2-Channel Audio Panning Circuit Diagram

Introduction

The panoramic control circuit, also known as panning circuit, enables the user to alter the position of a single microphone input between two output channels. This functionality of 2-Channel Audio Panning Circuit is frequently used in mixing consoles within recording studios. By utilizing panning, recording engineers can achieve the effect of placing a pianist’s sound on one side of the stage and then move it to the other side.

Audio panning is a widely used technique that creates the illusion of sound moving from one speaker to another and is commonly used in music and multimedia production. A 2-channel audio panning circuit allows for two-channel stereo input to be panned or moved in a specific direction using a single IC (integrated circuit). The LM387 is a popular choice for creating this circuit as it offers low distortion, high gain, and easy to use features. This diy circuit is one of the simple electronic projects or an easy electronic projects. In this website you will find most of the circuit projects for beginners and easy electronics projects.

Design Explanation of 2-Channel Audio Panning Circuit

The LM387 IC consists of two independent operational amplifiers, each with a gain of 2. The circuit will use one of these operational amplifiers to amplify the audio signal and the other to attenuate the signal. By adjusting the amplitudes of each channel, the signal can be panned left or right.

The circuit will have two audio inputs, with one being panned left and the other being panned right. The inputs are first passed through a high-pass filter to remove any DC voltage and then mixed together. The mixed signal is then fed into a pre-amplifier with a gain of approximately 20 dB.

The output of the pre-amplifier is then split into two channels, each of which is amplified by the operational amplifiers. By adjusting the gains of each channel, the signal can be panned left or right, with a balance control used to adjust the overall balance of the stereo output.

Conclusion of 2-Channel Audio Panning Circuit

A 2-channel audio panning circuit using the LM387 IC is a simple and effective way to add panning effects to a stereo audio signal. With a few simple adjustments to the circuit, the signal can be panned left or right, and the balance control can be used to fine-tune the overall mix. This circuit is an excellent choice for anyone looking to add professional-grade audio effects to their stereo output.
