Can I plug a 3.5 into the emitter port on the wall-plate and into the receiver port for the Xantech? I didn't want to try it in case it might blow it up. I know the Xantech runs on a 12v but 3.5v and 5v are also common for IR. I can't seem to find the output specs for the wall-plate. Possible to hard-wire to the Xantech and just not the power line?
The Monoprice plates you linked to don't have their own IR receiver; they just act as a pass through. So if you plug a 12v compatible IR receiver on the receiving end that is compatible with your Xantech block, it will work. Also, the receiver that comes with it won't work in your setup. I'm saying that from personal experience .
