DESCRIPTION
The AR84 is an expander audio interface rack for the Allen & Heath GLD and Qu digital mixing
systems. It provides 8 remote controlled mic/line preamps and 4 XLR line outputs. Up to two AR84
AudioRacks can be added to a GLD system. The AR84 can connect directly to the mixer or to the
AR2412 AudioRack to expand the number of system inputs and outputs.
The AR84 is simply an audio interface. It cannot be used by itself. It must connect to the GLD or Qu
mixer which is where the audio is processed.
The AR84 is not compatible with Allen & Heath iLive Series components or ACE connection.
Refer to the GLD User Guide AP8561 and Qu User Guide AP9372 for instructions on connecting
and using the AR84 with your system. Refer to the Allen & Heath web site for more information and
suitable Cat5 cables.
FEATURES
• 1• Input sockets 8 balanced XLR inputs for microphone and line level sources. The preamps are built into the AR84 rack and their Gain, Pad and 48V phantom power is remote controlled from the mixer via the digital link. The output of the analogue preamps are converted to digital format and transported via a Cat5 cable to be processed and mixed at the GLD or Qu mixer.
•
