I've just installed on my HT an Onkyo PR-SC5507 processor and I've tried to perform the Audyssey calibration but unsuccessfully, because Audyssey doesn't detect my subwoofer.
When I run the calibration at the first mic position, when is time for the subwoofer output I clearly hear the sweep signal running twice, the second time a little louder. But when I move to next mic position the subwoofer test is skipped and, at calibration end, the screen show me that Subwoofer is NO and consequently the front main channels are set to full range. Some info: the Onkyo is loaded with the lastest firmware, the HT is in a dedicated space, the room is very quiet and, most important, the subwoofer is a passive design with an 18" woofer (18 Sound) powered by a 1kW amplifier by Powersoft (so there are not phase controls or LP filters).
What is wrong?
Thank you for your help
