Zen Studio Portable Audio Interface

Studio quality and functionality in a sleek easy
to carry box

Zen Studio is the professional, portable audio interface with the most competitive analog and digital connectivity. The 12 world-class mic pres, Antelope's signature clocking, the on-board DSP effects with multiple monitor mixers and the proprietary low-latency USB connectivity make Zen a world-class mobile recording system, that can easily fit inside a backpack or gear bag. Zen Studio is designed to meet the needs of the modern day producer or engineer on-the-go, as well as location sound engineers, sound designers, independent bands and musicians in search of greater sound quality and flexibility.


Proven technologies for supreme audio

Antelope Audio Acoustically Focused Clocking provides the most authentic analog sounding A/D & D/A conversion on the market. Antelope's clocking and conversion along with the custom USB technology implemented in Zen are identical to the ones in the top-selling 32-channel Orion interface which is a centerpiece in the playback rigs for artists such as Rihanna, Jay-Z and Justin Timberlake, and inside the mixing and mastering studios of engineers like Eric Sarafin (aka Mixerman), Brian Vibberts, Howie Wienberg or electronic music producers like Robert Babicz and Dusty Kid.

 Intuitive control and signal routing 
bringing unique versatility

Zen Studio is fully controllable using an intuitive desktop application on both PC and Mac, offering flexible signal routing and DSP-based effects alongside custom presets. Users can create up to four independent, zero-latency mixes assignable to any outputs, including the two independent headphone outputs and monitor outputs. All audio I/O is available simultaneously for a total of 38 possible input and 32 output channels, plus 24 simultaneous I/O channels via custom USB, supporting 24-bit, 192 kHz audio.


DSP effects and flexibility to enable
creative audio production

In addition to proven sound quality, Zen Studio offers an extremely powerful DSP, based on a custom FPGA device with massive parallel processing capabilities. The proprietary FPGA makes the DSP chip in Zen Studio eight times more powerful than the ones used in similar devices. This allows fast and easy simultaneous processing of multiple effects, enhancing the workflow like no other device on the market.


The latest addition to our multifunctional audio interface is our first reverb - AuraVerb. It creates various ambient colors, or “Auras”, using a unique algorithm to provide color and richness like no other reverb so far. Producers can easily design thickening effects, washing effects, bright halo type film score effects. There are also darkened mood effects and long, clear and rich decays - just a few of the many dimensions, which AuraVerb is able to add to the mix. In addition AuraVerb comes with reverb presets, specifically designed by the 5-time Grammy Award winning recording and mixing engineer Brian “Dr. Vibb” Vibberts.
