Description

A Portable Hybrid Interface with Stellar Performance

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.

The 624 follows suit, packing top-notch sound, impressively low latency, and ample I/O into a portable half-rack enclosure. Renowned ESS Sabre32 DAC technology delivers 123dB of dynamic range, ensuring the 624's analog audio quality can hang with the most impressive gear on the market. Optimized drivers yield round-trip latency as low as 1.6ms at 96kHz via Thunderbolt and 1.9ms via USB. Packed with connectivity, the 624 includes 8-in/8-out of analog I/O with two stellar microphone preamps, two hi-Z guitar inputs, 4 x 6 line ins/outs, and a stereo headphone output. The 624 also supplies you with eight channels of digital I/O via ADAT.

The MOTU 624's built-in digital mixer delivers large-console-style mixing with 48 channels, 12 stereo buses, and 32-bit floating-point effects processing, so building complex, latency-free routing schemes is a piece of cake. And routing is extremely flexible — send any input to any output, or even multiple outputs. Add Classic Reverb, with lengths up to 60 seconds, sculpt your sound with a 4-band British parametric EQ, and apply vintage compression that's modeled after the legendary LA-2A. The 624's mixing and effects DSP engine exhibits virtually unlimited headroom and outstanding sound quality.

If you connect a wireless router to your 624, you can access all of its internal mixing functions, including effects and processing on your tablet, smartphone, or laptop, turning this powerful audio interface into a fully capable standalone mixer. Best of all, the control software is web-based. It runs in your favorite web browser on Mac, Windows, Linux, iOS, or Android — basically anything — as long as it's on the same network.

Another extremely cool use of the 624's Ethernet connection is the ability to link more MOTU AVB-equipped audio interfaces to it. You can do this in one of two ways: directly via a simple Ethernet cable or as part of an audio network via one or more MOTU AVB Switches. If you go with just a single Ethernet cable, you can easily link a second 624 or other AVB-ready device directly to your first one. With MOTU AVB Switches, you can create an audio network of up to five units, potentially linking hundreds of channels of I/O across multiple rooms. And since it's all over standard Cat 5e Ethernet cable, latency or cable runs aren't any kind of issue.
