED for low noise and top quality from professional equipment, but you can use
UNBALANCED sources by wiring up the jacks as shown below, although you should then
keep cable lengths as short as possible. Unplug anything in the MIC input if you want to

4 Gain
This knob sets how much of the source signal is sent to the rest of the mixer. Too high, and
the signal will distort as it overloads the channel. Too low, and the level of any background
hiss will be more noticeable and you may not be able to get enough signal level to the
output of the mixer.
Note that some sound equipment, particularly that intended for domestic use, operates at
a lower level (-1 dBV) than professional equipment and will therefore need a higher gain
setting to give the same output level.
See Initial Setup on page 23 to learn how to set GAIN correctly.
5 Equaliser
The Equaliser (EQ) allows fine manipulation of the sound, particularly to improve the
sound in live PA applications where the original signal is often far from ideal and where
slight boosting or cutting of particular voice frequencies can really make a difference to
clarity. There are three sections giving the sort of control usually only found on much larger
mixers. The EQ knobs can have a dramatic effect, so use them sparingly and listen
carefully as you change any settings so that you get to know how they affect the sound.
H EQ
Turn to the right to boost high (treble) frequencies above 12kHz by up to 15dB, adding
crispness to cymbals, vocals and electronic instruments. Turn to the left to cut by up to
15dB, reducing hiss or excessive sibilance which can occur with certain types of micro-
phone. Set the knob in the centre-detented position when not required.
MID EQ
There are two knobs which work together to form a SWEPT MID EQ. The lower knob
provides 15dB of boost and cut, just like the HF EQ knob, but the frequency at which this
occurs can be set by the upper knob over a range of 14 Hz to 3kHz. This allows some
truly creative improvement of the signal in live situations, because this mid band covers
the range of most vocals. Listen carefully as you use these controls together to find how
particular characteristics of a vocal signal can be enhanced or reduced. Set the lower
knob to the centre-detented position when not required.
L EQ
Turn to the right to boost low (bass) frequencies below 6 Hz by up to 15dB, adding
warmth to vocals or extra punch to synths, guitars and drums. Turn to the left to cut low
frequencies by up to 15dB for reducing hum, stage rumble or to improve a mushy sound.
Set the knob to the centre-detented position when not required.
6 AuxSends
These are used to set up separate mixes for FOLDBACK, EFFECTS or recording, and the
combination of each Aux Send is mixed to the respective Aux Output. For Effects it is
useful for the signal to fade up and down with the fader (this is called POST-FADE), but for
Foldback or Monitor feeds it is important for the send to be independent of the fader (this
is called PRE-FADE).
AUX SENDS 1 and 2 are both globally switchable between pre and post-fade (see master
section on page 21/22).
7 PAN
This control sets the amount of the channel signal feeding the Left and Right MIX buses,
allowing you to move the source smoothly across the stereo image. When the control is
turned fully left or right you are able to route the signal at unity gain to either left or right
outputs individually.

8 MUTE
All outputs from the channel except inserts are on when the MUTE switch is released and
muted when the switch is down, allowing levels to be pre-set before the signal is required.
9 INPUTCHANNELFADER
The 1 mm FADER, with a custom-designed law to give even smoother control of the
overall signal level in the channel strip, allows precise balancing of the various source
signals being mixed to the Master Section. You get most control when the input GAIN is
set up correctly, giving full travel on the fader. See the Initial Setup section on page 23
for help in setting a suitable signal level.
0 SOLO
When the latching SOLO switch is pressed, the pre-fade pre-mute signal is fed to the
headphones, control room output and meters, where it replaces the MIX. The SOLO LED
on the Master section illuminates to warn that a SOLO is active. This is a useful way of
listening to any required input signal without interrupting the main mix, for making adjust-
ments or tracing problems. When SOLO is pressed anywhere on the console, the Control
Room outputs automatically switch from monitoring the Mix Outputs.
q PEAKLED
This LED will light when the signal level approaches clipping at any of the three monitored
points:
a) PRE-EQ
b) POST-EQ
c) POST-FADE
