Focusrite ISA 2-Channel Stereo A/D 192kHz ADC Microphone Preamp Card

Focusrite's ISA 2-Channel Stereo A/D 192kHz ADC Microphone Preamp Card embodies cutting-edge conversion technology, encompassed within pristine Focusrite circuitry. This analog to digital converter card is designed for use with Focusrite's ISA One or ISA 430 MKII microphone preamps. The ISA stereo ADC provides two channels of the highest quality 24-bit conversion at all sample rates up to 192 kHz. Digital output formats include two-channel single/dual wire AES/EBU or two-channel S/PDIF, all via a 9 pin D-type connector, as well as optical S/PDIF and ADAT. The ADAT (TO Slink) port is stereo and operates at 24-bit, up to 96 kHz. 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.
