I followed Almarg's advice in taking 18' balanced lines through unbalanced equalizers just before the amps using Jensen ISO MAX transformers that terminate at the amps with RCA to XLR cables. That termination turns out to be important.
In my setup using XLR to RCA adapters resulted in audible sizzle.
