Product title portable karaoke microphone mixer system set with d. Home circuits a audio mixer circuits. Audio mixers can be analog or digital type. Here is a simple 3 input mic mixer circuit using the popular ua 741 ics.

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. Low impedance microphone amplifier low impedence microphone are cheap and having more availability in the market. 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.

The mic inputs are suitable for low impedance 200 1000r dynamic microphones. 5 out of 5 stars based on 1 reviews 1 ratings current price 89 99 89. Four 741s are used here ic1 ic2 ic3 are used as preamplifiers. Audio schematics mixer circuits.

This required a larger gain on my microphone than on my music input channel. 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. 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.
