There are three files provided. One is the .mxf file with two versions of devices for the Anthem MRX series of AVRs. V1 is called M700A and v2 is M700B. M700B is the full layout of the main AMRX700 remote and includes several Zone 2 controls. M700A is a slightly scaled back version. All codes were learned into the remote and tested. The .mxf file has both M700A and M700B devices set to RF on Line 2. You may want to reset these to ALL if you use this file as your basis for programming the remote.
Anthem MRX Series Discrete IR Library for models MRX-300 MRX-500 and MRX-700. These were captured from the original remote and verified clean with no repeating or sloppy captures. This controls both Main Zone and Zone 2.
