The Electronic Music Box
Ultra-low latency and proven, high-performance MOTU drivers
The best possible latency performance
The 8A delivers round-trip latency (RTL) performance as low as 1.6 ms at 96kHz
over Thunderbolt™ — and an astonishing 1.9 ms over USB — with high-performance DAW hosts.
Mobile operation and universal connectivity
Ultimate portability and flexibility
Connects to your computer with Thunderbolt™, super-speed USB 3.0 or AVB/TSN Ethernet — with support for up to 256 audio channels (128 in and 128 out). USB audio class-compliant firmware and high-performance, industry-standard drivers work with any audio apps. Connects to your iPad™ with a standard camera connection kit (adapter).
DSP mixing and effects processing
Console-style mixing with 48 channels and 12 busses
The 8A's full-fledged 48-input digital mixer delivers 7 stereo aux busses, 3 groups, access to 64 network inputs, and DSP effects, including reverb, 4-band EQ, gate and compression. If you know your way around a large-format mixing console, you'll feel right at home. If you've ever wished to mix on a large console, the driver's seat is now yours.
Flexible matrix routing and splitting
Route your audio anywhere with one-click ease
Send any input to any output, or multiple outputs. Includes routing to and from the computer, plus any devices on the audio network.
Web app control from any device
Control everything from your laptop, tablet and smartphone
The software that you use to control the 624 doesn't reside on your hard drive. It's a web app served from the hardware itself. This means you can control the 624's on-board DSP, mixing, device settings, and network audio routing from your favorite web browser on a laptop, tablet or smartphone connected by wire or Wi-Fi to your local area network. Use any web client on any platform — Mac, Windows, Linux, iOS, Android — as long as it shares the same network.
Comprehensive metering
View all I/O activity at a glance — in full color
The full-color LCD lets you view all signal activity at a glance with detailed metering for all analog and digital I/O. Access hardware settings from a simple and convenient menu.
System expansion
Expand your system with more I/O and Wi-Fi control
Add a 2nd MOTU AVB-equipped interface with a simple CAT-5e ethernet cable.
Connect up to five MOTU interfaces using a
MOTU AVB/TSN Switch (sold separately).
Build a network with multiple interfaces and computers using standard AVB/TSN switches and network cabling, with ultra-low network latency, even over long cable runs (100 meters point to point). Stream hundreds of audio channels among devices and computers on the network.
AudioDesk
Powerful audio workstation technology for Mac and Windows
Includes AudioDesk workstation software for Mac and Windows with 24-bit recording, sample-accurate editing and 32-bit mixing and mastering
