Antelope Audio Zen Quadro Synergy Core USB Audio Interface

Quadro = 4 pro-grade mic preamps. Plus high-end conversion and clocking, Synergy Core processing power for Antelope FX plug-ins, dual USB-C ports, and more!

Zen Quadro Synergy Core. 14-in/10-out Dual USB-C bus-powered audio interface with Discrete preamps, class-leading converters, and included real-time DSP+FPGA effects. The Zen Quadro stretches the limits of modern audio interface technology by implementing top-shelf components into an affordable price and portable bus-powered form factor.

Taking the AD/DA chips from Antelope Audio's flagship Galaxy range, along with console-grade Discrete preamps with 75dB gain, the Zen Quadro provides creators of all kinds with the same uncompromising sound quality enjoyed by the world's premiere recording studios.

Synergy Core real-time effect processing and enhanced standalone functionality are only part of the additional features packed into it, while the revolutionary dual-USB design allows simultaneous playback and recording on two systems - making it a no brainer for all budding producers, musicians, and streamers looking to power up their production setup.


- High-fidelity conversion with up to 130dB headroom, paired with 64-bit AFC clocking technology for increased sound width, separation, and detail;
- Four Discrete console-grade 6-transistor preamps for crystal-clear recordings;
- Real-time Synergy Core processing, for tracking, monitoring and streaming with near-zero latency through faithful digital recreations of legendary studio equipment;
- Includes 37 effects modeled after vintage analog compressors, EQs, guitar amps, modulation effects and more;
- Dual-USB read more design, with secondary USB-C port (OTG) for simultaneous playback and recording on two systems;
- Easy access to routing and mixer settings, device control and preset recall via large color display provide complete standalone functionality;
- DC-coupled inputs and outputs for controlling synths via control voltage (CV) signals.

Unparalleled AD/DA Conversion and Clocking:

Zen Quadro Synergy Core packs the latest gen converters, with up to 130dB dynamic range at 24-bit/192 kHz, outperforming competitors at several times the cost. Paired with Antelope Audio's proprietary 64-bit AFC clocking technology, the interface provides you with a higher level of detail in your recordings and wider soundstage for an exceptional stereo image in audio playback - allowing you to make the best decisions for your mix.

Crystal Clear Preamps:

The Zen Quadro's four Discrete preamps are built with a 6-transistor topology inspired by the British and American analog console designs of the eighties and nineties, offering maximum noise reduction and precise sound capture. With extremely low noise and up to 75dB of gain, the Zen Quadro can handle even the quietest dynamic and ribbon mics.

Synergy Core: The Magic of Real-time DSP and FPGA Processing:

Antelope Audio engineers combined DSP with FPGA chips to model each and every individual component of analog hardware. This ensures sound and behavior that's virtually indistinguishable from the real thing--with near-zero latency, and zero strain on your computer's CPU.

Zen Quadro comes with 37 legendary compressors, EQs, guitar amps and cabs, modulation effects and more, that can be applied in real-time during recording, streaming or live performances. Up to 48 mono effect instances can be loaded on 6 input chains simultaneously, putting the power of a complex multi-rack setup on your desktop.

At any time, you can expand your collection with more real-time effects such as Antares' Auto-Tune Synergy and Grove Hill's Liverpool, available as additional purchases.

Revolutionary Dual-USB design:

The Zen Quadro's dual USB-C ports unlock a world of possibilities for creators of all kinds. It's like having two interfaces in one - freely route signals and create mixes between the two USB connections, using Mac, PC, iOS (USB-C) or Android devices together. The convenient loopback makes it great for streaming, and the secondary port can charge your mobile device while the primary port provides power for the Zen Quadro.
