Since 4 days the unit is in use. The default was quickly made the room measurement did not work because of a malfunctioning microphone. (There is an error in the speaker setup has been issued again and the measurement is interrupted) However, since measured not much I have everything measured out like the old days with ruler and with experimenting the crossover around, help were the existing experiences posted. The result is a better sound than my Harman Kardon AVR 255 defective and that was the goal. Not quite powerful module is likely to be because it does not find my home network, iPad and iPhone function while still perfectly, so I had to get the WiFi Extender from the basement and go with lower bandwidth, which affects the streaming the WLAN. Soon the second zone will be tried by a pre-amplifier to the Line Outs is connected and an additional analog active system is operated at a different location.
