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.

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)

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.

From Impedance-Balanced Output

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.

MIDI IN & OUT This is a standard 5-pin 1800 DIN connector conforming to the MIDI standard as shown.

Word Clock

75ohm BNC coaxial connector used to lock the Si EXPRESSION to other digital equipment.

HiQNet

Standard 100MB/s RJ45 connector used to connect the Si EXPRESSION to a LAN.

Soundcraft Si Expression User Guide V1.0 0213

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 Expression User Guide V1.0 0213

Assignable Channel Strip (ACS)

The Assignable Channel Strip (ACS) follows the currently SELected channel or bus 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 Any encoders or functions that are not available/appropriate for a given mode will be un-lit and have no function. Although the control surface has values marked against the encoders the absolute value of any encoder will be shown on the touch screen provided by the Function Focus feature.

The GAIN/TRIM encoder on the ACS functions as GAIN control when controlling a mic

amp and TRIM for a LINE source whenever the ACS is selected to an input
