Product Information
Eliminate voltage drop and signal degradation in your large-scale lighting projects with the Miboxer PA4 4-Channel High-Performance Amplifier. Designed for extending long runs of low-voltage LED strips, the PA4 acts as a powerful signal repeater. It takes the PWM signal from your main LED controller and re-transmits it with fresh power, ensuring the last LED is just as bright and color-accurate as the first. Its versatile 4-channel design makes it the perfect solution for boosting signal to RGBW, RGB, CCT, or even four separate single color LED strip lights. For any ambitious high performance LED lighting installation, the PA4 is an essential component for achieving flawless, uniform illumination from end to end.
Key Features
Versatile 4-Channel Output
Compatible with a wide range of 4-pin lighting, including RGBW, RGB, dual-white CCT, and single-color LED strips.
Powerful Signal Amplification
Delivers a robust 6A per channel (15A total max) to combat voltage drop and maintain consistent light quality over extended distances.
Wide Voltage Compatibility
Seamlessly integrates with both DC12V and DC24V LED lighting systems, offering flexibility for various project requirements.
Perfect Signal Synchronization
Maintains perfect synchronization of color changes and dynamic effects between the controller and all connected strip sections.
Cascadable for Unlimited Extension
Multiple PA4 amplifiers can be connected in series, each with its own power supply, to extend your lighting installation to any required length.
Compact & Secure Installation
Features a compact footprint and secure screw-down terminals for a reliable, professional, and easy-to-conceal installation.
Technical Highlights
- Ensures consistent brightness and color accuracy across long LED strip runs.
- Cascadable design allows for theoretically unlimited extension of lighting projects.
- Supports high-frequency PWM signals from controllers for flicker-free performance.
- Screw-terminal connections provide secure and reliable wiring for professional installations.
- Common anode configuration for broad compatibility with standard LED strips.

Application Scenarios
How to Install & Use This LED Amplifier
- Ensure all power is disconnected before beginning installation.
- Connect a separate DC12V-24V power supply to the amplifier's 'POWER' input terminals, matching V+ and V- correctly.
- Connect the signal output wires from your main LED controller to the 'SIGNAL INPUT' side of the PA4 amplifier (V+, R, G, B, W).
- Connect the beginning of your new, extended LED strip section to the 'SIGNAL OUTPUT' side of the PA4 amplifier (V+, R, G, B, W).
- Double-check all connections for correct polarity and secure contact in the terminals.
- Restore power to the system. The extended LED strip should now perfectly mimic the color and brightness commands sent from your main controller.
- Always use a power supply with adequate wattage to support the LED strip connected to the amplifier's output.
- The input voltage of the amplifier, power supply, and LED strips must all match (e.g., all 24V).
- Do not exceed the maximum load of 6A per channel or a total of 15A for the entire amplifier.
- This device is a signal amplifier, not a standalone controller. It must be used in conjunction with a primary PWM LED controller.

Frequently Asked Questions
Q: What is the purpose of an LED amplifier?
A:An LED amplifier, or signal repeater, boosts the control signal and provides new power for long LED strip runs. This prevents voltage drop, which causes dimming and incorrect colors at the far end of the strip.
Q: Is this an RGB controller amplifier?
A:This is an amplifier that works with an RGB controller. It cannot control the lights by itself; it requires a primary controller to provide the signal that it then amplifies.
Q: Can I use the PA4 for a single color LED strip?
A:Yes, absolutely. You can connect a single color strip to one of the four channels, or you can power up to four separate single color LED strip lights, all controlled by their respective channels from the main controller.
Q: What is the difference between this PA4 and the PA5 model?
A:The PA4 is a 4-channel amplifier designed for Single Color, CCT, RGB, or RGBW strips. The PA5 is a 5-channel amplifier designed for RGBCCT LED Strip Lights, which have an additional channel for color temperature control.
Q: What size power supply do I need?
A:The power supply must be sized for the LED strip you are connecting to the amplifier's output. Calculate the total wattage of your strip segment (Length x Watts/meter) and choose a power supply rated at least 20% higher.
