RX-V473 has the lowest version which doesnt do much of anything. Starting from 600 serie YPAO R.S.C is step up and has those Flat, Natural, Front curves which are missing from the lowest version.
The Difference between YPAO and YPAO R.S.C
Basic YPAO will do the following:
- Measure and set speaker delays (called – inaccurately – distance)
- Measure and set speaker levels / volume
- Measure the frequency response of your speakers and use a parametric equaliser (PEQ) to flatten the frequency response of the speakers/room in the frequency domain only (what it is doing really is match the timbre of the speakers to each other)
YPAO R.S.C (R.S.C. stands for Reflected Sound Control) is more advanced. It actually has TWO sets of filters:
- It will measure the impulse response of the main speakers (not the subwoofer even if the model has sub EQ) AND will create filters that will modulate BOTH the phase and the frequency of the response. This is to allow for removing the first reflection of the speakers in the room and it allows YPAO to tackle both the dips and the peaks in the frequency response. YPAO basic will only be able to tackle the peaks effectively and do a hit or miss with the dips. This is true of any type of parametric EQ. These filters are not actually displayed on the screen and are not editable.
- The second set of filters are only in the frequency-domain with a minimum phase: these are the PEQ filters that are used in the YPAO basic equalisation. But here, more broad filters can be used since the main / most difficult issues in frequency response have been corrected.
I will show you how to tweak YPAO R.S.C. manually.
