Practical and compact, this converter allows for the transformation of audio signals from digital to analog. The digital signal can be received via an optical fiber cable with a Toslink connector or through a coaxial RCA cable. The output is available through both a standard RCA connection and a 3.5 mm jack. It is useful in many situations, for example, to extract the audio signal from a television to listen through headphones or to amplify it externally. A small 5V - 1A adapter is included in the package.
