This may be a power supply or a faulty capacitor that is worn and out of range. It can be tested with an ohmmeter. Most bad caps are swollen, leaking, or have burn marks on the circuit board.

Get the user's manual for hookup instructions. Don't bridge anything that you are not sure of. If you are referring to the speakers connections, they are used only if you do not have a sub out from the receiver.

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.

what is wrong with it ? is it the sub ? the sub surrounds ? the amp ?

more info please :)

maybe the cable you use to connect the subwoofer to the receiver is bad.
does it work better for music?

The problem is in the amplifier section.

This sub uses the same amp the HGS units have. The pre-amp is a lot like the HGS units as well.

The only place you will find to service the unit will be Velodyne.

My guess is that you will need to send the amp section to them.
It is easy to remove, just make sure to mark the speaker leads before you remove them.

For the auto on function.

You may have a low signal to the sub.

If your source has adjustments for the sub output, try setting it up a number or two. Then use the volume control on the subs amp to mach your main speaker volume.

The volume control pot can be replaced.

Any good quality audio shop or electronics repair shop should be able to fix this.

May be a dead amp.

Only place for service is Velodyne.

If my memory serves me on this amp, the volume control is actually a chip in the pre-amp section.

You could try and replace the actual knob on the panel and see if that fixes the problem.
If not, you will most likely have to send the amp section back to Velodyne for repair.

If you do send the amp back, use some masking tape and mark the speaker leads. Hooking these back up wrong will blow the driver and the amp.

Sounds like an amplifier problem.

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. https://velodyneacoustics.com/pdf/vx-11/VX-11Manual.pdf

It sounds like you may have ripped the passive (the rubber material around the speaker that stretches when the speaker hits. If the passive is not ripped then it may be picking up static, or it could be blown. You can purchase a noise filter fairly cheap and try that.
