AUDIO_MIXER


Posted on Feb 6, 2014

An audio mixer is a handy circuit that will combine two or more audio signal sources into one signal channel. The figure shows an audio mixer that is built around the LM3900 CDA. The crux of this circuit is the three input networks, principally R3, R4, and R5. These resistors are connected to different input sources (labeled VIN1,VIN2, and VIN3). Those thr..
