SIGNATURE LEGACY
The Signature Series consoles bring musicality, creativity, and technical excellence together, thanks
not only to new technology and ideas, but also to a 40-year legacy of producing outstanding perfor-
mance tools. This console incorporate classic analogue designs, approved by Engineers.
Ghost® pre-amps
The Soundcraft Ghost console's ProMic
mic pre-amp is known for it's ultra-low
noise and high headroom, making high
gain settings possible, without
compromising signal integrity.
Sapphyre British EQ
The Soundcraft Sapphyre console Asym-
metric EQ makes both creative and func-
tional tonal shaping of your signal simple
and intuitive. The EQ behaves differently
in cut and boost, making tonal adjust-
ments musical, and focusing cuts where
they are needed. See section 1.0.2 for
more detail.
GB Routing
The GB Console legacy is in Signature's
signal routing. There is pre/post switching
forallauxbusses,plusflexibleroutingand
dedicated outputs for sub-groups.

SAPPHYRE EQ
Soundcraft Sapphyre Asymmetric EQ
TheSoundcraftSignatureconsoleusesaspecialAsymmetricEQfirstdevelopedfortherenowned
Soundcraft Sapphyre console. This EQ makes both creative and functional tonal shaping of your signal
simple and intuitive - an EQ that works the way music does.
The shelving bands of the EQ (LF and HF) use a slight boost at the EQ's frequency when cutting,
and a slight cut when boosting.
For low frequencies, a slight cut when boosting prevents muddiness in he signal, while a slight boost when
cutting enables you to clean up the low end without losing precious `punch' and `body' of the signal. For the
HF shelf, a slight cut when boosting prevents harsh resonance at the EQ's frequency, and a slight boost
before a cut can help maintain brightness while reducing HF.
The mid-bands (bell-shape) have a wide bandwidth (low Q) when boosting, and a narrower band-
width (high Q) when cutting.
The wide boost prevents prevent harsh resonances and tonal-changes that allow for a more pleasing and
musical EQ boost. The Narrow cut focuses on problematic frequencies, for getting rid of resonances, rings,
hums, and preventing feedback. If this was too wide you could remove too much `body', creating a thin
sound.

GETTING STARTED - AN INTRODUCTION TO THIS MANUAL
Anyone with minimal audio experience should be able to operate the Soundcraft Signature console
without reading too much of this manual, though we do recommend you take the time to go through it.
An excellent place to start would be the feature list on the introductory page (section 1.0), which will
familiarise you with all of the main possibilities, facilities, and functions.
Please note: Most of the illustrations in this
manual are based on the Signature 22 console.
Where there are differences between operation
of Signature 16, 22, and 22MTK, it is noted in
the relevant section.

2.0: INTRODUCTION TO THIS MANUAL
16, 22, 22MTK User Manual 2.1: CONSOLE INTRO
GETTING STARTED > INTRODUCTION TO MIXING CONSOLES
The main function of a mixing console is to combine different audio inputs and independently adjust the levels
of those contributions to the mix. With this very basic functionality you can control and balance any kind of audio
from a one-man-band to an orchestra.
Most mixers however (including the Signature Series) offer far more than that. A variety of features allow the
operator to shape the mix, and use routing options to provide the additional conveniences used in audio mixing
applications, such as external effects sends, stage monitoring outputs, independent headphone monitoring, and
digital inputs and outputs.
Mix Faders
Faders make it easy to see and adjust relative levels. They allow you to visualise the mix.
Input Choice
All different microphones and instruments are catered for with mic, line, and Hi-Z input types / selections, in-
cluding 48V phantom power for powered (condenser / capacitor) microphones. The gain control allows you to
optimise the input level.
Equalisation
Examplesincludethehighpassfilteronaninputtoreduceunwantedlowfrequencies,orthethree-bandEQ
(Equaliser) used for tonal `shaping' of the source.
Dynamic Processing
This is audio processing that affects amplitude (volume). The Signature console includes a Limiter on selected
channels, which will prevent the input signal going too high, which would in turn cause distortion.
Output options
As well as mixing all the input (source) channel into one Master Stereo output, you can send particular
channels into additional group outputs, or create several different aux (auxiliary) mixes of all channels to send
to an FX (Effects) processor or stage monitor, for example. The headphone output allows the operator to listen
to the whole Main Mix, or to a selection of channels via the Solo System.
Solo / Monitor System
The solo system allows you to listen only to particular channels or busses through the headphones output, so
you can focus on a particular source without changing the mix.
Internal FX
FX (Effects) processing such as reverb, delay, chorus, phasing, and so on can be incorporated into a mixing
console so that you don't have to invest in `outboard' equipment or use up valuable physical inputs and outputs.
The Signature's Lexicon FX processing can be applied in a controlled manner by using the Auxiliary 3/FX mix
and the dedicated stereo FX return channel.
Digital inputs and outputs.
Digital I/O is necessary to work with digital audio systems and computer-based Digital Audio Workstations.
The Signature series uses a USB interface for either 2-channel input/output (main or Aux 1-2 output), or for
multitrack input and output (MTK versions) with the USB inputs able to individually replace the input channel
sourceforaflexible`tapereturn'path.Forexample,theMTKfunctionalitycoulduseDAWplug-insasinsert
processing on selected input channels, or you could do a sound check with a dry recording of the band from a
previous gig... There are lots of ways to use this feature.

INPUTS & OUTPUTS > CONSOLE INPUTS
Console inputs can be used for a wide variety of sources. For best results always use the appropriate
input connection.
Mic Input - XLR
Input connection for microphones using standard XLR connection (Pin-2 hot)
When using condenser microphones, you can switch on 48V phantom power for these connections on the right
hand side of the console (the 48V button). It's best practise not to use phantom power with unbalanced or instru-
ment inputs, switching it off BEFORE unplugging and switching it on AFTER plugging in.
Line Input - Jack
Balanced line-level connection for all other inputs
A Hi-Z option is provided on selected channels, required by high output impedance sources, such as guitar
pick-ups (when connecting a guitar directly to the mixer).
Line Input - RCA
Unbalanced input for line level/consumer playback equipment and instruments

The console outputs offer a range of connection options depending on the application. Always
consider carefully the best output and routing strategy for your particular application.
MST L / MST R
Master Left and Right outputs, XLR connectors
These are impedance-balanced line level outputs (pin 2 signal). The XLR outputs are labelled 'MST L' and MST R',
which refers to Master Left and right outputs of the main stereo output. These should be connected to the input
of your amplifier, PA system, recorder, or similar.
AUX 1 / AUX 2 / AUX 3
Auxiliary output connectors - quarter-inch Jack
Line level output, TRS Jack. Impedance balanced.
HEADPHONES
Stereo headphone output - quarter-inch TRS Jack
The headphone signal is always the Master Stereo Output unless a Solo (PFL or AFL) is activated. In that case, the
headphone output is switched to the Solo Bus.

USB - Signature 16 and 22
USB data connection for audio input and output
USB input (USB channels 1 and 2) are summed with the RCA input signal on the highest-numbered stereo input
channel. The USB output is taken either from the Master Stereo output (MST) or the Aux 1-2 output (according to
selector switch next to USB connector). For more detail on this feature, please see section 7.
USB - Signature 22MTK (24 Track I/O)
USB data connection for audio input and output
The Signature MTK (MultiTrack) console uses the USB port to send post gain direct outputs from all input chan-
nels and optionally return those channels to the same input channel. This is, in effect, a USB insert or tape return
path for all input channels. USB output channels 23 and 24 are used for the Master Stereo (MST) output. For
more detail, please see section 7.
USB POWER
For attaching powered/chargeable USB peripherals
Examples include a USB-powered LED lamp, or a mobile phone. Not for data. This connection supplies USB 2.0
compliant 500mA. Devices that draw more than this amount should not be connected.
FOOTSWITCH
Connect a TRS foot switch for FX Mute functionality
Various foot switches are available, depending on the specific functionality you require. Connecting Tip and Ring
('Make') will mute the internal FX.

CONSOLE ROUTING > STEREO INPUT
There are two types of
Stereo input channel.
The lower-numbered
stereo input channels
have microphone
inputs and Jack inputs
and can be used as
mono input channels
(odd-numbered input) if
required. On Signature
22 and 22MTK Stereo
channel 19/20 doesn't
have a mic input.
The highest-numbered
Stereo input is a sum of
the line level R inputs
and the stereo USB
input (if present). This
is the playback channel
and works with the
INTERVAL MUTE
function for convenient
2-track playback
functionality.
Stereo input channels
have the same routing
options as mono input
channels. Aux bus
contributions from
stereo channels are
made from a sum of the
left and right signals.
Group bus contribu-
tions are balanced /
panned left and right

odd-numbered and
even-numbered group
respectively. In other
words - fully left would
be fully Group 1 or

16, 22, 22MTK User Manual 4.3: FX RETURN
CONSOLE ROUTING > FX RETURN
An FX Return channel is a special stereo input channel is fed from the output of the internal FX
processor.
An FX Return channel can contribute to any Aux bus (EXCEPT its own source), and to the Master
and Group busses - as per mono and stereo input channels. Signature 22 and 22MTK consoles have
two FX Return channels as those consoles have two internal FX processors.
4.3: FX RETURN ROUTING
16, 22, 22MTK User Manual 4.4: AUX MASTER
CONSOLE ROUTING > AUX MASTER
Aux busses sent directly out of the corresponding Aux outputs, and are globally switchable between
pre- and post-fade sources. That is, an Aux mix that is taken `pre-fade' (before the input channel
fader) is not affected by the input channel fader levels. An Aux mix taken `post-fade' (after the input
channel fader) will be based on the fader levels of the contributing input channels.
The Playback Channel (highest-numbered stereo input) Aux 1 and 2 sends can be individually
switched post-fader. This is useful where, for example, the Aux 1/2 outputs are being used for pre-
fade stage monitors. By switching the `playback' (incidental of interval music for example) to post-fad-
er, musicians will be able to hear the playback music when it is faded up, and still allow the console
operator to hear the channel on PFL without it being heard in a monitor.
Aux Masters can contribute to the Solo bus (AFL). See section 6 for more details.
4.4: AUX MASTER ROUTING
16, 22, 22MTK User Manual 4.5: GROUP MASTER
CONSOLE ROUTING > GROUP MASTER
The Group Master Outputs are derived from the post fade, post pan sum of input channels routed to
the corresponding Group busses (1-2 and 3-4 switches).
The Group Masters can contribute to the Master Left/Right Bus.
A useful example of this in practise might be where a group of related input channels (drum mics,
backing singers, and so on) are mixed relative to each other, then routed to GRP 1-2 (but not to
MST). If the Group Masters are then in turn routed to the Master Left/Right output you can adjust the
level of the whole group within the main mix by using the Group 1 and 2 faders.

16, 22, 22MTK User Manual 5.0: CHANNEL CONTROLS
CHANNEL CONTROLS
There are three types of Signature console input channels: Mono Input, Stereo Input, and FX Return.
The output channel types are the Auxiliary (Aux) Master Outputs, the Master Stereo Outputs, and the
Group (GRP) Master Outputs.
5.0: CHANNEL CONTROL
16, 22, 22MTK User Manual 5.1: INPUT CONTROLS

PHANTOM POWER 48V
Apply a DC voltage of 48V to all microphone inputs
This button is found on the right of the console near the headphones level control, not on the channel strip.
With phantom power on, you should use only balanced sources in the console's XLR microphone inputs. Balanced
dynamic microphones (for example) will be unaffected. Condenser microphones normally require phantom
power, and it is sometimes used to power active circuitry in other devices, such as DI boxes.
LIMITER
Activate the input limiter
The Signature's dbx® Limiters uses fixed time constants and threshold with high-ratio compression to tame signal
peaks and prevent audio clipping. You can purposefully `drive' the limiter by turning up the Gain until the limiter
LED lights. The Limiter button LED lights when gain reduction is applied.
GAIN REDUCTION LED
Lights when the Limiter is applying gain reduction
When the Limiter applies gain reduction, the LED will light. The LED's light will become more intense as more gain
reduction is applied.
HI-Z
Switch the line (Jack) input to 'Hi-Z' (high impedance) mode
Activating Hi-Z presents a much higher load impedance to the source in order to work more effectively with
high-impedance sources such as guitar, bass, and other instrument pick-ups that are connected directly to the
console. Using the `standard Z' mode on high impedance sources will have a detrimental effect on the high
frequency response.
GAIN
Adjust the input gain
The Gain range is 10dB to 60dB. It is advisable to listen and/or to check the channel Peak LED while increasing
gain to avoid distortion due to clipping. Before plugging in a new source, turn the Gain down to avoid sudden
loud noises.

HPF 100Hz
Activate the High Pass Filter
The High Pass Filter (HPF) is an 18dB/Octave filter that attenuates frequencies below 100Hz. This can be useful for
filtering out low 'rumble' from microphones affected by extremely low traffic noise, air flow, and so on.
USB RTN (22MTK only)
Enable the USB Return function
When active, the audio on USB channel 'n' (where 'n' is the console channel number) will replace the analogue
inputs post-gain (pre HPF / EQ) and the analogue audio path will be broken. Please see section 7 for more details.
HF
Adjusttheboost/attenuationofthehighfrequencyshelvingfilter
The HF shelving filter has a fixed frequency of 12kHz. Frequencies above this will be boosted or attenuated
depending on the control setting. With this Sapphyre asymmetric EQ, there is a small boost at the filter frequency
on cut and a small cut on boost. See section 1.02 for more detail.
HMF/LMF Frequency
AdjustthecentrefrequenciesoftheHigh-MidandLow-Midbell-typefilters
The Signature HMF and LMF EQ bands are bell-type, semi-parametric filters. This control adjusts the centre fre-
quency of those bell shapes between 400Hz (approximately G3) and 8kHz (approximately B8) for the HMF Filter,
and between 80Hz (approximately D#1) and 2kHz (approximately B6) for the LMF filter.
HMF/LMF Level
Adjusttheboost/attenuationoftheHigh-andLow-Midbell-typefilters
This will adjust the gain or attenuation of the audio band, centred according to the corresponding frequency con-
trols. This is an asymmetric EQ, so boost has a wide bandwidth (low Q), and cut has a narrow bandwidth (High
Q). See section 1.0.2 for more detail.

LF Level
Adjusttheboost/attenuationofthelowfrequencyshelvingfilter
The LF shelving filter has a fixed frequency of 60Hz. Frequencies below this will be boosted or attenuated
depending on the control setting. With this Sapphyre asymmetric EQ, there is a small boost at the filter frequency
on cut and a small cut on boost. See section 1.02 for more detail.
AUX1 / AUX2 / AUX3
Adjust the level of this channel's contribution to the Aux 1, Aux 2, and Aux 3 busses
An Auxiliary bus is a summed 'alternate' mix of any contributing channels. In other words - for example - the
console's Aux 1 output will consist of all channels whose Aux 1 controls are greater than -infinity (off) - mixed pro-
portionally according to the relative levels of all the Aux 1 controls. You could use this for a stage monitor mix, or a
'send' to an external FX processor, for example. The source for the Auxiliary bus send can be either post-fader or
pre-fade, as set by the button in the Auxiliary Masters section.
AUX4/FX, AUX5/FX
Adjust the level of this channel's contribution both to the Aux bus (as per Aux 1, 2, and 3), and the
Internal FX processor.
Signature 22 and 22MTX consoles have two internal FX processors and therefore have an additional Aux/FX send
(Aux5/FX). The Aux 4 bus and the FX bus (also Aux 5 / FX 2 busses for signature 22 / 22MTK) are independent,
but share the same Send level. The source for an FX bus send is always post-fader so that a source's contribution
to an effect is proportional to its contribution to the mix. The Aux source can be switched Pre or post (as per
normal Aux send).
PAN
Adjust the signal's stereo position and group routing.
Pan determines both the signal's position on the Master (MST) Stereo output and the amount of signal sent to
odd-numbered (left) and even-numbered (right) group outputs. For example, with a channel's 1-2 and MST
routing switches engaged, turning the control right puts more of the signal in the right (MST) channel AND
the Group 2 bus. Turning the control fully right will route the signal fully to the right-hand master channel AND the
Group 2 bus.
MUTE
Mute the signal
This is a pre-fade mute and so does not affect the USB send on the Signature 22MTK console. However, it will
mute all Aux bus contributions, as well as Master Stereo and Group contributions. When a channel is muted, the
Peak & Mute LED will light.
5.1.1: MONO INPUT CONTROLS
16, 22, 22MTK User Manual 5.1.1: MONO INPUT CONTROLS
CHANNEL CONTROLS > MONO INPUT CONTROLS
PEAK & MUTE LED
Lights when signal reaches peak level or shows that the channel is muted
The Peak LED is a warning light to let you know when the signal is nearing maximum headroom. The peak
detection source is taken from a number of key points in the signal path (see section 4.1) where gain is used: After
the High Pass Filter, post EQ, and post Fade. If a signal is amplified past the limits of the console's headroom, then
'clipping' (noise) will occur.
PFL
Route the signal to the Solo bus and mute any channels not routed to the Solo bus
With a PFL enabled, the headphone output will switch to the Solo Bus. Please see section 6 for more detail.
FADER
Adjust signal level
The Fader adjusts level between -infinity (no signal) to +10dB. The 0dB line indicates unity (no level change).
Faders are the primary mixing tools during performance; the relative levels of the input channel faders across the
co
