I’m currently using 2 Pronto TSU 3500s & 2 RFX 6500s set to the same channel & 2 different IDs to control my AV system. One remote is in the living room & the other in the master bedroom. All AV components are in the living room. My home theater control center is a dual zone McIntosh MX-150. One ID controls Zone A (Living Room) & the other Zone B (Bedroom). The RFX 6500s are plugged directly into the MX-150 with no IR blasters. All other components are controlled with IR blasters. We just got a new TIVO that only uses its own RF remote control or a smart phone over wifi for control. I hate having to use a stupid remote after having the sophistication of the Pronto remotes for so many years. Any suggestions would be appreciated. We really like having complex macros run from 1 button push.
