Metric Halo has officially certified two Thunderbolt adapters for use with their line of FireWire based audio interfaces.

The company has tested the Thunderbolt-to-FireWire adapter in the Apple 27-inch Thunderbolt Display and the Sonnet Technologies Echo 34 adapter combined with their FireWire 800 Pro ExpressCard - both systems provide performance identical to native FireWire ports. Since the display has a Thunderbolt pass-through it's possible to use both adapters at the same time, allowing the user to create two separate FireWire busses. With two busses the user can connect up to six of our interfaces, or use one for up to three interfaces and the other for hard drives.

The company also says they are in discussions with Intel to gain access to Thunderbolt technology and will be incorporating Thunderbolt into their products.
