Generally popular audio equipment, it is not necessary to deliberately pursue the high quality of wire, as long as the copper core signal wire with large cross section is used.

Generally, there are several video lines to choose from, such as AV line, S-terminal line, color difference line, VGA line, DVI line and HDMI line. Color difference line is the best video line in analog signal. If the TV does not have DVI and HDMI interfaces, it can be considered, and considering the connection with the computer, an additional VGA cable can be embedded.

The audio cable is used to connect the audio source equipment and the power amplifier, so it is basically unnecessary to consider when wiring, because the audio source equipment and the power amplifier are generally put together and can be configured later.

In terms of wires, there are audio wires, coaxial wires and optical fiber wires. There are often two audio lines, divided into left and right channels, using shower heads. Coaxial line is used to transmit multi-channel signals, with large signal volume, and connectors and wires are slightly thicker than ordinary audio lines; Optical cable is also used to transmit multi-channel signals, which is different from coaxial cable transmission carrier. The last two cables are generally used to connect the DVD player and the power amplifier.
