Used a couple with an Integra 2 zone AV receiver. One controlled main zone and the other zone 2. Outstanding.
Using others to control the Integra MZA4.7 4 Zone DA piece and again, outstanding. I think that keypad is a real keeper. Bright and it does a great job.
There is no truth anymore. Only assertions. The internet world has no interest in truth, only vindication for preconceived assumptions.
