Modern D+M AVRs and pre/pros have a very user-friendly "setup assistant". It'll lead you through connecting your speakers and input devices and running the Audyssey calibration procedure. For example, all of the speaker outputs are connected by individual electro-mechanical relays which the setup procedure makes use of when it tells you to connect a particular pair of speaker wires. This helps to isolate wiring problems.
(Unfortunately, there are some bugs related to overhead speaker calibration in the initial release, so you probably should run it again after it has helped you configure the network and download the current firmware update.)
Also, please take the time to read the Audyssey 101/FAQ
(<-- this links to the FAQ). Their recommendations have been developed over a long period of time to help you get the best results. The instructions provided in AVR manuals are woefully inadequate.
I have my old trusty 5803 with a simple set up , not too complicated and I have had wonderful sound out of it all these years .
Unfortunately , it needs to be upgraded in order to get 4K HDMI connections , Dolby True-HD , Atmos, etc , so that is why the 7200W is coming to play .
Now, having said that , I think that perhaps I will be having some problems with the way I have my subs set up and this "Audyssey thing" on the incoming receiver ...
I have my speakers on "large" (all of them) and the two subs on LFE+Main and I do get plenty of very low bass on the subs . BTW, the subs are in "auto " and they turn on instantly .
"Plenty of very low bass" is not necessarily the same as "accurate bass". In particular, if you haven't been very careful when setting the low pass filters in your subs to match the natural low-frequency fall-off of your main speakers, you might have gotten used to the "bloated" bass caused by the interactions between their overlapping frequencies. Often people who've gotten used to inaccurate, boomy bass tend to feel that Audyssey's results are "anemic".
All of my speakers ( Sonus Faber "Electa Amator II" front mains , Sonus Faber " Solo" center and Jamo D8 concert surrounds and Jamo E6 surround backs) are full range .
The calibration level that I use is a sound meter from RadioShack and I do it at 70 DB, "C" weighting and "Slow" response and not at 80 DB.
Audyssey's calibration is done at 75dB. It doesn't matter what level is used for a calibration, so long as it's consistent. 75dB is quiet enough that it doesn't bother most people, and its individual calibration pulses are brief.
The two SF "Gravis" sub`s filter pass are set at 47thz , so , as they go down to 24hz , they take care of the real low bass over the speakers at that higher point very fluidly and with much better impact , of course , although I get bass from the mains too but these subwoofers are very musical and they modulate the lower bass notes incredibly .
I really don`t know how I am going to interact with setting the speakers to "small " and the subs to 80 which seems silly to me ... I think that I tend to mix my "audiophile" point of view with the correct calibration for movies .
There are several reasons for choosing a crossover frequency of 80 Hz, which you might want to consider. Some are related directly to sound quality, others more to electronic capabilities.
1. Room modes: Low frequencies interact with your room's dimensions, resulting in peaks and nulls in sound levels at various locations and frequencies, potentially up to about 200 Hz depending on the size of the room. This is quite unlike how higher frequencies interact with the room's surfaces. You have to place subwoofers so they produce the flattest response at your main listening position. The optimal locations for subwoofers usually are not the same as the optimal locations for your main speakers.
2. Speaker capability: Distortion increases as you push speakers to the limits of their frequency performance. By offloading the lowest frequencies from the mains and surrounds to subwoofers which are better designed to handle them, you're reducing that distortion.
3. Amplifier capability: Distortion increases as you increase an amplifier's output toward its maximum. Most of an amplifier's power is needed to drive woofers at low frequencies. By offloading the lowest frequencies from the amps used for the mains and surrounds to the amps in the subwoofers, you're reducing that distortion, too, as well as making more headroom available.
I guess I am in for a lot of experimentation .
Yup! Some people consider this an enjoyable part of the audio hobby. Not all do. (I'm actually more toward the latter end of the spectrum.)
I use the front main speakers and the subs with my other stereo hi-end equipment too , so I alternate them (I have developed a system of 2 sets of cables for that) , but the Denon 7200W will be used just for movies and internet music , Pandora , etc . The trick will be to find the balance between the setting of the speakers /subs with the different movie sound types and Pandora`s music ... ah, well !!!
D+M AVRs and pre/pros support using separate connections for separate sets of A and B main speakers. Using that feature does reduce the options available for the main surround-sound configuration, though.
And, of course, if you decide that you don't like how Audyssey works in your room, you can easily disable it.
I hope these comments help a little.
