12. Appendix A – Rack FX The Rack FX selection combines the pristine quality and wide choice offered by boutique plug-ins with the convenience and low latency of onboard processing. 12.1 Rack FX models SMR Reverb - SMR Live is a Spatial Modelling Reverberator featuring 4 fully configurable complex spatial models Classic, Hall, Room and EMT. Each of these models use different reflection and decay algorithms to provide natural sound spaces ideal for Live sound. Classic Emulates high quality plates.
Stereo Tap Delay - Provides a clean digital delay with a maximum delay time of 2.7 seconds. One of the key features of the stereo tap delay is the ability to synchronise the delay times to note intervals based on the effects beats per minute value. The delay has two modes of operation: BPM mode -Delay time is determined by the selected beats per minute and corresponding note value. Standard, dotted and triplet intervals are selectable via the interval selection wheel from whole to 16th intervals.
Chorus - Chorus derives from the late 80’s where different stereo field creation techniques influenced the sound of each chorusing unit. Chorus recreates the classics using 3 stereo-field emulations. These emulations can be switched in any combination creating many different stereo fields. All switches up gives no stereo enhancement. The traditional Rate and Depth controls cover the centre panel. The LFO driving the modulator can be switched to sine or rectified shape.
Attack - Time period for gate to open. Hold - Time period that the gate remains fully open. Release - Time period for gate closing. Maximum gate open time (attack + hold + release) = 500ms. Models: Classic nonlinear - Emulates the faithful 80’s classic gated reverb. Panner - Rapid panning between L and R in the reverb. Short time movement FX. Powerbox - Max power in gated energy. Not as de-correlated as classic non-linear.
VS1 Vocal Shift - VocalShift VS1 is a stereo vocal pitch shifter squeezing two channels of high quality pitch shifting into a single effect. It has a very low latency (<6ms), covers the whole vocal frequency range, and minimises the phasing and flutter artefacts common with many pitch shifters. VocalShift allows large shifts of up to +/- 1 octave, with a further switchable octave downshift. The wide range makes it ideal for theatrical or more extreme musical effects.
Frequency - Adjusts the lower boundary of the region thought to contain sibilance. This will typically be around the 6kHz range. Adjust the value to capture the “ess” heard on the channel. The frequency is adjustable from 3kHz to 8kHz. Like many advanced De-Essers this is not a simple notch filter. Typically you need to set the frequency slightly lower than the centre frequency of the ‘ess’. Reduction - Provides control over the amount of gain reduction applied to the selected frequency band.
• Peak Manual • RMS Manual • Auto Punch • Auto Opto • Slow AutoF • Fast AutoF Knee - Hard or Soft (easy knee model). Link and Relative modes: There are three operating modes with two buttons at the top right of the screen: • • • Normal - Link and Rel buttons turned off. Independent control of each band. Link - All band parameters linked for quick setup. Relative - All band parameters linked for changes relative to settings made before the Rel button was turned on.

14. Appendix C – Template Sessions Template Sessions provide a quick starting point by giving you a simple and familiar layout. They may contain default Snapshots to reset some of the 4REA4 settings such as strip assign layout to a known starting point. They also have default Snapshot Global and Area Safe settings that will serve as a logical starting point for configurations – these settings can be changed and the sessions resaved as User sessions.
15. Appendix D – I/O Module Options Note that DMI Cards and SD Rack (Local) cards must not be “hot swapped” – to insert or remove cards, please power down the 4REA4 Unit first. 15.1 4REA4 I/O Control Via DiGiCo SD Console A DiGiCo SD console can control the I/O connected to a 4REA4 via either a DMI-MADI (B or C) or a DMIOpto. Sockets of I/O either on or connected to the 4REA4 can be tie lined to the connection to the SD console on a per socket basis.
15.2 A164 Wall LCD 1 2 1 Redundancy - A3232 devices can be run in redundant mode 2 Display Settings – The Brightness and Contrast of the displays of each A164 Wall LCD can be controlled by adjusting the controls relative to the correct Port and Device. Note that this menu can also be found under the AStar tab for devices connected via an AStar. 15.
15.4 DMI MADI (B or C) 1 2 3 1 MADI Sample Rate Display – Shows the sample rate of the MADI card 2 96kHz Mode – There are 2 MADI standards when running at 96 kHz, SMUX (48k frame) and High Speed (true or 96k frame). 96Khz SMUX MADI uses a native 48 kHz clock which the DMI can detects and report. This 48kHz SMUX clock cannot be differentiated from a standard 48 kHz without intervention. If SMUX Mode is required, the SMUX mode needs to be manually set.
3 Channel Count – when connecting to an SD console, channels must be ‘reserved’ on the Optocore loop. Choose the number of channels needed from the drop down menus. NOTE: Input Channel Count refers to the inputs from the 4REA4 to the Optocore loop (outputs from the 4REA4) and vice versa for the Output Channel Count 15.6 DMI Dante DMI Dante card will need Dante Network configuration in addition to its Sync Source settings.
15.8 DMI Waves DMI Waves Card will need Soundgrid Network configuration in addition to its Sync Source settings. This is done using either Waves MultiRack or SoundGrid Studio, both of which are available from: http://www.waves.com/downloads 15.9 DMI Mic 8 analogue Mic Pre-Amps with gain and +48V control 15.10 DMI ADC 16 Line level only analogue inputs on 2 x 25 way D-Sub connectors – there is no gain or +48V control on these cards. 4REA4 Controller Software User Guide 86 V1.
15.11 DMI DAC 16 Line level only analogue outputs on 2 x 25 way D-Sub connectors 15.12 DMI Aviom 16 Output channels at 48KHz (with SRC) supporting the Aviom A-Net Pro16 protocol 15.13 DMI Cards - Updating Firmware and FPGA Codes (V1.20+) DMI Cards require both Firmware and FPGA Code. Connect Controller to a 4REA4 containing one or more DMI cards.
If a DMI Card is fitted in a slot then it will show the Current versions of Firmware and FPGA Code running on the card and any Available versions. Firmware Version 0 indicates no valid firmware for that DMI Card type. FPGA Code versions are denoted by dates and a blank entry denotes no valid FPGA code for that DMI Card type. An Available version will be shown if a file suitable for the DMI Card type is found in the following location on the machine running Controller: Windows: C:\Program Files (x86)\DiGiCo\
16. Appendix E – Multiple Software Controllers 16.1 Sessions In a typical Multi-Controller system, each Controller computer would store and recall its own Session independently of other Computers running Controller software. Although the 4REA4 Engine data would be the same in each Controller’s Session file, the Controller data would be unique to the Controller that stored the Session. When loading Multi-Software Controller sessions, the last user to store the Session would recall the Session as normal.
