You'd need amplified speakers, like used for ipods and such, as the output on the headphone jack is a lower volume.

I can't get sound through my headphones on my Bravia kdl-52xbr5 tv. First time I have tried to hook up the headphones which are sharper image wireless


I take it the headphones are charged up and known to be in good working order? Are you using the 3.5mm headphone jack on the side of the TV or the white and red RCA jacks labeled AUDIO OUT (VAR/FIX)? If using the headphone jack the TV should shut off the internal speakers and output to the headphones. If using the mentioned RCA jacks you need to go into the audio options settings and set to Audio System. Also under audio settings, Audio Out, you can pick Fixed or Variable. If you opt for Fixed you will use the headphones to adjust the volume. If you opt for Variable you can control the headphone volume and muting using your TV remote control. Just make sure you have the headphone volume turned up adequately.

Audio out level low


Is there a "audio out fixed/variable" in sound menu? If there is, this would output 'line level audio' vs. variable level by TV volume control.

Ok so 1 of my kidos has the RCA 20F420T tv, and i guess there is no headphone jack hole, so i went and bought adapter that plugs into the av jacks, still doesnt work can you please help!!!


Without knowing the specifics on this adapter - I can provide only provide some clues as to how this works.

Basically, the A/V jacks on a TV has a "fixed" audio output level - this means that the sound levels on the A/V jacks is NOT controlled by the volume control of the TV itself. You should be able to set the TV volume to minimum and then use the adapter's volume control to make the earphone / headphone sound louder and softer. Your TV however, may have a setting in the menu that can change the audio from "fixed" to "variable". If set to "variable", when turning the volume down for the TV's built in speakers will also turn the volume down on the A/V jacks as well. You do not want this to work like that as the sound in the headphones and the TV speakers will be same - instead of the TV speakers being off and the headphones on.

I hope this helps and good luck! Please rate my reply. Thanks!

Marshall MG50 DFX amp line out/headphones not working


Contrary to what's posted above, the Marshall MG series does not pass the speaker power output through the headphone jack, and inserting the headphones into the jack does not disable the speaker. The headphone amp is a separate circuit and it's input is taken before the master volume. So Jan's post is exactly right. Turn off the master volume and turn up all the other gain/volumes as high as they will go. The other issue is that the headphone jack's output does not drive low efficiency headphones well, so you need some headphones similar to Sony's MDR-V700s to hear it well. Earbuds just don't cut it.

The response to your question is in two parts. There should be a couple of RCA jacks on the rear or side of the set labeled "output". These need to be connected to the input of the wireless headset transmitter. The second thig is to determine where the volume is to be controlled. The output from the set can be either Fixed or Variable. This means that teh volume can be controlled by the volume up/down at the set or not. Fixed mode is for connecting to a receiver where the volume is controlled by the receiver and changing the volume at the set will have no effect. Using the variable output mode will allow you to control the level of audio entering the transmitter and thus the volume. This assumes that the headphones do not have a volume control on them.

Setting the output to be either Fixed or Variable is controlled by the audio menu of the set. Please note that in variable mode, any internal speakers would need to be disabled as well.

Hope this helps,
Dan

I bought my rca headphones a long time ago and haven't used them in years. I was wondering, how do I hook them up to my computer. And what all I need to do to hook them to my computer.


Just plug the RCA Headphones Base Station into the headphone or speaker jack on the back of your computer (the headphone or speaker jack usually being green in color), and turn the volume up in Microsoft Windows to about 75%, then adjust the volume control on your headphones to a comfortable level. (p.s. even if you don't use Microsoft Windows, turn the volume up to about 75%, as most computer sound chips are very similar in their output level.)

What is wrong with my audio plug?


Yep, you blew it up, all right.

The headphone jack in the laptop is a low-level OUTPUT which goes TO a set of headphones or the INPUT of an amplifier. You went the wrong way and fed a high-level signal (the guitar amplifier OUTPUT) INTO the laptop.

The electronics inside the laptop are not made to deal with the high level you fed in, so it's been damaged. Ever blow out a set of speakers with too high a volume? That's basically what has happened here.

To fix the problem and get your sound back would require a new system board.

Audio from tv is not restored by turning off power on headphones


It sounds as if you are plugging the base into a standard headphone jack located on the Television set.

RCA Headphone jacks (incl mini) automatically stop the sound output to the main speakers on almost every set I have seen.. or home stereo.. etc etc

In other words you can take a standard RCA jack.. with nothing connected to it.. plug it in while the music or sound is coming out the main speaker.. and it will cut off the output to those speakers..

If you set has audio outputs on the back.. preferably Fixed Audio Out .. you will need to connect your base unit to those.. turn your set volume to 0 and adjust the headset volume using the control on the right ear-cup.

If you have variable audio out.. you will need to go into your TV sets setup menu.. turn off the speaker.. and turn up the set until you achieve a signal and decent volume through the headset.

If you are missing these connections.. your current “work around” is your only solution.

Best of luck
