I am part way through a speaker project. I have the cabinet built, but i also have built an amp. I need to know what terminals go where.
The amp is powered via 12v, but i wanted to power it with 230v mains supply. I have the transformer, so i need to know what inputs and outputs go where. Thanks

Thanks for posting, but you haven't helped me a single little bit.

The drawing at the bottom of page 5 in the data sheet for the amp shows you exactly where to connect the transformer. The transformer is actually a 24 VAC, center-tapped secondary. Connect the center tap of the transformer to ground and the other wires to the 12 V terminals. Center-tapping the 24 V transformer give you 2 - 12 VAC windings. This is what they mean when they say 2 X 12. Two 12 VAC sources.
The input to the transformer should be marked as AC or the little squiggle line ~.

Make sure you match the ground of the power supply with the ground of the amp, otherwise you could get a shock.
