3 Channel Audio Mixer Circuit - .

This audio mixer circuit uses an LM3900 IC but is not a profesional audio dj mixer. The IC houses four integrated Norton amplifiers. The advantage of using the four op amps is that they only need a single power supply. Since this amplifier circuit is current controlled, the DC bias is dependent on the feedback coupling. The schematic diagram shows inverting AC-Norton amplifiers. The DC output ...

How to...Connecting stereo outputs to mono input

The passive mixer should be transformer-coupled, but even simple resistor-based mixer circuits are a VAST improvement over the directly-paralleled coupling of the stereo signals. And the resistor-type "circuit" is really just a few inexpensive, readily-available resistors. The resistors can be wired such that they could be fit INSIDE the XLR or directly onto the euro-block connector. There are ...
