目前的遥控彩电大多都具备AV输出插口。这里介绍的伴音转发器正是利用这个插口取得伴音信号、转发至88～108MHz调频波段,然后用袖珍调频接收机,插上耳机收听即不影响他人。因其具有自动通电、断电功能,所以与遥控彩电配合使用甚是方便。并且电源控制电路工作时耗电很小,不工作时不耗电。
Most of the current remote color TV with AV output jack. Introduced here is the use of audio transponder audio signal is made using this socket, forwarded to 88 ~ 108MHz FM band, and then use the FM receiver, plug in headphones that do not affect others. Because of its automatic power, power-off function, so with the remote control color TV is very convenient. And the power control circuit work is very small power consumption, does not work without electricity.
