Description
8-Channel a/D Card for Focusrite ISA 428 MkII and ISA 828 MkII with AES3, ADAT, and Redundant Dante Connectivity
The ISA eight channel 192kHz A-D converter outperforms every other converter yet devised, and is the first audio A-D converter to utilise Burr-Brown Pro Audio Amplifiers and flagship PCM4220 A-D converter chips. With cutting-edge conversion technology seated within Focusrite custom analogue circuitry, the card delivers unparalleled performance; specifications include a dynamic range of 122dB and jitter less than 250 picoseconds.
The card can be retrofitted to an ISA 428 or ISA 828 at any time and, thanks to its convenient 25-pin D-Type connector, integrates seamlessly with ProTools HD as well as other popular hard disk recorders and mixing desks.
Digital formats include an eight-channel single/dual wire AES/EBU and S/PDIF output, as well as an eight-channel ADAT lightpipe (SMUX/SMUX2) output. Word clock i/o is provided via dedicated BNC connectors.
