• DC IN: Connect the provided 12V 2A DC power adapter here.
• DC OUT (1-10): These are 10 isolated 9V DC outputs, each providing up to 300mA. Use the included DC power cables to connect your effect pedals.
• USB OUT: A 5V 1A USB output port for charging mobile devices or powering USB-compatible accessories.

4. Setup Instructions

1. Connect Power Adapter: Insert the DC plug of the provided power adapter into the "DC IN" port on the M-VAVE SK2 unit.
2. Connect to Wall Outlet: Plug the power adapter into a standard AC wall outlet. The blue LED indicators on the M-VAVE SK2 will illuminate, indicating the unit is powered on.
3. Connect Pedals: Use the included DC power cables to connect your guitar or bass effect pedals to the "DC OUT" ports (1-10). Ensure your pedals require 9V DC power and do not exceed 300mA per output.
4. Optional USB Connection: If desired, connect a USB device to the "USB OUT" port for charging or power.

5. Operating Instructions

Once connected, the M-VAVE SK2 operates automatically:

• Power On/Off: The unit powers on when connected to an AC outlet via its adapter. Disconnect the adapter to power off.
• LED Indicators: Each DC output port has a corresponding blue LED light. These LEDs illuminate when the channel is active and supplying power. If an LED goes off, it indicates an overcurrent condition on that specific channel.
• Isolated Outputs: Each of the 10 DC 9V outputs is independently isolated. This design minimizes ground loops and electrical noise between pedals, ensuring a cleaner audio signal.
• USB Output: The 5V 1A USB port provides power for charging smartphones, tablets, or other USB-powered devices.

6. Features and Protection

• Isolated Outputs: Each of the 10 DC 9V outputs is independently isolated, preventing unwanted noise and hum caused by ground loops between pedals.
• Noise Reduction Circuit: The unit incorporates a noise reduction circuit to ensure a clean and stable power supply, contributing to a superior audio experience.
• Independent Overcurrent Protection: Each channel features independent overcurrent protection. If one channel experiences an overcurrent condition, it will shut down without affecting the operation of other channels. The corresponding LED will turn off.
• Durable Construction: Made from lightweight and durable aluminum alloy, designed for portability and longevity.

8. Troubleshooting

• No Power/LEDs Off:
  • Ensure the DC power adapter is securely connected to both the "DC IN" port and a working AC wall outlet.
  • Verify the wall outlet is functional by plugging in another device.
• One Pedal Not Working (LED Off):
  • This indicates an overcurrent condition on that specific output channel. Disconnect the pedal from that output.
  • Check the power requirements of the pedal. If it draws more than 300mA, it cannot be powered by this unit.
  • Try connecting a different pedal to the same output to confirm if the issue is with the pedal or the output channel.
• Excessive Noise/Hum:
  • While the unit has noise reduction, ensure all cables (audio and power) are in good condition and properly connected.
  • Avoid running audio cables parallel to power cables to minimize interference.
  • Test pedals individually to identify if a specific pedal is introducing noise.
• USB Device Not Charging:
  • Ensure the USB cable is securely connected to both the M-VAVE SK2 and the device.
  • Verify the USB device requires 5V 1A or less for charging.

9. Maintenance

• Cleaning: Use a soft, dry cloth to clean the unit. Do not use liquid cleaners or solvents.
• Storage: Store the unit in a dry place away from direct sunlight and extreme temperatures when not in use.
• Handling: Avoid dropping the unit or subjecting it to strong impacts.
