Digital Audio
When it comes to digital audio, you have two options when it comes to selection of cables: digital optical audio cable or digital coaxial cables. Anyone is cable to configure your home theater or audio system, high-quality digital audio to send signals to digital rather than analog form. Quality whenever you are always better than the RCA audio cables.
What digital coaxial cable and how they work?
Because coaxial cable of another type (eg cable TV cable connected to your TV), cables to use the same basic principles. They have an inner conductive layer often brass. Layer is surrounded by a driver outer rubber insulation surrounding the cable outer. Digital audio signals travel through the inner conductor while the outer conductor (usually aluminum foil) to avoid interference and loss.
Unlike common RF cable center offers both audio and video, coaxial cable digital only has one purpose: to send the digital audio between the two components. Of course, a feature that will provide higher quality RF coaxial cable, minimizing signal loss and interference.
What are the benefits of digital coaxial cable?
Besides the higher quality of digital coaxial cable provides, has some other advantages as well. In most cases, a digital signal from one side and a DVD player is first sent to one of digital to analog (DAC), as the name suggests, the digital switch analog signals. This analog signal traveling through the medium (ie, by cable) with other components (eg TVs and speakers) that has an analog-digital converter (ADC) that converts analog signals. Needless to say that this double conversion digital signal to analog and back resulting in significant loss of quality.
With a digital audio cable (ie both digital coaxial cable and glass optical digital audio cable), the audio signal can travel through a digital medium, thus saving the use of the DAC and ADC. They can therefore ignore the signals from the receiver and provides a clear and digital quality.
You can find these cables in almost all modern entertainment devices, from home theater system with DVD players, high definition televisions.
