Two-channel A-D card for ISA One, including Dante connectivity

ISA ADN2 is an optional two-channel A-D card that provides high-quality analogue-to-digital conversion for the ISA One mic preamp and DI. Featuring Dante, AES3, ADAT andS/PDIF connectivity, the card operates at sample rates up to 24-bit/192kHz.

The card offers primary and secondary RJ45 Dante output ports, an XLR connector for AES3 output, a TOSLINK connector for ADAT output and RCA connector for S/PDIFoutput. Word Clock I/O on BNC connectors allows synchronisation to multiple digital sources. This also includes syncing the Dante network to house clock,or for syncing external equipment to the Dante network.

Dante outputs on the card provide ISA One with network connectivity to all Focusrite RedNet devices and Red interfaces, as well as any other Dante-enabled device from hundreds of manufacturers. Metering and settings are accessed through RedNet Control, routing is configured using Dante Controller.

And as with all Focusrite Pro products, wherever you happen to be in the world, you can rely on a three-year warranty if any Focusrite Pro hardware needs repairing or replacing due to a manufacturing fault.
