The JBL crossovers have 2, 1/4" TRS input jacks (2 for bi-amp, 1 for non-bi-amp) and one additional other large jack (e.g. Jack #3) that looks like a BIG XLR input but it is NOT an XLR jack.
I think, I think, I think, Jack #3 on the JBL crossover has a sticker that tells how to wire the internal jack pins to achieve bi-amp or no bi-amp ?????
On the back of Crown XLS 802 power amps are two jacks that look like they match the "Jack #3" JBL crossover inputs.
Question: What is the professional name of these jacks/cables and can I run one of these cables between the Crown power amps and the crossovers in a non-bi-amp configuration?
