The MOTU 624 hybrid audio interface packs high-end sound, ultra-low latency, and generous I/O into a portable half-rack unit. ESS Sabre32 DAC technology delivers an impressive 123dB of dynamic range on balanced, DC-coupled analog outputs. Experience round-trip latency as low as 1.6ms at 96kHz via Thunderbolt and 1.9ms via USB. 32 total channels of audio I/O make connecting your instruments, microphones, and outboard gear easy. An onboard DSP mixer provides latency-free routing, along with an array of powerful digital effects. Use the 624 as a standalone mixer, or control it wirelessly from your tablet, smartphone, and laptop. Both onstage and in the studio, the MOTU 624 delivers.
