A complete setup with three components combining all functionality from the T1 and T1+ remotes. Better than the stock MX-500! 1) Main Zone discrete codes for input, power volume, and toggle commands for screen on/off, surround mode, input type, Hi-EQ, Midnight mode, etc. 2) Full tuner controls. 3) Second Zone discrete commands for power, source and volume (not compatible with non-plus model).
