The MCS-2A keypads work exceptionally well in controlling the MDS-6A music distribution system. Instead of using any of the MCS-1A keypads, I opted for the more expensive MCS-2A keypads because they offer much greater control over the stereo equipment that's playing. As it's only the right keypad that's "programmable" and because the right keypad is only provided on the MCS-2A, the MCS-2A does take a bit more work to set up with the IR codes of your stereo equipment's remotes. But, setting up the IR codes is super-easy and I can't imagine it wouldn't work with ANY remote--- you just point your remote at a keypad, hit a button on the remote, tell the MCS-2a to "learn" the signal, and the corresponding keypad button. Once you've trained one keypad, you can clone all of the others through a brilliantly simple process that ChannelPlus has created.
Note: Despite the wording of the installation instructions, I've had perfectly good success with my MCS-2A and MDS-6A just by using ordinary ethernet connections (straight-through EIA/TIA 568A connections). Reviewing the wiring instructions, it's clear that the connections are intended as straight through connections, so it's unnecessary to vary from industry standards. If you're having a contractor put in the wiring, just ask them to make sure to put a standard ethernet connections at both ends--- preferably male connector in the double-gang outlet box in each zone and a female connector for each zone in the wall plate behind your MDS-6A.
