RelaiXedPassive -- audio attenuator - van Eijndhoven
http://www.vaneijndhoven.net/jos/relaixedpassive/
The design comes with complete schematics and open source code of the embedded controller software. The avoidance of clicks in the audio signal is the major improvement with respect to my original attenuator design of several years back, and distinguishes this design from relay-attenuators from some other sources. Note that a soft mechanical clicking noise is still …

The schematic for the Lightspeed Passive Attenuator is shown below. George has chosen to share his Lightspeed Attenuator with the DIY community provided that it is only used for personal use only. Details about George's commercial offering of the Lightspeed Passive Attenuator are provided at the bottom of this page.
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…
DIY Workshop: How to build your own attenuator | Guitar ...
https://guitar.com/guides/diy-workshop/diy-workshop-build-your-own-attenuator/
The complete circuit diagram for our attenuator. The L-Pad. There are myriad ways of attenuating an amplifier signal, but the vast majority of DIY attenuators are based on a straightforward circuit called an L-Pad. This method employs …
Muting Transistor Attenuator Circuits and the 2SC2878 ...
https://www.electroschematics.com/muting-transistor-attenuator-circuits-2sc2878/
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 Volume Control Attenuator with IR Control
http://electronics-diy.com/audio-volume-control-attenuator-with-ir-control.php
The circuit provides both audio volume and input channel selection. A stepwise volume control is implemented with a set of small relays and resistors. In a high-end audio system, a noticable sound improvement over potentiomeneters can be obtained, also over 'audio grade' potentiometers. Clearly, the IR remote control provides convenience over solutions with …
How to Build a Simple Attenuator Circuit
http://www.learningaboutelectronics.com/Articles/Attenuator-circuit.php
Basically, attenuators are useful in all applications in which we need to decrease the signal strength of signals. The attenuator we will build is an absolutely simple, yet effective, circuit for attenuating signals so that we can decrease the level of a signal. The parts we will use to build this circuit are: Components Needed. 10KΩ Resistor or Potentiometer; Power Source; Jumper …
Audio Attenuator circuit - Page 1 - EEVblog
https://eevblog.com/forum/beginners/audio-attenuator-circuit/
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 …
