obbm Posted December 4, 2007 Share Posted December 4, 2007 Scored this for a very modest sum on Sunday to use when I have to provide an amp for others to use, especially local outdoor festivals. It's a bit weighty but does have very chunky wheels and handles. It has three speaker circuits, 15-inch, left 2x10 and right 2x10, all of which are 4-ohms and was designed to run from the Trace AH1000 which had the option of three power amps. I want to run it from either the old Ashdown ABM500EVO or the even older Sound City 200. The cheapest, and lightest, option is to :- Swap the 15-inch for an 8-ohms one I have in another Trace cab Rewire the two 2x10s in series to give 8-ohms Then parallel the 15 and the 10s to get a total of 4-ohms. Another option is to use a separate power amp to drive the 2x10 channels. That would give me the option of adding a crossover at a later date to give true bi-amping or even triamping but would mean having to cart more gear around. The first stage is to swap the 4 pole Speakon for an eight pole and bring all the connections out to the rear panel. Anyone ever used one or modified one?

gypsymoth Posted December 5, 2007 Share Posted December 5, 2007 haven't got a cab like that, but have an SC200, 100, & 120. and cabs woth 10's, 12's & 15's. so my vote is two 8 ohm jacks, so you can run with one head with either or both speaker sets - or bi-amp it Quote Link to comment Share on other sites More sharing options...
