The OMNITRONIC MCS-1250 MK2 IR Emitter enables audio and video equipment in other rooms to be operated with an existing remote control. The MCS-1250 MK2 wall controller receives the remote-control signal, while the emitter transmits it to an audio and video component with an infrared sensor. It supports standard equipment such as HDD recorders, set-top boxes, satellite decoders and stereos. Connection is via a 3.5 mm jack plug.
