4-channel input selector for audio amplifier. It is equipped with RCA connectors and is controlled by a rotary switch connected to the selector plate with a tape. It allows you to select one of the signal sources fed to the selector inputs, which is sent to the output. The currently selected source is signaled by one of the LEDs on the switch board. The module is powered with AC voltage in the range from 12 to 15 V. It will be used in the projects of audio players.
