Focusrite ISA ADN2 Two-Channel A-D Card with Dante for ISA One

ISA ADN2 is the retrofit A-D card for the ISA One. It fits the host unit's option slot and converts both of its channels, the microphone path and the DI, at up to 24-bit / 192 kHz with 121 dB of A-weighted dynamic range, so the preamp keeps its analogue character and gains a digital output without an outboard converter in between.

Once fitted, the ISA One appears on a Dante network through dual RJ45 ports, and the same card also carries AES3 on XLR, ADAT on TOSLINK, S/PDIF on RCA and word clock in and out on BNC. That covers both jobs the card gets bought for: putting a favourite preamp onto an audio-over-IP network, and feeding a legacy digital console directly.
