DENON RC-1121 (307010045008D) original remote control

Remote control that incorporates 4 different controls. On the top part of the remote control, you can see the options M (Main), Z2 (Zone 2), Z3 (Zone 3), and Z4 (Zone 4). The main function is the main control and is used in most occasions, while the Z2, Z3, and Z4 options are used to control three other devices identical to the main one, all located in the same room as the main one. By defining the zones, we ensure that the remote control can operate all four devices without the signals from the remote control mixing with each other and preventing all four devices from reacting to a single instruction from the remote control when a key is pressed.
