I'm looking into building a simple 16ch passive summing box, and I'm wondering if anyone here uses one in their setups? I plan on using 2 DSub connectors, 8 channels each. 2 XLR outs, a la the Roll Systems Folcrom, but no left/right buttons...just predesignated. With that in mind, parts alone shouldn't be more than $75, which will include: -1u powdercoated chassis -2 Male XLR panel-mount jacks -2 Female Solder Cup D-Sub Connectors -32 1K Ohm metal-film resistors Compared to $750 or so on the Folcrom, I know it'll take labor, especially w/ the D-Sub's, but I think it'll be a fun one! Any of you built one of your own?
