If we talk about digital audio, at that point you have two options when we talk about choosing cables: either its Optical Digital Audio Cable to RCA or digital coaxial cables. Any of these cables will allow you to set up your theatre or audio system in digital high quality that will transmit audio signals in digital, instead of transmitting in analogue form. The quality that they will be provided perpetually be exceptionally better than RCA audio cables.
What Are Optical Digital Audio Cables and How Do They Work?
Optical digital audio cables are like other coaxial cables such as the cable TV that is connected to your TV, and these cables work on the same basic principle. They consist of an inner conducting layer that is usually made of copper. An external conductor encloses this layer along with rubber insulation that wraps outside part of the cable. The digital audio signal passes through the inner conductor, whereas the outer conductor generally is known as aluminium foil prevents interference and loss.
Quite different from RF coaxial cables which transmit both things audio as well as video, whereas optical digital cable has one purpose only they transmit digital audio in between two components. As these cables work only on a single function which provides very high quality if compared with RF coaxial cables, which helps in minimizing signal loss and interference.
What Are the Benefits of Optical Digital Audio Cables?
Apart from providing very high quality, these optical digital audio cable offers numerous other benefits also. In the typical scenario, a digital signal which is sent from the component like a DVD player it is first transfer to a Digital-To-Analog converter (DAC) that, as its name describes it converts the digital signal to analogue signal. This analogue signal passes through the medium, i.e. the cable to another component such as TV or speakers which can go from Analog-to-Digital converter (ADC) and turns signal back to analogue. This double-conversion such as transferring digital signal to analogue signal and turn back results in significant quality loss.
With an Apple Lightning to RCA Audio Cable that is both digital coaxial cable as well as optical digital audio cable, the audio signal can transmit through a digital medium, which helps in reducing and saving the use of the DAC and the ADC. Thus, the signal which is converted can bypass the receiver and provide a clear, high-quality digital signal.
