ISA ADN2

Description

With the introduction of the ISA ADN2, the classic ISA mic preamp can now be integrated directly into a Dante network, bringing console-quality preamps to the most advanced audio networks. The ISA ADN2 is an optional two-channel A-D card that provides high-quality analog-to-digital conversion for the ISA One mic preamp and DI. With Dante, AES3, ADAT, and S/PDIF connectivity, the card supports sample rates of up to 24-bit/192 kHz.

The card features a familiar set of professional-standard connectors, including primary and secondary Dante RJ45 output ports, an XLR connector for AES3 output, a TOSLINK connector for ADAT output, and an RCA connector for S/PDIF output. Word Clock I/O on BNC connectors allows synchronization with a wide range of external devices.

The card’s Dante outputs provide ISA One with network connectivity to all Focusrite RedNet and Red interfaces, as well as any other Dante-enabled devices from hundreds of manufacturers. Metering and settings are accessible via RedNet Control, and routing is managed through Dante Controller. RedNet Control software is included.
