    Phase Linear Question

    Are the preamp outs and poweramp inputs balanced or unbalanced? I have a PL3000 preamp and a pair of PL400 poweramps. I want to add a crossover between them to drive one PL400 for the JBLs (psudo L-100s) and the other PL400 to drive the subs.

    I'm trying to decide upon a crossover, but need to determine whether or not I need unbalanced input/output.

    What type of input/output jacks do they have? RCA is definitely unbalanced, 1/4" could be either, if set up with TRS, (Tip, Ring, Sleeve), and XLR can also be either balanced or unbalanced, depending on internal wiring. A little research on the web would surely turn up more info.
