For the office system there are 2 control systems. Around the house they have URCs so the MRF300 is wired to the components. The T4 in the theater is talking to a RP1. I took one out put of the RP 1 included block and direct wired it into the MRF300. No issues with not enough power. I did not turn up the block. How ever it was in the box is he level I left it on. Actually, the flashers on that system are talk backs and I would say the level looks too high as they light up like Christmas.
