Dummy cable in right output solves or creates a problem?

[Indianrock2020]

Some patch makers suggested a dummy cable in the right output to solve a "problem" with "left sum to mono."    But today somebody mentioned that once  a cable is plugged into the right output, the Helix won't sum left to mono and both outputs would get half of a stereo patch signal.   With the dummy cable, your PA might be getting half stereo ( missing info required for a reasonable FOH sound)

Deja vu...

 

 

No, a dummy cable plugged into the right side will not correct any mono summing.  You will be getting only the left side. 

 

There is a bug in the Helix, all info is in the thread above.  Instead of a dummy cable, simply get a splitter cable.

Important notes for users running mono:

• Use a dummy XLR on either the left or right output so your wet effects don’t sum to mono (summing to mono modulating wet effects sounds suboptimal)."

Helix has weird behavior with some effects, so maybe...

 

For example the doubler effect when running in mono does weird phase cancellation... so ... sure. 

 

Most likely the person didn't build the patch correctly that's why there's this very bizarre instruction.

If there is a consensus it seems to be that the Helix isn't going to know that the cable is a dummy cable so probably better off not putting that in there.... maybe you want to avoid things like ping Pong delays if you're going left mono out.... what I really want to find out is if I can take two mixer channels and send both left and right from the helix even though the mono PA is not going to treat those two channels any differently.
