Hi there,\n\nI'm wondering if anyone has any info on what the Yamaha YPAO light actually means? And possibly further information on what I should set (if still applicable) \n\nSo more recently I had setup my AVR manually as I couldn't find the mic. Naturally the YPAO light is off when doing this. \n\nI found the mic so I ran the entire auto setup again. (see attached screenshot for checks) \n\nSo now the YPAO light is on. (see attached picture) \n\nFrom some little info's I've read they seem to suggest that when YPAO is on it will automatically adjust sound for optimal listening. \n\nWhat I am not clear about is the actual purpose of the light being on. Is this actually doing something like adjusting the audio output depending on the source? Or is the only purpose to indicate that the setup was done with the mic? \n\nIf I adjust ANYTHING, the light will turn off. I'm not sure if I should really care or not. \n\nNow originally I had done some reading on what kind of settings I should use such as those found here: https:\/\/www.audioholics.com\/home-theater-calibration\/a-v-receiver-setup-crossover-distance-level-eq\n\nSeems to possibly conflict with what YPAO did. \n\nMy speakers are all set to large. Which is mostly what I had before also with the exception my center was small.\nBut more importantly I am interested in the crossover setting. My AVR has one crossover for all speakers and YPAO set it to 40Hz. (see attached picture) which previously I had set to 90Hz. \nI'm not really sure which is better? \nMy front and surrounds should all be pretty capable to get pretty low but the center I believe is rated for 80Hz. \n\nSo if I adjust this, YPAO light goes off and I'm not 100% clear if thats still good and\/or if I should trust the YPAO crossover settings? \n\nThoughts? Comments?
