So I got a call over the weekend about a 500' fiber snake with power and 4 channel Clear Com line that was malfunctioning. Asked about the termination boxes - if they were wired right and or if there might be an isolation problem within them. My answer nope, not the boxes plugged into, yet when they bypassed the snake system the new style Clear Com dual channel combining into one line system worked fine - had to be somewhere in the snake or boxes. First the patch boxes FOH and Dimmer end have air between and four channels splitting off from the cord and going to their outputs - not from the boxes - too much air gaps and space between the four lines. Other note was that our more normal as it were old style two channel Clear Com worked with the 500' snake, just something about the channel combining system working with a digital grade snake (about the best you can get), at 500' in how they did it. Once figured out part one of what the trouble was, part two instantly solved it on a tour that's been mentioned recently on the forum. Just a question of patching something in another place it turned out - this after the symtoms and trouble was figured out in why. 1) What was the cause of this bleed between channels especially at the front of house? 2) What given new Clear Com dual channel combining into one was the solution?
