With eight channels of Focusrite microphone preamplification, eight VCA-based Red 3-derived compressors and built-in 24-bit / 96kHz digital inputs and outputs, OctoPre MkII Dynamic is Focusrite's feature-rich expansion upgrade for any digital audio workstation. It's equally an ideal expansion for any analogue or digital console, or hard disk recorder.

Digital inputs and outputs let you make the most of often-neglected ADAT I/O; ideal for expanding the number of mic pre inputs on your interface or for providing analogue monitoring from any digital ADAT feed.

With this entire package fitting into a single 1U chassis complementing Focusrite's Saffire PRO range, and all controls adjustable from the front fascia, OctoPre MkII Dynamic sets the standard for modern, compact, multi-channel recording expansions.
