Overview:
The fuse on a dbx ZonePro should be replaced if the unit does not power on while connected to a confirmed working power source. When replacing the fuse, it is critical to use the exact same type and rating—T 4A, 250V (high‑breaking capacity)—to prevent damage to the unit or potential safety hazards.
Instructions:
- Unplug the power cord from the wall outlet and the unit.
- Locate the Fuse Holder under the IEC power connector on the back of the unit.
- Use a small flat-head screwdriver to gently pry the drawer open.
NOTE:
A replacement fuse is located in a compartment on the fuse holder.
- Remove the old fuse and insert a new replacement.
Fuse specifications: T 4A, H 250V.
- Push the drawer back into the unit until it snaps into place.
NOTE:
If the fuse blows again, this indicates a potential fault in the power supply, and will require evaluation from an Authorized Service Center.
