Focusrite ISA ADN8 Dante A/D Ca
With the introduction of the ISA ADN8, the classic ISA mic pre can be implemented directly on a Dante network, providing console-grade preamps to the most advanced of audio networks. ISA ADN8 is an optional eight-channel A-D card that provides high-quality, precision analogue-to-digital conversion for the Focusrite ISA 428 MK2 and ISA 828 MK2 microphone preamps. Featuring Dante, AES3 and ADAT connectivity, the card operates at sample rates up to 24-bit/192kHz.
The card offers a familiar set of standard professional connectors with primary and secondary RJ45 Dante output ports, an AES59 DB25 connector for AES3 output, and a pair of TOSLINK connectors for ADAT output. Word Clock I/O on BNC connectors allows synchronisation with many external devices.
Key Features
• Eight-channels of high-quality, precision analogue to digital converter for ISA 428 MK2 and ISA 828 MK2
• Up to 24-bit/192kHz sample rate
• Dante connectivity via Primary and Secondary Ethernet ports for redundancy and auto switchover in case of failure
• Industry standard eight-channel AES59 DB25 output connection for AES3
• Two TOSLINK connectors for ADAT (8 channels at up to 96kHz; 4 channels at 192kHz)
• Word Clock I/O on BNC connectors allows synchronisation with many external devices
• RedNet Control and Dante Controller software allow Dante routing and control from a computer; no hardware patching required
