Automatic Switch For Audio Power Amplifier Circuit Diagram
https://w3circuits.blogspot.com/2016/02/automatic-switch-for-audio-power.html
Automatic Switch For Audio Power Amplifier. Circuit of an automatic switch for audio power amplifier stage is presented here. The circuit uses stereo preamplifier output to detect the presence of audio to switch the audio power amplifier on only when audio is present. The circuit thus helps curtail power wastage. IC1 is used as an inverting adder.

At its basic definition relating to electrical connectors, a switch is a device for making and breaking the connection in an electric circuit. Audio jacks are available without switches, with simple switches, or with complex switching systems. These switches are often represented in a schematic for the connector available on the datasheet. Below are some typical schematics …

So, my solution to this problem, automatic audio input switcher. Basically, the system will detect which audio input has a signal, and switch to it using a solid state MUX. The project is in early state. Prototype circuit works on a breadbord. First test PCB done and sent to the factory. Then, the signal is compared to a reference voltage using ...

4013. 4066. switch. This stereo audio switch circuit allows that with only one switch to select one of the four stereo channels. The internal switching is made posible with CMOS components. Each switch input includes a voltage divider to allow the switch to work in the linear zone of the characteristics, this ensures low audio signal distorsions.
