FX/Mix, or inserted into input or output channels.
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 for Follow Fader, and
Follow Mute.
Direct outputs shall be assignable via the mixer soft patch
bay to any physical output socket interface channel or ME
channel.
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.
Real Time Analysis metering shall include a spectrogram to
allow for accurate monitoring of audio energy across the
frequency spectrum over time for the purpose of feedback
detection and correction of room acoustics.

control of mixer parameters via a wireless router (access
point) for live mixing control.
The mixing system shall include application software for
Apple iOS touchscreen devices connected via a wireless
network router to the LAN port and allow control of functions
including the preamp gain, pad, and phantom power.
The application shall have a graphical representation of
physical controls and indicators present on the surface
including signal processing parameters and shall provide
control of output channel processing including Parametric
EQ, Graphic Eq, Compressor and Delay. Routing
assignments and level adjustments of input signals to all
mixes and bus shall be provided. The application software
shall provide signal metering and processing threshold
indication when online including the Real Time Analyser.
There shall be a local “dSNAKE” Ethernet audio expansion
port with locking Ethercon connector, providing up to 38 input
signals and 20 output signals, plus 40 personal mixing sends
to be connected over a single cable ‘digital snake’ and
allowing Remote Preamp control to an Allen & Heath
AudioRack, or Allen & Heath ME Personal Mixing Systems.
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. Individual processing sections shall
be save-able on demand as user library items for that type.
All library items shall be stored on board and 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 100 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 user-login if desired.
The mixing system shall periodically record all current
settings and return the mixer to that state after reboot
following a power-cycle.
