This audio mixer circuit uses an LM3900 IC but is not a profesional audio dj mixer. The IC houses four integrated Norton amplifiers. The advantage of using the four op amps is that they only need a ...

This audio mixer circuit schematic we propose here is built around four amplifiers, which are current controlled, all of them incorporated in IC SSM2024, produced by Precision Monolithics Inc. (PMI).

In audio systems, the mixer provides a consistent signal that can be routed out to speakers, amplifier, recording equipment or headphones. A mixer signal is typically not amplified, or if it is, ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...
