PRO-DSD1024-K1 High-Spec USB DAC

Product Overview

The PRO-DSD1024-K1 is a production-ready high-spec USB/SPDIF DAC reference design, enabling HiFi brands and ODMs to deliver flagship audio products with fewer chips, lower costs, and faster time-to-market. Built on the highly integrated PRO-INTERFACE-M1 module that consolidates core functions into a single chip.

Key Features

Flagship Audio Specifications

USB PCM up to 768kHz/32bit, native DSD1024 under Windows ASIO — achieving studio master-tape quality. Pure DSD path ensures zero PCM conversion, restoring true sound.

Single-Module Architecture

At the core is the PRO-INTERFACE-M1, 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.

Simplified Integration

USB bridge, DSP, and MCU functions integrated into one, significantly reducing engineering effort. Module typical power consumption is only ~100mW, leaving ample power budget for portable applications.

Fail-Safe Firmware

End users can conveniently upgrade firmware via USB DFU. Robust architecture makes over-the-air updates safe and worry-free.

Personalized Audio Control

Open dsptuner.com and users can adjust onboard DSP parameters directly in the browser — no driver installation needed, instant connection across Windows/macOS/Linux/ChromeOS.

Operating Modes

USB DAC Mode

Plug-and-play via USB-C to PC or Mac, directly playing studio masters up to 768kHz/32bit PCM and native DSD1024.

Optical DAC Mode

Receive digital audio from CD players, TVs, or game consoles via optical SPDIF, supporting up to 192kHz/24bit PCM input.

Digital Bridge Mode

Functions as a high-performance USB to SPDIF bridge, cascading high-resolution digital signals to external DACs or amplifiers.
