Hey Guys,

I'm having a problem controlling one unit in my system. It is a Scientific Atlanta 8000HD DVR. I can control all other components with IR emiters in my cabinet coming through my Xantech 780 from my Russound PR-4Z Preamp. Does anyone know why the SA8000HD may not be controllable with an IR emitter? The emitter works, I have tried it on other devices. The signal from the remote works. It works directly with the SA8000HD. I just can't get it to control with the doors on the closet closed. Any suggestions?

Thanks,
Mark

Nothing is wrong with your Xantech system. I had a similar problem with a Russound CA4.4 and a HD Cable Box few months ago but I can't remember right now how I solvednthe problem. If I remember I will posted here but I remember I read a post related to this issue a couple of month ago either here or at integrationpro site.

Thanks flcusat. I will search for posts, hopefully you will remember what you did. I appreciate the input.

Thanks,
Mark

Hey guys, I found this on Xantech's web site, could this be my problem?

"Issue:

Using a CFL-Friendly IR Receiver (291-80, 480-80, or 780-80) and trying to control a unit with a carrier frequency greater then 40kHz (I.e. RCA DSS, Scientific Atlanta, Jerald, and General Instruments Cable or DSS Set Top Boxes


Solution:

If you are using the 291-80 or 780-80 CFL Friendly receiver, locate the Carrier Frequency Adjustment on the unit and using a small blade screwdriver, (3/32" blade width max.) rotate the adjustment for best performance of all the units in the system. Note: The 480-80 version does not have this feature; you will either need to change the unit to a 291-80, 780-80 or the 490-90. The 490-90 is a wide band unit and will not require any frequency adjustment."

I am using the Russound PR-4Z with a Xantech 790 connecting block for my emitters. I don't think there is anyway of adjusting the frequency on either one of these. Am I screwed and have to buy something else?

Thanks,

Russound has an adapter that works with the CA4.4/6.4 systems that allows for IR control of SA cable boxes. Not sure if you can use it in your particular application, but I'd recommend giving Russound tech a call.

Thanks TSS,

I was just coming back here to say that Russound has a modulator that plugs in between the ir output and the ir emitter that re-modulates up to 58kHz for HD boxes, sat boxes, etc anything that uses higher freq ir. Thanks for your help also. I will call my russound guy tomorrow and see if I can get one.

Flcusat, is that what you had to do?

Thanks,
Mark

I can't remember exactly what I did but it could be that the IR frecuency of the cable box is different. If that is the case you could use an IR receiver like the 780-80 or 291-80 which have an IR carrier frecuency adjustment. But I'm sure by tomorrow you will have more answer from people at this forum.

Try using non-blink IR's (if you're using blink versions).

I had a similar problem with a Russound CA6.4IL. I fixed the problem by linking the Russound to the Xantech connecting block by inserting the cable into the the number one IR emitter port instead of the link out port. I am calling the #1 emitter port the one that is next to the link out port. Don't ask me how or why but it fixed my problem once and for all. Good luck.

I just talked to my Russound guy and he said I was right. I need a remodulator and power supply for it. He is sending one to me today. He said he runs into it all the time with the SA boxes that Time Warner distributes.
