Perfect
Very good product, I took this model to enjoy the auro 3D, easy to install, everything is indicated during the first installation.
The amp is powerful enough for a 22 m2 dedicated room. Good sound reduction coupled with a Klipsch set (R 820F, RC 34C, R 51M, RS 41 II, R 12SW subwoofer),
I added in order to make the most of my installation, a power amp for the R 820 F, which allowed me to put four (R41 M) in the ceiling to take full advantage of the 3D auro! It is....incredible!
A piece of advice, use the Audyssey application for a better calibration and a better sound definition.
