Zoom Thunderbolt Audio Converter and MIDI Interface

The compact, rugged TAC-2R audio interface uses the latest Thunderbolt technology for blazingly fast speed, near zero latency and the ultimate in high-quality audio, up to 24-bit/192kHz. With its easy-to-use design and advanced converters, the TAC-2R is perfect for studio and field recording of mics and instruments, onstage playback, and pristine audio streaming. It can even serve as an ultra-stable MIDI interface.

Thunderbolt Fast!

More than twice as fast as USB 3.0, Thunderbolt is the interconnection technology of the future. Co-developed by Apple and Intel Labs, it allows signal to be transferred at an incredibly fast 10 gigabits per second, which means virtually no latency. Thunderbolt interfaces such as the TAC-2R are also unaffected by computer jitter (slight variations in timing), so there's no need to connect an external master clock source.
