3. Product Features

3.1 True Isolated Power Supply

The MPP-10 features true isolated outputs, meaning each output channel is electrically separated. This design prevents unwanted noise and hum from affecting your pedals, providing a clean and stable power source for optimal audio performance.

3.2 Short Circuit and Over-Current Protection

Each of the 10 output channels is equipped with independent short-circuit and over-current protection. In the event of a short circuit on one output, only that specific output will be affected, and its LED indicator will turn off, while other channels continue to operate normally.

3.3 Adjustable Voltage Outputs

Two dedicated output ports (9 and 10) offer adjustable voltage settings of 9V, 12V, or 18V, each providing up to 500mA. This allows compatibility with a wider range of effect pedals that require different voltage inputs.

3.4 USB Charging Port

In addition to powering your pedals, the MPP-10 includes a 5V 1A USB output port, allowing you to conveniently charge mobile devices or power other USB-compatible accessories directly from your pedalboard.

4. Setup Instructions

1. Connect the Power Adapter: Plug the included 12V DC power adapter into the "POWER IN" port (red connector) on the LEKATO MPP-10 unit. Then, plug the power adapter into a standard AC wall outlet. The red "POWER" LED on the unit will illuminate.
2. Connect DC Power Cables: Use the provided DC power cables to connect your effect pedals to the output ports on the MPP-10. Ensure the correct polarity (center negative is standard for most guitar pedals). If a pedal requires center positive, use the included polarity conversion cable.
3. Select Output Voltage (for adjustable ports): For outputs 9 and 10, use the small toggle switch next to each port to select the required voltage (9V, 12V, or 18V) for your specific pedal. Verify the pedal's voltage requirements before connecting.
4. Verify Connections: Once all pedals are connected, the green LED indicator above each active output port will light up, confirming power delivery.

5. Operating Instructions

5.1 Powering On/Off

The MPP-10 unit powers on automatically when connected to the main power adapter. There is no separate on/off switch on the unit itself. Disconnect the main power adapter to power off the unit.

5.2 LED Indicators

Each output port has a corresponding green LED indicator. When a pedal is correctly connected and receiving power, its LED will illuminate. If an LED is off, it may indicate a short circuit on that channel or an unconnected pedal.

5.3 Using Adjustable Voltage Outputs

For outputs 9 and 10, ensure the toggle switch is set to the correct voltage (9V, 12V, or 18V) required by your pedal. Incorrect voltage can damage your pedal. Always consult your pedal's manual for its power requirements.

5.4 USB Output

The USB OUT port provides 5V 1A power. Connect your USB-powered device using a compatible USB cable. This port is ideal for charging smartphones, tablets, or powering small USB accessories.

7. Safety and Troubleshooting

7.1 Important Safety Information

• Always verify the voltage and current requirements of your pedals before connecting them to the power supply. Incorrect voltage can cause permanent damage.
• Ensure correct polarity. Most guitar pedals use center-negative polarity. Use the provided polarity conversion cable if your pedal requires center-positive.
• Do not expose the unit to water, moisture, or extreme temperatures.
• Do not attempt to open or modify the unit. This will void the warranty and may cause electric shock.

7.2 Troubleshooting

• No Power to Pedal:
  • Check if the main power adapter is securely plugged into the wall and the MPP-10.
  • Ensure the DC power cable is firmly connected to both the MPP-10 output and the pedal.
  • If using an adjustable output (9 or 10), confirm the correct voltage is selected.
  • If the LED for a specific output is off, a short circuit may have occurred. Disconnect the pedal and cable from that output and check for faults.
• Unwanted Noise/Hum:
  • The MPP-10 features true isolated outputs to minimize noise. If hum persists, check your guitar cables, instrument, and amplifier for other potential noise sources.
  • Ensure all connections are secure and free from damage.
