LM3900 Audio Mixer
This audio mixer circuit doesn’t use a low impedance input to mix no ideal sources, but use many amplifiers to provide ideal sources before mixed through simple resistors. Ideal source means a sources with low impedances, make the interaction between signals in the output doesn’t affect the input. Please note that this mixer circuit has …[Read More]
Discrete (Transistors) Audio Mixer
This audio mixer is built with transistors. This audio mixer circuit is unique, not based on low input impedance amplifier. Most of audio mixer circuit is based on low impedance amplifier, so a high resistance signal source point can be summed together without disturbing each other. This mixer circuit is different, since the circuit is …[Read More]
