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.

All the parts are easy to find, and for a few hours’ work and relatively little outlay you can build an attenuator that would cost £100 or more to buy. All you really need is pliers, a soldering iron, an electric drill and a step cutter bit. The …

Output audio connectivity: One stereo audio signal through a 4-pin screw connector: Input audio connectivity: Four stereo inputs, typically through an on-board 4x2 cinch (RCA) connector block: Input resistance: 27Kohm (can be reconfigured to any other value) Output resistance: 0 to 13Kohm, varies with the volume selection: Frequency bandwidth:

It’s quite easy and inexpensive to build your own inline mic or line passive attenuator within something like the S3FM XLR barrel (image below). Resistor values will vary depending on the dB of attenuation desired and the impedances of the gear on either end. Uneeda Audio hosts a great tutorialon how to build a pad into an XLR barrel.

Re: Building a passive preamp/attenuator I built this passive using an Alps pot and RCA's purchased from Partsconnexion.I used 10k as I think it gives the best comprimise between input and output impedance.

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 configurations.

Jul 5, 2020. #1. Hi all, Just wondering if you amazing folks could recommend some good attenuator for a passive pre-amp project. Using Hypex module for power amp part thus don't really want the attenuator to ruin the SINAD. Ideally < $50, thanks.
