Focusrite RedNet A16R MKII – 16×16 Analogue Dante AD/DA Converter with Independent Level Control & Dual PSUs

OVERVIEW

The RedNet A16R MKII is a 16-channel analogue Interface for Dante networks, with two channels of AES3 I/O.

Individual input and output channel level controls allow for precise adjustment of all I/O levels using RedNet Control. With two power supplies and primary and secondary etherCON network connectors, RedNet A16R MKII is perfect for critical-path applications in recording, post-production, live sound and broadcast. Built-in redundancy features allow for silent failover in the event of a power or network outage, providing reassurance for system technicians.

Analogue inputs and outputs are connected through four rear-panel AES59-configured DB25 connectors, while an additional pair of AES3 I/O is provided through male and female XLRs for added flexibility. The XLR input can accept DARS signals in addition to AES3. Word Clock I/O on BNC connectors allows external devices to clock to RedNet A16R MKII, or alternatively allows RedNet A16R MKII to act as a network clock grand master, synchronised to external input.

RedNet A16R MKII is well suited to permanent installation and repeated strike and setup: all connectors lock and remain terminated even under stress, providing worry-free installation and peace of mind once situated in a rack. In addition, all Focusrite products come with a three-year warranty and award-winning customer support.

KEY HIGHLIGHTS

16×16 AES3 I/O with Independent Level Control

The RedNet A16R MkII is a 16-channel bi-directional AES3 interface for Dante® networks. The 1U rackmount device features individual input and output channel level controls, allowing for precise calibration and control of all input and output levels using RedNet Control. RedNet A16R MkII features power supply and Ethernet redundancy with auto switchover in case of failure.

Various connection options make RedNet A16R MkII a flexible addition to any Audio-over-IP system. A pair of DB25 multipin connectors each connect eight channels of AES3 I/O into and out of the interface, while XLR and RCA ports enable two-channel AES3 and S/PDIF connections, respectively, to be made.

Sample rate conversion on every input enables external equipment to operate at different sample rates, and DARS signals are accepted on the XLR connector. Word Clock I/O on BNC connectors allows synchronisation to house clock, or syncing external equipment to the Dante network.
