Hey all, I have a DA4ES. It evidently has the capability (as does the DA5ES, if I remember right) to extend the IR capability through connections on the back panel for exterior receivers and emitters. Of course the manuals say just about nothing on the subject. Does anyone have any more information on them? What equipment will connect back there, does it work, how many emitters can you use, etc.? Such a great piece of electronics, such putrid documentation. Don't even get me started on the remote. Take care.
