The 828mkII contains everything you need to turn your Mac or PC computer into a powerful 24-bit, 96kHz digital audio workstation. With simple plug-and-play operation via FireWire or "high-speed" USB 2.0, the 828mkII provides 20 inputs and 22 outputs, including 10 channels of pristine 96kHz analog recording and playback, combined with 8 channels of ADAT digital I/O and stereo S/PDIF. Expand your system by connecting additional interfaces. The 828mkII is equally well-suited for studio and stage, with or without a computer. As a computer interface, the 828mkII provides 20 separate inputs and 22 outputs, including separate main outs and headphone out. The two mic/guitar/instrument inputs feature analog, pre-amplified sends which allow you to insert your favorite outboard EQ, compressor, guitar amp, reverb or other effects processor before the signal goes digital. Use any input as a return.
