I am able to hear only music, but no vocal on some dvd's, why?

The vocals are directed to the centre channel. If this is not connected or the connection is poor then it will mute the sound of the vocals.
If you want you can select stereo mode when listening to just music. Not the surround modes. Or you can check the centre channel is working and not switched off. Some amps have the ability to switch speakers off in different modes or settings.

Do you have a surround mode turned on? Most vocals will come through the center channel. If you have a surround mode selected, and no center channel speaker hooked up you will lose vocals.

When u record music, its important that the background music be at -7db and the vocals should bounce the level meters to just over 0 db,also if u use a mixing console to add more instruments to the mix, the mixed output of the added content MUST BE NO MORE THAN -7db in order to maintain balanced music output to all channels.

Note that you MUST use the special Karaoke disks to be able to remove the vocal... it will not do it for plain music CD's. Those devices that CLAIM to remove vocals often do so poorly... they do it by subtracting the left and right channels which ASSUMES the lead vocal is centered between the channels... Those methods don't work very well...

Do you have the left AND right channel hooked up to the back of your tv? Sometimes your dialog may come through one channel and the music from the other depending on what kind of telesvision you are using. Try that and then make sure you don't just have your player set to do close captioning and have the vocal dialogue shut off.

This could be your equalizer settings or maybe if you have a surround sound, it could be broken.

check the setings

Greetings surfjax,

If you will allow me to make an assumption, you do not have a 5.1 surround system connected to your DVD player. This is a common experience with users of a standard TV or stereo receiver if a movie is being presented in 5.1.

In a surround sound system the center channel speaker provides almost all the vocal tracks while the side channels will provide music and some background noises. You'll still be able to hear the voices in your side speakers, but it will be muted and over powered by music or sound effects.

Some DVD players allow you to "Downmix" the surround signal to stereo. You might want to look around your sound setup on the DVD player or check your owners manual.

Hope this helps.

Go Ahead. Use Us.

you probably set the audio for 5-channel. In a 5-channel set up. Which it doesnt sound like you have there is a 5th speaker in the center of the dash dedicated for clear vocals. Play with surround options and i'll bet you can fix it

Maybe your headphones are pulled out halfway.
