We have a Laney 8300 PA amp that has twice cut out during a gig. This amp is rated for use down to 4 ohms. The first time it cut out we subsequently found one of the speakers was open circuit. We also had the amp looked at, a new thermal fan unit was put in so we thought that would be OK. However, having replaced the dodgy speaker it has tripped out again. Something tells me it's a speaker problem rather than the amp itself. Interestingly, when it cuts out it is the thermal warning light that comes on, not the load protection light!!
I have now been running it at home using a guitar and a mic with amp connected to a single 8 ohms speaker and it has been 100% fine, no cutting out at all. Questions are:
1. If the two PA speakers were mismatched, ie one was 8 ohms and one was 5.5 ohms, could that cause it to cut out??
2. Before buying a new set of speakers, is there any way of testing ie placing a "dummy" load on the amp to see if it cuts out again.
3. Bearing in mind that we play small places so don't push the amp to excessive volumes, can an amp make speakers go ope or short circuit??
If anybody can offer any advice I'd really appreciate it.
