The XL2 is a very useful tool to adjust (not so good sounding) PA systems. I tune both sides of my system independently, so I wonder if there is a way to compare the results of left and right using the XL2 easily.
Thanks in advance, best regards

A couple ways to compare left and right using your XL2
Use SLMeter (all XL2s)
Adjust you system so you are only playing pink noise from either left or right (e.g. fader or WAV/MP3 file with only left or right).
Make a Leq measurement on RTA screen (1)
Select the Result Symbols/Capture icon (2)
Capture eq (3)
To display that first measure along with a second measurement, select either the line or bar parameter (4)
Chose Capt (5)
Now you have left and right on the same display.

Hi...i want to know. Is there any reason for having dedicated Left and Right speakers?I
can understand it with headphones for fitting in your ears or over your
head, and maybe for a track that has a lot of noticable panning you
could say you were listening to a track back to front. But for say, just
a pair of computer speakers, does it really matter what side they go
on?

The left and right speakers are actually identical. The created stereo effect improves the sound performance. In cinemas you may see five or more channels for an even better sound experience.

I also do not see a
reason for having a dedicated left and right speaker, but there are situations
where the left and the right speaker (or speaker system) do not sound the same.
This could have various reasons, like wrong crossover or amp gain settings,
defective speakers, unsymmetrical speaker placement, ....

The second method requires the Spectral Limits Option for XL2.
It will allow you to show the relative difference between left and right with up to 1/12-octave resolution.
- Again, make a measurement a Leq measurement of only the left or right channel (see previous post)
- Select the Result Symbols / Capture area (1)
- Capture EQ (2) to location C1 (3)
More details in 1/12 Octave + Tolerance section of the https://www.nti-audio.com/Portals/0/data/en/XL2-Manual.pdfChange the top line display to "---" and select the bar display (4) to EQ (5) Difference (6)
You may need to adjust the scale by clicking on the Y-Scale setting (7)
