Antelope Audio Zen Quadro – Redefining Audio Interfaces

Experience Every Detail
With up to 130 dB dynamic range converters, you can hear every detail of your recordings. Power any microphone with console-grade preamps that offer up to 75 dB gain. Record, stream, and perform live with Synergy Core real-time FX processing, and connect two computers or a computer and phone simultaneously with USB OTG.

Introducing the Zen Quadro
Welcome to the Zen Quadro Synergy Core – a revolutionary audio interface that pushes the boundaries of modern audio technology. It combines top-notch components with an affordable price and portable design, making it ideal for aspiring producers, musicians, and streamers who want to elevate their setup.

Flagship Conversion and Clocking
For the first time in a bus-powered interface, we've implemented high-quality converters with an impressive 130 dB dynamic range – the same as those used in our flagship Galaxy units. Paired with proprietary 64-bit AFC™ clocking technology, the Zen Quadro offers unparalleled detail in recordings and an expansive soundstage for an exceptional stereo image, allowing for better mixing decisions.

Record with Crystal Clear Preamps
Inspired by the analog console designs of the '80s and '90s, the four preamps utilize Discrete 6-transistor topology for maximum noise reduction and precise sound capture. With extremely low noise and up to 75 dB gain, even the quietest dynamic and ribbon microphones can be powered without additional hardware.

Dual USB-C Ports for Versatility
The dual USB-C ports open new possibilities for creators. It's like having two interfaces in one – route signals freely and mix between two USB connections using Mac, PC, iOS (USB-C), or Android devices. The loopback feature enhances streaming capabilities, while the secondary port can charge your mobile device while powering the Zen Quadro.

Take the Studio on the Road
The bus-powered USB-C connectivity and durable metal enclosure make it easy to take your studio anywhere. With complete standalone operation, access routing and mixer controls via the color display, recalling settings and real-time FX chains, making it perfect for live performances. The secondary USB-C port even allows collaboration between two computers on stage!

Synergy Core: Real-Time DSP and FPGA Processing
Synergy Core merges DSP with FPGA chips to model individual components of legendary analog hardware. This results in sound and behavior nearly indistinguishable from the originals, with near-zero latency and no strain on your computer’s CPU. With the Zen Quadro, you can start recording instantly with 37 legendary compressors, EQs, guitar amps, cabs, and modulation effects, all applied in real-time during recording, streaming, or live performances. Up to 48 mono effect instances can be loaded on six input chains simultaneously, delivering the power of a complex multi-rack setup to your desktop.
