VIDEO The Speed of Sound
With a barely measurable round-trip latency of less than 1 ms*, it's no wonder dubbed Quantum-series Thunderbolt audio interfaces the fastest audio interfaces on the planet. Superb high-definition digital conversion and the ultra-transparent analog XMAX mic preamp design mean that your audio will always sound its best whether you're recording with or without your favorite plug-ins engaged in real-time.
