All of Focusrite's FireWire interfaces are fully compatible with Thunderbolt using a simple FireWire to Thunderbolt adapter. Focusrite fully supports the use of Thunderbolt with our FireWire interfaces. More information.
We always quote 'real world' performance figures (measured to the AES17 standard). Some companies choose to quote chipset performance, which is misleading, and here's why.
