As with any mixer circuit, a slight loss is always introduced. The final summing amplifier has a gain of 2 or 6dB to overcome this. The Input line level should be around 200mV RMS. The mic inputs are amplified about 100 times or by 40dB, the total gain with the mixer is 46dB. 6 Channel Audio Mixer Mar 06, 2009 This is 6 Channel Audio Mixer circuit. 3 channel for microphone input and the others 3 channel for audio input like CD player, computer, or television. There will be 6 potensiometer to control the volume of each channel. Circuit Notes The mixer circuit above has 3 line inputs and 3 mic inputs. The mic inputs are suitable for low impedance 200-1000R dynamic microphones. An ECM or condenser mic can also be used, but must have bias applied via a series resistor. As with any mixer circuit, a slight loss is always introduced. In the Fig.14, exist a circuit that make the same work, but is simpler. Instead of switches, exists a double rotary switch, that select only a input channel each time. In the place of IC1, it can enter somebody from opamp. that propose, choice of that will be proportional units that will be used. Audio MIXER Audio Modular MIXER with 6 and up input Channel April 13, 2010 This you can place in the MODULES of inputs any circuit you want, depending on the use that you intend the MIXER, the same is also for the number of input channels, that you will... Home > Circuits > A > Audio Mixer Circuits: Audio Schematics Mixer Circuits: 2 Line Output Combiner Convert consumer equipment stereo signal to mono or combine audio signal from two different equipments to1-input . 3 Line Mixer. 6 Input Mixer (mitedu) The mixer circuit below has 3 line inputs and 3 mic inputs. The mic inputs are suitable for low impedance 200-1000R dynamic Jul 04, 2019 This audio mixer circuit uses two stage amplifiers with a microphone to capture and amplify the bass beats played on an external device so that it should have enough loudness when mixing with other sounds. A music generator IC is used to produce high frequency musical sound which will be then mixed with the audio mixing circuit. The audio mixing circuit alone is a very simple summing Jul 20, 2020 This circuit is a simple mixer circuit. It can mix two signal channels and one channel is output. Using a codec circuit,Convert stereo audio to mono audio time. Table of Contents Show All 1) Simple FET Audio Mixer Circuit 2) Audio Mixer by IC LF353 3) 3 CH MIC preamplifier with Mixer
