How to Build a Simple Attenuator Circuit. 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.

This attenuator design has the following features/characteristics: Compact and simple circuit: just 6 tiny relays implement a 64-step logarithmic stereo attenuator. The 64 steps of 1.0dB together span a 63dB audio attenuation range. By avoiding any active electronics, a very clean and open sound is maintained. An IR receiver allows remote control.

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 …

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.

Summary: Attenuators. An attenuator reduces an input signal to a lower level. The amount of attenuation is specified in decibels (dB). Decibel values are additive for cascaded attenuator sections. dB from power ratio: dB = 10 log10(PI / PO) dB from voltage ratio: dB = 20 log10(VI / VO) T and Π section attenuators are the most common circuit ...
