			== Wiring ==

			The whole thing is now cabled with three-core xlr:


			Red: Hot/Send

			White: Cold/Return

			Shield: Power


			Within the boxes, there is a choc block connecting the incoming and outgoing xlr components with three small wires. These wires then connect to the corresponding xlr pins.

==Things to Note==
There is a nagging suspicion that the audio cable broken and coiled beside the SL folo may be the remains of the backstage end of one of the rings. One of the amplifiers has an undiagnosed fault and eats fuses. Also, we have a problem with people stealing beltpacks, which are <i>extremely</i> expensive. One disappeared in 2007 some time, and one during Fringe '08. It should be noted that it is possible to bypass the hardwired comms ring entirely, and daisy chain beltpacks together with the amplifier. This may often be the easiest option.
