Purpose and Compatibility

This ABLEGRID 9V AC-DC adapter is built for the Electro-Harmonix Doctor Q Envelope Filter pedal. It replaces the original power supply with a non-OEM unit that matches the required DC output and barrel tip size. Musicians needing a reliable mains-powered source for this specific effect pedal will find it a direct fit.

Electrical Limits

The adapter accepts a worldwide AC input range of 100 to 240 volts at 50 to 60 Hz, making it suitable for international touring without a voltage converter. It delivers a fixed 9V DC output through a barrel connector. Over-voltage and over-heat protection circuits guard the pedal against mains irregularities. Users must verify the tip polarity and dimensions match the pedal before connecting.

Build and Daily Use

The unit carries CE, FCC and RoHS certifications, confirming compliance with safety and environmental standards. A standard mains cord plugs into the adapter body, which then connects to the pedal via the barrel tip. Keeping the adapter in a ventilated area during extended sessions helps maintain stable operation. The package includes only the adapter itself.

What does the barrel connector cap in practice?

The barrel tip delivers a fixed 9 V DC supply limited by the adapter's internal over-voltage and over-heat protection circuits.
