- Pedal njikọ: The Iso-Brick features 10 fully isolated outputs, each with specific voltage na ọkwa dị ugbu a.
- Two 9V outputs at 100mA
- Two 9V outputs at 300mA
- Two 9V outputs at 450mA
- Two 18V outputs at 250mA
- Two variable outputs adjustable from 6V to 15V at 250mA
Use the appropriate patch cables (three 6-inch MXR patch cables are included) to connect your pedals to the corresponding output jacks. Ensure that the voltage and current requirements of your pedals match the output specifications to prevent damage.

Ntuziaka ọrụ
The MXR Iso-Brick is designed for straightforward operation. Once connected to power and your pedals, it provides stable and noise-free power. The individual indicator LEDs next to each output jack confirm power delivery to the connected pedal.
Mgbanwe Voltage pụta
The two variable outputs (adjustable from 6V to 15V at 250mA) offer unique tonal possibilities. By adjusting the voltage, you can emulate the "voltage sag" effect of a drained battery, which is often sought after by musicians for vintage-style fuzz and overdrive tones. Use the small rotary knobs next to these outputs to precisely dial in the desired voltage.

Nchọpụta nsogbu
If you encounter issues with your MXR Iso-Brick Power Supply, consider the following common troubleshooting steps:
- Enweghị ọkụ egosi ike:
- Ensure the 18V power adapter is securely plugged into both the Iso-Brick and a working power outlet.
- Nyochaa na ntinye ọkụ na-arụ ọrụ.
- Pedal Not Receiving Power:
- Check that the patch cable is firmly connected to both the Iso-Brick output and the pedal's power input.
- Confirm that the pedal's voltage and current requirements match the specific output used on the Iso-Brick.
- Try a different output on the Iso-Brick or a different patch cable to isolate the issue.
- Mkpọtụ/Mkpu Oke:
- While the Iso-Brick is designed to eliminate ground loop noise, ensure all other components in your signal chain (pedals, amplifier, cables) are functioning correctly and are not introducing noise.
