The Teach to the existing remote control (Logitech) was carried out directly and without further problems.
The criticized elsewhere sound dropouts during TV reception I can not confirm as caused by DHT-T100. This occurred to me previously and I suspect that they are already created on the digital TV transmission path (z. B. bit errors). This also relates to the sound and the dynamics of the transmitted audio signals. Herein, the TV channels are different in some cases substantially, so that will not be caused by other alleged loss of sound in my opinion, from the DHT-T100. Once a TV station offers a reasonable dynamic range, plus it is also very well represented by the DHT-T100. Here then also the different sound modes making their presence felt.
On the Bluetooth connection I have also nothing to complain about. Range and dynamic range are from the source device-dependent. Already with a Samsung Galaxy as the signal source I could round the whole room go without dropouts or loss of sound could be seen.
Finally, a little icing on the cake: The manufacturer has even thought of a Velcro strip for the excess length of the power cord.
I am completely satisfied and recommend the unit be happy.
