Focusrite says:

The Scarlett OctoPre is the ideal 8-channel expansion for any Scarlett — or other digital interface with ADAT inputs. ADAT is a simple and easy way of increasing the number of simultaneous recording channels available in your studio. With eight channels of Focusrite's 2nd generation Scarlett preamps and precision A-D conversion at sample rates up to 192 kHz, Scarlett OctoPre is the ideal way of increasing the number of inputs in your studio. It also offers eight balanced line outputs, sourced directly from their respective mic preamps for use on stage in a live environment.

Eight natural-sounding 2nd generation Scarlett mic/line inputs deliver high headroom, plenty of clean gain, low noise and minimal distortion — ideal for tracking drums as well guitars, keyboards, vocals and more. The front panel features two newly-designed instrument inputs with extended headroom. ADAT outputs let you connect to any interface or digital system with ADAT optical inputs, and analogue line outputs let you feed an analogue console at the same time as recording with the digital outputs.
