1. Product Overview
The TOPPING D30 Pro is a high-performance Digital-to-Analog Converter (DAC) and preamplifier decoder designed for Hi-Res audio. It features advanced audio processing capabilities and versatile connectivity options.
Key Features:
- Advanced DAC Architecture: Utilizes 4*CS43198 DAC chips, providing a total of 8 fully balanced channels. Each channel of the D30 Pro is configured in parallel with four balanced channels, enhancing output capability and improving specifications.
- Ultra-Low Distortion: Achieves a THD+N of less than 0.00009%, ensuring highly accurate sound reproduction (99.99991% fidelity).
- High-Resolution USB Input: Supports DSD256 and PCM384kHz Hi-Res audio. The D30 Pro incorporates the second-generation 8-core XMOS XU208, allowing USB to support up to PCM 32bit 384kHz and native DSD256. With the help of a customized Thesycon driver (for Windows 7 and above), PCs can achieve better performance with ASIO playback. (Mac does not require a driver for ASIO).
- Coaxial and Optical Inputs: Both coaxial and optical fiber inputs support Dop DSD64 and PCM 24bit 192kHz.
- Flexible Output Options: Equipped with fully balanced XLR output and single-ended RCA output. Users can select "XLR only", "RCA only", or "XLR + RCA" outputs to accommodate various system setups.
