The ISA stereo ADC embodies cutting-edge conversion technology, encompassed within pristine Focusrite circuitry, providing 2 channels of the highest quality 24-bit conversion at all sample rates up to 192kHz. Digital output formats include 2 channel single/dual wire AES/EBU or 2 channel S/PDIF, all via a 9 pin D-type connector, as well as optical S/PDIF and ADAT. The ADAT (TOSlink) port is stereo and operates at 24-bit, up to 96kHz.
The card comes as standard with the ISA One Digital and can be retrofitted to an ISA 430 MKII or an ISA One at any time.
