Velodyne F-1800 RII Subwoofer Fuse

Already answered for DPS-12 in 2011 which suggests a fuse where the power enters, However, your manual mentions no fuse, but 'protection circuitry'. If there is a fuse, it will be inside and on a circuit board. All fuses have the rating on the end cap of glass fuses and on the side of ceramic fuses, which as also colour coded.

Sep. 11, 2011 - where to find fuse on velodyne vx-10b - Velodyne VX-10 Subwoofer. ... in the manual shows a fuse rating of 2 amps where the power cord enters the box. ... here's a link to the owner's manual: http://velodyne.com/vx-11.html.

Just a guess, but the drawing in the manual shows a fuse rating of 2 amps where the power cord enters the box. Is this a combination fuse/connector. Have you looked if the rocker switch accommodates a fuse? Sorry if no help.

I have a suggestion that you can try. If the unit is no longer turning on and you're sure the electrical outlet is good (by plugging in another device) and the hand-held control panel is on, as well as the switch at the base of the subwoofer, then try replacing the fuse. The subwoofer on this model has a fuse near where the power cord enters the subwoofer. There is a slotted screwdriver slot on the fuse cover. Using a flat-head screwdriver (or your thumbnail), turn the cover about a 1/4 to a 1/2 a turn and the fuse should pop out. Keep the cover. Replace the fuse with a 4 amp, 125V (or higher) fuse that is a slow-blow fuse. There are fast blow (or fast acting) and slow blow (or slow acting) fuses. You can't replace one for the other. You should be able to find a fuse at Radio Shack. If a new fuse doesn't get your system working again, then something else is broken. Good luck.

Most powered devices have a fuse. Does it work after being turned down in volume? or is it completely dead with no signs of power? or does it show some indicator light but no sound? Check for blown fuse and then for blown speaker coil.

The amp is blown. You need to get it in for service. No telling exactlly what is wrong untill it is opened. 215-736-8055

Check for blown fuse?

May be more than just fuse.

If Velodyne wants the whole unit shipped, that is what you may need to do.

then the circuits took a hit and the fuse didn't do it's job in the 1st place. best is too get new circuit thats inside the sub woofer.

sorry to be the bearer of bad news

Fuse in amp may be blown or the amp is dead
