Black rectangular daughter card with coaxial and optical SPDIF ports, 81.9 by 19.9 by 18.6 by 121mm

Yingshan

Yingshan 24bit 192KHz SPDIF Daughter Card Optical Coaxial Digital Sound Card

SKU CH-1MKM-6RC57

A daughter card adding 24-bit 192 kHz optical and coaxial S/PDIF output with over 120 dB signal-to-noise ratio

  • Pure digital output at 24-bit 192 kHz for studio-grade audio fidelity
  • Signal-to-noise ratio and dynamic range exceed 120 dB for clean, detailed sound
  • Supports high-bit-rate and multichannel formats for versatile playback options
  • Digital transmission offers excellent anti-interference performance for stable signal integrity
  • Optical fiber connection avoids grounding issues and electromagnetic interference

Daughter-card SPDIF output for desktop PCs

The Yingshan daughter card adds pure digital audio output to a general motherboard. It delivers 24bit 192KHz resolution with signal-to-noise ratio and dynamic range over 120dB. The card supports high bit-rate multichannel formats through coaxial and optical SPDIF inputs. It suits users who want studio-standard digital audio from an internal expansion board.

Digital transmission avoids ground-loop noise

Optical fiber transmission eliminates grounding issues and electromagnetic interference in normal use. The pure digital path keeps the signal clean from the motherboard to an external DAC or receiver. No analogue stages are present on the board, so the card itself adds no audible noise or distortion. Power draw is limited to the motherboard header it connects to.

Compact PCB bracket with short internal cable

The black PCB measures approximately 81.9 by 19.9 by 18.6 by 121mm and includes a 20mm cable for the internal connection. It mounts as a baffle bracket at a rear expansion slot, providing coaxial and optical ports externally. Build quality is basic PCB construction; the short cable limits placement flexibility in larger cases. Buyers who need analogue outputs or a full-size sound card with DSP features cannot use this product.

Questions about this item

How do I install the Yingshan SPDIF daughter card on my motherboard and which step is commonly missed?

Mount the card on the motherboard SPDIF header, connect the 20mm cable, then fit the 81.9 x 19.9 x 18.6 x 121mm baffle to the rear I/O slot; the step often missed is securing the baffle screws before tightening the header connection.

What maintenance or replacement will the Yingshan 24bit 192KHz sound card need over time?

The PCB has no moving parts or consumable components; only the optical and coaxial ports may collect dust, so occasional compressed-air cleaning is the only upkeep required.

What limit appears first during sustained high-resolution playback on this daughter card?

The 120dB signal-to-noise ratio and dynamic range ceiling is the first hard limit encountered during continuous 24bit 192KHz output.
