General Precautions
Avoid storing or using the mixing console in conditions of excessive heat or cold, or in positions where it is
likely to be subject to vibration, dust or moisture. Do not use any liquids to clean the fascia of the unit: a
soft dry cloth is ideal.
Avoid using the console close to strong sources of electromagnetic radiation (e.g. video monitors, high-
power electric cabling): this may cause degradation of the audio quality due to induced voltages in con-
necting leads and chassis.
Caution! In all cases, refer servicing to qualied personnel.
Handling and Transport
The console is supplied in a strong carton. If it is necessary to move it any distance after installation it is
recommended that this packing is used to protect it. Be sure to disconnect all cabling before moving. If
the console is to be regularly moved we recommend that it is installed in a foam lined ightcase. At all
times avoid applying excessive force to any knobs, switches or connectors.
Power Cable
Always use the power supply cable supplied with the mixer: the use of alternative cables may cause dam-
age and voids the warranty.
W a r n i n g ! In the event of an electrical storm, or large mains voltage uctuations, immediately
switch off the mixer and unplug from the mains.
Signal Levels
It is important to supply the correct input levels to the console, otherwise signal to noise ratio or distortion
performance may be degraded; and in extreme cases, damage to the internal) circuitry may result. Like-
wise, on all balanced inputs avoid sources with large common mode DC, AC or RF voltages, as these will
reduce the available signal range on the inputs. Note that OdBu =0.775V RMS.
Refer to the Specications section for details of input and output levels.
MAINS INSTALLATION
General Wiring Procedures
To take full advantage of the excellent signal to noise ratio and low distortion of Soundcraft consoles, care
must be taken to ensure that incorrect installation and wiring does not degrade the performance of the
desk. Hum, buzz, instability and Radio Frequency interference can usually be traced to earth loops and
inferior earthing systems. In some areas, especially heavily industrial areas, the incoming mains earth will
not be adequate and a separate technical earth for all the audio equipment must be supplied. However,
check with your local electricity supply company to ensure that safety regulations are not infringed or
negated.
The successful, hum free, installation of a system requires forethought, and the establishment of a set of
ground rules, which must be consistently adhered to at all stages of installation.
INSTALLATION

Page 1 - 6 Soundcraft® Si Series User Guide
Initial Wiring Considerations
For optimum performance, it is essential for the earthing system to be clean and noise free, as all signals
are referenced to this earth. A central point should be decided on for the main earth point system, and all
earths should be ‘star fed’ from this point. It is common electrical practice to `daisy chain’ the earths to
all electrical outlets but this method is unsuitable for audio installations. The preferred method is to run an
individual earth wire from each outlet, back to the system star point to provide a safety earth screen refer-
ence for each piece of equipment.A separate earth wire should also be run from each equipment rack and
area, to the star point. This may or may not be used depending on circumstances, but it is easier to install
in the rst place, than later when problems arise.The location of the star point should be a convenient,
easily accessible place, preferably at the rear of the console or in the main equipment rack.
Install separate ‘clean’ and ‘dirty’ mains outlets, wired individually back to the incoming mains distribution
box. Use the ‘clean’ supply for all audio equipment and the `dirty’ supply for all lighting, etc. Never mix the
two systems.
If necessary, to provide sufcient isolation from mains borne interference, install an isolating transformer.
This should be provided with a Faraday Shield which must be connected with earth.
Never locate the incoming mains distribution box near audio equipment, especially tape recorders, which
are very sensitive to electro-magnetic elds.
Ensure that all equipment racks are connected to earth, via a separate wire back to the star point.
Equipment which has unbalanced inputs and outputs may need to be isolated from the rack to prevent
earth loops.
Audio Wiring
Having provided all equipment with power and earthing connections, consideration must be given to the
method of providing audio interconnection and adequate screening of those interconnections. This must
be done in a logical sequence to avoid problems and assist in the localisation of problem equipment.
Connect the FOH or Monitor system to the console and check for any hum, buzz, or RFI. Only when you are
satised with the quietness of the console and the PA system should you proceed with the next step.
Connect stereo or multitracktape recorders, FX and foldback sends one at a time, checking and isolating
any connection which degrades performance.
Connect all other peripheral devices.
Connect all microphone lines.
By following this sequence much time and future trouble will be saved, and the result will be a quiet,
stable system.
Shielding
Audio equipment is supplied with a variety of input and output congurations, which must be taken into
consideration when deciding where the screen connections should be made. There are three sources of
unwanted signal being impressed on the screen, which are as follows:
Extraneous electrostatic or electromagnetic elds.
Noise and interference on the earth line.
Capacitive coupling between the screen and signal wires.
To minimise the adverse affects of the unwanted coupling to the signal wires, it is important that the
screen is connected at one end only, i.e. the screen must not carry any signal) current. Any signal) on the
wires within the screen will be capacitively coupled to the screen. This current will ultimately be returned to
the source of the signal, either directly, if the screen is connected at the signal source end, or indirectly via
the earthing system, if the signal is connected at the signal destination end. The indirect connection will
cause an increase in high frequency cross-talk, and should be avoided wherever possible.
Therefore, in general, always connect the shield only at the signal source end. In high RF areas, the screen
can also be connected to earth via a 0.01 mF capacitor. This will present a short circuit at RF frequencies,
thus lowering the effective shield impedance to ground. However, at low audio frequencies the reactance of
the capacitor will be sufciently high not to cause an earth loop problem.

Page 1 - 7Soundcraft® Si Series User Guide
WORKING SAFELY WITH SOUND
Although your new console will not make any noise until you feed it signals, it has the capability to pro-
duce sounds which when monitored through a PA system or headphones can damage hearing over time.
The table below is taken from the Occupational Safety & Health Administration directive on Occupational
noise exposure (1926.52):
PERMISSABLE NOISE EXPOSURE
DURATION PER DAY, HOURS SOUND LEVEL dBA SLOW RESPONSE
8 90
6 92
4 95
3 97
2 100
1.5 102
1 105
0.5 110
<0.25 115
Conforming to this directive will minimise the risk of hearing damage caused by long listening periods. A
simple rule to follow is the longer you listen the lower the average volume should be.
Please take care when working with your audio - if you are manipulating controls which you don’t under-
stand (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 results.
Recommended headphone impedance is 50-600 ohms.
Points to Remember
In all cases, use good quality twin screened audio cable. Check for instability at the output.
Always connect both conductors at both ends, and ensure that the screen is only connected at one end.
Do not disconnect the mains earth from each piece of equipment. This is needed to provide both safety
and screen returns to the system star point.
Equipment which has balanced inputs and outputs may need to be electrically isolated from the equip-
ment rack and/or other equipment, to avoid earth loops.
It is important to remember that all equipment which is connected to the mains is a potential source of
hum and interference and may radiate both electrostatic or electromagnetic radiation. In addition, the
mains will also act as a carrier for many forms of RF interference generated by electric motors, air-condi-
tioning units, thyristor light dimmers etc. Unless the earth system is clean, all attempts to improve hum
noise levels will be futile. In extreme cases there will be no alternative but to provide a completely sepa-
rate and independent `technical earth’ to replace the incoming ‘noisy earth’. However, always consult your
local electricity supply authority to ensure that safety regulations are not being infringed.

POWER SUPPLY
The console is equipped as standard with one power supply unit. A second PSU may optionally be tted.
SWITCHING ON
The POWER ON button on the front of the console is used to turn the console ON
and OFF
When AC mains power is connected to the PSU, and its switch is set to on, the
POWER ON button will slowly ash green (and the blue logos on the sides of the
console will be illuminated).
Pressing the POWER ON button while it is slowly ashing green will activate the boot-
up procedure of the console. The POWER button will then stop ashing and remain
illuminated green. The touchscreen will display the progress of the boot-up.
If a second PSU is tted, and one of them malfunctions, or is switched off, the POWER button will illuminate
red instead of green. This applies only to the steady-state illumination when the console is powered-up.
SWITCHING OFF
Warning. Damage may be caused to the OLED displays on the console if switching off is not
carried out correctly. Do not turn the PSU switch off or disconnect it from the mains supply
until the following procedure has been followed:
Press and hold the illuminated POWER ON button for greater than 2 seconds. This will start the
power-down sequence. When the POWER ON button is ashing the mains may be disconnected.
Note: If your console has two PSUs for redundant operation it is permitted to switch one of the supplies off
and disconnect from the mains in order to hot-swap in a replacement PSU.
