audio priority circuit « on: August 24, 2012, 03:00:16 pm » Hi, I'm looking for a circuit with 2 inputs and 1 output that would switch of input 1 and switch on input 2 whenever a certain threshold is reached on input 2.
Priority Audio Switch - PAS
https://www.dcbnet.com/datasheet/pasds.html
For a typical installation using 4-wire E&M circuits, the Priority Audio Switch takes in two 4-wire E&M lines with the M-lead for switch control. The ports are paired as Priority and Secondary. The “Priority” will seize control of the audio channel when the E-lead into the PAS turns on. The E-lead input is the M-lead output of a channel ...
Audio Voice-Over Circuit
http://www.zen22142.zen.co.uk/Circuits/Audio/v_over.htm
This is a circuit where a microphone and preamp circuit (voice circuit) have priority over any other audio signal. You can think of this as a one way intercom, if the main amplifier is used for listening to music, then when the push to talk switch is …

Voice-Over Circuit. In its simplest form, a voice-over unit is just a microphone and change-over switch feeding an amplifier, the output from the microphone having priority over the amplifiers audio signal when the "push-to-talk" switch is pressed. In this circuit, a preamplifier immediately follows the microphone and is designed to be used ...

The circuit below is an example of a simple audio switch: Values are not critical so experiment for best results. The 2N2222 or any signal NPN transistor is used to invert the control logic if required. Note there is no power required except to the 33k pullup resistor. This voltage can be from +5 to +15 volts.

What is a Priority Encoder?
https://www.tutorialspoint.com/what-is-a-priority-encoder
The priority encoder is a circuit that executes the priority function. The logic of the priority encoder is such that two or more inputs appear at an equal time, the input having the largest priority will take precedence. The truth table of a four-input priority encoder is given in the table. The X’s in the table designate don’t care ...
