Description
64-in / 64-out audio interface with eight digitally-controlled, ‘Air’ enabled, Red Evolution mic preamps and dual Thunderbolt™2, Pro Tools|HD and Dante™network audio connectivity.
Red 8Pre – The newest spin on Focusrite’s best interface yet. There’s never been a better Focusrite audio interface range than the Red Range. The second member of this acclaimed new series, the Red 8Pre features eight new, specially-developed ‘Red Evolution’ mic preamps with ‘Air’ transformer emulation, high-headroom instrument inputs, a new low-noise conversion design plus a grand total of 64 inputs and 64 outputs (including 16 analogue inputs and 18 analogue outputs), Red 8Pre incorporates dual Thunderbolt™2 ports for round-trip latency as low as 1.67ms, and direct connection to Pro Tools | HD systems. Add to that the ability to connect up to 32 additional inputs and outputs via Dante™Ethernet-based audio networking and you have one of the most advanced, best-sounding, and most versatile interfaces
