I am using mx800 with xantech pa 1235 via rf controller in different room. I cut the head off an emitter and ran from rf receiver to xantech connecting block and from connecting block to pa 1235 common input. All zones work perfectly except 1 and four. Tried re learning volume up down and on off back into mx800 and resetting pa1235 zone freqs. Help

I have heard somewhere that you can use a Xantech Amplified connecting block when using the non-buffered outputs on the MRF200/250. Also, does teh IR work, or is it a problme with RF, or Learning. Make sure you have the have the setting on the RC68 programmer to the correct code group, and are using the correct codes. Make sure the IR works before you start with the RF stuff.
