The adapter is suitable older devices (stereo / amplifier / headphones), which can be connected analogously to connect to a digital output, eg on a new television. Here, the converter using the included Toslink (also SPDIF) cable connected to the digital output of a TV or a stereo system and then lies to the RCA outputs of the analog tone. To operate a small power supply is (which was included) required. Such a converter is not very cheap. Should the TV equipped with a SCART connector, so you should look for a SCART to RCA adapter. Such, I also deployed. The SCART to RCA adapter (selectable for input and output) 0.70 EUR shipping has me at Amazon only EUR 0.90 excl. Cost. Said Audio Converter does what he should. We are satisfied. Likewise with the other SCART to RCA adapter.
