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.

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.

each amplifier's internal differential pair, resulting in an output DC shift towards Vsupply. An R-Ctiming circuit should be used to limit the pull-downtime such that output “pops” and signal feedthroughs will be minimized. The MUTE

Right then my latest weird and wacky circuit involves the control of a the mute function on an AN5279 Amplifier chip. The amplifier circuit itself is very simple requiring only a minimum of parts to get it running. This project will run on 12VDC. 2 pins of the chip require 5V as a control voltage. The standby pin needs 5V +VE for the amplifier ...
where to place mute circuit? | diyAudio

jimmy audio. Where is the best place to implement a relay based mute circuit? right at the input jacks before the summing amps/volume control or after the summing amps/volume control right before the amps (6x)? Relays (3x dpst) will short the inputs to ground. Kinda worried about shorting the op amps outputs (JRC 2068dd) to ground.

This is a scope shot of the output of "el escorpion" (before the muting circuit) showing power-up with cold tubes. The output goes through a ~1V "bump" as the tubes start conducting. This is a low-frequency thump. If you are using an amplifier and speakers with poor low frequency response, it might not cause you too much of a problem.
