Outstanding audio quality

The Antelope recipe for great-sounding audio

When it comes right down to it, all the flexibility in the world doesn't do you any good if audio quality is lacking; fortunately, Zen Studio's Acoustically Focused Clocking delivers the most analog-sounding audio conversion we've heard, with clean transients, stunning clarity, and detail that let you really hear the attack of instruments and vocals. Antelope's renowned clocking and conversion technology, together with the custom USB technology in the Zen Studio, are the same as in the acclaimed 32-channel Orion interface — a fixture in world-class studios and the playback rigs of top artists.

  • Acoustically focused clocking
  • Stunning clarity and detail
  • Renowned Antelope conversion

Perfect for Tracking, Too

Record a small band or complete drum kit

With its outstanding audio quality, flexibility, and portability, the Zen Studio is a natural for EDM producers who work in multiple studio facilities or challenging environments to use in place of a console, but its generous I/O, 12 great-sounding mic pres, DSP EQ and dynamics, and onboard monitoring facilities also make it a logical choice for tracking a small band or multi-mic drum setup. All the audio I/O is available simultaneously, for a total of 38 input and 32 output channels, plus 24 concurrent I/O channels via Zen Studio's 24-bit/192kHz custom USB.

  • 12 great-sounding mic preamps
  • Simultaneous I/O up to 38 inputs/32 outputs
  • 24 concurrent I/O channels via USB

A ton of greatness with little compromise

I am quite impressed with the quality of the zen. In my own research and blind tests of any AD converter in this price range, the tastes are subjective but it's all a very close race and winner at the time depends on the material being ran through the units. I find the conversion to offer great stereo width, tight low end, focused clear mids and a high end that smooths out any harshness similar to running through a hardware console. Though I bypass the preamp stage when recording or using DI I have tried the units many preamp and DI inputs and they are great. The sound is very big and detailed and transparent. I had heard in the past of driver or software issues but Antelope must have cleaned those up as for me, everything was plug and play and over one year of usage I have not had one issue with the unit or drivers, nor have I had to reinstall drivers or software. The USB latency has been rather rock solid when recording and I do like the many I/O options that allows me to patch in hardware effects into the mix with ease. Antelopes proprietary software to control the units inputs and outputs is robust but has a learning curve to tackle. I personally do not use the on board DSP effects because of the separation between Antelopes software and the DAW but it seems you can either apply them in tracking or patch them in as if a hardware effect which is neat but I really wish they had vst versions instead.. they are very high quality but it just disturbs the work flow to have to use their console software outside the DAW. All in all, great unit.. I didn't even touch on the portability factor which just pushes this into its own league.

Still Loving It!

I`ve had mine for about a year now, and it`s crazy good. Never had any issues. I`m building up more of a hardware rack, and that`s where this shines vs. the Orion Studio. You see, this has 8 channels of D-Sub in, so you can use it as a converter-only. You cannot do this with the Orion Studio. Don`t get me wrong-the preamps are great, and I do use them. But sometimes you want a Neve or an API. The inserts are great too, for some light compression going in. For flexibility, this is much better than the Orion Studio.

Paradise Found

Thanks to Joe James at Sweetwater for steering me to the right tool. Joe gives up his time and imparts some great advice on what is currently the best going on to fit your needs. I do a lot of location recording and am always looking to lighten the load. He recommended this unit, and WOW was he right. My first use was doing a 7 track recording with a small orchestra and 2 different soloists. Easy to set up and plug into a macbook pro with my DAW. Worked flawlessly, sounds beautiful. I don't need the extra boxes and can depart with most of it now. I was worried about running long cables and how the phantom would work - no problems. Preamps are stellar on this thing. I wish it had more control on the box itself, but the software is pretty remarkable and no giant learning curve to understand. The amazing ins and outs makes this an all around tool for just about any engineer/recordist/artist/band. Really can't say enough good things about it.

Anything But Subtle

I don't have much to add to Ullanta's terrific review, but here goes: Normally, one considers swapping out a preamp, clock or converter to be an incremental upgrade; one expects subtle improvements over typical prosumer performance, beginning at about a thousand dollars per channel, but in upgrading all three at once with Antelope's USB 2.0 Zen Studio, I'm fully flabbergasted at the improvement in both the quality of my tracks and in my ability to hear them. The increase in focus, clarity and detail is simply stunning, even on virtual instruments and tracks recorded elsewhere. Then, when you consider that the Zen Studio features 12 preamps and can record up to 24 simultaneous channels; at under $100 per channel, it may appear foolish to buy anything else, IF you need this much horsepower, but there are a couple of caveats. First up, you can't rackmount it without an add-on kit, which takes up TWO rackspaces, because the unit runs very hot, possibly due to the hi-tech oven-controlled clock, and secondly there are some terrific extra features that are frustratingly difficult to access-a digital mixer with compression, EQ and even a great-sounding algorithmic reverb, all of which SO far can only be controlled with...a mouse. (and no scroll-wheel implementation,either) There is also no manual to speak of; basically just a quick start guide on Antelope's web site and mention of a DAW plugin that presumably will allow access to the goodies noted above from within your DAW, at some point. As of this writing, it's vaporware, so far as I've been able to determine. There is also no provision at present for managing any of this awesome firepower from a control surface, which is a doggone shame, because the unit itself provides a total of three buttons and one clickable knob, but as others have mentioned, many of these minor annoyances can and probably will be fixed in future firmware updates. Nonetheless, the Zen Studio's tremendous connectivity and awesome sound quality put it in a class all its own.
