Audio Quality Enhancement
Compared to onboard (integrated) sound cards, the independent sound card offer the following improvements:
* Lower background noise
* Improved detail resolution – Hear more musical nuances in the same track.
* Greater sound fidelity – Better emotional expression and a more pleasant, natural tone.

Immersive Surround Sound
* The sound card's optical and coaxial outputs support digital bitstream output, compatible with DTS and Dolby (Windows system required).
* Built on years of audio engineering experience and real user feedback, this listening-focused multifunction audio card uses digital signal processing to help you easily recreate a cinema-like or concert hall soundstage at home — delivering a pure, clear, and powerful audio experience.

Protect Your Audio Equipment
* The sound card features refined audio signal processing and control to ensure clean output and stable frequencies, while greatly reducing electromagnetic interference.
* It helps enhance audio quality, protect speaker components, and assist in audio conditioning and speaker break-in.

Enjoy High-Quality Music
* For sound testing, we recommend using high-quality audio files with larger file sizes, as these preserve more sonic detail and are better for evaluating your audio system's performance.

Usage Scenarios
* The sound card is ideal for watching movies, gaming, and listening to music, allowing you to enjoy clean and high-fidelity sound.

PC Settings:
1. About Speaker:
* When you select "Speaker Output" on the computer, it controls the two 3.5mm audio output ports of the sound card. The DSD output from the sound card is also through these two 3.5mm ports.
* The HiFi 3.5mm output is tuned for vocals, and users can also change the op-amp to modify the sound signature.
* If there's no external DAC, speakers or headphones can be connected directly to the two 3.5mm ports on the sound card — these are decoding output interfaces.

2. SPDIF Output:
* This controls the optical and coaxial digital audio outputs of the sound card. Both ports output simultaneously and transmit bitstream-encoded audio sources.
* The highest sampling rate for standard PC digital output is usually 24-bit / 192kHz. To play audio sources at this sampling rate, an appropriate player (e.g., Foobar2000) must be installed.
* To play DTS or Dolby audio, the sound card's optical or coaxial digital output must be used. When playing stereo content, it outputs stereo; when playing 5.1 audio, it outputs 5.1; and for 7.1 audio, it generally outputs 7.1. The PC system also requires a compatible media player when playing multichannel audio above 5.1.

About Sampling Rate:
After installing the driver, the sound card no longer allows sampling rate adjustment from the computer settings. Anyone who uses DSD knows that a music player (such as Foobar2000) is required, and it must support exclusive output.

The maximum sampling rate supported by the operating system is 24-bit/192000Hz. However, DSD audio files are much higher:
* DSD64 is 2,822,400Hz — 14.7 times the 192000Hz rate
* DSD128 is 5,644,800Hz
* DSD256 is 11,289,600Hz
* DSD512 is 22,579,200Hz

According to our sound card's digital chip and DAC, DSD512 is theoretically supported. However, in our internal tests, we only verified playback for DSD64, DSD128, and DSD256. DSD64 and DSD128 playback is perfect. DSD256 playback varies — some computers work fine, but others introduce background noise. This issue may require longer-term parameter testing. As for DSD512, we haven't found a suitable audio source for testing. Also, DSD512 places extremely high hardware demands — even the oscillator likely needs to be a true femtosecond clock to drive it properly.

Foobar2000 Playback of True DSD Audio: 1. Output must be set to ASIO (not something like "ASIO+DSD"). 2. Under SACD settings, choose DSD output mode.

Supported Systems:
* For Microsoft Windows XP/Vista/Windows 7 (32-bit, 64-bit)/Windows 8 (32-bit, 64-bit)/Windows 8.1 (32-bit, 64-bit)/Windows 10 (32-bit, 64-bit)/Windows 11 (32-bit, 64-bit), iOS, macOS, HarmonyOS, Daphile OS, Windows Server, China-made Kylin OS, Linux, etc., it supports driver-free operation. Windows systems can also be used without drivers.

Packing List:
* 1 × Internal Sound Card DAC
    
Packaging Details:
* Weight: 0.5kg

Note:
* There is no microphone input.
* The sound card specifically designed for listening only — it does not support singing, live streaming, or recording!
* The 3.5mm interface usually provides better vocal clarity. The coaxial output offers better audio resolution. The optical output is cleaner and more resistant to interference (usually preferred when there is interference from the graphics card).
