The Zen Quadro sets a new benchmark in modern audio interface technology by combining high-quality components at an affordable price and in a portable, bus-powered format. Utilizing AD/DA converter chips from Antelope Audio's flagship Galaxy series and console-qualified discrete preamps with 75dB gain, the Zen Quadro delivers the uncompromising sound quality prized by leading recording studios worldwide.

Synergy Core real-time effects processing and advanced standalone functionality are just some of the additional features, while the innovative dual USB design allows simultaneous output and recording to two systems - a clear choice for aspiring producers, musicians and streamers looking to enhance their production environment.

The Zen Quadro Synergy Core offers state-of-the-art converters with up to 130dB dynamic range at 24-bit/192 kHz, outperforming devices costing many times more. Together with Antelope Audio's proprietary 64-bit AFC™ clocking technology, the interface delivers outstanding depth of detail in your recordings and a wider soundstage for an exceptional stereo image in audio playback - so you can make the best decisions for your Mix.

The Zen Quadro's four discrete preamps feature a 6-transistor topology inspired by the British and American analog console designs of the 1980s and 1990s, offering maximum noise reduction and precise sound pickup. With extremely low noise and up to 75dB gain, the Zen Quadro can handle even the quietest dynamic and ribbon microphones.

Antelope Audio combines DSP with FPGA chips to model every single component of the analog Hardware. This ensures sound and behavior that is virtually indistinguishable from the real thing - with almost zero latency and no strain on your computer's CPU.

Zen Quadro comes with 37 legendary compressors, EQs, guitar amps and cabinets, modulation effects and more that can be applied in real time while recording, streaming or performing live. Up to 48 monophonic effect instances can be loaded simultaneously on 6 input chains, bringing the power of a complex multirack setup to your desktop.

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

The Zen Quadro's dual USB-C ports open up a new world of possibilities for creators of all kinds. You can freely route signals and create mixes between the two USB connections by using Mac, PC, iOS (USB-C) or Android devices together. The handy loopback function is great for streaming, and the secondary port can charge your mobile device while the primary port provides power to the Zen Quadro.

Take the Studio on tour with bus-powered USB-C connectivity and a rugged metal enclosure. With full standalone operation, you can easily access routing and mixer controls via the color display and recall settings and real-time effects chains, ideal for live performances. The secondary USB-C port even enables collaboration between duo live acts using two computers on stage!

Four mic/line inputs, two instrument inputs, ADAT input and S/PDIF I/O are available to accommodate up to 14 inputs simultaneously. In addition to the monitor outputs, you also get an additional pair of line outs to connect a second pair of speakers or use them for external processing. The second headphone output has an independent mixer so that two people can listen to different cue mixes at the same time. The DC-coupled inputs and outputs can also send and receive control voltage (CV) signals, making the Zen Quadro part of a modular synthesizer setup.
