5 Channel Audio Mixer Circuit Diagram

Good frequency response.

5 channel audio mixer circuit diagram.

The power supply and audio power amplifier circuits are shown in figs 3 and 4 respectively. The circuit can mix as many or as few channels as you like and consumes very little power. This circuit is a simple mixer circuit. The mic inputs are suitable for low impedance 200 1000r dynamic microphones.

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. These parts must be wired as shown in the above circuit diagram connecting r3 and r4 to pin 2 and pin 6 of ic1 for right and left channel respectively. Low input current 30na open loop gain is very high. It can mix two signal channels and one channel is output.

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. In this audio mixer circuit transistor 2n2222a is the heart of the circuit. This simple circuit mixes two or more channels into one channel eg. If the supply circuit is far from audio mixer circuit then connect a 100uf 60v capacitor between supply and ground pins.

P1 p2 r1 r2 r3 r4 c1 and c2. The output is provided across a 22uf capacitor. Block diagram of the audio mixer with bass. Audio mixers can be analog or digital type.

Multi channel audio mixer circuit features. Digital mixing consoles use digital signal processing concepts and analog mixers are usually based on op amps electronic circuits. Stereo to mono converter based on fet october 3 2010. A music generator ic is used to produce high frequency musical sound which will be then mixed with the audio mixing circuit.

Stereo vu circuit stage and general purpose. Table of contents 1 simple fet audio mixer circuit 2 audio mixer by ic lf353 3 3 ch mic preamplifier with mixer using lm348 4 micro. The audio mixing circuit alone is a very simple summing amplifier. This audio mixer circuit can be powered between 5 to 30v.

The emitter is connected with gnd and the collector is connected with a 3 9k resistor. The mixer circuit below has 3 line inputs and 3 mic inputs. An ecm or condenser mic can also be used but must have bias applied via a series resistor. Audio mixer circuit diagrams.

Each channel added to the mixer must include the following additional parts. 5 stage dj mixer five stages are employed within the layout. 1 shows the block diagram of the audio mixing system along with the audio power amplifier while the circuit of the audio mixer along with a tone controller is shown in fig. Using a codec circuit convert stereo audio to mono audio time.

Wide supply voltage range. This is a universal 4 channel dj audio mixer project that may be customized and upgraded to 5 channel or even 10 channel level as desired by the user.
