SPDIF (Sony/Philips Digital InterFace) is a digital audio interface standard, which is jointly formulated by Sony and Philips. SPDIF is mainly used to transmit audio signals.
There are two transmission methods for SPDIF signals, namely coaxial and optical fiber. Coaxial SPDIF uses electrical means to transmit digital audio signals, while optical fiber SPDIF uses optical means to transmit digital audio signals. Both transmission methods have their own characteristics and are suitable for different application scenarios.
The transmission distance of the coaxial SPDIF signal is relatively short and is generally only suitable for transmission over short distances, such as transmitting audio signals in home audio systems. The coaxial SPDIF signal has a higher transmission rate and can support higher audio sampling rates, thus providing better sound quality.
The fiber SPDIF signal has a longer transmission distance and can support longer transmission distances, such as transmitting audio signals in home theater systems. The optical fiber SPDIF signal has strong anti-interference ability, which can avoid the impact of some external interference on the audio signal and provide more stable sound quality.
The application range of SPDIF signals is very wide, including home audio systems, home theater systems, music production, recording studios, etc. It has become an important interface standard in the field of digital audio.
Coaxial only supports DoP playback of DSD64. Please confirm whether the playing music is DSD64;
Confirm that DoP is selected for DSD in HiBy Music, and 176.4K is displayed on the top when playing DSD;
Confirm that the connected device can play PCM 176.4K normally - Confirm that the channel is fine;
Confirm that the player system audio settings do not open plug-ins, MSEB, etc., which will affect DoP data and make DoP unrecognized;
Confirm that the connected device supports DoP coaxially, pay attention to the difference here and USB input - Confirm that the device supports DoP;
Using HiBy's player, the coaxial SPDIF output can be connected to my decoder with a low sampling rate, and the high sampling rate or DSD can not be sounded? (2023.4.7)
HiBy's player's coaxial output uses the 1V output standard; while some decoders use 3V input, so they may not be supported. This part is a compatibility problem and cannot be solved;
The low sampling rate can produce sound because the low sampling rate frequency is low, which does not require high signal quality, while the high sampling rate and DSD frequency are relatively high, and the signal quality requirements are also high;
Same type of problem: Using HiBy's player, the coaxial SPDIF output is connected to my decoder without sound? (2023.4.7)
How to connect the HiBy player, the coaxial SPDIF output through Type-C output? (2023.4.17)
HiBy's player pulls out the coaxial signal through the SBU pin of Type-C, so it is necessary to use the HiBy player's own Type-C to RCA coaxial wire.
