Aquisition made to fill a gap at Samsung. No sound output on the TV. A big flaw, the output level is really low. Electronics engineer profession, he just internally add a transistor per channel and voila. Level 20 mV to 250 mV conventional survey. Even headphones can be connected after this mod. Attention, this adapter only works with a PCM signal (no Dolby digital or other). No silent either. Buy too expensive for the results obtained.
