Sound Activated Relay circuit (see electronic schematic) To capture the sounds, we use a microphone capsule and a small microphone preamplifier. The signal from the microphone is applied (through C1), to the non-inverting input (pin 3) of the IC1 operational amplifier. IC1 is used as a precision half-wave rectifier.

The 4066 has a buffered gate and will hard switch. The 4051, 4052, 4053 are mux bidirectional switches that can switch analog or digital, even video signals. The 4051 is a 1-of-8 switch, the 4052 is a 2-of-4 switch (great for stereo), and the …

Use gold plated cotact relays specified for low level switching, these relays have a minimum current of say 10uA. If silver cotacts are used, they will become noisy and fail after time, the arcing when they switch cleans off the tarnish on the contact faces, and this will not occur with a CD player etc. output. Telecomms. spec. relays should be ...

Audio activated delay switch is a circuit that can activate a relay switch for a specific time period. For example, when we are listening to an FM radio station there’s a sudden increase in volume when any advertisement or song plays. But with the help of this circuit that sudden increment of volume can be muted for 15 seconds and if the ...

This needs to be accomplished with the Output Select DPDT switch. When the switch is activated the resistive shunt relay would need to activate half a second before the output relay switches and release half a second later. This process will occur each time the switch is pushed in or out. I will have 24 volts to activate the relays and the circuit.

I can shield the relay(s) easily enough, but the audio signal will be close to the 12v relay coil no matter what I do. I'm thinking that perhaps the relays need to be transistor based, without mechanical coils, but that's well beyond my skill levels to design. I could build a circuit if I had a schematic.
