Sound travels as analog and digital (digital), with every type of transmission will have the corresponding connection as:
- Analog (AV)
- Optical (digital signal, via Optical)
- Coaxial (digital signal, via coaxial cable)
- S / PDIF (digital signal, the standard Sony / philip ancient)
- HDMI (used to transmit both audio and video)
Connect via AV (analog cable)
Cáp AV
White wire only the left speaker (Left, left speaker) and red rope just right speaker (Right). To save the people producing wire rope Yellow (Wire Photo, video) with red + white rope.
Connecting via Optical
Cáp Optical
Optical signals are wires connecting digital audio or optical cable called superconducting wire composite shell DuraFlex. Optical wires are painted a coating to keep track of signal transmission processes, reduces high frequency noise signals to the outside because this is the optical line, not the wires. In addition, because the optical line also should be no interference from the outside, and the less conductive than consumption. Earlier optical fiber is made perfect ball. Optical wires for audio transfer capabilities with the speed of light tens of thousands of times faster than coaxial wires, and sound reproduction and wide under the surface. That’s why the choice is wired Optical very reasonable when watching movies or enjoy the lively music program, bringing powerful audio experience, quality and more vivid.
Connecting via Coaxial
Cáp Coaxial
Wire coaxial cable is the coaxial audio features floor very well compared to conventional analog wire digital audio reproducing it in depth so this wire on the receiver used to listen to music according to many people, and I think is appropriate.
The first HD connections through port Optical / Coaxial quite simple. Depending on the existing connection on the first HD receiver, TV, .. that we will choose the appropriate connection type.
Connect via HDMI
Cáp HDMI
Both HDMI and optical digital audio are transmitted from the device to another device. Both are better than analog (red and white cables). HDMI and optical audio output enables the multi-channel (channel) is similar to a standard Dolby Digital and relatively cheap.
Different
The main difference is the HDMI can output audio at a higher quality, including audio standard used in Blu-ray discs as Dolby TrueHD and DTS HD Master Audio, this format can not pass through the gate optical. Besides, HDMI allows transmission of video signals. So, just one single cable, you can transfer content, including audio and video equipment, the HDMI will be the case the first choice.
HDMI can transmit over a bandwidth (audio data, images) in 1 second very large, fully meet all the requirements to watch movies, listen to music today. However, because each person’s preferences and ability to perceive sound differently in the evaluation should still have some say 2 channel lossless audio still uses analog wire is best.
