Possession of the receiver now for about 3 weeks. Predecessor was the Onkyo 509 is operated at the Yamaha 2 front floorstanding speaking and a center. A separate subwoofer does not exist, since bass (with the Onkyo) over got along very well from the front-LS to date. Purpose is listening to music in stereo or movie sound, but then incl. Center-LS. The calibration with the microphone is done in 2 minutes. The front-LS are recognized as large, the Center as small. So far so good. After recording the sound is very very underpowered. Bass are so good not to hear such. But even at heights lacks. In equalizer menu you have the choice between PEQ, GEQ and Off. Standard is PEQ in which all frequency beams to 0 (exactly in the middle) are. Here is mMn strongly advised to put on GEQ and to adjust the desired pitch or depth in the respective frequency bands. This setting is made separately for each LS. Furthermore, I unfortunately had to find that the front volume control, scrapes when turning on the edge of the recess in which he plugged along. Either the knob is not perfectly round, or the depression. But wanted him why not send it back. Here it helps to turn the knob to pull out 1-2 mm. Does not fall to continue and it scrapes nothing more. When listening Standard I choose Straight, since the sound is output as the original. Stereo is here automatically output from only the two front-LS and example. DD 5.1 or DTS is then also addressed the Center. It took me some time to calibrate the receiver correctly for me, but now everything is right. Both the bass and the treble now come across well. Finally: The Onkyo 509 predecessor offered directly after calibration is already a (for me) very good form. At Yamaha, I had to invest significantly more time to get the desired result. FYI: Just for the two front-LS screw exist, the remaining LS plug clamped. HDMI standby pass-through has not this receiver. To my knowledge, there is only from the 477er model. For the little money but recommended.
