Nexo NX242 Manuel D'utilisation page 31

If the MAIN SYSTEM phase reading appears to be superior to the SUB phase reading, then MAIN
SYSTEM will have to be delayed with a value close to the one given by the geometrical alignment.
If SUB appears to be in advance to MAIN SYSTEM, then SUB will have to be delayed with a value close
to the one given by the geometrical alignment.
Phase alignment can be considered as correct when phase is coincident over the entire overlapping
range (typically an 1 octave from 60 Hz to 120 Hz), and when the overall response is always superior to
SUB's and MAIN SYSTEM's individual response.
