Antelope Audio Discrete 4 Pro Synergy Core

Antelope Audio Discrete 4 Pro Synergy Core – professional desktop audio interface with 4 discrete preamps, 14 inputs / 20 outputs, real-time Synergy Core FX processing, 64-bit AFC clocking, Thunderbolt 3 and USB connectivity, and up to 130 dB dynamic range – a powerful solution for modern studios and mobile setups.

The Discrete 4 Pro Synergy Core delivers premium studio-grade sound in a compact interface tailored for producers, engineers, and musicians who demand precision and flexibility. It features four discrete transistor-based mic preamps inspired by vintage analog consoles, providing ultra-clean, detailed audio capture with up to 65 dB gain. Its high-end AD/DA converters ensure up to 130 dB dynamic range, while Antelope’s 64-bit AFC clocking minimizes jitter and preserves sonic depth and realism across all sessions.

This interface supports both USB and Thunderbolt 3 connections, offering up to 32 I/O channels with ultra-low latency. It includes four combo XLR/TRS inputs, four TRS line outs, two monitor outputs, four independent headphone outs, plus digital ADAT and SPDIF I/O. Dual Word Clock outputs ensure accurate sync in complex studio setups. Built-in Synergy Core processing harnesses 2 DSP chips and 1 FPGA to run up to 80 real-time effects across 16 virtual racks. The included 37 FX suite covers compressors, EQs, vintage preamps, amp sims, and more. With advanced routing, onboard mixing, and the AFX2DAW plugin for Thunderbolt users, the Discrete 4 Pro is a complete studio hub for any workflow.
