Build an Audio Mixer Projects All About Circuits I measured the max output of my microphone at 2 Vpp (on battery power) and my tablet's max output was measured at 3 Vpp. This required a larger gain on my microphone than on my music input channel. The full output of the mixer circuit is Vout = Rf(V1 R1 V2 R2 V3 R3 . . . Vn Rn). Thus, by making RF larger the gain can be increased. How to build an audio mixer An audio mixer, also called a mixing console, is an electronic device for combining, and modifying audio signals.The modified audio signals are summed to produce some combined output signals. Audio mixers can be analog or digital type. Digital mixing consoles use Digital Signal Processing concepts and analog mixers are usually based on op amps electronic circuits.
