Drawing on the heritage of Soundcraft’s
acclaimed Si Series digital live sound
mixers, the new Si Compact packs powerful
digital mixing facilities along with stunning
Lexicon® effects into a trio of small
footprint consoles available in 16, 24 or 32
mic/line input formats, with 4 stereo returns.
And for once, compact doesn’t mean
compromise. No layering of the audio
controls makes operation fast and simple,
and with 4 separate FX processors with
dedicated FX busses in addition to the main
mixes, and Graphic EQ for every bus, you’ll
never find yourself wishing you had more
processing power.

Legendary Soundcraft audio quality comes
courtesy of EMMA Lite, the same DSP
platform that has helped propel the Si Series
to industry standard status. Features like
dedicated FX busses, 16 line outputs plus
AES, an option card slot for MADI or other
connectivity, a Global Mode for instant
access to Pan, Gain and Filters, a colour
touchscreen interface and FaderGlow™
equip Si Compact for a range of live sound
mixing applications including bands,
theatres and houses of worship.

Now everyone gets to share in the success

nput Section

I

The Input section has 8-segment stereo metering controls for
phantom power and polarity reverse, gain/trim adjustment and
frequency setting for the high pass filter.

ccessories Tray

A

us Switches

B

Provides instant access to any bus mix, and
sets up the console for mixing straight to
the chosen bus. See TOTEM section (right).

Dynamics Section

The Dynamics section has controls
for the gate and compressor which
feature on every channel, with
compressors also available on all
busses providing full control over
side-chain filters, thresholds, attack,
release, gain, depth and ratio.

EQ Section

A four-band EQ section is provided on
every channel and on every bus
output, with two swept mid bands,
and shelving HF and LF sections.

Out Section

The Out section contains a Delay control (again for
all inputs and outputs), and a Pan control, plus
Stereo and Mono mix assignment.

USB

Desk settings and snapshots can be stored
for later recall onto a USB memory stick
through this USB port.

Colour Touch Screen

Used primarily for setup, show control and
naming, the colour touch screen is
secondary to mixing. Here, you can assign
inserts, patch channels and setup
monitoring, etc.

TOTEM™
The one-touch easy mix

Si Compact features TOTEM™, a super-easy way
to get mixing. Depending on which busses you
have selected, (for example FX bus 1) one touch
of a TOTEM button will:

• Clear all current Solos

• Put input faders into sends on faders mode,
lighting fader glow accordingly

• Place the Bus master or FX return onto the

ONO/Sel fader

M

• Solo the appropriate bus master or FX Return
channel

• Assign the central control section to the bus
output or FX retrun

of Soundcraft digital live sound mixing

Encoders

Each channel has a multifunction rotary encoder, which acts in one of the
following modes when engaged by the corresponding master switch:
Gain: controls channel gain.

Meters

Metering provided for every
active channel or bus,
showing level, gain
reduction and gate closed.

On

The channel On key turns on
the channel so that it
becomes active. The switch is
lit red if the channel is muted
by a mute group or similar.

GB30 Mic Preamps

The mic preamps on the Si Compact
follow in the Soundcraft tradition of
exemplary performance, winning
worldwide acclaim for the
transparency, high headroom and
overload characteristics. These
preamps use the well-established
GB30 topology which has been used
on countless Soundcraft products.

Filt: adjusts the frequency of the high-pass filter
Pan: adjusts the signal in the stereo mix. When sending channels to a
stereo bus, this acts as a Pan to Bus control.

Select

Touch Select to bring a channel
to the central control section
for adjustment of gains, EQ,
dynamics, pan and delay.

FaderGlow™

Developed for Soundcraft’s acclaimed Vi Series
consoles, FaderGlowTMilluminates the fader
according to the operating mode it is in. Amber
shows pre-fade Aux sends, green for post-fade sends,
blue for FX sends, red for GEQ, white for stereo
channels, etc. The Follow (sends on faders) method
allows you to control send levels directly via the
faders, such as Aux sends, Matrix sends, FX sends.

Lexicon®FX

Four integral Lexicon stereo effects engines provide more than 20
preset effects, which are controlled via rotary encoders and the
touch screen. These effects may be assigned to any bus or input
channel, and the effects returns are independent of the channel
inputs. Unlike some other consoles in this class, users may adjust
parameters of the FX and store their own presets for later use.

Mute Groups

Four mute groups allow you
to control groups of channels
as one, with a single press of
the mute master.

GEQ

Selecting GEQ brings the graphic equaliser onto the
input faders, each fader controlling one frequency.
The natural feel of a centre-detent is reproduced
nicely by the Si Compact. GEQ LO selects the lower
half of the EQ from 31Hz to 630Hz, GEQ HI the upper
half from 800Hz to 16kHz, each fader being labelled
and scaled accordingly. GEQ is available for every bus
output.

Snapshot Control

The Si Compact incorporates a simple
cue/snapshot system. Over 1000
cues may be stored and recalled
through a simple combination of
buttons and colour touch screen.

EMMA Lite

At the heart of the Si Compact is
the EMMA Lite processor/DSP
engine, a derivative of that used on
the successful Si Series.
You’ll never run out of DSP,
even if you have all the
FX running, graphic EQs
on all outputs, delays on
inputs and dynamics on
inputs and outputs.
