Both in the product description on Amazon.com and on teufel.de will "never again clutter" spoken of. That the Rear Station 4 both current (ie a socket) and cables are required to connect the surround speakers, is not mentioned! Since there are far cheaper suppliers with significantly better systems that really get along wirelessly!
Of course, I needed a new surround amplifier to my new surround system. Since I am not an expert, uch chose the test winner of a magazine, the Onkyo TX-NR 509. When all was as it turned out, that it is not feasible without further ado, to connect the wireless station from hell. In a telephone conversation with the devil was told, the Onkyo 509 is fundamentally incompatible me to the order me 709, and referred me to a compatibility list on teufel.de that needs to be about 5 years old, however. The 709 but costs 200, - and more, with the difference of 5.1 to 7.1, the devices look identical from. I opted for Onkyo ask. The staff there was immediately clear competent and told me, there is an adapter for about 15, - he indeed can not offer, which is available but to buy the accessories, so everything works. Since then I have retold devil. The offer this adapter to even, but told me in my particular case it is not compatible, I need another amp ... I was about to send everything back. Frustrated, I decided that 15, - for the adapter to invest and if it does not work to send everything back. Lo and behold, the system works properly !!!
Conclusion: devil there is nowhere to even listen to sample, there is only the direct sales. The telephone consultation is therefore the only way to ask directly and must be properly, but it is not. It has been wrongly advised me several times! This is not acceptable at this price! To make matters worse still missing at the end of the power cord from the subwoofer. In a response from the devil, of course I complained, I wait until today!
