Sound Card: Optical Output - Information

The optical output of a sound card.

To connect small desktop speakers ranging easy sockets on the sound card completely. Do you want to but play music or other audio tracks from video through a hi-fi system, an optical output is more appropriate.

An optical output has advantages

  • In a computer, the audio data is known to be processed digitally. However, in order to convert the music in audible tones, the digital signals must be converted into analog signals. For this is the sound card of a computer, a so-called D / A converter. This then initiates the analog audio signals to the output jacks.
  • Now there is an optical output on the sound card, the signals are not converted to analog signals, but sent via a so-called optical cable to an external device. Of course, there are no quality loss.
  • When the external device is usually an amplifier, which must be equipped with an appropriate input jack. Located in the amplifier a high quality D / A converter generates outstanding sound quality.

The quality of the sound card is very important

  • In a low-quality sound card, an optical output provides no additional improvement in sound quality. So it pays not to replace cheap hardware with corresponding jacks for high quality hardware with analog outputs.
  • The same is true for the amplifier and the speakers. This must also be of high quality in order to utilize the advantages of digital signal transmission.
  • You should always be aware of the fact that a digital signal transmission does not contribute to improving sound quality. It merely reduces quality losses that occur there.

When equipped with a high-quality hardware brings an optical output of a sound card, a significant gain in quality. The disadvantages of an inferior equipment can therefore not be compensated.
