I have had a problem with one of my rigs for the last two gigs. My set up is an Ashdown ABM900 amp, (two channel), XWire wireless (line runs from unit to passive imput), Euphonic Audio XL208 and Bag End S15XD (coaxial) cabs. Basses are both active - Musicman Sterling and Pedulla Rapture J2000. The problem is this: I will start the night off and all is well, great sound, plenty of punch....suddenly the bag end is gone, no sound. I am getting a reading on my xwire and on my amp to show that the signal is ok. The EA is fine. I tried changing speaker cables... the connection on the Ashdown appears not to be as tight as it should be. Initially solved the problem, then it came back. What is also interesting, is that it happens more when I am playing the Musicman. I normally run active basses through the passive imput, but is this causing some type of problem where I am using the XWire? Any thoughts would be greatly appreciated.
