PS audio C250

i have used PCA-2 and C250 x 2pcs for a very long time

One C250 for left and Once C250 for right

But both C250 runs at stereo mode for High and Low

i need XLR 4 pcs,

Suddenly, i think is it possible to have mono input and stereo output to save 2pcs XLR.

i don’t find any info about the jumper. Thanks.
