User Manual 2.3: FADERGLOW GETTING STARTED > FADERGLOW Soundcraft FaderGlow™ (Pat. Pend.) is a unique feature that gives the user an additional level of status indication, and can significantly reduce operating errors. Several different functions can be assigned to the console faders, so it can be easy to lose track of which function is currently being controlled, especially when grabbing a fader in a hurry.
User Manual 3.0 ASSIGNABLE CONTROLS ASSIGNABLE CONTROLS At the heart of the Expression is a group of assignable controls that make the console easier and faster to navigate and operate. Assignable controls work by changing the function of sections of the console surface. In this way, a single control can do several jobs, depending on the mode the console is working in.
3.1 FADER LAYERS User Manual ASSIGNABLE CONTROLS > FADER LAYERS The are four main Fader Layers on the Expression console, selected by the FADERS button (A, B, C, and D) group to the right of the Control Channels. The additional buttons in this group assign Graphic EQ bands across the faders for convenient control. Each layer is made up of a number of Control Channel assignments.
User Manual 3.2 CONTROL CHANNELS ASSIGNABLE CONTROLS > CONTROL CHANNELS A Control Channel is an assignable Channel Strip for DSP Channels, with Encoder, Fader, indicators, plus ON, SOLO, and SEL buttons. The SEL button is used to focus the Assignable Channel Strip (ACS) on that channel. The DSP channel controlled by a Control Channel is determined by the current Fader Layer (FADERS button group) and assignment (FADER SETUP Touch Screen menu).
User Manual 3.2.1 CONTROL CHANNEL ASSIGNMENT CONTROL CHANNELS > ASSIGNMENT Control Channel Assignment is accessed via the FADER SETUP button in the Touch Screen Main Menu. Select the Control channel using the Fader Layer and SEL buttons in the usual way - the current Fader Bank and Slot Number cannot be edited in the FADER SETUP menu.

Please see section 10 for more details. 6.
User Manual 7.0: DSP ELEMENTS DSP CHANNEL ELEMENTS Input and output (Bus Master) DSP channels share many common DSP processing elements and controls via the Control Channel and Assignable Control Section (ACS). This chapter explains those elements and their controls. Please note, some elements will not be available (will be unlit and inactive) on certain channel types (Master Output Channels have no Gate section, for example). 7.
User Manual 7.1: FUNCTION FOCUS DSP ELEMENTS > FUNCTION FOCUS Function Focus allows pinpoint adjustment of any controls and settings by automatically detailing the value of both the control you are currently adjusting and any other controls in its group, plus the channel name and alternate units for the same control. For example, DELAY is illustrated in ms (milliseconds), feet, and meters, while EQ filter ‘Q’ is shown as both Q and bandwidth (octaves).
User Manual 7.2: ACS ELEMENTS DSP ELEMENTS > ACS ELEMENTS The Assignable Channel Strip (ACS) follows the currently selected DSP Channel and provides almost all of the controls relating to that. It is broken down in to small colour coded sections making it easy to identify control groups and functions at a glance.
7.2.1: ACS INPUT SECTION User Manual DSP ELEMENTS > ACS > INPUT The input section mainly provides the features required for input channels such as phantom power and mic/line level. Metering is applicable to all DSP Channel types, and HPF (High Pass Filter) is available in Auxiliary Mix master channels. Metering Signal level in channel shown as dBfs Stereo channels use both L and R bargraphs, mono channels use the L/MONO bargraph.
7.2.1: ACS INPUT SECTION User Manual DSP ELEMENTS > ACS > INPUT Phase Invert Invert signal phase (180 degrees). Pressing and holding the key will activate Interrogate mode for this function (see Mix Features 8.3). GAIN/TRIM Adjust mic gain or line trim for input channels. The control changes its function depending on the selelcted input. Mic Gain (-5dB - +58dB) is applied in the analogue domain, before analogue-to-digital conversion. It is only applicable to Microphone inputs.
7.2.2: ACS GATE SECTION User Manual DSP ELEMENTS > ACS > GATE A Gate is a threshold-driven gain reduction process normally used to attenuate a signal when its level falls below the Threshold. Setting the Threshold just above a noise floor or background noise, for example, will allow the Gate to attenuate the source during periods when the main input (voice, instrument etc) is silent. This gate includes a Sidechain Filter section.
7.2.2: ACS GATE SECTION User Manual DSP ELEMENTS > ACS > GATE DEPTH Adjust the Depth value of the Gate The amount of attenuation applied when the gate is closed. THRESHOLD Adjust the threshold of the Gate The signal level of the sidechain at which the gate is activated. S/C LPF Adjust the Sidechain Low Pass Filter This filter cuts high frequencies from the sidechain signal, limiting the frequency range of the signal that is ‘tested’ by the threshold setting.
7.2.3: ACS COMPRESSOR SECTION User Manual DSP ELEMENTS > ACS > COMPRESSOR A compressor is a threshold driven process used to reduce the dynamic range of a signal by applying gain reduction when the signal level exceeds the threshold and applying ‘make-up gain’ to keep the overall level consistent. You can use compression to increase the apparent loudness of a signal without increasing the peak level, or to control overly dynamic sources.
7.2.3: ACS COMPRESSOR SECTION User Manual DSP ELEMENTS > ACS > COMPRESSOR GAIN Adjust the make-up gain of the Compressor Gain applied after the compressor to account for level lost in compression. THRESHOLD Adjust the Threshold level of the compressor When the signal exceeds the threshold, it will be attenuated according to the ratio setting.
User Manual 7.2.4: ACS EQUALISER SECTION DSP ELEMENTS > ACS > EQUALISER The channel EQ (Equaliser) section is used for sculpting the tonal (frequency-based) balance of the signal. The expression EQ is a four-band type with two (Hi and Lo) Shelving filters, and two (Hi Mid and Lo Mid) fully parametric ‘bell’ filters. HF Level Adjust the boost/attenuation of the HF shelving filter. HF FREQ Adjust the centre frequency of the HF shelving filter.
7.2.4: ACS EQUALISER SECTION User Manual DSP ELEMENTS > ACS > EQUALISER HI MID Level Adjust the boost/attenuation of the HI MID filter. HI MID FREQ Adjust the centre frequency of the HI MID filter. Frequencies above and below this, within the bounds of the Q setting will be affected by the HI MID level control. That is, Q effectively sets the ‘width’ (bandwidth) of the filter’s bell shape and FREQ sets the frequency at the centre of the bell shape.
User Manual 7.2.4: ACS EQUALISER SECTION DSP ELEMENTS > ACS > EQUALISER LO MID Q Adjust the Q of the LO MID Filter Q is ‘magnification’ at resonance, and is inversely proportional to bandwidth. For an equaliser it is useful to think of it simply as a bandwidth control (the width of the ‘bell’ in the case of a bell-shaped filter). That is, the higher the Q, the lower the bandwidth - or the more ‘focussed’ the filter. Bandwidth (in octaves) is shown on the Touch Screen with the Function Focus feature.
User Manual 7.2.5: ACS OUTPUT SECTION DSP ELEMENTS > ACS > OUTPUT The outputs section contains features specific to the outputs of all channels. Delay and Pan (or balance) are applicable to all channel types, while LR and MONO routing is specific to input and Aux Mix master channels (not Matrix master channels). DELAY Adjust the delay applied to the output of this DSP channel. ACS units are milliseconds, though the Touch Screen will show feet and meters as well, with the Function Focus feature.
7.2.5: ACS OUTPUT SECTION User Manual DSP ELEMENTS > ACS > OUTPUT LR (Main Left Right Bus Routing) Route the selected chanel to the Main Left/Right Stereo Bus. Any channels routed to LR will be summed into the Main LR Master Output Channel, controlled by the L&R Control Channel. M (Main Mono Bus Routing) Route the selected chanel to the Main Mono Bus. Any channels routed to M will be summed (Mono) into the Main M/C Master Output Channel, controlled by the M Control Channel. 7.2.
User Manual 7.3: CONTROL CHANNEL DSP ELEMENTS > CONTROL CHANNEL Control channels contain the primary performance controls and indicators. Layers of Control Channels (assigned to various ‘actual’ channels) are selected using the FADERS (Fader Layers) button group. Control channel positions are assigned to channels using the Touch Screen FADER SETUP menu.
7.3: CONTROL CHANNEL User Manual DSP ELEMENTS > CONTROL CHANNEL Gate Closed (X) Indicates the selected channel's gate is closed. Gain Reduction Meter Indicates gain reduction for the selected channel. These are the three LEDs on the left side labelled 1, 5, 10 (dB of attentuation). Level Meter Indicates audio level for the selected channel - dBfs ON ON key function is dependant on the channel type and selected fader layer. Momentary / Latching behaviour available from software version 1.6 (see below).
7.3: CONTROL CHANNEL User Manual DSP ELEMENTS > CONTROL CHANNEL SOLO Press to Solo this DSP Channel (Input Channel, Mix Bus Master, Matrix Master). See section 8.4 for more information of the console’s Solo system. FADER Adjust signal level. Audio channel / Mix Master: Master level. FOLLOW MODE (tOTEM button selected): Send level form channel to selected bus. GEQ Mode (GEQ HI or GEQ LO FADERS button selected): GEQ band gain.
User Manual 7.4: GRAPHIC EQ (GEQ) DSP ELEMENTS > GRAPHIC EQ (GEQ) 28-Band Graphic Equalisers (GEQs) are available to all Output Masters on the console: Mix Bus, Matrix Bus, and Left/Rightand Mono Bus masters. All Output Masters can run GEQs simultaneously. When any output channel is selected, the GEQ LO and GEQ HI buttons (FADERS button group) will assign 14 bands to the Control Channel Faders, colour-coded with red FaderGlow. Faders are centre (0dB position) detented with in use as GEQ bands.
7.4: GRAPHIC EQ (GEQ) User Manual DSP ELEMENTS > GRAPHIC EQ (GEQ) When a band is moved from its zero position (0dB) the Control Channel ON button will light red to show that band is active. You can press a red ON button to ‘zero’ that band. A channel’s Graphic EQ setting does not affect the Touch Screen EQ response graphic (EQ Main Menu button). GEQ HI Press to assign the 14 'high' GEQ bands (800Hz - 16kHz) to the Control Channel Faders.
User Manual 8.0: MIX FEATURES MIX FEATURES Si Expression Mix Features include mix functions outside the normal audio signal path: Mute Groups, Copy and Paste, Interrogate, the Solo system, Monitoring, and the CLR and ALT + CLR facilities. 8.1: Mute Groups Set up groups of channels that can be muted with a single button press.

User Manual 8.2: COPY AND PASTE MIX FEATURES > COPY AND PASTE DSP Channel COPY-PASTE With a DSP channel (Input Channel or Mix/Matrix Bus Master) selected, COPY PASTE mode will display a version of the ACS (with GEQ for Bus Masters). By touching sections in this Touch Screen display you can remove individual sections from the paste operation. To select a single section only, touch and hold that section in the Touch Screen.
8.3: AUDIO INTERROGATE User Manual MIX FEATURES > AUDIO INTERROGATE Audio Interrogate is a powerful method of checking and changing a particular switch status across all channels on the currently selected fader layer. For example, you can check at a glance which channels are routed to the main LR mix bus and change that status rapidly for all visible channels.
User Manual 8.4: SOLO SYSTEM MIX FEATURES > SOLO SYSTEM Solo provides a way of monitoring and checking individual channels and groups of channels quickly by routing only the ‘soloed’ channels either to the monitoring system (normal operation) or to the main mix outputs (Solo In Place - SIP). There are two main types of SOLO: PFL (Pre Fade Listen) and AFL (After Fade Listen). The difference between the two is the ‘tap’ where the solo source is taken from in the selected channel - pre- or post-fader.
User Manual 8.4: SOLO SYSTEM MIX FEATURES > SOLO SYSTEM SOLO Press to solo the assigned channel Normal button behaviour is ‘latching’ (press on - press off). Press and hold a SOLO button for momentary (non-latching) behaviour. Press and hold an active SOLO button to use the Highlight feature, which highlights a soloed channel by attenuating other soloed channels. SOLO buttons light up orange when active.

User Manual 10: LEXICON FX LEXICON FX The console comes with four Lexicon FX processors, each with 29 available algorithms. Each FX unit has its own dedicated FX Send Bus, and stereo return path. Send Routing Every input channel can contribute to the FX 1-4 send busses, which correspond to the FX unit 1-4 inputs. Contributions are controlled in the same way as Mix bus contributions, via the FX 1 - 4 FADER FOLLOW (tOTEM) buttons, which assigns each channel’s contribution to the selected bus to its fader.
User Manual 10: LEXICON FX LEXICON FX Storage All Parameters from the four FX Units and for all FX Types are stored with console Snapshots. See chapter reference 9.2 for more on the Cuelist and Snapshots. Copy Paste Settings can be copied and pasted between processors using the console COPY PASTE function. Touch COPY PASTE in the Touch Screen Main Menu, then press the FX button in the Lexicon control group.
User Manual 10.1: REVERBS LEXICON FX > REVERBS Reverberation (or “reverb” for short) is the complex effect created by the way we perceive sound in an enclosed space. When sound waves encounter an object or boundary, they don’t just stop. Some of the sound is absorbed by the object, but most of the sound is reflected or is diffused. In an enclosed space, reverb is dependent on many features of that space, including the size, shape and the type of materials that line the walls.
User Manual 10.1: REVERBS LEXICON FX > REVERBS Room Reverb Room produces an excellent simulation of a very small room which is useful for dialogue and speech applications. Room is also practical when used judiciously for fattening up high energy signals like electric guitar amp recordings. Ambience Reverb Ambience is used to simulate the effect of a small or medium sized room without noticeable decay. It is often used for voice, guitar or percussion.
User Manual 10.1.1: REVERB PARAMETERS LEXICON FX > REVERBS > REVERB PARAMETERS PRE DLY - Pre Delay Adjust time delay between the source signal and the onset of reverberation. This control is not intended to precisely mimic the time delays in natural spaces, as the build-up of reverberation is gradual, and the initial time gap is usually relatively short. For the most natural effect, the Pre Delay values should be set in the range of 10-25 milliseconds.
User Manual 10.1.1: REVERB PARAMETERS LEXICON FX > REVERBS > REVERB PARAMETERS Shape Adjust the 'contour' of the reverberation envelope. With Shape all the way down, reverberation builds explosively, and decays quickly. As Shape is advanced, reverberation builds up more slowly and sustains for the time set by Spread.
User Manual 10.2: DELAYS LEXICON FX > DELAYS Delays repeat a sound a short time after it first occurs. Delay becomes echo when the output is fed back into the input (feedback). This turns a single repeat into a series of repeats, each a little softer than the last. Studio Delay The Studio Delay features up to 1 second of stereo delay and offers a built-in ducker that attenuates the delay output whenever signal is present at the input.
User Manual 10.2.1: DELAY PARAMETERS LEXICON FX > DELAYS > DELAY PARAMETERS Dly Time - Delay Time Controls the length of the delay time relative to Tempo. At the middle of its range, delay repeats are synchronous with the Tempo button; lower values create faster repeats, while higher values increase the time between repeats. Feedback Controls the number of delay repeats by feeding the delay output signal back into the delay input.
User Manual 10.2.1: DELAY PARAMETERS LEXICON FX > DELAYS > DELAY PARAMETERS Smear Ducking attenuation amount. Available only for Tape and Reverse Delays, this parameter controls the amount of “smear,” or signal degradation and frequency loss. The higher the setting, the more each delay repeat loses intelligibility compared to the original signal. Ratio - Tap Ratio Controls the Tap ratio of left and right outputs relative to the Delay time.
10.3: MISC FX User Manual LEXICON FX > MISC FX The MISC category provides primarily modulated and pitch-varying effects. Chorus Chorus creates a lush, full sound by combining two or more signals together where one is unaffected and the other signals vary in pitch very slightly over time. Chorus is commonly used to fatten up tracks and to add body to guitars without colouring the original tone. Chorus can also be used with discretion to thicken a vocal track.
User Manual 10.3.1: MISC FX PARAMETERS LEXICON FX > DELAYS > DELAY PARAMETERS Speed Sets the speed at which the modulated effect cycles. Depth - LFO Depth Scales the intensity of the effect. This control affects the output of the LFO only. It has no effect on the outputs of the individual waveforms. Voices - Number Of Voices Controls the number of additional Chorus voices. Higher amounts add more richness to the Chorus effect.
User Manual 10.3.1: MISC FX PARAMETERS LEXICON FX > DELAYS > DELAY PARAMETERS Waveform Selects the wave pattern used by the modulated effect. Select from sine wave, triangle wave, Stepped Triangle, and random. Phase Controls whether amplitude or depth change occurs in both left and right outputs simultaneously or alternates between left and right outputs. This control affects the output of the LFO only. It has no effect on the outputs of the individual waveforms.
User Manual 10.3.1: MISC FX PARAMETERS LEXICON FX > DELAYS > DELAY PARAMETERS Rot Max Sets the maximum speed at which the LF Speaker will rotate. Rotary effect only: The speed limits are used when the speed parameter is changed from Slow to Fast. Horn Min Rotary effect only: Minimum speed of the HF rotary horn. The speed limits are used when the speed parameter is changed from Slow to Fast. Horn Max Rotary effect only: Maximum speed of the HF rotary horn.
User Manual 10.3.1: MISC FX PARAMETERS LEXICON FX > DELAYS > DELAY PARAMETERS Fdbk 'n' - Feedback Adjusts how much of the shifted signal is sent back through the delay line in Pitch Shift and Detune. For creating cascading arpeggio-type effects. Pan 'n' Sets the pan position in the stereo field for each tap in the 2-Tap Delay or each channel of the pitch shift/detune effects.

User Manual APPENDIX 01: NO SOUND? NO SOUND? A Troubleshooting Guide. One of the most common problems experienced with mixing consoles is finding that an input isn’t appearing at an output. There are many possible reasons for this, but the best way to troubleshoot it is to first make sure the Control Channel is set up correctly and to go through the signal path and workout where the ‘break’ is... You can check the exact audio path of any signal by referring to the signal path diagrams in Chapter 6.
User Manual APPENDIX 01: NO SOUND? NO SOUND? Is the Gate shut? It is possible for an incorrectly set Gate process to stop all signal. This happens most often when the threshold is set too high and the signal never gets loud enough to 'open' the Gate. You can easily check this by turn the Gate process off with the GATE button in the GATE section of the ACS (7.2.2).
User Manual APPENDIX 01: NO SOUND? NO SOUND? Is the Signal Routed to a valid output bus or channel? Routing can cover LR and Mono routing, as well as Mix bus routing. This will depend on the particular instance. If the issue is no output at the main LR or mono outputs for example, then check than the signal is routed using the LR and/or MONO buttons in the ACS OUT section (7.2.5).
