Mic Mixer Circuit Board

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.

Mic mixer circuit board.

5 out of 5 stars based on 1 reviews 1 ratings current price 89 99 89. The full output of the mixer circuit is vout rf v1 r1 v2 r2 v3 r3. Digital mixing consoles use digital signal processing concepts and analog mixers are usually based on op amps electronic circuits. This required a larger gain on my microphone than on my music input channel.

Low impedance microphone amplifier low impedence microphone are cheap and having more availability in the market. Here is a simple 3 input mic mixer circuit using the popular ua 741 ics. Four 741s are used here ic1 ic2 ic3 are used as preamplifiers. 6 input mixer mitedu the mixer circuit below has 3 line inputs and 3 mic inputs.

A printed circuit board with this low noise amplifier can be obtained. The ic4 is wired as a summing amplifier to add the signals from three preamplifiers ic4. 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. They produce a gain of around 40 decibel to the individual input signals.

2 line output combiner convert consumer equipment stereo signal to mono or combine audio signal from two different equipments to1 input. Lt is extremely narrow to allow it to be applied as an input module within a mixer. Audio schematics mixer circuits. Home circuits a audio mixer circuits.
