2008-01-31 1:17 pm
i have just built 4 gainclones for a couple of systems and they sound great i used the pre made pcb s from chip amp . com and the lm3875 chips all fine what i want to do next is bridge 4 or g of those to gether for each channel of a power amp i have seen some people have done this before but i cant find any info on the builds anyone have any ideas i see one of them uses a ballanced line driver on the input is this overkill or nessacary when bridging chip amps
any info would be good
many thanks:)
