Commentary
A TV sound multiplex broadcasting tuner that can enjoy sound multiplex simply by connecting to a stereo and combining with a TV.
We have achieved low distortion and low noise sound quality by adopting a separate carrier system in which video and audio signals are IF-amplified and detected by a separate dedicated circuit.
It is equipped with an RF converter that enables simultaneous channel selection of video and audio. The channel on the video side can be switched simultaneously with audio by channel switching of ST-200V.
It is equipped with an antenna switching switch that transmits the signal from the TV antenna directly to the TV.
A total of 9 preset UHF/VHF channels can be selected.
It has a built-in program automatic switching circuit and automatically switches between stereo broadcast transmission and 2-language broadcasting.
