Commentary
A TV sound multiplex tuner that allows you to enjoy TV stereo broadcast transmission and 2-language broadcasting.
A built-in RF converter eliminates the channel switching operation that is a problem with independent tuners.
Connect the RF output terminal of the tuner to the antenna terminal of the TV, set it, and the sound and image can be switched by the tuning button of the tuner.
Also, if you turn off the power of the tuner, the antenna and TV are connected directly.
It uses separate carrier system, double convert system, and double pulse detection system.
