Four-input stereo mixer


Posted on Jun 19, 2012

Four (or more) inputs can be mixed and produce stereo output. Gain of each stage can be boosted by adding RX, but it should be kept below 50 (RX above 2 K) to avoid poor frequency, response. If more than four stages are used, decrease RXto 6 K for six inputs, or 4 K for eight inputs
