How to Build a Simple Attenuator Circuit
http://www.learningaboutelectronics.com/Articles/Attenuator-circuit.php
An attenuator circuit is a circuit which attenuates, or decreases the strength of, a signal. In this project, we will build a very simple attenuator circuit using nothing but a resistor or potentiometer coupled with our circuit. Attenuator circuits are very useful for whenever we need to decrease the strength of signals.

Re: Audio Attenuator circuit. Yes. The audio signals are going through a fixed attenuator where roughly 20% of the voltage goes to the TV. Apparently the source puts out a pretty "hot" audio signal and the circuit knocks it down to a …
Homemade RCA Attenuator : 5 Steps (with Pictures ...
https://www.instructables.com/Homemade-RCA-Attenuator/
Homemade RCA Attenuator: This project arose from the fact that I had too much gain in my audio system, and I needed a practical solution without modifying the PCB circuit. The problem can be solved using an RCA (in-line) attenuator, but since a new one can be quite expensiv…

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.

This circuit provides around 20 dB of signal attenuation (typically enough to make thigns work, if more attenuation is needed use higher R1 value) and blocks the DC bias used in the electret microphone input to get to the line signal side (C1 does this).
