In other news...

It was nice to put together the ragbag of bits that is by PA system for the first time in a year and find it all works as expected. Got an irritating and difficult to trace fault with a Tascam digital mixing desk. The desk keeps losing track of where one particular fader is. Tried replacing it, no different. Probably means there's some impedance measuring going wrong. Actually I have no idea how it works... only that sometimes it doesn't.
