Y3 Parallel Dual PCM1794A D2-V2.0 Decoder Board Hifi 24Bit 192kHz Audio DAC Board (Finished Board)
Friendly Reminder:
* Gold-plated finished board: refers to a board where all surface-mount and through-hole components are fully soldered and individually tested. Once connected to power and an I²S output device, it can be used normally.
Features:
PCM1794A Chips
* The PCM1794A supports a 24-bit / 192kHz sampling rate, offering high resolution, excellent sense of speed, and outstanding transparency. Its performance across the full frequency range is commendable—especially the vocals, which are smooth and sweet. It is a cost-effective chip.
* When two PCM1794A chips are connected in parallel, both dynamic range and signal-to-noise ratio (SNR) are significantly improved, reaching 132dB. The output current doubles after paralleling, enhancing sound density. Vocals become noticeably richer, and the overall sound balance is more pleasant and easy to listen to. Additionally, the bass response is strengthened. Due to the improved SNR, the background noise is cleaner.
Parallel Enhancement
* Parallel connection of PCM1794A chips significantly improves dynamic range and SNR.
* The sound becomes more pleasant, and the sound density is also enhanced.
Balanced Circuit
* Each PCM1794A chip handles one channel independently. The truly balanced circuit ensures the two channels do not interfere with each other, producing a crisp, warm, clean, and transparent sound with excellent resolution.
Op-Amp Plug-and-Play
* To facilitate DIY upgrades for enthusiasts, all op-amps are socketed for easy swapping.
* The default configuration includes 6 pieces of 5534 single op-amps and 4 pieces of 5532 dual op-amps.
Original Capacitors for WIMA
* German capacitors for WIMA are spread across the entire board, providing clear, non-lagging imaging, with a realistic soundstage and wide frequency range.
