A&E Specifications
The mixer shall be a compact digital mixer built around a 96kHz XCVI FPGA core with 48 input channels mixing to LR and 12 stereo mix outputs.
The surface shall include 33 moving faders with 6 layers, each layer having dedicated keys, giving easy access to input channels, mixes, FX sends, FX returns, DCA masters and MIDI control.
Each fader strip shall have dedicated PAFL, Select, and Mute buttons with indicators, a variable LED meter, a peak indicator LED and variable colour backlit LCD display.
There shall be dedicated physical controls which allow for adjustment of key processing parameters, and which follow the select button for the input and output channels.
The fader and rotary controls shall be of a high contrast colour to the mixer surface for excellent visibility during operation in low light conditions. The rotary controls shall also be illuminated to indicate function and availability for use.
Send levels to mixes shall be displayed and adjusted using the faders.
Surface illumination shall be integrated into the bodywork of the mixer.
Local analogue inputs shall use balanced XLR sockets and connect to fully recallable digitally controlled preamplifiers. These shall be able to provide up to +60dB of gain, industry standard 48V phantom power, and include a switchable -20dB Pad to allow a maximum input level of +30dBu.
Local analogue outputs shall be provided on 16 XLR sockets and 2 balanced TRS ¼ inch Jack sockets.
These will have a nominal line output of +4dBu and a maximum output of +22dBu.
There shall be a local “SLink” Ethernet audio expansion port with locking EtherCON connector, supporting multiple AoIP protocols and providing access to a maximum 128x128 digital channels, connected over a single cable ‘digital snake’ and allowing remote preamp control of Allen & Heath Remote Audio Units, as well as connection to Allen & Heath ME Personal Mixing Systems.
A digital I/O Port shall be provided to accept optional cards, supporting a maximum 128x128 channels and the ability to interface with 3rd party AoIP protocols such as Dante and Waves.
All input and output processing, routing options and system configuration shall be accessed and adjusted via a 7-inch colour touchscreen and associated dedicated rotary control.
16 user-assignable SoftKeys with variable colour LED illumination shall be provided for quick access to Input/Mix/DCA/Group Mutes, Tap Tempo, Scene Controls, MMC and SQ-Drive Controls, as well as 8 assignable rotary encoders with LCD display showing their current function.
A footswitch connection shall be provided to allow assignable control from an optional single or dual footswitch.
There shall be dedicated keys for quick Copy/Paste/Reset of processing parameters and mixes.

The ability to assign channel on/off status and to switch between Pre/Post fade to the currently selected mix shall also be provided with dedicated keys.
All input channels shall contain the following processing: Polarity, Trim, Insert, Gate, High Pass Filter, Parametric EQ, Compressor, Delay, Pan. All FX Return channels shall contain the following: Parametric EQ, Pan.
All output mix channels shall contain the following processing: External input, Polarity, Trim, Insert, Parametric EQ, and Graphic EQ with RTA and faderflip mode, Compressor, Delay, Balance.
All signal delays in the system shall be adjustable in Milliseconds.
The mixer will allow the insertion of Allen & Heath DEEP processing models to channels, without affecting latency or processing abilities.
8 user-assignable effect racks shall be provided with a library of factory preset FX emulations. The FX racks shall be individually configurable as send/return from a channel or FX/Mix, or inserted into input or output channels.
There shall be 8 DCA groups and 8 Mute groups.
An Automatic Mic Mixer shall be provided for automatic and dynamic adjustment of gain in spoken word applications.
A global source option for the direct out of each input channel shall be provided in the routing screen. The tap-off point shall be adjusted to the following positions in the processing path: post Preamp, post HPF, post Gate, post Insert return, post PEQ, post Compressor, and post Delay. There shall be further global options to follow Fader, DCA and Mute. Direct outputs shall be assignable via the mixer soft patch bay.
A Talkback facility shall be provided with the ability to send to any output mix with on screen status indication. An option to enable talkback latching and HPF shall be provided.
A signal generator shall be provided with the ability to send a variable level signal to any output mix with visual assignment status on-screen. The following types of signals shall be available: Sine, White Noise, Pink Noise, and Band-Pass.
Comprehensive input, output, and FX channel and RTA metering shall be provided on-screen. 12-LED bar meters on the surface shall indicate the
Main mix bus level and the PAFL signal shall override the LR meters accompanied by a PAFL-active indicator.
A default Mains to PAFL sub-mix shall be provided.
There shall be a USB Type-A connector on the surface for stereo/multitrack recording/playback, data-transfer, archiving, and firmware updates direct to USB drives. On the rear panel there shall be a USB-B connection following the USB 2.0 standard for multi-channel, bidirectional audio streaming and MIDI DAW control between the mixer and a computer.
A DAW transport control using popular DAW control protocols for computer shall be available via the touch-screen.
Stereo digital output shall be provided on XLR following the AES/EBU standard and with switchable sample rates.
The mixer shall provide a Fast Ethernet (100 Mbit/s) port for Cat5 cable connection to a computer for MIDI over TCP/IP control of mixer parameters via a wireless router (access point) for live mixing control, and the mixing system shall include application software for tablet and phone devices connected via a wireless network router to the LAN port.
Input and output channel processing and parameters in the mixer shall be saved on demand as a user library item for recall in other channels. All library items shall be archived with the show-file. Library items shall be transferrable to USB drive as portable data to be used in other systems.
The mixer shall provide the facility to save 300 scenes of the settings of the mixing system and these scenes shall be nameable.
A comprehensive table of ‘Scene Safes’ shall be provided to prevent selected items from being changed from their state when the safe was enabled. A comprehensive scene filter shall be provided per scene to Allow / Block each parameter saved in a scene from being changed as that scene is recalled.
An option shall be provided for password protection for log-in of several users with different levels of system access and permissions. A particular scene may be chosen to be recalled per change of userlogin if desired.
The mixing system shall periodically record all current settings and return the mixer to that state after reboot following a power-cycle.
The mixing control surface shall have a built in power supply accepting AC mains voltages of 100~240V, 50/60 Hz, 110W max via an earthed 3-pin IEC male connector mounted on the rear chassis. A Two Pole Push-Button switch shall be provided near the mains input.
Recommended operating temperature for the mixer shall be 5 to 35 degrees Celsius.
The mixer shall be the Allen & Heath SQ-7.
