Today's high-quality transmission of audio and video cables at a glance
2023-06-20
No matter which playback device you are using, connecting the cable is a very important link, no wonder many audio brands have launched Hi-End level USB cable, AES cable, etc. in recent years. As the audio output interface of personal computers is still dominated by the USB interface, so some decoders (DAC) and digital converters (DCC) currently on the market, are configured with a USB interface, with XLR balanced port AES output specifications of the product is still relatively small. In addition, Apple devices are equipped with Fireware line and many display cards have HDMI interface. The following will introduce you one by one.
AES digital cable
This is the transmission method used by AES (Audio Engineering Scociety) and EBU (European Broadcaster Union), AES / EBU uses XLR three-pin connector, and digital coaxial cable is different from BNC or RCA. However, except for the connector, it looks almost identical to the same type of digital coaxial cable, and the output impedance is 110Ω, which is also different from the 75Ω of coaxial cable. Although it can effectively eliminate noise interference, suitable for long-distance transmission, sound field, dynamic, and better performance in low and medium frequencies than coaxial cable, but the wire (including connectors) is more expensive, specifications are less popular, and generally less common in audio equipment.
