Mute circuits are also used at the inputs of many professional power amps. In some cases the signal is muted if the amp gets too hot, and nearly all mute the inputs for 1 - 5 seconds after power on. This is done so that turn-on/ off noises from mixers and other gear is blocked in case the entire system is powered up at once.

In amplifiers and pre-amplifiers, the muting circuit is intended to prevent the popping of loudspeakers when power is applied. In mixers and audio line & level equipment, the muting circuit may also be employed to select /deselect various input channels –such must be done cleanly or quietly. Types of muting circuits

Figure 1: Schematic of a simple circuit for preamp muting. The Circuit. The circuit draws its power from the raw supply rails of the existing preamp, drawing only 7mA of current; you can adjust it for a range of operating voltages by simply changing the value of the zener diode. No connection to the preamp’s GND is needed, so there’s no ...

While playing, if their is any sound into microphone, audio will become mute. After the sound from microphone is stop, the audio will be increasing its volume rapidly to its initial volume for some seconds. So, can you guide me some sir? This circuit is connected directly to amplifier, if possible it uses power supply from amplifier.
where to place mute circuit? - diyAudio

Your audio output is taken from the other end of the resistor. Doing it this way ensures that the opamp can stabilise its DC conditions correctly, and placing the relay at the output ensures silent operation. Muting the inputs probably wouldn't achieve much. Resistor can be as low as 22 ohm or so. J jimmy audio Member 2010-07-20 3:56 pm

The circuit should mute sufficiently any audio from 15 hz to 20 khz. Mute level should *easily* reach -50db. If not, you don't have the circuit wired correctly. This circuit will also fade by providing a variable voltage at the junction of the 33k and 1M0 resistors (R3 and R4). The fade will be low in distortion until -20 db has been reached.

Muting Relay PCB. DIY Audio Home. Muting relay PCB. NOTE: The BOM and schematic incorrectly calls out 1N5821 rectifier diodes. These don't mechanically fit on the PCB. use 1N5817 or silimar 1A diodes instead. With cap-coupled preamps and single-ended power amps in particular, there is often a "thump" heard in the speakers when powering up. I switch the power to my entire …
