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.

The PCM510xA devices have two auto-mute functions to mute the device upon power loss (intentional or unintentional). XSMT = 0 When the XSMT pin is pulled low, the incoming PCM data is attenuated to 0, closely followed by a hard analog mute. This process takes 150 sample times (ts ) + 0.2 ms.

Potentiometer R 2 , set to twice Q 1 's cutoff voltage, makes the on/off transition times roughly equal. R 2 and D 3 quickly discharge C 1 and mute the signal during power-down. For this process to work, the signal path should remain stable to below roughly one-third the normal supply voltages—below ±4V in this example. Q 1 can then finish muting.

To effectively mute all signal frequencies, the value of C should be properly selected: C >> 1/ (2 × Π × f × R1) where f is the signal’s frequency. To avoid loss of gain, R should be much, much...

Sound Activated Automatic Amplifier Mute Circuit. The following article presents a simple sound operated/activated amplifier muting circuit which enables the amplifier to silence itself as soon a voice or an external sound occurs across the detector MIC. The circuit was requested by Mr. Seok Sothea.

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.
