I just got the amp and surround speakers this week and got around to setting it up tonight

I have a DVD player, Motorola DVR and PS/2 hooked up. I already had a Buffalo IR repeating system in place that worked fine with the old amp. For some reason, I can't get the IR commands from the Onkyo remote to work when going through the repeating system. It works fine when I point it directly at the receiver.

Here's the testing I've done so far.

I can use the Comcast remote that came with the DVR and it works fine controlling the DVR and DVD player through the IR repeater. I can take the flasher for the receiver, hold it close to the DVR and it passes the signal through no problem.

When I use the Onkyo remote, the signal LED on the flasher lights up, so it's definitely receiving the signal.

I've tried holding the Onkyo remote 1' from the IR receiver, no change. Again, I can point the remote in the general direction of the sensor on the receiver and it works great, even if I'm 10' away.

The only thing I can come up with is the repeating system is somehow corrupting the signal from the Onkyo remote, but that just seems odd since other remotes control other components through it just fine, including my prior receiver.

BEIRE1 Buffalo Electronics Infrared Flasher/Emitter
BEIR250WI Buffalo Electronics J-Box Style IR Repeater/Receiver

Receiver and connecting block are connected by 30' of CAT3 cable

Has anyone run into a problem like this before?

I believe Onkyo uses the standard IR frequency, so ... I have seen components get overloaded by the signal from the emitter when the emitter is attached to the device. Try putting the emitter some distance from the receiver and see if that helps. If it does then you need to attenuate the IR from the emitter. But try that first, then determine if you need to attenuate it and post back.

Thank you for the response Aymanme. When I was first testing it I did move the flasher up to 8" away and slowly moved it to touching while running signals through it.

I ended up resolving the issue. I took the flasher on my DVR and put it by receiver and it worked. I did a bunch of swapping around and found out that all 3 of my flashers worked fine on the DVD and DVR, but only one worked on the amp. I guess it needs a pretty strong signal for the IR sensor on the receiver to pickup.

seems like that would have to be some pretty high tolerances with emitters to have them be so different that some work with devices and some don't. If your problems come back you may just need to shift the emitters so not directly in front of the IR window or try different emmitters.
