I am working on an elaborate multi-screen system right now that I'm having a little problem with. I am generating some of my commands with a macromizer and others with a Xantech URC-2 remote. Several commands are less than reliable and I suspect that I'm asking too much of the macromizer as far as the number of emitters it can drive simultaneously. I am trying to drive 4 emitters at a time with the output of the mac, but I'm using an RT-8 router in between the mac and the 789's. Xantech doesn't mention in their literature the output current of the mac, or the loss caused by the RT-8. Is the RT-8 passive or does it re-amplify? If it is passive, I would think that it would have some loss. My questions: Will the Macromizer drive 4 or 5 emitters at once without a 792 or 791-44 amplifier? How about the RT-8-- will it pass an amplified signal, such as the output of a 791 with 10X jumpers? Does the RT-8 have current-limiting resistors built-in for the IR outputs? Is the URC-2 flakey or is it me?

Looking for an IR genius. Where's Fred Harding when you need him?

Just call Xantech, they know their own stuff quite well.

You're very kind.

Output of the Mac 1 goes to the 791-44 to the RT-8 to the devices to be controlled.

The RT8 is buffered. That is the only way they could get all eight outputs on at a time, which is a switching choice.

Thanks for yor help guys.

With the RT-8 being buffered, will there be enough current left from the 791 to power the emitters through a 789? What size resistors are used to buffer the outputs of the RT-8? I guess I should take it apart and look.
