Core Capability

Traditional HiFi DAC designs require multiple discrete chips working together—USB bridge, DSP processing, and power management as separate components—resulting in long development cycles, complex debugging, and persistently high BOM costs. PRO-DSD1024-K1 changes everything: built on the highly integrated PRO-INTERFACE-M1 module, it consolidates core functions into a single chip, enabling manufacturers to rapidly build a complete product line from desktop DACs to portable dongles—shared firmware, unified platform, dramatically reduced R&D investment.

USB DAC Mode
USB DAC Mode

Plug-and-play connection to PC or Mac via USB-C, directly playing studio masters up to 768kHz/32bit PCM and native DSD1024. Driver-free on macOS and Linux, with stable third-party ASIO drivers on Windows for ultra-low latency professional performance.

Flagship Audio Specifications

USB PCM up to 768kHz/32bit, native DSD1024 via Windows ASIO—achieving studio-master quality. The pure DSD path ensures zero PCM conversion, reproducing authentic sound that meets the most demanding audiophile standards for transparency and detail.

Single-Module Integration

Single-Module Integration

At its core is the PRO-INTERFACE-M1 (ATS3625N), integrating a 504MHz HiFi-5 DSP, USB 2.0 PHY, and PMU. This highly integrated design replaces four discrete chips, dramatically simplifying layout and reducing BOM complexity. The onboard power management unit automatically handles all voltage sequencing, further minimizing external components.

Simplified Integration

USB bridge, DSP, and MCU functions unified in one package, dramatically reducing engineering effort. The module typically consumes only ~100mW, leaving ample power budget for portable applications. Comprehensive layout guidelines ensure signal integrity, letting production units easily match reference performance.

Simplified Integration
Fail-Safe Firmware System

Fail-Safe Firmware System

End-users can conveniently upgrade firmware via USB DFU. The robust architecture makes online updates safe and reliable—users resolve software issues and access new features directly from their home computers, significantly reducing RMA rates.

Personalized Audio Control

Open dsptuner.com and users can adjust onboard DSP parameters directly in the browser—no driver installation required, working instantly across Windows, macOS, Linux, and ChromeOS. Real-time tuning of EQ, effects, and other modules with A/B comparison, all with less than 100ms latency.
