Coaxial output is the abbreviation of SONY and PHILIPS home digital audio interface, which can transmit LPCM stream and surround sound compressed audio signals such as Dolby Digital and DTS.
SPDIF is divided into coaxial and optical fibers from the transmission medium. In fact, the signals that they can transmit are the same, but the carrier is different, and the interface and the appearance of the connection are also different.
However, optical signal transmission is a popular trend in the future. Its main advantage is that there is no need to consider the interface level and impedance, and the interface is flexible and has stronger anti-interference ability.
Coaxial SPDIF is generally called coaxial input, and there is a COAXIAL logo on the back panel of the equipment. The digital coaxial interface uses a coaxial cable with an impedance of 75Ω as the transmission medium.
The advantage is that the impedance is constant, the transmission frequency band is wide, and the bandwidth of high-quality coaxial cable can reach several hundred megahertz.
The time base error of digital coaxial transmission is very small, so this transmission method has better performance on sound quality.
