Avid Pro Tools MTRX 8 Mic/Line Pristine AD Card

Best, clearest sounding interface I had so far. I owned Apogee Symphony I/O, Antelope Orion, RME fireface, Avid Omni, Apollo X, etc. this is by far the best.
And the routing capability is incredible.
This is My first Avid HDX card, it makes a huge difference, tracking latency free. Rock solid.
The TB box and HDX card has some fan noise, but I don’t track in the same room.
Highly recommended

Great system, exactly what we needed for our record setup. 32+channels into ProTools via our Dante network without any issues. Our Sales rep Jeff at VintageKing was super helpful all along the way. Only issue I had was with Avid not including as standard a second mini digilink cable in with the unit to utilise the 32+ IO on the HDX card that you are paying them royally for.

Could you please explain how to get it up to 64-channel Pro Tools | HD interface..

There's little doubt in my mind, at any rate, that Digital Audio Denmark carries with them the best converters that are on the earth. Perhaps I'm ignorant, perhaps a little dim witted, embellishing and outright making false claims - yet I can attest being a singer/songwriter, to this amazing interface/converter compared to 20+ years of myself using DAW's starting out with ghetto vis a vis terrible gear. Eventually evolving towards the best. Take heed that you be aware Avid is a software company. Frankly, IMHO the 192's, 96's and the so called "new" (despite them being rather pathetically old for years and years) Avid I/O's are really poorly lacking in many respects. My point? (pardon the overly verbose nature of my writing) What you have is Avid teaming with DAD to produce the ultimate. (ie DAD produces the hardware, while Avid applies the hardware towards their software) I highly suspect, the half life of the MTRX will outshine anything for many years to come, whereby making it a very wise investment. If you really want to creme de la creme, BUY IT.
