Product purchased, like everyone else I suppose, to connect a TV without analogue output (bravo ...) to an amplifier without digital input (common in older amps or oriented "audiophile"). Most: - Discrete - Supports coax and optical - No problems with the HD channels like seem to suffer much of this type. In this regard, my TV also allows me to force the digital audio output to PCM, this can maybe save those who have concerns with dolby channels. Cons: - Only RCA output; a headphone output would not have been too much. - It is a little expensive, probably the price of some market "niche"; Nevertheless, an 20 TNT as it embeds a converter which is more or less the same ... and caught DTT also decode the video, and have a remote control. - Somewhat low output level Moreover the sound seems a little less detailed than the output DVD / BD player, for example, but it can also come from the TV.
