The HD OMNI Is a PowerHouse 7.1 Surround Interface PreAmp

I mix in 7.1 Surround and this took care of all my Pro Tools 11HD needs and even has a transparent interface with the Mac Pro internal audio to have a throughput to the monitor speakers, allowing all audio from every app from the Mac to the surround mix.

Wow this sounds so nice~ I just got this and I'm telling you it's making me love working on music again. Formally coming from the Ensemble and the Mbox3, I had forgotten that how much a great converter can make a difference. Mind you, Apogee Ensemble and the Mobx3 are no slouch either. This thing is accurate, detailed and yet has a very subtle color that makes it sound so nice. It's hard to put my fingers on it but I'm loving it. I can hear more details in the mixes and also I can hear the fxs such as reverbs, delays and ambience much better. I feel like my modest Yamaha HS80m just got a expensive mod on it :) Stereo image is really accurate it kinda feels awkward still if you know what I mean. Also headphone output sounds great too. The best I've heard so far. Also unlike a lot of reviews I read online, it;s very easy to operate in a sense that "it just makes sense". Love the simple yet very functional monitor controller section. I wish Avid will hurry and come out with the remote already since there is a remote out jack in the back. I haven't tested the Mic Pres yet but I can't hardly wait. I've read that it's on the clean side but I'm hoping it's a big step up from the Ensemble or the Mbox3. We'll see. Overall I'm pretty stoked!!!

Best so far

Omni has the best sound quality I have heard so far. Im coming from Mbox 3 Pro wich I thought sounded good untill I got the Omni. I have also experience with RME UFX. Omni is head and shoulders above Mbox and UFX in sound quality. I would give it 5 stars if it had 2 headphones out,4 mic pres instead of 2 and 8 line input instead of 4. Another minus is you cant use the 4 line inputs + 2 mic pres simultaniously. Either 2 mic pres + 2 line inputs or 4 line inputs. The way I work now I can live with the limited I/O, but if I someday need more I/O I have to look for an alternative.

I'm a happy camper

A cheap way to get into HD, coming from motu interfaces I noticed a a big change in sound quality, all I'm missing is the number of I/Os, right now planning to buy some digidesign HD blues to connect to it

Sweetwater Advice

Carson McClain

The Avid HD Omni is the perfect segue from Pro Tools LE to Pro Tools HD. Aside from the power supply and a few other small internal parts, it's practically identical to the HD I/O. If you're a studio engineer, this could be a perfect addition to your rig if you need to go mobile or record and edit at home. Finally, a more scaleable solution for Pro Tools HD users!

Josh Estock

Avid's HD Omni is the perfect addition to any studio. Whether you're using it at home, on location, or in a mix room, the Omni will will definitely impress. This unit boasts it all: transparent preamps, top-notch conversion, I/O to boot. This is literally an all-in-one professional Pro Tools|HD solution in a single rackspace. What else could you ask for?
