SIGNAL_COMBINER

This circuit uses buffer stages to prevent channel crosstallk back through the mixer resistor network.The potentimeters used for each stage allow for convenient signal strength adjustment, while maintaining input impedance matching at the 600-Ω audio standard.The feedback resistor Rf will permit the output signal gain to be as high as 15 dB.
