The MARC 2 PRO has 2 channels of 24-bit/96kHz balanced Analogue I/O on XLR's, and 2 channels of 24-bit/96kHz Digital S/PDIF I/O (on RCA or optical connectors) or AES/EBU (XLR's) plus a Wordclock input providing connectivity to a whole world of digital and analogue devices.

All the MARC cards have multi-client drivers with extremely low latencies (down to 2 ms at 96kHz) with ASIO, GSIF and DirectSound, making them especially suitable for time critical applications, such as Soft synth and Samplers like GigaStudio, Reason, Halion etc.

MARC 2 PRO hardware is ready for the next generation ASIO-IN-HARDWARE feature. This will enable direct access to the cards memory giving even better performance using any ASIO recording software including Cubase, Cubase SX, Wavelab 4, Nuendo, Ableton Live etc. This feature will be available fully functional with future driver updates.
