I need help from anybody who has a Yamaha receiver with YPAO function. Please let me know if you can hear test tones from the speakers when you are doing the AUTO setup for EQUALIZING. I cannot hear any test tones with my receiver when it is performing the EQUALIZING setup. I would like to know if it is normal or my receiver has a problem. I can hear test tones when it is performing speaker SIZE/DISTANCE, LEVEL and other auto setups. I can also hear test tones when doing Manual setup for the center speaker. The user's manual says YPAO equalizing can automatically adjust the frequency characteristics for all the speakers. But I do not understand how the receiver can auto-setup and adjust each speaker's frequency characteristics without audible test tones.
