The brown resin is glue that changed color due to heat and age. Rarely have I seen it cause problems. So unless you are having problems, No.

Go to the Velodyne web site, look under the support section and check the service center listings.

Also you could try the place you purchased the unit.

If you have changed the signal source, then these may not be the problem at all, it may be that you have the sub output set to low on your processor.


This may be one of these problems.

It could be the "auto on" circuit.
If you change the switch on the back of the unit to always on does it still do this? if not then it is the auto on circuit that is the problem.

The driver mounted servo unit is starting to fail.

A cap in the amplifier input section may be going bad.

You nwill need to contact Velodyne for repair of the unit.

Fit a 3 or 2.5 anything lower, if you can get away with it, but nothing higher.
However the chances are that it blew due to an overload, often caused by a shorted semi-conductor acting like it was a piece of wire. So even fitting a smaller one and it blowing again doesn't mean it's due to the rating.

I wish to replace a subwoofer on a surround sound system


In most surround sound systems the sub woofer is powered separately and uses a standard RCA coax connection to the receiver/amplifier.

Replacing is simply plugging in the new and reconnecting the coax cable.

Usually the audio signal is Dolby Digital 5.1 the (.1) is the LFE Sub-woofer. The connection is between the Subwoofer RCA connector on the amplifier and connects to the (LFE-Line) in on the subwoofer speaker.

Hope this helps?

ProSub 600 tripping off during playback of low bass and turns on after a while but works perfectly if volume is turned down. what could be the problem?



  • The DSW ProSub is a nice amplified sub. The reason it is shutting down is the amp is being worked to hard and it's going into thermal mode and after you turn down the volume and it cools down it's coming back on. To much of this and you will have a nice sub and no amp to run it.
  1. One thing to do is keep the sub/amp in a well ventilated are and put a fan on it if you can to help move the heat away from the unit.
  2. The amp is rated at 250 watts so if you push it to hard it's gonna keep shutting down. So turn it down a little so it runs longer and smoother or add another sub to the set up if you need it louder (like we all like). One sub can only do so much.
  3. Also make sure if the receiver your using has a base setting or an EQ that you keep them levels set a little lower. Most receivers and home theaters already have an amp in them and you don't want to run to much of that into another amp. It's over kill. Find that happy medium.

Conncet a sony sub to a denon reciver


Depending on the model, there are two ways to connect a subwoofer to an amplifier, receiver or processor. The best way is to connect the subwoofer to the SUB OUT or LFE output of a receiver, but some subwoofers can be connected to the speaker level outputs of the receiver or amplifier.


1. How to Connect a Subwoofer to the Subwoofer Output


The preferred method of connecting a subwoofer is through the LFE or Subwoofer output (SUB OUT) of a receiver. Almost all home theater receivers (or processors) and some stereo receivers have a subwoofer output. The LFE (Low Frequency Effects) is a special output for subwoofers and is often labeled 'SUBWOOFER' not LFE. 5.1 channel programs on DVD discs have a dedicated .1 channel output with bass-only content that is best reproduced by a subwoofer. Connect the output of the LFE or Subwoofer jack to the Line In jacks of the subwoofer using a single RCA cable (the two jacks on the left in the photo). A 'Y-Cable' may be necessary to connect the LFE output to both the left and right channels of the subwoofer.

2. How to Connect a Subwoofer to Speaker Level Outputs
Some receivers and amplifiers do not have an LFE or Subwoofer output. In this case you can use the speaker outputs of the receiver to connect the subwoofer. Using speaker wire, connect the left and right channel speaker outputs of the receiver to the left and right channel speaker level inputs on the subwoofer (the speaker inputs on the right side of the photo). Using speaker wire, connect the left and right channel speaker outputs on the back of the subwoofer to the left and right channel front speakers.

Hope it helped..

Can I connect my floorstanders to wharfedale sw150 without any external amplifier, If so, how ?


What 'floorstanders'?

Its internal amp is for its own subwoofer ONLY, but if you use your own amp's full-range speaker-level outputs to feed two chanels entering the sub you can tag the 'floorstanders' onto the sub's speaker terminals as speaker wire extenders. Your amp will be powering the floor units.

I'd keep the sub separate and feed it LFE only if it was mine.

Difinitive prosub 600 keeps turning its self off??? I have connected the sub every which way, low level RCA to sub out, using the prosub 600 as a bus for the front monitors, even both together. I have...


"Somthing seems to be wrong with the automatic on/off???" That's my guess too. Your sub requires a certain signal level to turn on, probably because of a sub-sonic filter. I just changed to another sub that did not have that "feature". Problem solved.

Please Help ....i have Bose Acoustimass 10, 5.1 system connected


Usually the LFE out is only a line out and is not amplified in any way, so first of all is your subwoofer self amplified or not? Cause if not, the LFE output won't be of much use to you. So if it's not self amplified you need an new amplifier to put between the receiver and the subwoofer. Any amp that supports RCA line-in input will do. Even a car stereo amplifier will work provided you can get a 12volt power supply to run it in the house. If the subwoofer is self amplified though, then all you need is to make an adapter cause none are readily available in stores to go from a RCA connector to 2 wires. You can buy a virgin RCA connector that you can wire yourself at The Source, Circuit City, or any electronics store you have locally, or if you have an old RCA to RCA wire you don't need anymore, you can just cut it in half, strip the 2 wires and you got you adapter right there.

What eq settings do i need


Hello ed4037, If you are blowing fuses this means that you are drawing too much current check your impedance value on your amplifier it should be 8 ohms to match the subwoofer's 8 ohms of impedance. In addition make sure that you have the proper value fuses. In other words you should not be tuning the amp not to blow fuses, because you should be able to go to full amplitude on your amp without blowing anything. As I alluded to this sounds like an impedance mismatch problem. I hope this helps, Thank you, Shuttle83
