Question about Velodyne VRP-1000 Subwoofer

Open Question

Hi, My son needs help with a VRP-10 velodyne subwoofer. It doesn't work. We did a basic check of the transfformer and there was no power coming out. Unless we're missing something, we suspect the transformer is bad. Are we correct with our diagnosis or are there other defective parts that may cause to transformer to stop working? Thanks

SOURCE: Major buzz/Humming sound coming from my subwoofer

Well there are only a few reasons i can think of that just might be the reason behind said buzzing.

1. It may be connected to another power source ( amplified or powered supply ) or incorrectly connected. It may also be too close to said power supply.Try letting the dog (sub) out on his leash a little Drag out the manual that came with the sub, and check the correct procedure for your type of setup.
**People do read manuals still don't they ?**

2.The only other problem i have heard of is port noise in low registers. Keep the the port area clean, as it may suck up dirt, or even worse, small children!

3. However, if you're considering placing this subwoofer in a cabinet, I'd recommend allowing ample breathing room for the heat sink. This can also be done by drilling smaller holes in the cabinet ( 8-12 mm holes - with the owners permission of course) but please do remember to keep the port area clean.

4. The product ie: Velodyne DPS-12 Subwoofer, came with a bad power supply, presuming it is new, check your warranty.
(not very likely - see also scenarios 1, 2 or 3.)

Velodyne has been making subs forever and do it well.

SOURCE: how to connect pioneer reviever to velodyne subwoofer

Look for the sub pre out on the back of your amp and connect a sub cable to this and next to the LFE or phono type input on the back of the sub ,if it has two inputs left and right pick the left side ,set the cross over to suit your system and speakers,if you are not sure set the cross over to 80 hertz,this is a thx standard.
hope this helps.

SOURCE: No sound for Velodyne ct-100 sub woofer

Sounds like a dead amp. You could check the xformer output and the amp IC's with a VOM.

These amps do not cost a lot, about $40.00. and are easy to replace.

Contact Velodyne

I hear noises when DD-10 is turned on.. even without signal to i


If it is a low level white noise, you may have some form of RF noise that is being picked up by the driver mounted servo system.

Then it could be something else as well.

Best to contact Velodyne to see about service for your unit.

Right side audio valume not working


Do you mean that the right speaker which is routed through the subwoofer's Speaker Level In and Out is not working? Did it all start when you added the subwoofer?

Perform some isolation and connect that speaker directly to your receiver to see if it works.

YES? Recheck the speaker connections. After all, the sub is only connecting your receiver to the speakers after borrowing LFE information. Observe matching + and - polarity throughout.

NO? Either the speaker or the Receiver channel have a problem, but that isn't likely if the problem appeared just from putting the subwoofer into the mix. You can swap speakers to eliminate them and swap source amplifier channels to isolate them.

Woofer,s outer ring is ripped.


To fix this problem, you will need to contact Velodyne.
They may be able to replace the surround or recone this driver.

Because this system has the "servo" control, you need to have the accelerometer conected to the amplifier. With out it, the amplifier will not operate.

Velodyne is known for good service, i think in this case it is best to contact your vendor and have it solved.
