Ack, thanks Mike, wasn't sure if it was even possible..wanted to build
a cheapy IR controlled speaker interface, i can always build what i
was going to - but without the IR. Was thinking with the IR idea that
a tap of the channel up button..when wired to either a pot connected
to the volume on the speakers itself, or a digital vol control would
raise the volume up one..a tap on the down button would lower it
one...possibly use the pause circuit on the board as a mute. Is there
anything short of building it myself that would accomplish what i want
to do and allow me to use my existing remote and my existing speakers?
It sounds great hooked up to my dish and such, but wanted the
versatility to control it remotely.
