Audio Cable Use High Quality Sound Line Oct 20, 2017

Balanced transmission is a widely used audio signal transmission mode. It uses the principle of phase cancellation to minimize other interference in the transmission of audio signals. It needs to coordinate three wires to achieve, namely grounding, hot, Lengduan.

Transmission line Of course also have to be 2-core 1 shielding layer line, because the hot end signal line and cold end signal line in the same shielding layer is relatively close, so the transmission process of other interference signals are almost the same.

However, the phase of the transmitted heat-end signal and the cold end signal is reversed.

, the input end of the next level device subtracts the heat end signal from the cold end signal, the same interference signal is cancelled, and the transmitted signal is not lost because of phase contrast. Therefore, the balance transmission method is usually used in the professional situation and the transmission distance is quite far.

Unbalanced transmission only two terminal signal end and grounding end, in the requirements of low and near-distance signal transmission of use, such as home sound system. This connection is also commonly used in instruments, electric guitars and other equipment.

The Audio Cable is used to connect the sound source device and the power amplifier. Good quality of the market sound line, its production materials are mainly gold-plated, silver, copper oxide, non-metallic carbon higher to import lines, but its price is more expensive, the general need to hundreds of yuan a root, mainly the United States Monster Standrdinterlink (Monsters), Audio0uest ( Line St), supra (turtle fish), M0niterpc (Magic), space&time (hyper-temporal), MISSION (bel canto), Patrdnics (Belli), VDH (Netherlands-Van Denghao) and so on. For the general universal type (million yuan below) of the audio equipment need not deliberately pursue the high quality wire, as long as the use of general section larger copper core signal line can be. For better home theater audio equipment, you can consider the use of high-quality Audio Cables, such as DVD video and "AC-3" decoder has fiber output, input interface, such as the use of fiber transmission lines, it can improve the timbre of the more obvious role.

Audio Cable: A set of Audio Cables are often two, divided into about two channels, the two ends of the line are Lotus Head (RCA head).

Coaxial: For transmission multi-channel signal (Dolby AC-3 or DTS signal), similar to the Audio Cable, because the signal volume is large, connectors and lines are thicker than ordinary Audio Cables, generally used to connect the DVD player and amplifier.

Fiber optic cable: Also used for the transmission of multichannel signals (Dolby AC-3 or DTS signals), for the connection between DVD player and amplifier machine.

Microphone Cord: A two-core coaxial line used to connect the amplifier to the microphone. At present, the rise of wireless microphone, if not for special consideration, wiring can not be considered, after the wireless microphone application will certainly be more and more widely.

Audio Cable in the wiring when the basic need not consider, because the sound source equipment and power amplifiers are often put together, these lines are very short, late configuration can be.
