Audio Signal Detector/Switch Circuit designed by David A. Johnson, P.E. For some audio systems it is desirable to have an automatic switch circuit turn on other devices, such as an Amplifier, if an audio signal is detected on one line. The hobby circuit below will activate a transistor switch when it detects at least 50mv peak to peak of an ...

Two similar circuits: A) Automatic input selector: If input A is connected to the output, if input B has audio signal the circuit switches to input B. B) Detect audio signal to switch relay on and after some time off again when the music has stopped.
What component to use for audio signal switching?

Now, I need to switch audio signal obviously and I need to do it quietly (both physical silence and electrical silence). Please note that the signal is line level throughout most of the build, except for the input which is much lower. I will probably have 2 or 3 loops before the preamp so those may not encounter line level signal.

Audio signal #1 would go the #1 switch input and audio signal #2 would go to the #2 switch input. Thus, when you change logic-levels (low to high, or high to low) the circuit output (where both the #1 and #2 switch outputs are tied together), the output will be audio signal #1 for a high and audio signal #2 for a low.

Because RF signal levels are typically fairly low compared to audio levels, distortion isn't generally a problem, and they can switch very quickly if DC offset isn't an issue. This is usually easily dealt with in RF circuits, and very low capacitance values work because the frequency is high (several MHz up to GHz).
