Eight Mic/Line Inputs for Your MTRX!

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 product. Designed for deployment in demanding professional post-production and music production environments, MTRX operates both as a high-performance 64-channel Pro Tools | HD interface and an integrated monitor section for Avid Control Surfaces.

The Avid MTRX 8 Mic Line Pristine AD Card equips your MTRX studio setup with eight channels of analog line inputs plus mic preamps with relay-based gain circuits.

Avid Pro Tools | MTRX 8 Mic/Line Pristine AD Card Features:

  • Expansion card for Pro Tools | MTRX audio interface
  • Adds 8 channels of analog line inputs plus mic preamps with relay-based gain circuits
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!
