Top 20 Velodyne CT-80 Subwoofer Questions & Answers

has it ever worked, if so did you ever use it in the cold because in the cold it is possible for the wiring inside the speaker to crack and break

larryagross,
Sounds like you blew the speaker! The amp is sensing the voice coil is connecting to the speakers magnet or iron core and is going into a safe mode. It is possible to blow the coil even when the sub has a built in amp.

First make sure that you have the gains properly set ans not all set to their maximums. Second, disconnect signal to the sub then unplug the power for a few minutes. Third, plug the sub into a source of power on a different circuit using a surge protector.

Does the speaker make any popping at the time it powers up? If so you have a amp problem. If there is no sound produced, connect it back the the system using a different signal cable. Does the speaker now pop again when sound is produced. If so the speaker has failed. Contact a Velodyne repair facility.

One of two things may be going on.

The amp has a fuse mounted on the PC board. The fuse may be blown.

The speaker may be bad. that may have blown the fuse.

You can test the speaker with a "D" battery.
Take the amp section out of the back, disconnect the speaker leads.
Touch the speaker leads to the poles of the battery. it should make a little thump and the cone should move freely.

Contact Velodyne for service.

Have you selected the appropriate input type? (e.g. Optical, HDMI?)

Some receivers (like my Onkyo 606) support HDMI passthrough, but will not decode audio signals from HDMI. Making it a pretty useless port!

Do you get sound when you select FM Tuner on the Pioneer?

The Q55 is not a velodyne product

cheak setting in sterio out put for sub on ect does woofer have sperk wire going in and out use them then ok

Not about Velo subs

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.

Request schematic from manufacturer

You need to remove 12 outer screws, then remove the amp it might be held in with gasket.

There is a repair shop Edwards Electronics they are master's at repair. They are on web and eBay.

Sounds like you will need a new amp. Please send your serial number and the complete model number if it is different and I will quote a repair. [email protected]

Replace all the greatest sized capacitors inside are deformed or leaking. can be a 6 pieces because some of them are used parrallell to get double capacity.

The loud humming could be caused by a cable on the input that is not grounded. It could also be caused by some sort of power supply failure. If you need further help, I’m available over the phone at https://www.6ya.com/expert/david_29ad5d1dd86564b0

I'd contact Velodyne directly. Check their website, velodyne.com/contacts/

It could hurt the speakers and the amp, depends on level of internal protection they were made with.

If your subwoofer has a line level input (RCA-style plug), see page 24 of this link: http://www.audioproducts.com.au/downloadcenter/products/Denon/AVRX2000BK/Manuals/AVRX2000E2_ENG_CD-ROM_IM_v00.pdfRun a cable from that to the line level input on the subwoofer. If I understood you correctly, here's a link to the owner's manual: http://velodyne.com/vx-11.html

possible shorted capacitor in the amplifier stage

no it will draw too many MA through the circuit than is allowed

You did not state what model this is.

If it is a servo controled unit, you may have a problem in the control circuit.

The models that use the servo control stystems should only be serviced by Velodyne or one of the listed service centers.

Velodyne is the only source for parts for these units.
