Smart TVs only have digital audio output, and traditional speakers only have analog audio input, what should I do? This little gadget can help you out

        Smart TV has become a must-have home appliance for modern families. It can not only play high-definition video, but also connect to the Internet and enjoy various online resources. However, the sound quality of smart TVs often cannot meet our requirements, especially for users who like to listen to music or watch blockbuster movies, the built-in speakers of smart TVs seem powerless. At this time, we want to output the sound of the smart TV to an external speaker to enjoy a better listening experience.

        However, here comes the problem. Many smart TVs only have digital audio outputs, while many traditional stereos only have analog audio inputs. These two interfaces are incompatible, and direct connection has no sound. So, how do we solve this problem?

Digital Audio Converter and Coaxial Audio Cable

        In fact, the method is very simple. All we need is a digital to analog audio converter. This is a small, usually inexpensive and readily available device that converts a digital audio signal to an analog audio signal. Its principle is to decode and convert digital audio signals to output analog audio signals, so that our traditional speakers can play normally.

        So, how to use this audio converter? We only need to prepare the following things.

        01. A coaxial cable, used to connect the digital audio output interface of the smart TV and the coaxial input interface of the audio converter or connect with a S/PDIF optical fiber audio cable.

        02. A 3.5mm audio to red and white RCA (lotus interface) audio cable, used to connect the 3.5mm analog audio output interface of the audio converter and the analog audio input interface of the stereo or connect with a double-ended red and white lotus head audio cable .

        03. A power adapter (generally the manufacturer will distribute it when you buy the converter) is used to supply power to the converter.

Digital Audio Converter Interface Description

        The specific connection steps are as follows

        01. Insert one end of the coaxial cable into the digital audio output interface of the smart TV (usually the RCA lotus interface marked as S/PDIF or Coaxial), and insert the other end into the coaxial input interface of the converter; if the TV has an optical fiber output, then Connect one end of the optical fiber audio cable to the optical audio output interface of the TV, and the other end to the optical audio input interface of the audio converter.

        02. Insert one end of the 3.5mm audio to red and white RCA audio cable into the 3.5mm analog audio output interface of the converter, and insert the other end into the left and right channel analog audio input interfaces of the stereo respectively.

        03. Plug the power adapter into the converter's power connector, then into a power outlet.

        04. Turn on the smart TV and stereo, select the appropriate input source and volume, and you can enjoy high-quality sound.

        After the connection is completed, it will be as shown in the figure below

        In this way, we can connect the digital audio output of the smart TV to the stereo with only analog audio input. However, this approach has some limitations, such as:

        The quality of the converter will affect the reproduction and clarity of the sound, so we need to choose an audio converter with a good brand and performance.

        Coaxial cable and 3.5mm audio to red and white RCA audio cable will also affect the sound transmission effect, so we must choose good quality cables.

        Converters require an additional electrical outlet, potentially adding to power load and clutter.

        The above is how I introduced to you how to connect the digital audio output of the smart TV to the traditional stereo with only analog audio input.
