You asked for advice, opinions then argue against them.
If the 20k is that important to you leave it in, IMO it doesn't do anything useful, but it won't harm anything.
I repeat my advice to add 475 ohm build out resistors to prevent one input from loading down the other excessively.

I didn't argue anything. I apologize if it seemed that way. I merely stated that I had read from other sources (that seemed credible and pronounced with conviction) that there was a reason given for the various components. I would suppose that you would then debate your reasoning for the uselessness of the 20k resistor. 1 - are you opposed to the value? or 2 - are you opposed to the presence of any resistor linking the + & -?
Without further info I am left to decide between Rane engineers' recommendations and Peavey Engineers' recommendation to pretty radically change the circuit. Now add Ivan (who is also trusted and knowledgeable), introducing ground lift recommendations.
Finally, does your recommendation for adding series resistors on each output side of the "Y" also apply to a single input to "Y"ed output. (mono mixer output split to 2 amps? Is so, why so, when many here have stated that output splitters are perfectly fine (limitations of course).
Thanks, as always.
