Question about JBL SCS135 System

1 Answer

Subwoofer isn't working

When the subwoofer has been powered on for a few minutes it makes a very loud popping noise every few seconds. Suspecting damage to the wire, I switched it out for a different one and have the same results. Prior to this happening, it made a very deep, low hum if it was left powered on and the receiver wasn't. Perhaps that was normal.

Re: subwoofer isn't working

If your wire connections are normal then the problem is due your woofer speaker. Its your subwoofer circuit error and must be repair thru replacing the damaged Component in the circuit

Klh powered subwoofer model ASW10-120B... when you plug in to power... it makes a loud buzzing/humming noise

I would check the caps on the power supply. They are rather large electrolytic capacitors that will look like they burst and/or leaking. When these die, the caps ground and the sub will make a loud buzzing sound. If you are handy with a soldering iron you can replace them yourself. Replace them with the same voltage or a little bigger and same with the size.

If the cap. says 16v 4700pF on it, for example, a 20v 5300pF or a 16v 6200mF cap. will work for this application.

JBL PB12 will have loud thump or pop!

First try to find the source of your problem. The easiest way would be to try your sub with a different audio source to see if the problem still occurs but is sounds more like there's a problem with the receiver.

S8 makes a very loud vibrating buzzing noise with only the power lead plugged in

Check for ground loops. Also shut off any CFL or LED lamps inthe vicinity.

You may also have an intermittent connection on the input.

There is a lesser chance that there is an internal failure of a capacitor on the amp power supply, but it is a possibility to look at if all the wiring is in place and soundly connected. The S8 has a high gain amp. It will pick up interference from CCFL or LED ballasting supplies it will also be able to pick up other switch mode power supplies. in vicinity of the input cable.

My subwoofer keeps poping and then stops working

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.

I get a loud static noise, when I first turn on the yamaha ysp-1. Lasts a few seconds. Have unplugged all inputs. Problem persists.

u have a cool sound projector but u have a baaaad power supply system. bad power supply design - u will get all sorts of noise when u power it up. i have a sub woofer with the same problem(which in my case is the way it is designed). i used a delay circuit. but in ur case i know YSP-1 has a clean start up. so, if the warranty still covers it get it replaced. static noises, pop noises are often caused by bad capacitors.

Sunfire annoying popping noises

If you remove the volume knob, and tighten the nut below, it should take care of the popping noise, as well as any input noise issues. Based on my experiences with my MKII

My JBL PowerBass PB12 makes a continued loud sound when it is on

Have you tried turning the gain down before turning it on. If that works, it might be the internal amp picking up noise somewhere. Maybe even a bad ground. Either way there are only a few things you can try before complaining to the manufacturer or replacing it. Changing its location might help and if it does might indicate RF interference. You can also try running it through a power strip, one equipped with a filter (these are fairly common). Good luck

Cerwin Vega ve-28s subwoofer and new Cervin Vega 2-way satellites

I bought my VE-28s and it did exactly that crackled, cerwin replaced part in amp but few months later problem persisted. they then replaced entire amp assembly and its been fine. i really push it to and its been fine. to test it, unplug the connection from amp/ reciever and see if it persists. if so its the sub, if not its the amp/ reciever. dont dump it, these subs really crank and can put out some deep loud bass.
