Product Description for the Focusrite OctoPre MKII Preamp

With eight channels of Focusrite preamplification and a built-in 24-bit / 96 kHz ADAT output, OctoPre MkII is Focusrite’s powerful input upgrade for your Pro Tools system, or any digital audio workstation. It’s also a great expansion for any analogue or digital console, or hard disk recorder.

The digital output allows you to make the most of often-neglected ADAT inputs; ideal for expanding the number of mic pre inputs on your interface. Connect OctoPre MkII to your audio interface’s ADAT input to create a high quality, multi-channel recording solution, ideal for tracking drums, as well guitars, keyboards, vocals and more.
