Y2 PCM1794A V221108 24bit 192kHz Decoder Board Audio Hifi DAC Board Module (Y2 Finished Board)

Y2 PCM1794A V221108 24bit 192kHz Decoder Board Audio Hifi DAC Board Module (Y2 Finished Board)

Friendly Reminder:
* The Y2 is a DAC module developed based on the PCM1794A decoding chip for TI. DSD is not supported.
* The finished board comes fully soldered and tested, with a 1-year warranty. Warranty does not cover faults caused by power supply issues, op-amp replacement, output short circuits, leakage, or other man-made damages.

Features:
Coupling Capacitors
* The DAC board uses the classic green audio film capacitors (for WIMA) with pure copper leads from Germany.
* In terms of sound performance, it delivers clarity and transparency, a clean and crisp sound foundation, good layering, tight low frequencies, and penetrating highs — all contributing to an overall improvement in sound quality.
* It blocks the conduction of digital noise into the analog signal path, maintaining signal purity and ensuring the full preservation of details, dynamics, and phase information in high-resolution audio.

Power Supply Filtering
* The application of filtering circuits directly affects the efficiency and sound quality of the entire system. It helps reduce potential device damage caused by high-frequency interference. In scenarios involving power fluctuations or load changes, filter capacitors can supply the necessary charge to maintain stable output voltage and dynamic response.

Original Gold-Series Capacitors for Nichicon
* Used in conjunction with the blue BT capacitors to jointly achieve smooth power signal processing, the gold series capacitors ensure the purity and clarity of the output signal.

PCM1794A Chip
* The PCM1794A supports a 24-bit / 192kHz sampling rate and offers high resolution, excellent sense of speed, and remarkable transparency. Its performance across the full frequency range is impressive — especially the vocals, which are smooth and sweet. It is a highly cost-effective chip.

Filter Op-Amp
* The board utilizes an active low-pass filter and I/V conversion design.
* Compared to passive resistor-capacitor (RC) structures, this approach is more effective in enhancing the system's responsiveness to audio signals, resulting in lower signal distortion and more powerful, dynamic musical performance.

4 Dual Op-Amps
* It is equipped with built-in IC sockets, allowing op-amp replacement without soldering. You can easily swap in different op-amps to match various music styles, making it more versatile and fun to experiment with.
