Ho a calibrare tutto spostando alcuni pannelli. Il risultato è identico! Sempre effetto radiolina.
Ho trovato sulla baia il microfono acm1hb del denon, il quale dovrebbe essere identico a quello del mio onkyo. Proverei ad accattarlo e provare.
Quel Mic (ACM-1HB) funziona con tutti gli Onkyo prodotti dal 2010 in poi, allo stesso modo del modello DM-A409 e del modello ACM-1H, invece i modelli fino al 2009 di Onkyo e fino al 2007 di Denon e Marantz non sono compatibili.
Dalle FAQ di AVSforum:
The ACM1H mic is interchangeable with the DM-A409 mic used with Denon AVR-XX09/X89 through AVR-XX12 models. Older Denon models use the following mic types, neither of which is compatible with each other or the newer DM-A409/ACM1H mics:
XX06: DM-S205 (hockey puck style)
XX08/X88: DM-A405 (tower style)
4308/5308/AVP: DM-A505Z
5308/AVP (w/3D upgrade): DM-A409
With the introduction of the new Denon AVR-XX13 models, Denon is now including the new "ACM1HB" black mic which Audyssey has confirmed is interchangeable with the DM-A409 (Denon) and ACM1H (Onkyo, Marantz) mics.
(Thanks to AVS Member jdsmoothie for Denon mic information)
UPDATE June 2012: Onkyo, Marantz and Denon units now all use the same ACM1HB mic.
If you damage or lose your mic, they are available from your unit manufacturer for around $US25. Be very careful about buying from other sources such as auction sites as there have been counterfeit mics (especially from non-USA eBay resellers) seen there (as verified by Audyssey) and these will quite probably not be properly calibrated by your unit's calibration file.
Long story short - take care of your mic and preferably use the one that came with your unit.
