As a general rule input jacks (on equipment) are female (requiring a male cable connector) and output jacks (on equipment) are male (requiring a female cable connector). So a regular XLR cable M/F is what you need.I just picked up a good used pair of JBL Eon 15" G2 powered speakers. Trying to use them for the first time at band practice it seems that I need a female-to-female XLR cable for input from the mixer. Does that seem right to you?
