The Ethernet protocol shall provide control to the remote preamp, and all mic preamps are scene recallable by the digital mixing system. Phantom power LED indicators shall be provided per input socket on the remote audio rack. Unit firmware shall automatically be updated when connected to the digital mixing system. The local Ethernet port shall be an RJ45 socket with EtherCon locking ring.
It shall also be possible to connected the remote audio rack to a main AudioRack unit to add a further 16 XLR inputs and 8 XLR outputs from that location. This connection shall be via an `Expander’ connection and shall also be an RJ45 socket with EtherCon locking ring.
The remote audio rack shall provide an `Expander’ port to allow the connection of an additional remote audio rack from that location. This connection shall also be a `dSNAKE’ RJ45 socket with EtherCon locking ring. This port shall also provide 40 channels to Allen&Heath ME personal monitoring solution hardware and the remote audio rack shall be compatible with Allen&Heath digital mixers.
The remote audio rack 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. The remote audio rack shall also be mounted in a 19″ equipment rack or case using an optional remote audio rack kit.
The remote audio rack shall have a built in power supply accepting AC mains voltages of 100~240V, 50/60 Hz, 45W max via an earthed 3-pin IEC male connector mounted on the rear chassis.
Recommended operating temperature for the remote audio rack shall be 5 to 35 degrees Celsius. The unit shall be the Allen&Heath AB168 Portable AudioRack.
