Quick guide from the manual

The D'Addario XPND Pedal Power Battery Kit is designed to provide clean 9V power to guitar effects pedals. This guide covers the two primary power methods: using the portable battery or a USB power supply. It also details how to charge the battery and provides critical safety information regarding pedal polarity and power limits.

Powering with Battery

To power your pedalboard using the portable battery:

Connect the portable power supply to the Power Gateway using the included short USB-C cable (275mm).
Connect your pedals to the Power Gateway using the adjustable daisy chain.
Press and hold the power button on the battery to turn it on or off.
When the battery is on, it will display the current charge level.

Powering with USB Power Supply

To power your pedalboard using a USB power supply:

Connect your USB charger to the Power Gateway using the long USB-C cable (2m).
Connect your pedals to the Power Gateway using the adjustable daisy chain.
Ensure you are using a reliable USB power source.

Charging the Battery

To charge the portable power supply:

Connect the USB charger to the portable power supply using the USB-C cable (2m).
The battery will display the charge level during the process.
Only use the included D'Addario USB battery or USB charger to power your XPND Gateway to ensure clean 9V power and proper function.

Noise Isolation

Certain combinations of pedals, particularly when mixing analog and digital pedals, can cause noise issues. The Pedal Noise Isolator (PW-XPNDPNI-01, sold separately) can be inserted into the daisy chain to silence a noisy pedal by providing true galvanic isolation.

Safety and Polarity

Warning: Polarity is critical. Always match the color code on the wire and plug body to ensure proper connections.

Standard Polarity: For most effects pedals, the center pin (tip) is negative (ground) and the outer barrel (sleeve) is positive (hot).
Power Limit: Do not exceed 1500mA total power draw.
Damage Prevention: Connecting a tip-positive power supply to your system could cause permanent damage to your effects pedals.
Usage: Intended for indoor use only. Do not use near water, liquids, or heat sources.
Maintenance: The adapter and battery are not serviceable. Do not attempt to open the adapter or battery.

Practical help

Common problems

Audible noise or hum in the signal chain

Use the Pedal Noise Isolator (PW-XPNDPNI-01) to provide galvanic isolation, especially when mixing analog and digital pedals.

Pedal not powering on or potential damage

Verify that your pedals use center-negative polarity. Connecting a tip-positive power supply can cause permanent damage.

Powering off unexpectedly

Ensure the total power draw of all connected pedals does not exceed 1500mA.

Before use

Verify that your pedals require center-negative polarity (center pin negative, outer barrel positive).
Calculate the total power draw of your pedals to ensure it does not exceed 1500mA.
Use only the included D'Addario USB battery or USB charger for guaranteed clean 9V power.
Check all cable connections before powering on the unit.
Keep the unit away from water, liquids, and heat sources.

Specs in practice

Center negative: The standard polarity where the center pin is ground and the outer barrel is positive.

Model compatibility

Only D'Addario circuitry is guaranteed to provide clean 9V power and proper function.
The Pedal Noise Isolator (PW-XPNDPNI-01) is sold separately.
