Product Information
Full details
The Electro-Harmonix MOP-D10 is designed for guitarists and bassists who need reliable, noise-free power for their pedalboards. Its key benefit is providing ten isolated 9VDC outputs with varying current capabilities, ensuring a clean signal path free from unwanted noise. A potential caveat for some users might be its fixed 9VDC output, lacking higher voltage options.

FAQs
Can I power pedals that require more than 9V?
No, the Electro-Harmonix MOP-D10 is designed exclusively for 9VDC pedals. It does not have outputs for higher voltages like 12V or 18V.
What is the current limit for each output?
The MOP-D10 has four types of outputs: four at 100mA, two at 250mA, two at 300mA, and two at 400mA.
Are the DC cables included, and what are their specifications?
Yes, the unit comes with 24" long DC cables. Each cable has one straight and one right-angle connector end.
Can I use this power supply outside of North America?
Yes, the MOP-D10 features an AC Voltage Selector Switch, allowing it to be used with a range of voltages commonly found around the world.
What is the difference between isolated and non-isolated power outputs?
Isolated outputs prevent electrical current from flowing between pedals. This significantly reduces noise, hum, and ground loop issues that can occur when multiple pedals share a power source.
What is the physical size of the DC barrel connectors?
The output jacks measure 5.5 mm x 2.1 mm, which is the standard size for most guitar effect pedals.
Does this power supply include a power cord?
Yes, it comes with a 6' detachable AC power cord.
Troubleshooting
A pedal is not receiving power.
Ensure the DC cable is securely connected to both the MOP-D10 output and the pedal's power input. Verify the pedal's power requirements do not exceed the selected output's mA rating. Check the corresponding output fuse if applicable (note: the MOP-D10 does not explicitly mention user-replaceable fuses, so contact support if an internal issue is suspected).
Audible hum or noise is present.
Confirm that all pedals are using the correct polarity (center-negative). Try swapping pedals to different outputs to isolate the source of the noise. Ensure the MOP-D10 itself is not placed directly on top of noisy transformers or power sources.
Unit does not power on.
Check that the detachable AC power cord is fully inserted into the unit and the wall outlet. Ensure the AC input voltage selector is set correctly for your region's power. If the issue persists, contact EHX support.
One or more outputs appear faulty.
Try connecting a different, known-working pedal to the suspect output. If the problem persists, it may indicate an internal issue with that specific output. Use an alternative output if available, and contact EHX support for assistance.
Pros and Cons
Pros
- Provides exceptionally clean and quiet power, significantly reducing hum and buzz.
- Offers a versatile range of current outputs to power various pedal types.
- Isolated outputs prevent cross-talk and interference between pedals.
- Global voltage compatibility makes it suitable for international touring.
- Robust build quality ensures long-term reliability.
- Includes essential accessories like DC cables and mounting hardware.
Cons
- Only provides 9VDC outputs; does not support higher voltage pedals.
- Does not include any AC or 18V outputs.
- Can be bulkier than some compact power solutions.
- Fixed configuration may not suit users needing fewer than 10 outputs.
Setup, Compatibility & Care
Setup:
- Mounting: Use the included hardware to securely attach the MOP-D10 to your pedalboard. Ensure adequate ventilation around the unit.
- Power Connection: Connect the detachable 6' power cord to the MOP-D10 and then to a suitable AC power outlet.
- Pedal Connections: Use the supplied 24" DC cables (with one straight and one right-angle end) to connect your pedals to the isolated outputs. Ensure you match the pedal's power requirement to an appropriate output on the MOP-D10.
Compatibility:
- Voltage: The MOP-D10 outputs 9VDC only.
- Polarity: All outputs are center-negative, which is standard for most 9V pedals. Verify your pedal's polarity; if it requires a positive center, you will need a polarity-reversing adapter cable (not included).
- Connector Size: The output jacks are 5.5 mm x 2.1 mm, the most common size for guitar pedals.
- AC Input Voltage: Select the appropriate AC input voltage using the external switch to match your region's mains power.
Care:
- Keep the unit clean and dry. Use a soft, dry or slightly damp cloth for cleaning; avoid harsh chemicals or solvents.
- Ensure the ventilation slots are not blocked to prevent overheating.
- Periodically check cables and connections for wear or damage.
