ok cheers, I'll try what has been suggested, thanks for all the help.
I found the message for the volume hack..
http://empeg.comms.net/php/showthreaded.php?Cat=&Board=hackers_prog&Number=22782&page=&view=&sb=&o=
So setting it to 90 gives 100% volume (4V), so Idealy I should set it to below 50..

btw, thats the only lineout converters I can find, I guess there is no aftermarket product to do that sort of thing.

Cheers,
Jai
