Si, mi ricordo del problema del sub ma a questo punto se e' tutto spento evidentemente e' il 507.
Fai questa prova, scollegalo dalla corrente dopo averlo spento, riaccendilo, resettalo (sul mio devi tenere premuto sull'ampli [VCR/DVR] e premere [ON/STANDBY] sempre sull'ampli, compare la scritta "Clear" e l'ampli va in standby), spegnilo, scollegalo dalla corrente per almeno un minuto, ricollega, riaccendi e riprova.
Non credo tu possa risolvere cosi' ma una prova vale la pena di farla.

b)2. Why is Audyssey reporting 'Ambient Noise Too High'?
This error message usually occurs if Audyssey detects a level of background noise in your room which would preclude a correct calibration. When running the measurements, be sure to turn off anything which can contribute to the background noise. Prime suspects are:
HVAC units
Room or ceiling fans
Noisy refrigerators
Children smile.gif
Buzz from cable or sat TV box
Buzz from light dimmers
Aircraft overhead
Road noise from outside
If Audyssey detects on any of these it will try to create correction filters for them and this will clearly adversely affect your results. Remember, just because you can't hear the noise doesn't mean that Audyssey can't. If Audyssey detects the noise level is too high, it will raise the level of the chirps and try again. It will do this three times before giving up and displaying the error message. So long as the error message is not displayed, Audyssey will cope with the ambient noise level and deliver a good calibration.
If you get the error message and you have ensured that everything is turned off, you might want to try the calibration later at night when external noise is usually much lower. If you still get the error message despite that, then there is a chance that you have a fault. Often the mic may be faulty or have become damaged. Mics can be damaged by static electricity for example. If this is the case, you will need to obtain the correct replacement for your mic and then try again. If your unit has a factory reset procedure, it may be worth trying that before you blame the mic.
It is worth noting that you do not need to be paranoid about background noise levels. Chris Kyriakakis has stated (Ask Audyssey 14 July 2012) "If you are not getting a noise error then the data collected is perfectly fine." In other words, the calibration is not somehow 'improved' by having a very quiet background noise level. Just keep the noise levels as low as you can when calibrating.
Similarly, some people have worried about a sudden, loud transient noise affecting the quality of their calibration - such as a clap of thunder or their dog barking. This is what Chris Kyriakakis has to say on that subject (Ask Audyssey 14 July 2012): "The reason we take 10 chirps per speaker is to overcome the effects of transient noise. They will be averaged out if they only happened during one of the chirps."
e quella "ufficiale" di Chris di Audyssey:
Hi Walter, the two most common causes for this are: (1) buzz from the cable/sat box and (2) buzz from light dimmers. Please try disconnecting all sources from the Onkyo and turning off light dimmers. I believe that you have some sort of electrical noise that is causing this.
