INTRODUCTION
Thank you for purchasing this Soundcraft Si PERFORMER mixer. The Si PERFORMER is an
incredibly versatile but simple to use digital console optimized for live sound environments
or other situations where fast and clear access to any control or parameter is needed.
Si PERFORMER breaks new ground and is the rst DMX512-ready professional live
sound audio mixing console capable of controlling DMX512 compatible lighting xtures;
functionality will be released alongside software updates to the main console feature set.
Along with many new technologies and features the Si PERFORMER borrows much from its
predecessors the Soundcraft Si1, Si2 & Si3, Si Compact consoles and Soundcraft Vi series
ensuring high reliability, fantastic audio quality and a mature & comprehensive feature set.
Owning a Soundcraft console brings you the expertise and support of one of the industry’s
leading manufacturers, and the results of over three 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
Soundcraft Si PERFORMER is designed to be as easy to use as possible. We have spent
years researching the most efcient 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 recognized by millions to be the industry
standard because of its efciency.
The sonic qualities of our products are exemplary and some of the same designs used on
our most expensive consoles are employed in the Si PERFORMER, 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 Soundcraft Si PERFORMER 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 Soundcraft Si PERFORMER range 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 we ensure that the product meets the high demands
of the user.
NOTE: The packaging, in which your console arrived, forms part of the product and
must be retained for future use.

ADVICE FOR THOSE WHO PUSH THE BOUNDARIES
Although your new console will not output any sound until you feed it signals, it has the
capability to produce sounds which, when monitored through an amplier 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 nd 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.

WIRING UP
Mic Input
The MIC input accepts XLR-type connectors and is designed to suit a wide range
of BALANCED or UNBALANCED signals, whether from delicate vocals requiring
the best low-noise performance to drum kits to high level line sources.
Stereo Line Inputs
Accepts 3-pole 6.35mm (1/4") jacks, or 2-pole mono jacks which will
automatically ground the ‘cold’ input. Use these for input for sources such as
keyboards, drum machines, synths, CD players etc.
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 minimize interference
pick-up on the cable.
NOTE: The ring must be grounded if the source is unbalanced
AES Input:
This is a balanced 2-channel digital input using a single XLR wires as per the
balanced mic inputs. Although it is possible to use standard balanced audio
cable with AES signals it is recommended to use AES cable which has the correct
110R impedance.
DO NOT use UNBALANCED sources with the phantom power
switched on. The voltage on pins 2 & 3 of the XLR connector may
cause serious damage. BALANCED dynamic mics may normally be
used with phantom power switched on (contact your microphone
manufacturer for guidance)

Line Outputs
The 16 Line outputs are wired as shown and are fully balanced allowing long cable
runs to other equipment. If connecting to un-balanced destinations the Signal –
(cold) pin should be grounded.
AES Output:
This is a balanced 2-channel digital output using a single XLR wired as per the
balanced line outputs. Although it is possible to use standard balanced audio
cable with AES signals it is recommended to use AES cable which has the correct
110R impedance.
Headphones
The PHONES output is a 3-pole 6.35mm (1/4”) jack, wired as a stereo output
as shown, ideally for headphones of 32Ω or greater; 8Ω headphones are not
recommended. The headphone socket is found under the front edge, close to
fader 1.

DMX 512 OUT
DMX OUT is a 5-pin male XLR for connection to compatible devices; recommended
cable impedance is 120R. The maximum cable run from rst to last device is
1,200m (~3,900ft), although this may be shorter depending upon cable and
connector quality and local RF environment.
There should be no more than 32 devices connected to the bus without using an
active splitter and a 120R terminator is normally required on the last DMX device
however you should always refer to the manuals for your DMX devices for specic
details and requirements.

Soundcraft Si Performer User Guide 0912
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 microphones 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 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 signicantly 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 microphones, 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.
Warning!
Under NO circumstances must the AC power mains earth be
disconnected from the mains lead.

Soundcraft Si Performer User Guide 0912
The Assignable Channel Strip
(ACS) follows the currently
SELected channel or mix and
provides almost all of the
controls relating to the selected
channel or bus; it is broken
down in to small colour coded
sections making it easy to
identify control groups and
functions at a glance.
Unlike any other console in this class, there is a dedicated control for each
function therefore no ‘overlaying’ of controls is needed and each control has a
dedicated label and scale just as you would have found on an analogue mixer

AUDIO INTERROGATE
The Si PERFORMER offers a quick and convenient method for checking and in many cases
changing the status of many parameters, this is known as ‘interrogate’.
Example #1 – To check the status of the LR routing switch from inputs to the main LR bus:
a. Select a fader bank that includes inputs.
b. Press and hold the LR routing key.
c. The SELect keys on any channels routed to LR will light.
d. While holding the LR key you may toggle the status of the LR routing on any channels or
busses by pressing the SELect keys of the channels or buses you wish to include/exclude
from the routing.
Interrogate operates on the following audio functions whose status may then be toggled with
SELect key:
48v ON/OFF
Phase Reverse ON/OFF
HPF IN/OUT
GATE IN/OUT
COMPressor IN/OUT
EQ IN/OUT
LR routing ON/OFF
MONO routing ON/OFF
NOTE: When entering interrogate mode the status of the switch you press and hold is
not changed.
VCA & MUTE INTERROGATE
Interrogate may be used with the VCA and MUTE keys, pressing and holding either of these
keys will ip the channel LCD names and backlight colour as appropriate and indicate to
which VCA or MUTE master(s) the channel or bus is a slave.
