Focusrite RedNet A16R Dante Audio Network Interface

The Focusrite AMS-RedNet A16R is a 1U, 16×16 analogue line-level I/O interface for any Dante™ audio-over-IP network. Featuring network and power supply redundancy, RedNet A16R 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 four 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 A16R, or alternatively allows A16R 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.

Features:

• 16 channels of high-quality line-level analogue I/O for Dante audio-over-IP networks
• 24-bit precision conversion up to 192kHz
• 119dB dynamic range, flat from 20Hz – 20kHz, +/-0.15dB
• Software-selectable +24dBu or +18dBu level alignment
• AES67 compliant
• Dual power supplies and network connections with full power and network redundancy including locking connectors for maximum reliability
• Comprehensive front-panel metering and indicators
• Remote monitoring software with powerful graphic user interface
• Analogue I/O to AES59 standard on DB25 connectors
