All you have to do is remove the DA jumper between H1 and H2 on the regulator board (19C320916G1) when there is no speaker or speaker load connected to the Auxiliary Receiver audio output.

It might be easier to take a separate IFAS board and empty it, then take it to the site and swap... definitely reduce power consumption and weight :-) Doug At 11:50 AM 12/11/2007, you wrote: >Doug & Jim, > >Thanks for the replies.
