Subwoofer thumping when changing channels

When I use any of the digital audio inputs on my receiver it is causing a thumping noise from the sub woofer. Example 1: When the dish reciever is connected with the optical cable I'm getting the noise whenever I change channels. Example 2: When the DVD is connected with the coaxil cable the noise occurs whenever I start/stop/pause or select anything from the DVD menu. Example 3: The noise is also caused by changing the input selections on the reciever.

None of these problems occur when components are connected with regular audio cables.

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?

Home Theater sub not Thumping

An often overlooked issue with quiet or no sub woofer output is that if the front and/or mid are set as Lrg or Med there is no SubWoofer signal or it is drastically decreased. So check your speaker size settings (Generally found in the setup of the receiver and you may be pleasantly surprised by the return of the missing thump. Your neighbors? Not so much ;)

The subwoofer starts to make a loud thumping sound

Remove the signal source and power it on to see if the problem occurs without any input signal. The problem could be in the receiver and not the sub

You have a very good of the best of SONY..SUB does not get activated automatically especially on STEREO mode.DIRECT STEREO Notes • No sound will be output from the subwoofer.
.your system has Dedicated Power Amplifier for 2 Externally Driven Sub-Woofers (200W RMS x 2) order to activate the sub woofer amplifier you need to make a selection on the surround modes while you are switching the modes of the surround you will see the speaker position on the display of receiver as well..if you do not see the sub woofer it wont be activated..Sound Field Program (A.F.D) is a good example to test it..

• Select BOTH if you connect a subwoofer and you want
to output low-frequency signals from front channels to

I have a jvc seteup but reciever is there a way i can get a adapter to plug sub woofer with power amp into a a yamaha reciever?the plug that goes from sub woofer also powers other speakers, cable...

Here's a manual.

That cable not only carries audio but it also powers the sub and other channel amplifers. Even if we could supply the pin-outs for the channels I'm not sure what we could do to provide subwoofer power. We're talking about a major rework.

This is a highly proprietary design, meaning it's really not very adaptable to normal spec audio equipment.

There's a flat-fee repair service for the receiver ($99.95, free return shipping):

Maybe they could fix your receiver.

You COULD try to reach the manufacturer for other options.

How do I use my Bose Subwoofer with a different receiver??

You can use Bose Sub woofer with any receiver. There is a set of "Audio Input" jacks on the back of the Bose. Connect the plugs on the one end of the audio cables to the "Audio Input" jacks on the back of the Bose.
Connect the plugs on the other end of the audio cable to an "Audio Out" jack on the receiver.
If the "Audio Out" jacks do not match with the plugs of the audio cable, then you need to use adapter or modify the audio cable.
In case "Audio Out" jacks are not provided on the receiver, you may take the audio output from headphone socket.
hope this will help you.

Just got JVC SP-PWC50 subwoofer and 2 SP-THC60F front speakers but thats all!!! How can I hook up and power up? What kind of mids and rears can I hook to this system? I have several old Sony and Harmon...

Your intended project sounds interesting. I like the idea of retasking older audio gear into modern multichannel sets. One good reason to use older equipment is that the specs, interfaces and interoperability are standardized so you can tell if/how a given amp and speaker will work together. I do it myself.

It looks to me like you have only part of an HTIB (Home Theater In a Box) system that uses a proprietary 8-pin connector and system cord that would come from the base unit/DVD/receiver (the 'brains', which you don't have). It doesn't appear to be designed for compatibility with other units, say, something that would bring in the 5.1 channel audio via either a digital (SPDIF) cable or via 5 separate RCA audio cables.

This subwoofer is self-powered and also provides amplification to up to 5 other speakers, two of which you have.

Their connection to the sub would be via standard speaker cables, likely the Red and White FRONT spring clips. The output terminals are rated up to 16 ohms so attaching a foreign speaker should not be a problem other than its having unpredictable frequency response.

Besides basic connection and signal processing, the missing DVD/Receiver would also decode and direct the 5.1 channels to the Sub and handle level matching of the channels. Without the 'brains' of the system you'll have to get creative to use the individual parts. The 8-pin input connection will be a big problem unless you're adept at getting inside the unit to figure out where things go before they come out at the speaker terminals. Then you'd have to do some rewiring.

UNDERSTAND THIS: Those connectors are OUTPUTS to speakers, not inputs from an Amplifier. If you hook that up wrong you better have a fire extinguisher handy. Kidding. But it could be bad.

The Front speakers are 3 ohm impedance, clearly designed to be used with the amps inside the Sub so I would be careful in trying to drive them with amps that aren't good at handling low impedances. Give it a try AFTER checking the low impedance tolerance of your amplifiers, but easy on the volume.

I would not expect all of this to be a worthwhile effort unless you just like the challenge. Even if you succeed in making a satisfactory electrical connection with your multichannel source as input there is no way to know if it will sound okay. With all-in-one systems the manufacturer may have matched the speakers up with special amplifiers that are designed for 3-ohm speakers and to shape the sound through active internal equalization in such a way as to produce flat response from non-flat-responding speakers - like Bose does, for example, but at least they tell you that's the case.

The stated spec is 200 watts (RMS) per channel at 3 ohms at 100Hz with 10% Total Harmonic Distortion, a very unusable spec. True and honest watts/channel specs look like, "XX CONTINUOUS watts per channel, all channels driven into 8 ohms (20 Hz - 20 kHz, +0.5 dB, -3 dB less than 0.5 percent THD)".

At only 27 lbs with a Power Consumption of only 160 Watts I'd say the Amps/Sub component of the package is a lightweight, literally and figuratively. Apples and oranges when compared to grown-up audio components. It might get loud but not cleanly. But that's just my opinion.

Here's the Owner's Manual for the entire kit...

There's some discussion of the features, etc, here...

Kenwood vrs-6100 receivers optical digital

You want to receive the optical signal from the TV's built in decoder / receiver to play through your Kenwood? Maybe you need to select the digital input. The manual says:

Use the INPUT SELECTOR key (or Input Selector keys)
to select DVD, VIDEO or FRONT AUX.

2 Press the INPUT MODE key.
Each press switches the setting as follows:

1 "F-AUTO": Auto detect
("AUTO DETECT" indicator lights up)

2 "D-MANUAL": Fixed to digital input
("DIGITAL" indicator lights up)

3 "ANALOG": Fixed to analog input *
("AUTO DETECT", "DIGITAL" indicator goes off)

Also check your TV to make sure it is outputting to the optical jack.
