BFC - It's a beast

[obbm]

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?

Nice one Dave - light weight gear is for losers ;0)

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

Yes I had [i]something [/i]along those lines confirmed to me by the guys at Trace when I took my 122H up for them to look at years back
