A little disappointed ... 201

The installation went without much problem.
2 son pairs are provided to attach the transmitter to the audio output of the home theater.
The manual is clear and detailed enough (it is useful to make the setting)

But I am disappointed on several points:

1) We understand quickly why it is stated "Surround" in the title of the product: The sound transmitted is quite correct, compared to the FM or even bluetooth low end, but the receiver amplifier, which drives the speakers back, is bad enough!
By choosing to replace cables by this transmitter / receiver, made the choice to not drive back speaker with amp 5.1 amp kit but by the receiver, which is unfortunately pretty bad here .... damage.
This is not necessarily bad if we only use the rear speakers as surround that (hence accuracy in the title) but my 5.1 kit allows me to use my speakers as Stereo x2 it which is convenient for sound to the living room to listen to music ... in this case, it is better than the sound of the rear speakers is as good as the front, which is clearly not the case here ...
-> I do not listen to my music now with the front speakers, rear speakers and subject to surround movies / games :(

2) The transmission power or reception sensitivity appear weak, and instructions advise that the space is reached between the transmitter and receiver and are facing one side to the other if possible to same height. This is not the case for me, because of point 3, and I have regularly cuts :(

3) 2 pairs of son provided is very short! Unable suddenly placing the issuer has more than a few cm of the amp ... and difficult to meet the recommended configuration record (see point 2) Income, reception sometimes cut, causing crackling and mute.
Another detail, there is no color on these 2 pairs of son. So to connect the output "red" of the amp to the input "red" of the issuer, have to follow the thread to the end to do not mix with that of the "black" out ... 2 small color points to identify each other were practices.
To end these 2 pairs of son, tin was placed on the ends was done very roughly and I was forced to cut it so that the son could fit properly ...
In short, these two pairs of son can help, but to replace whenever possible (even more than it does not look super quality ...)
