I'd be an old 5.1 system by ELAC in the attic and have this recently ausgemottet and want to install in my new apartment. Since the AV receiver did not have HDMI output and it would have been too complicated to reverse the polarity of all video out I am short for purchasing this product in the flash range. I must honestly say I had only the claim of a 5.1 channel receiver with HDMI OUT and min. 4 HDMI In so I connect all my devices (PS4 Apple Tv, tv) it konnteu d it should not be too expensive. I know myself very little with audio formats such as Pro Logic, DTS etc. and AV receivers in general from, do not know how to "heights" and "middle" hears and have relatively little idea of what you really need. Thus, this review is completely subjective. But what this device is pressed for a sound out of the speakers really impressive. The surround effect for movies and games is very clear and precise, the sound is generally a treat for the ears. And to controlled bass never exaggerated but always just right. I know that even from the speaker system used depends, but that sound I had not reached my old receiver is in approach. Connection of the individual components is relatively easy if you know where what belongs. The instructions are here relatively detailed information but I've also additionally a short video on Youtube looked at. Just search for "AV Receiver connection". Everything not rocket science :) It is also worth the built-in Bluetooth. Just a Smartphone, Tablet and connect wirelessly listening to music (A2DP Bluetooth profile required). What is relatively cumbersome, the operation. Schnöde text menus completely held in English and relatively unintuitive. Actually, there should also be a First Start Setup to instructions. What with me but somehow was not the case. I have therefore all set manually by feeling. Also missing the opportunity to reset the device to factory settings (or I have not found this setting) to begin again at 0. In addition, the part is very big and clunky. For me it just fits to the TV cabinet. This is not a negative thing but it should be noted just before purchase. All in all I am very happy and forgiving with 1 deduction for the service 4 stars :)
