100K Stereo Rotary Potentiometer – Dual Channel Variable Resistor 🔊

The stereo potentiometer is a dual-channel variable resistor that allows simultaneous adjustment of two independent signals with a single shaft. Commonly used in audio circuits for volume, tone, and balance control, it is also suitable for electronics projects, Arduino, Raspberry Pi (with ADC), and other microcontroller-based applications.

⭐ Key Features

• Dual-channel design: controls left and right audio channels together
• Standard 3-terminal per channel: resistive track + adjustable wiper
• Suitable for voltage divider or rheostat operation
• Available in common resistance values (e.g., 10 kΩ, 50 kΩ, 100 kΩ)
• Easy to integrate into audio devices, DIY projects, and electronic modules

📐 Technical Overview

A stereo potentiometer consists of two potentiometers operated by a single shaft. Each channel provides an adjustable resistance path, making it ideal for stereo audio control or any application requiring synchronized adjustment of two signals.

⚙️ Applications

• Stereo volume control in amplifiers, mixers, and audio modules
• Tone and balance adjustment in audio equipment
• Signal calibration in measurement and prototyping circuits
• User interface controls for DIY and professional electronics

A reliable and widely used stereo potentiometer, perfect for audio systems and electronics projects requiring dual-channel adjustable control.
