Elevate your audio projects with the VR 50K-2 Motorized Volume Control. This specialized component combines a high-quality dual-gang stereo potentiometer with an integrated DC motor, allowing for both manual and remote-controlled volume adjustments. Rated at 50KΩ (50KB-2), it is the industry standard for high-end hi-fi amplifiers, receivers, and home theater systems where physical knob movement must synchronize with remote control commands.
Integrated DC Motor: Features a compact, low-noise motor that physically rotates the potentiometer shaft for seamless remote-controlled operation.
Dual-Gang Stereo Control: The 50KB-2 configuration manages two audio channels simultaneously, ensuring perfectly balanced stereo output.
Manual & Automatic Versatility: The knurled metal shaft allows for traditional manual tuning while the motor handles automated adjustments.
Precision PCB Terminals: Equipped with multi-pin vertical terminals designed for secure through-hole mounting on professional audio circuit boards.
High-End Build Quality: Constructed with a durable metal housing and a stable resistive element to minimize signal interference and noise during rotation.
The VR 50K-2 Motorized Potentiometer is perfect for:
Hi-Fi Stereo Amplifiers: Adding remote volume functionality to custom or vintage audio builds.
Home Theater Receivers: Synchronizing physical volume knobs with digital control interfaces.
Studio Equipment: Enabling automated level fading and remote gain control in professional mixing environments.
Smart Home Integration: Connecting manual audio controls to microcontrollers (like Arduino or ESP32) for IoT audio systems.
Model: VR 50K-2
Type: Motorized Dual-Gang Potentiometer.
Resistance: 50KΩ.
How do I power the motor?
The integrated motor typically operates on a low-voltage DC supply (often 4.5V to 6V). You will need a motor driver circuit or a specialized remote control module to handle the bidirectional current.
Does the knob still turn by hand?
Yes. The internal clutch mechanism allows you to manually turn the volume knob even when the motor is not powered, without damaging the internal gears.
Can I use this with an Arduino?
Absolutely. By using a small H-bridge motor driver, you can program an Arduino to rotate the potentiometer to specific levels based on sensor input or IR remote commands.
