Description
The Focusrite RedNet A8R is a 1U, 8×8 analogue line-level I/O interface for any Dante audio-over-IP network. Featuring network and power supply redundancy, RedNet A8R is the ideal choice for providing analogue I/O in many critical-path applications, whether in Post Production, Broadcast, Live Sound or the Recording Studio.
High-quality conversion with up to 119dB of dynamic range is provided through two rear-panel DB25 connectors while an additional pair of AES3 I/O is provided through male and female XLR for added flexibility. Word Clock I/O on BNC connectors allows external devices to clock to RedNet A8R, or alternatively allows RedNet A8R to act as a network clock grand master slaved to external input. Power is supplied through a pair of locking IEC power inlets, and network connections are provided with a pair of locking Neutrik etherCON connectors; providing redundant operation or daisy-chained operation.
