4.2 Local Output Connections
Group, Mix, Matrix outputs
– Balanced XLR line
level outputs for the mono and stereo mixes, for example to
feed monitor amplifiers, external processing devices, delay
fill speaker systems and recording devices. These use low
impedance, high quality differential driver circuits for
connection to +4 or 0dBu equipment. Maximum output is
+22dBu.
Professional equipment provides ‘balanced’ connections for
maximum interference rejection over long cable runs. If you
are connecting to ‘unbalanced’ equipment then make sure
the XLR pin 3 (signal cold) is linked to pin 1 (signal ground).
Main LR output
– Balanced XLR line level outputs for
the main Left and Right stereo mix. These typically plug into
the FOH speaker processor, amplifier or powered speakers.
AES out
– 2-channel digital output using a single XLR
connection and standard mic (2-core screened) audio cable.
It follows the AES (Audio Engineering Society) digital audio
standard and can connect to any equipment fitted with an
AES input socket. The source to this output is patched using
the
Setup / Output Patch / Surface screen. Applications
include the feed to a PA speaker processor, amplifier, stereo
broadcast or recording device equipped with AES input.
Alt out
– Stereo ‘alternative’ output on balanced TRS
jacks for connection to +4 or 0dBu equipment such as zone
feeds, fill speakers, broadcast or local monitor. The source
to this output is patched using the
Setup / Output Patch /
Surface screen.
2TRK out
– Stereo output on balanced TRS jacks for
connection to +4 or 0dBu equipment such as stereo
recorders. It follows the post master fader main LR mix.
4.3 Other Connections
Lamp
– Plug in a 4-pin gooseneck lamp to illuminate the
mixer surface. You can use any industry standard 12V, 5W
or lower power lamp. We recommend the Allen & Heath
LEDLamp with built-in thumbwheel dimmer.
USB B
– Type B USB connection for multi-channel
bi-directional audio streaming between the mixer and a
computer. Follows the high speed USB 2.0 standard.
Refer to the Allen & Heath web site for information on
Windows
® and Apple ® Mac drivers available for Qu.
Network
– Fast Ethernet (100 Mbit/s) port for Cat5 cable
connection to a computer for MIDI over TCP/IP control of
mixer parameters, or to a wireless router (access point) for
live mixing control using the Allen & Heath Qu-Pad app
running on an iPad. The Lnk indicator flashes to indicate
network activity.
dSNAKE
– The proprietary Allen & Heath ‘digital snake’
connection for remote audio using an AR2412, AR84 or
AB168 AudioRacks, and for personal monitoring using the
ME Personal Mixing System.
