The Digital IR 8-Channel Receiver from Listen Technologies receives the digital IR signal and offers the user channel and volume control. It is worn in a shirt-pocket or around the neck with a lanyard and uses an external headphone with a standard 3.5 mm stereo jack. The capacity is 8 mono standard quality channels, 4 mono perfect quality channels, 4 stereo standard quality channels, 2 stereo perfect quality channels, or a mixture of the above. The receiver will only display the channels and languages that are programmed on the transmitter, as well as indicate the volume level, battery level, and reception status on the LCD. The receiver is automatically turned off when the headphone is removed or the transmitter stops transmitting, in order to save battery life. The battery life is 52 hours with a NiMH rechargeable battery pack or 70 hours with two alkaline AA batteries.
