The Quantum-series proprietary Thunderbolt driver was written from the ground up to deliver ultra-low-latency performance while maximizing efficiency. Cutting-edge 24-bit, 192 kHz converters with 115 dB of dynamic range and superior low-jitter clocking—coupled with our ultra-transparent, pure analog XMAX preamps—result in superb audio quality with the lowest round-trip latency of any audio interface available (< 1 ms*). With a barely measurable round-trip latency of less than 1 ms*, it's no wonder Sound on Sound magazine 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.

Thunderbolt 1 and 2 require an adapter, not included.) Internet connection (required for Studio One Activation and Content download) Internal or external 7200 RPM storage drive highly recommended 30 GB hard disk space Monitor with 1366x768 resolution Note: The minimum system requirements may differ for DAWs other than Studio One. Please check the requirements for your DAW of choice with its manufacturer. Note that the speed of your processor, amount of RAM and size and speed of your hard drive will greatly affect the overall performance of your recording system. Also, a more powerful system (faster processor with more RAM) will allow for lower latency (signal delay) than you might experience while monitoring audio signals.
