Avid MTRX HD Audio Interface: The Ultimate Audio and Monitor Interface

For our Pro Tools | HDX and HD Native users seeking off-the-charts sonic quality and extensive routing and monitor control flexibility, Sweetwater recommends Avid's cutting-edge Pro Tools | MTRX audio interface. Avid worked closely with Digital Audio Denmark in the development of this groundbreaking interface to deliver stellar sound, with support for up to 384kHz DSD audio. And you'll find it an especially versatile addition to your workflow, serving both as your audio interface and monitor control center. Designed for deployment in demanding professional post-production and music production environments, the Avid MTRX audio interface operates both as a high-performance Pro Tools | HD interface and an integrated monitor section for Avid Control Surfaces.

Avid MTRX audio interface adapts to your workflow

Avid HDX features include Eucon-controlled monitoring, extensive integrated routing, and ultra-high-quality analog input, output, and microphone preamp card options. And you can choose which combination of modular interface options you need to adapt MTRX to your studio workflow preferences. The Avid MTRX base unit gives you 16 channels of AES I/O, one coaxial MADI I/O pair, two Mini-DigiLink ports, Pro | Mon 2 Eucon monitoring capabilities, and the DADman app for configuration and remote control from a Mac or PC.

Connectivity, reinvented

Offering a total of eight interface protocol options, the Avid HDX reinvents the concept of connectivity. For analog input and output, it lets you install up to six 8-channel AD/DA cards (including 8- and 2-channel mic preamp card options) for up to 48 channels of high-quality Avid conversion. From there, the I/O options are plentiful: up to 144 channels of AES/EBU (16 channels on the chassis), an AES3 card option with 16 channels plus SRC in, up to 256 channels of 3G-SDI, 64 channels of DigiLink (using the two rear-panel ports), 64 channels of coax MADI (via rear-panel I/O), over 1024 channels of MADI (up to 192 channels on the chassis), a Dual MADI card option with up to 128 channels via SFP coax and optical I/O, and a Dante option with up to 64 channels.

Avid MTRX Audio/Monitor Interface Features:

  • Flagship Pro Tools interface with modular flexibility
  • Digital Audio Denmark AD/DA converters with support for up to 384kHz DSD audio
  • Extended monitor control and flexible routing with S3, S6, or other Eucon surfaces

  • Use DADman software to feed any input to any output, send audio to multiple outputs simultaneously, and otherwise route, split, and patch audio
  • Add high-quality mic preamps as an option, and remotely control them from Pro Tools
  • 8 x 8-channel card slots let you customize MTRX for your needs
  • Rock-solid sync via Word Clock, AES11, Video, and all digital I/O
  • Automatic sample rate conversion on inputs
  • MADI, Dante, and SDI I/O option cards available separately
What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

Reviews

Best interface ,sound quality and full features
First off I want to thank Patrick Dennis for always taking good care of me, I like to say am so happy with the sound quality , I got rid of my avocet which is the best monitor controller you can buy but this eliminated the need for that and my atomic clock 10mx , the MTRX clock is better in my opinion it sounded more open and natural the price is very high am not happy about that but , the work flow is on another level , the monitor card is so cool how you can cutomize your settings and the Dante helped me a lot as well , you need the Mom controller to control things easily , I set it up with my avid S3 to control monitor changes and source selecting and its pretty cool but when the screen was on pro tools the vol fader would not work unless I switched to DAD screen another down side to that was that I had to reprogram Eucon app every time I restart but the unit is a A beast am very happy with it I recommend it if you serious about Music production and mixing.
