NLB breakout box
This little nifty box is what we use to simplify our
speaker cable runs.  This box can be used for
everything from our large d&b line array systems
down to simply running speaker cable lines for the
front of a stage.  In short this gives us four
channels of amplification on one cable to be
broken out in whatever way we need.  Very handy
thing-a-ma-bob indeed.
