Radio Coming Through Speakers In Home

1

i will think of those audio device are hooked as much as a stereo device. Interference is in many cases a close-by transmitting station. Describe what you hear. this might help. Does it happen regardless of what radio station you're tuned to? hear to the stereo by headphones. See in case you hear the interfering sign there. If no longer, the speaker cord is probably appearing like an antenna and determining on up the sign. The cord is probably 2 cord zip twine (style of like means twine for a lamp). if so, commence with a rapid restoration rerouting the twine faraway from living house windows, different electric powered contraptions, different wiring and ungrounded steel gadgets if achievable, very authentic in case you have the cord looped or coiled in places. if this is the zip twine it is the criminal, your are turning out to be direct detection radio frequency (RF) interference. circulate to Radio Shack and get 2 one hundred picofarad (pF) ceramic disk capacitors (they...

I have a HP Pavillion DV6 earlier and today an Insyde Flash window popped up, I didn't know what it was and didn't trust it so I closed it, a few seconds later a CMD window opened and closed then the sound on the video I was watching starting stutering and stopped so I went on another video and the same thing happened and there was no sound on spotify so I rebooted. When I turned my laptop it was all normal so I went back on spotify and noticed a message at the top that says "There is a problem with your sound card. Spotify can't play music." and still no other windows will produce any sounds, I then realized I can get sound on things like youtube or games through my earphones, except spotify won't play any music and still produced the same message, I'm currently doing a system scan and updating 11 things that were waiting for me, none of which seemed to have been from Insyde. I'm really stuck with this and hoping someone here will help me...

The probability is that the gain stage in the amplifier/speaker setup is so high that you are lifting the normally unnoticeable background noise inherent in the computer's sound card to annoying levels.

The simplest solution is to turn up the sound card to full volume, then adjust the amp's volume down, that will take the background noise down with it.
The amp/speakers are probably more than capable of handling the computer's output at full volume - but if you start to hear any distortion, just back off the computer's volume a little & compensate on the amp.

To eliminate the background noise altogether, you would probably need a dedicated sound card; external over USB would provide the best isolation from the computer's...

How you set up a microphone to play through your audio receiver's speakers depends on the kind of equipment you have or are willing to buy or rent. Most receivers are capable of directly connecting to microphones, but this often doesn't produce optimal performance. Typically, you need some extra equipment to get the best performance from your microphone and receiver.

Video of the Day

Most audio and AV receivers feature a dedicated microphone jack, often marked Line-In, Mic or AUX. The simplest and usually least expensive option is to directly connect your microphone to this jack and switch to its input channel. However, with most microphones you'll find that there is a significant drop in volume compared to your other devices.

The reason for this drop in volume is that microphone lines carry audio at a substantially lower decibel level than other audio devices. Since the microphone can't supply the same level of volume to the receiver, a direct connection...

This is not an uncommon problem.

I suspect the cable from receiver to TV is quite long. This cable is acting as an antenna to the radio station, and being detected and rectified by the first IC voltage amplifier chip. All solid state junctions have the potential to act like the detecting diode of an olf fashioned crystal set.

You have a few options.

Can you in any way shorten the distance between TV and receiver?

You could solder small RF chokes inside a male stereo TRS jack, and then plug that into a female TRS in line jack and connect each end of the TRS plug and socket to RCA jacks. Place the TRS jack with the RF chokes as close to the receiver as possible.

Use an unbalanced to balanced transformer at the TV, and change the cable to a balanced 600 ohm one, and then use a balanced to unbalanced transformer at the receiver end.

Options two or three would guarantee the best success.

Let us know which you would like to do and I will try and...

This is SO strange, started happening a couple days ago. I have AVG, winpatrol, zonealarm, and spybot. Everything is saying that my system is clear, no viruses. I can run hijack this if someone would want me to, however maybe someone's heard of this and can tell me what it is.

I have NOTHING running except tskmgr. I just rebooted my system, I had taskmanager up to try to find out why my performance is peaking so much, seems like my system resources are really being taxed (I know when my computer "fan" or whatever is making noise down there comes on. It normally happens when I have lots of windows open that I'm simultaneously working in. I can understand that. But when no windows are open and nothing is running?) The performance should be next to nothing...so just when I am looking in task manager to see what is running if anything, and wondering why my performance is so high, I hear a radio program coming through my speakers. I don't have any Cd in my drive, I haven't turned...

It's called RFI, Radio Frequency Interference.

Certain capacitors in the amp, or on the motherboard can act as radio tuners, as can unshielded speaker wire. Your only hope is to use shielded speaker cables, ensuring that the shield is grounded, and make sure you have three prong (grounded) outlets. Sometimes rerouting your wires behind the PC can help.

Do you have dial-up service/modem. If so the telephone wire is susceptible to RFI in a big way. The RFI can bleed into the PC and cause your situation.

Try reading this artile and see if there is something that can help you in it...

How to Make TV Sound Come Through Your RV's TV Speakers

When playing the radio in the RV, the sound coming out of the speakers in the back bedroom is very soft. How do I adjust the volume of these speakers? There must be a control somewhere.
And is it possible to make the TV audio go through the RV speakers?

It's a 97 Pace Arrow that I recently bought.
Thanks so much!

ANSWER Hi Dana. first let's talk about getting your RV’s TV sound to come through the speakers on your radio and then we will work on fixing the speakers in the rear of your RV. There are two ways you can get the TV sound to come out of your RV's radio speakers. You first have to determine if your radio has an auxiliary input on it.

Look at the front of your radio and you should see source buttons marked "AM" "FM" and "CD" (if your radio has a CD player in it). You are looking for a source button marked...

Thanks everyone, it is appreciated. I am going to try pulling the system apart and see what I can come up with for a solution, following some of the suggestions here.

A few additional details. This got markedly worse with the addition of a new modem to the system. It was there with the old modem, but about 5% of what is there now. That modem was failing and would not keep connected and needed replaced and the model is no longer available.

The "noise" (crosstalk?) gets worse the more data is coming down the line. If I am doing nothing online, it is minimal, surf it gets worse, stream live tv and it is pretty damn awful.

The entire audio chain is powered from dedicated sockets that have their own dedicated line from the fuse box.

The entire PC chain is powered from a Belkin UPS plugged into a different line from the box.

The only connection between the two parts of the system is the line out from the sound card to the pre-amp.

I have disconnected...

Hi, I'm not very technical, so I don't know if this is going to matter... But here's all the info. I have on this culprit... I'm not sure if it'll be the same consistent numbering as on my computer, though... This is what I wrote down from my experiences:

*I went to "C" hardware drive - Then windows- Then installer - then found this number (which was the one that Prevx CSI detected:

*It was a "Trojan agent" ... under this number section on my computer:
C:\windows\installer\e710a26c-b227-4599-824b-8c

We (Geek Squad and I)went into the computer by Safe Mode and deleted everything because it wouldn't allow it in normal mode - kept saying something like:
"RunOnceRom" was being used by another person or program...it didn't block us in Safe Mode, though.

If you understand computers (which I don't much), you can't just delete it from that one numbered area above...We clicked START, then RUN, and typed in: reg.edit

Then we searched for it...

Hi Ali,

I understand you frustration. It could be difficult when things don't work the way it should be on a brand new computer. However; let's try to narrow down to see what is causing this issue and try to fix it.

Please assist me with the following information related to this issue:

What is the make and model of the computer?Does this behavior occurs only while watching videos on Netflix or is it while trying to play any audio/video offline?Have you connected any external speakers to your computer?

This issue could be caused by cables that aren't connected properly, damaged drivers, incompatible drivers, sound settings, missing updates, and problems with your sound card.

Make sure that there is no phones, radio near to your computer as the frequency of these devices could interfere causing disturbance.If you have connected speakers, make sure your speakers are correctly connected to your computer.Many computers have three or more jacks that connect to a...

It's nice to see so many users of logitech on this thread

, i have the same logitech speakers and also recieve radiowaves through them but only when the volume is set to the lowest setting.

it seems that when the speakers are plugged into a device (any device) which has a power supply attached to it, the speakers will receive the broadcasts. if the speakers are plugged into the device which is running on battery power, then no radio is recieved.

I was reading on another forum of a user having the exact same problem and they described that it's a combination of:

1. Changes in the earths ionisphere: at night radio waves are reflected for further distances which is why we can only hear the frequencies at night

2. Speakers are prone for Radio Frequency and Electro Magenetic Interfearence: poor quality speakers and wiring tend not to be sheilded from these so the interference is picked up. Audio systems with higher quality cable and components...

Q: As I am typing this, a random radio broadcast is coming through my monitor's speakers. My computer seems to be somehow capturing a radio signal. What can I do to prevent this?

Q: As I am typing this, a random radio broadcast is coming through my monitor’s speakers. My computer seems to be somehow capturing a radio signal. What can I do to prevent this?

— Cheryl Frizzell, Mercer Island

A: The most likely cause is the wiring that connects your speakers to your computer. Most such wiring is not well-shielded and can pick up radio signals as well as signals from portable phones and other devices.

And, by the way, the longer the wiring to your speakers is, the more prone it is to interference. The wiring essentially acts as an antenna.

What can you do about it? Try simply moving the wiring and the speakers a bit. That may be enough.

If the problem remains, and if you’ve got a lot of unneeded length of wiring...

It probably is not the landlord's fault.

If you are dealing with very strong local radio signals, all you can do is sell or throw away any electronics that are manufactured in unshielded plastic boxes, and only buy high quality electronics in shielded metal boxes from stores where you can easily return items that fail in your environment -- and even then, you may need to take extra steps such as applying ferrite RFI suppression chokes to all input and output wires.

(If you are wondering if you can sue the radio station or ask them to replace your devices, you can't. They have a license to cause this kind of problem, and at least in the USA, the FCC has decided that RFI is typically the product manufacturer's fault and not the radio station's fault).

What you have is a very strong radio signal around devices that aren't designed to reject it.

This problem is called Radio Frequency Interference. In the early days of AM radio, people made crystal radios...

OK, so whoever guessed virus gets the golden ticket! I wouldn't have believed it at first.

So I tried the usual stuff about interference and picking up signals. I replaced the speakers, moved cords, tried a different power socket that wasn't in the UPS etc. That didn't work, but when I unplugged the audio cable from the computer, the sound stops instantly. At that point I can guess either Windows is playing something, or the sound card itself is malfunctioning.

One thing I noticed after being able to listen for a while to the "radio" is that it was fairly random. First it was a Spanish lady talking, then some corny music (seriously, the Harlem Shake song played!) But then it was French, then some American commercials. Sometimes the stations overlapped 2 or 3 playing at once. Also the stations were crystal clear, even when they overlapped, no static. I also heard some audio repeat, I believe the audio could have been on the machine, rather than radio...

You look forward to crisp and satisfying music when a stereo is installed, but static coming out of the speakers is noise that ruins the sounds you expect. Sound is delivered to your speakers using wires that carry electrical signals, which are easily distorted by signals from other electrical devices such as microwaves and power lines. Whether the static is coming through speakers in a car or home, you'll need to use troubleshoot to discover the source of the noise and eliminate it.

Video of the Day

Troubleshoot static out of your sound.

Cycle through each of your stereo input modes. Put the stereo on FM or AM, and tune into a broadcast station you know. Switch the stereo to CD mode and insert a disk. Compare the sound quality to determine if the static deals with an input mode or speaker connections. For example, if your CD plays without static while the radio play with static, this indicates there is a problem with your FM/AM mode and ultimately, the...

If the transceiver is close enough,

any speaker leads will pick up sufficient RF signal to be detected

.

The non-linearity of the amplifier output transistors is differentially rectifying the RF signal picked up in the speaker leads. The resultant DC component is flowing through the speaker coils. Put RF chokes in the speaker leads, or thread the leads through an RF ferrite toroid, close to the amplifier.

UHF on about 480MHz with FM is not usually a problem, it tends to cause key clicks. The FM is narrow band with constant amplitude so it does not demodulate the voice FM component to an audio signal.

HF on 27MHz with AM modulation can be a real problem. You can often listen to one side of the...
