A&E Specifications
The unit shall be a portable remote audio device for Dante
enabled Allen & Heath mixing systems. The remote audio
unit shall provide 16 XLR inputs with individually configured
Phantom Power and 8 XLR outputs. Phantom power LED
indicators shall be provided per input socket on the remote
audio rack. The unit shall be able to provide 48kHz or 96kHz
sample rate on a Dante network.
Two Ethercon connectors shall be provided for transport of
the digital audio and control signals over Dante. The unit
shall be able to operate in ‘redundant’ or ‘switched’ mode by
means of software. In ‘redundant’ mode the unit shall
provide full redundant connection to any Dante enabled
device. In ‘switch’ mode the unit shall allow daisy chained
connection of multiple units. The unit shall have a hardware
“Network reset” switch.
The Ethernet protocol shall provide control to the remote
preamp, and all mic preamps shall be recallable by the
mixing system.
The remote audio unit shall have a robust steel chassis and
shall be designed to be portable and to be placed
horizontally or vertically on the stage or performance
environment.
A carrying handle shall be provided to facilitate lifting and
holding the device when moving and an optional padded
dust cover shall be available.
An optional 19” rack mounting kit shall be available.
The remote audio unit shall have a built-in power supply
accepting AC mains voltages of 100~240V, 50/60 Hz, 40W
max via an earthed 3-pin IEC male connector mounted on
the rear chassis.
Recommended operating temperature for the remote audio
unit shall be 0 to 40 degrees Celsius.
The unit shall be the Allen & Heath DT168.
