I have to agree with echoslob. Most of my zone 2 has been with Marantz. I use a Xantech universal translator into the zone 2 control input and standard remote codes work just fine. If I need Z2 control from the same room as the receiver with a learning remote I use a xantech RT-8 router. I haven't installed the SR9200 or 8200 but they have some discrete Z2 commands and shouldn't need the router. Xantech has an IR controlled speaker switcher that can be used as a 2 way router but I havn't tried it yet. I haven't done a Yamaha in a few years but they came with a seperate Zone 2 remote on some models
