Focusrite RedNet A8R
RedNet A8R expands Focusrite’s growing range of 1U Dante interfaces with network and power supply redundancy, providing eight channels of analogue input and output. RedNet A8R offers high quality 192kHz/24-bit A-D and D-A digital conversion with up to 119dB dynamic range, plus two channels of AES/EBU digital I/O, to and from the Dante network.
RedNet A8R provides 24-bit conversion at 44.1, 48, 88.2, 96, 176.4 and 192kHz sample rates (remotely-selectable) and includes pull-up/down capability. Electronically-balanced analogue audio I/O is provided on DB25 connectors wired to AES59 specifications. Internal signals are balanced throughout. Inputs and outputs are remotely configurable for 0dBFS= +18dBu or +24dBu signal levels. In addition, two channels of AES/EBU I/O are provided on XLR connectors, with sample rate conversion on the input. The clock source for the unit may be internal, or external via Word Clock or DARS (via the XLR input). RedNet A8R also outputs Word Clock.
RedNet A8R features power and network redundancy, with two separate universal (100–240V) PSUs, which include IEC connectors with retaining clips, plus dual network interfaces on locking etherCON connectors. These ports can be configured remotely to Redundant or Switched (daisy-chain) mode.
