MOTU M64

The MOTU M64 is a flexible MADI interface, router, repeater, splitter and converter with AVB-TSN networking, purpose-built for moving large MADI streams around studios, installations and live rigs. It connects to a Mac or PC over class-compliant USB 2.0 or to an AVB network over Ethernet, with ultra-low round-trip latency around 1.7 ms.

The M64 provides 64 channels of optical MADI and an independent 64 channels of coaxial BNC MADI — with a duplicate BNC output for splitting — for 256 total channels of I/O. Convert optical MADI to coax, route any input to any output, and bridge MADI to and from the computer and AVB network. Word clock I/O and a front-panel headphone output round out the connections.

A 32-bit floating-point DSP engine drives a 48-channel console-style mixer with 7 stereo aux busses, 3 groups and access to 64 network inputs, plus modeled British EQ, LA-2A-style compression and classic reverb. Control everything from the MOTU Pro Audio Control web app over Wi-Fi, run the M64 standalone, or join it side-by-side with another MOTU half-rack unit using the included bracket kit.

Introducing the MADI / USB / AVB-TSN Ethernet audio interface with DSP and mixing
The M64 is a flexible MADI interface, router, repeater, splitter, converter and mixer with AVB/TSN networking. It is ideal for routing MADI digital audio streams in live performance systems, network installations or recording studios of any size.

256 channels of MADI I/O
The M64 delivers optical MADI (64 channels in and out), plus independent coaxial MADI (64 channels in and out) with an extra duplicate BNC output, in all standard formats and sample rates.

High-performance computer connectivity
New, optimized drivers for both Mac and PC deliver ultra-low latency performance. With a high-performance DAW such as Digital Performer, the M64 delivers an astonishing round trip latency (RTL) of 1.70 ms (milliseconds) on OS X and 1.71 ms on Windows over USB (at 96 kHz with a 32-sample host buffer).

The ultimate MADI converter, router, splitter and repeater
Send any input to any output, or split to multiple output channels. Convert optical MADI to coaxial MADI. Route MADI streams to and from the computer, plus any devices on the AVB/TSN network.

DSP mixing and effects processing
The M64's 48-input digital mixer delivers 7 stereo aux busses, 3 groups, access to 64 network inputs, and DSP effects, including classic reverb, EQ modeled after British analog console EQs and compression modeled after the legendary LA-2A compressor. If you know your way around a large-format mixing console, you'll feel right at home. With 32-bit floating point processing, the M64's DSP engine delivers virtually unlimited headroom and the utmost in sound quality.

Stand-alone operation with wireless control
Connect an Apple® Airport™ or other Wi-Fi router with a standard Ethernet cable for wireless control of device settings, powerful 48-channel mixing and DSP effects.

Web app control from any device - Control everything from your laptop, tablet and smartphone
The software that you use to control the M64 doesn't reside on your hard drive. It's a web app served from the hardware itself. This means you can control the M64 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.

Touch Console - The art of the mix on your touchscreen
Designed specifically for touchscreen operation, Touch Console™ delivers a whole new mixing experience. Access Touch Console from your tablet or smartphone to effortlessly control the powerful 48-channel mixer and effects in the M64. With large targets for your fingers, multi-touch operation and intuitive design, you can tap, swipe and pinch your way to a perfect mix, every time.

Comprehensive Metering
The full-color LCD lets you view all signal activity at a glance with detailed metering for all I/O. Access hardware settings from a simple and convenient menu.

Word Clock
Standard word clock input and output allows you to resolve the M64 to other digital audio gear or house sync.

Convenient headphone monitoring
Use the assignable front-panel headphone output with volume control to monitor any stereo channel pair.

Mix and match with other MOTU gear
An included mounting bracket kit joins the M64 side-by-side with any other MOTU half-rack unit to create a single rack-space configuration consisting of customized analog, digital and/or MIDI I/O configuration tailored just for you.
