Essential Information About the Antelope Zen Quadro Audio Interface
- High-end 24-bit/192 kHz conversion with up to 130 dB dynamic range and AFC 64-bit clock for ultra-precise stereo imaging.
- 4 discrete 6-transistor preamps, extremely low noise, and 75 dB gain to drive even dynamic and ribbon microphones.
- Dual bi-host USB-C: simultaneous recording/playback on two systems (computer + mobile) with ideal loopback for streaming.
- Synergy Core real-time platform (FPGA + DSP) with up to 48 mono effects, 37 included effects. Special offer: 25 free plug-ins with any purchase from 10/01/2025 to 12/31/2025.
Antelope Expertise in a Bus-Powered Format
Zen Quadro follows the "Zen" interface line by bringing the conversion quality of the flagship Galaxy series to a bus-powered desktop format. It incorporates Antelope's expertise in digital clocking and jitter management to deliver a wide soundstage, clear transients, and reliable mix tracking without external power.
Who Is It For? Mobile Producers, Project Studios, and Content Creators
Designed for lightweight multitrack recording, advanced podcasting, and professional streaming, Zen Quadro combines powerful preamps, precise monitoring, and versatile connectivity. The dual USB-C allows connection to two hosts (Mac/PC and mobile device) for co-streaming, playback of assets from a smartphone, or separating guest/music feeds, while integrated loopback simplifies broadcasting.
Features and Innovations That Make a Difference
Reference Conversion and Clock
High-performance converters paired with the AFC 64-bit clock provide an unusual level of detail for a bus-powered interface: more confident recording and mixing decisions, stable stereo image, and increased depth.
Dual Bi-Host USB-C
Like having two interfaces in one: freely route signals between two USB connections, blend them in internal mixers, and charge your mobile device via the secondary port while the primary port powers the interface.
Discrete Preamps Inspired by Large Consoles
Four discrete 6-transistor stages offer headroom and musicality, with 48 V phantom power and generous 75 dB gain to capture demanding sources without external boosters.
Synergy Core Real-Time and Standalone Mode
The FPGA + DSP duo processes up to 48 mono effects with extremely low latency. In standalone mode, recall effect chains and control routing directly from the built-in screen: convenient for stage or mobile sessions.
