Spdif out what is

But the maximum cable length depends on the quality of the materials used and the manufacture of the cable. The power of the transmitted optical signal is such that the maximum possible distance between the devices is also about 10 metres. These outputs are the same in terms of the quality of the transmitted signal, only in the first case an optical signal is used as the signal transmission medium, in the second case a physical signal is used.

In both cases, the audio signal is transmitted digitally and is not subject to distortion or attenuation. Unlike the analogue signal, which is distortion-prone and fades unevenly at different frequencies, the higher the frequency the more the signal fades. Similar connections for the transmission of digital audio are not numerous, one of the main tasks of such protocols is the transmission of DTS or Dolby digital multichannel audio from one device to another.

But these are protocols that combine video and audio transmission, SPDIF is purely an audio transmission format. Furthermore, the standard is based on AES3 Interconnect. It also carries 2 channels of compressed 5. It does have limits though, like its inability to support lossless surround formats.

These devices could be any range of appliances, such as a digital audio device, AV receiver, digital television, HDTV, video projector, compatible computer monitors in lieu of VGA connections, and so forth.

Fiber-optics tends to be more sensitive to damage versus copper wires even though the latter is, in turn, susceptible to attenuation and interferences from RFI or EMI. With that said, at least with SPDIF you can switch from optical to coaxial cables when an optical cable is damaged.

Dolby TrueHD vs. Your email address will not be published. Simply connect an optical cable from the digital audio, source such as a TV, and then connect that to the DAC which will then convert the digital signal to analogue, allowing the connection of your legacy equipment.

You may also find that you have an audio source that only has an analogue output such as a turntable, or media player. If you have a more modern amplifier or a sound bar that uses optical then you can still use these devices together by converting the older analogue signal to the newer digital optical or coaxial.

Should you have more than one optical signal you wish to send to your amplifier or speaker system, but do not want to have to unplug and re-connect cables each time you change device, then you can use a switch.

Various types of Lindy optical switches are available. These allow users to connect one or more input device such as an Xbox, TV or computer, and then select which device input you wish to use.
