Voltage Controlled Audio Mixer Circuit

This audio mixer circuit schematic is designed around four current-controlled amplifiers, all integrated within the SSM2024 IC.

The audio mixer circuit utilizes the SSM2024 integrated circuit, which features low-noise, high-performance operational amplifiers suitable for audio applications. The SSM2024 is particularly advantageous due to its ability to provide high gain with minimal distortion, making it ideal for mixing audio signals from multiple sources.

In this schematic, each of the four amplifiers serves as a channel for audio input, allowing for the mixing of different audio signals. The configuration typically includes input resistors that set the gain for each channel, along with potentiometers to allow for adjustable volume control for each input.

The output of each amplifier can be fed into a summing stage, which combines the individual audio signals into a single output signal. This summing stage is essential for ensuring that the mixed audio maintains a balanced output level and clarity. Capacitors may be included in the output stage to block any DC offset, ensuring that only the AC audio signal is passed to the subsequent processing stages or to the output device.

Power supply considerations are also critical in this design. The SSM2024 requires a dual power supply, typically +15V and -15V, to operate effectively. Proper decoupling capacitors should be placed near the power pins of the IC to filter out any noise that may affect audio quality.

Overall, this audio mixer circuit schematic provides a robust solution for mixing multiple audio signals, leveraging the capabilities of the SSM2024 integrated circuit to achieve high fidelity and low distortion in the final output.This audio mixer circuit schematic we propose here is built around four amplifiers, which are current controlled, all of them incorporated in IC SSM2024, p.. 🔗 External reference
