Hi all!\n\nI did some research but couldn’t find the answer, hopefully somebody experienced in Yamaha Parametric room Acoustic Optimizer (YPAO) can help. I own Yamaha RX-V781 AV Receiver. I changed all my speakers and need to optimize the settings again. Will the measurement results be affected by ‘YPAO Volume’ [and] ‘Adaptive DRC’ left from previous optimization and set to ON? In other words, are ‘YPAO Volume’ [and] ‘Adaptive DRC’ active and affect YPAO while it’s running calibration? Should I disable (set to OFF) ‘YPAO Volume’ [and] ‘Adaptive DRC’ prior to running YPAO calibration for new speakers and every time I re-run YPAO calibration (change room\/speakers or reposition speakers)?\n\nThank you in advance!
