Key Features:
- Music/Sound Synchronization Effects: Features a built-in high-sensitivity microphone to capture audio signals, allowing LED lights to react to music rhythm. Includes 18 music effects (e.g., full-color rhythm spectrum, gradient energy, Christmas, beat, party). Adjustable length, brightness, and sensitivity.
- Rich Color Modes (Non-Music): Offers 142 built-in dynamic effects (e.g., rainbow, twinkling stars, waves) and numerous static color effects. Adjustable speed, effect length, and brightness. Allows saving up to 9 favorite effects and precise RGB color spectrum adjustment in static mode.
- Timer Function: Schedule LED lights to turn on/off automatically at specified times, frequencies, and channels. Supports up to 5 timing events. Note: All timing events are deleted when the ECU is powered off.
- IC Driver Model Support: Compatible with most LED driver ICs on the market, including WS2811, WS2812B, SK6812RGB (SK6812RGBW not supported), and US1903. Controls up to 600 pixels.
- Easy Control Methods: Operable via the control box, mobile application (iOS 10.0+ and Android 4.4+), and infrared remote control.
2. Setup and Installation
Before installation, ensure all components are present and the LED strip is compatible with the controller's voltage requirements. The controller operates on 5-24V DC, which must match your LED strip's voltage. For example, a 5V LED strip requires a 5V power supply.
2.1. Wiring Connections:
- Power Supply Connection: Connect a compatible DC power supply (5-24V, depending on your LED strip) to the controller's DC input port. Ensure correct polarity.
- LED Strip Connection: Connect your addressable LED strip to the controller's output port. The controller supports 3-pin LED strips. Ensure the data, ground, and power lines are correctly aligned.
- IR Receiver: The controller includes an IR receiver for the remote control. Ensure it is not obstructed for optimal remote performance.

2.2. App Installation:
To utilize the full features of the SP611E controller, download the dedicated mobile application.
- Scan the QR code provided on the controller unit or in the product packaging to download the app.
- Alternatively, search for the app name (usually indicated in the product manual or packaging) in your device's app store (Apple App Store for iOS, Google Play Store for Android).
- Ensure your device meets the minimum OS requirements: iOS 10.0 or later, Android 4.4 or later.
- Enable Bluetooth on your mobile device and open the app. The app should automatically connect to the controller.
3. Operating Instructions
3.1. App Control:
The mobile application provides comprehensive control over your LED strip. Once connected, you can:
- Music Synchronization: Select from 18 music effects. The built-in microphone will pick up sound, and the lights will react. Adjust sensitivity, brightness, and effect length.
- Dynamic Modes: Choose from 142 dynamic effects like rainbow, waves, and twinkling. Customize speed, length, and brightness.
- Static Colors: Select a single color from a wide spectrum. Fine-tune RGB values for precise color selection.
- Timer Function: Set up to 5 scheduled events for automatic power on/off.
- Device Management: Rename the device, calibrate RGB channel sequence, and manage grouping for multiple controllers.
3.2. IR Remote Control:
The 38-button IR remote provides direct control without needing the app. Ensure the remote has a battery (not included) and is pointed towards the controller's IR receiver.

Key remote functions include:
- ON/OFF: Power the LED strip on or off.
- Color Buttons: Directly select various static colors (R, G, B, W, and other preset colors).
- Mode Buttons: Cycle through dynamic effects.
- Brightness/Speed Adjustment: Increase or decrease brightness for static colors, or speed for dynamic effects.
- Music Modes: Activate various music synchronization effects.
- Length Adjustment: Adjust the length of certain effects.
4. Maintenance
To ensure the longevity and optimal performance of your SP611E controller, follow these simple maintenance guidelines:
- Keep the controller and remote clean and dry. Avoid exposure to moisture or extreme temperatures.
- Do not place the controller near heat sources or in direct sunlight.
- Ensure proper ventilation around the controller to prevent overheating.
- When replacing the remote control battery, use the specified type (battery not included with product).
- Avoid physical impact or crushing of the controller unit.
5. Troubleshooting
If you encounter issues with your SP611E controller, please refer to the following common troubleshooting steps:
- LED Strip Not Lighting Up / Partial Lighting:
- Verify that the power supply voltage matches the LED strip's voltage (e.g., 5V strip needs 5V power supply). Incorrect voltage can damage the LED strip and controller.
- Check all wiring connections (power, data, ground) between the power supply, controller, and LED strip for secure and correct polarity.
- Ensure the LED strip itself is functional by testing it with a known working controller or power source if possible.
- Confirm the LED strip's IC model is supported by the SP611E (e.g., WS2811, WS2812B, SK6812RGB). SK6812RGBW is not supported.
- Remote Control Not Responding:
- Ensure the remote has a working battery and it is inserted correctly.
- Point the remote directly at the controller's IR receiver and ensure there are no obstructions.
- Try operating the controller via the mobile app to confirm the controller unit is functional.
- App Connection Issues:
- Ensure Bluetooth is enabled on your mobile device.
- Restart the app and/or your mobile device.
- Ensure the controller is powered on.
- Check if your mobile device's operating system meets the minimum requirements (iOS 10.0+, Android 4.4+).
- Music Sync Not Working:
- Ensure the built-in microphone on the controller is not obstructed.
- Increase the volume of the music source.
- Adjust the sensitivity setting within the app.
If the problem persists after trying these steps, please contact customer support for further assistance.
