Soft-Action Mute Switch. This simple circuit is a line-level audio signal muting switch based on a soft-action power on/off process. When the S1 switch is closed, R4, C1 and Q4 JFET quietly ground the signal to be muted in between 100 to 200 ms and the RED indicator light goes on. When the S1 is opened the signal is released and the GREEN led ...

Applications for muting circuits. Applications for muting circuits abound. Included are synthesizers, audio amplifiers, pre-amplifiers, audio mixers and audio line & level equipment (both consumer and professional). In amplifiers and pre-amplifiers, the muting circuit is intended to prevent the popping of loudspeakers when power is applied.
Audio Switch Notes - Neat Circuits

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 Circuit Mod Recommended for Solid State Amps - $35 Here is a muting circuit that provides about a 15 second mute delay during turn-on for the Grounded Grid Preamp or any audio device that has 12 volts DC available. The circuit draws only 60 mA at 12 VDC allowing it to be installed in most any component. The circuit board is prewired.
