The Passive Attenuator is a purely passive resistive network (hence no supply) which is used in a wide variety of electronic equipment for extending the dynamic range of measuring equipment by adjusting signal levels, to provide impedance matching of oscillators or amplifiers to reduce the effects of improper

Jul 13, 2016. #1. I'm working on building a passive attenuator for use eventually as a simple Arduino-controlled volume controller. I've found a similar schematic called the RelaiXedPassive Attenuator. It uses an attenuator ladder arrangement, using 6 relays to provide 256 steps of attenuation. I've started assembling it and testing it out with ...

Lightspeed Passive Attenuator. The Lightspeed Passive Attenuator designed by George Stantscheff (GeorgeHiFi on the audio forums) is by far the very best passive attenuator that I have heard. There is perfect clarity, a widened soundstage, separation of instruments, and seemingly infinite detail.

What is Attenuators? Attenuators are passive devices. It is convenient to discuss them along with decibels. Attenuators weaken or attenuate the high level output of a signal generator, for example, to provide a lower level signal for something like the antenna input of a sensitive radio receiver. (figure below) The attenuator could be built into the signal generator, or be a stand-alone device.
RelaiXedPassive -- audio attenuator - van Eijndhoven
http://www.vaneijndhoven.net/jos/relaixedpassive/
It is an audio volume control and input channel selector with a minimalistic passive design: there are are no active parts in the audio path: no transistors, opamps, tubes. It is a true attenuator, and it does not add any distortion to the audio signal. This attenuator design inherits important concepts of my earlier RelaiXed preamplifier designs:

There are very simple gadgets that can be used for audio purposes with great results. These are passive attenuators. They are very simple objects based on a resistive partition housed in male-female RCA connectors and can be used in particular when there are differences in sensivity between the source (CD player, preamp, etc.) and the amplifier.

But even with the tapper audio transformer changing the impedance in secondary does reflect in changing of input impedance , so : every passive attenuator do suffer from variable input impedance whatever circuit do you use !!! Only active attenuator ( like this : Input --->buffer-->attenuator--->buffer--->output ) have a constant input and ...
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 …
