The clutch has been appointed to the audio sound can spend the newly acquired digital receiver via a connected music system both, and without constantly back the sound of the DVD player behind the TV cable and plugs must ago. Unfortunately, the available ports are very limited, which is why I found this super solution. From the idea very well in practice, but not usable, because the losses but are too large. Once the RCA plugs are plugged into the coupling, the volume and the audio volume by significant 50% reduced. I've tried different connection paths, always the same effect. In another recession I have read that you should not connect two devices together. Although this is the case with me, but the DVD player is in standby mode. If the "common" one already under, I would have to pull back stripping and then I do not need this clutch, because then I can equal umstöpseln the cable. All in all, therefore, only 1 star.
