Passive Audio Attenuators Jul 24, 2004 12:30 AM, By Chriss Scherer Once in common use in radio, the passive attenuator is used less frequently today because of active circuitry and bridging impedances instead of matched impedances. The basic attenuator is a T pad, which provides an unbalanced attenuator path referenced to ground.
The Passive Attenuator - MegaOhm Audio
http://www.megaohmaudio.com/images/PassiveAttMult1.pdf
Passive meaning no power required. Attenuator meaning any input signal will be let through unchanged or turned down to zero by rotating the pot counter clockwise. It does not boost the input signal. It is very useful as part of a utility module. Also, the passive attenuator (minus the output jack) is found on almost every module.

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.

Passive Attenuator anyone? - Part-Time Audiophile

The Oppo BDP-95 can easily drive a passive preamp (it can drive as little as 600 ohms). I’ve already sold my complicated, noisy, compromised, costly receiver! The heart of any passive preamp is the potentiometer or switched attenuator. Good ones aren’t cheap. I sourced mine from Goldpoint level controls.

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 ...

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.
