Audio Mixer Passive Attenuator Circuit. Ask Question Asked 5 years, 9 months ago. Active 5 years, 9 months ago. Viewed 724 times 2 \$\begingroup\$ I'm currently designing a digital audio mixer. One common thing found on audio mixers is a optional 20dB pad on the input. I've seen some attenuator circuits but all of them require you to know your ...

Four Channel Audio Passive Stereo Mixer

A passive mixer is an audio mixer that doesn't require any power because it doesn't have an amplifier. It's a circuit of audio jacks with potentiometers that are wired up to let the audio input signals flow to an audio output. This build uses stereo potentiometers and stereo TRS audio jacks to accommodate both mono and stereo devices.

“Passive” Current Mixer +LO −LO +IF −IF +RF −RF +LO The input stage is a Gm stage similar to a Gilbert cell mixer. The Gilbert Quad, though, has no DC current and switches on/off similar to a passive mixer. The output signal drives the virtual ground of a differential op-amp. The current signal is converted into a voltage output by ...

There's no difference per se - the kind of topology where you have a "passive mixer and gain stage" in one circuit is just one way of doing an "active mixer". One used by plenty of Eurorack manufacturers for example. ... FWIW on the pro audio (DIY) side of things some people seem to be really fond of idea of passive summing with bring-your-own ...

Resistor values for a passive audio mixer? - Electrical ...

https://electronics.stackexchange.com/questions/175678/resistor-values-for-a-passive-audio-mixer

I'm trying to come up with a schematic for building a passive audio mixer for an aviation headset, but I'm having some questions about resistor values. Figuring out the general circuit is easy enough, but I'd like to bounce this off people who know a lot more than I do so I can make sure I'm doing this right.

Simple Mixer Schematics - ALL ELECTRIC

What is required is a little load isolation. (See Circuit 1: Passive mixer) The trade off is that you can't use terribly high value resistors because of the losses that they may cause. Especially if the load impedance of the following device is a little low. This will give the effect of severely attenuating some or all of the signals.
