Question Yamaha RX-A3050 YPAO and 2 subs


Distinguished Member
I have setup my system to 7.2.4 manually however I now want to run YPAO so my question is about the 2 subwoofers.

I have a single output cable from the Amp to a Y splitter feeding into Monitor Audio RSW12 line in connections then I am using the line out from the RSW12 to the low level inputs of a BK Monolith.

I have set the amp subwoofer settings to Monaural x2 is this correct ?

Should I be having both subs on during the ypao calibration or should I run with one of them off first then run again with the other one off and then manually adjust the subs so my level is somewhere between the 2 measurements ?

Also should I set one at 0 phase and the other at 180 on the subs themselves ?

Any help appreciated

Use the two sub pre outs and each subwoofer will be EQ'd and levelled independently by the YPAO calibration. Continue using the connections as you have them and the calibration will treat both sub's as though they are a single unit and will not see them as being 2 subs.

The phase on both subs should be set to 0°. The AV receiver sorts phase and synchronisation out via its distance settings.
