Is it 6 pin or 5 pin? It is probably a DIN connector. Two pins are left i/o, two pins are right i/o, one pin is ground, and if there is a sixth pin it is likely phantom power.

yeah the mic input is 6 pin. there is an output which is five (i found and adapter for this) and then there is a speaker output also which is just 2 thin rectangular holes, one smaller than the other. but it was the mic input thants the main problem. i think cb radio mics are 6 pin. dont know if that would work tho...

cheers

I'd buy a manual download and then you'd know for sure.
