Thank you all, especially Derek, who has the honour of being the first respondent to my first Mayhem Forum Pos!
I did wonder if the P110 was actually Action Electronics P100 "Noisy Thing"
Currently this falls over purely because it is Windows based and all my sounds etc are on a Mac! Secondly it would be good to hear of anyone else's experiences with this piece of kit, ease of use, control of it, does it multi function, i.e. supply the "background Auxiliaries sounds ( gennie's, fans, pumps compressors etc) and then give main engine and or thruster sounds simultaneously as in the real world, or what.
As to the advice on speaker, mounting of etc, fully understood, have awful memories of early sound system at home, all due to poor speakers!!
I know I am new at this sound thing, but cannot help wondering why I keep hearing model boats that have engines that would be air start, by air admission direct to its cylinders sounding like a Big Rig with an Electric Starter Motor!
Am thinking that this may be a lost cause right now, due to the end result not matching up due to amp and speaker limitations in a model boat. No sound is better than a bag of spanners rattling away!
Any more thoughts from you knowledgable ones, thanks
