I was getting short intertmittent burst of pink noise from my Meridian 568 and could not figure out what was causing it. So I recaliberated the processor,to no avail, the pink noise still continued. I then checked my connectors and found a colony of ants inside the shell of the RCA pin of a Monster Cable. I replaced that digital connector and I still get that intermittent pink noise when changing sources. The 568 will be going back to Meridian soon. But, what would cause ants to colonize a Monster Cable?
