Question about Coby DVD765 Theater System

2 Answers

I am not able to hear the dialog while playing DVDs. The background is great and comes through all 5 speakers, however, to be able to listen to the dialog, I have to switch over to 2-channel or Stereo. The DVD player is connected directly to my TV (which is also a Coby) and does not connect through the DVR box. How can I get the dialog to play and get use out of the 5.1 channel audio output? Seems odd to sell a 5 speaker DVD system that only plays background sound but no dialog.

    Yes, the center channel works perfectly. Actually all 5 speakers work really well, just no dialog.

Yes, I tried several DVDs and it happens with all of them. I'm stumped that the sound is perfect except that there is no dialog unless I use 2-channel or Stereo -- however, when I use 2-channel or stereo, I only get use out of the 2 surround speakers. (I lose center, subwoofer, left front and right front)

Well let me first ask is the center chanel working? or properly hooked up. Cause most of the times when in 5.1 the talking or "dialog" as you put it comes only through the center channel its just kinda how they do it. Listen to see if the center channel is working. if you are unsure try hooking up a speaker that you know works into the center channel speaker output. If no sound comes out then the reciever possible has blown its center channel. Please follow up with a comment and i will be glad to assist you further thanks, Midwes-tek

    Well does this happen with all dvds? cause sometimes dialog can be missing on some dvd's. Some dvds do not have true 5.1 therefor if there is no dialog file it sometimes will not play any sound. In the meantime i am going to review the manual of the device to see if there is some setting that can be adjusted. But if you say the center channel works in stereo mode then i am inclined to believe it is the dialog file itself. Please follow up with a comment and i will be glad to assist you from there. thanks, Midwest-tek

    that is typical with stereo's. On some stereos they will have a 5 channel stereo mode. I looked all through the manual and couldnt find anything about dialog. Except to turn up the center channel but that cant be it. I am really stumped as i have seen this before but generally you have to goto options in the dvd and click play 5.1 or it will automatically detect these settings. I feel that this may be beyond me plesae pass on my solution and hopefully another expert can give you the correct answer to solve your problem. Sorry i was unable to figure it out. Thanks, MIdwest-tek

I record music on Tascam dp2. Why can't I hear my music in all spks. on 5.1 surr. dvd player? I can hear other cds in all 5 spks.

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.

I have background sound on my TEAC HTX1800 DVD player, but I can't hear the people talking. Please help?! Regards /Hester

Chances are you are playing movies coded for Dolby Digital Surround. Depending on what kind of receiver your DVD player is plugged into, the receiver may not have the Center channel operating or turned up. Most all dialog comes from the center channel of a surround sound system. The receiver usually has a separate output for a center channel speaker, and a separate volume control as well. This will adjust the dialog volume up.
If you are not using a receiver, or plugged directly into the TV, check the audio settings on the TV. They may not be set up for the surround, hence why you are missing the dialog. Good Luck

Try selecting different options for the DSP audio settings. Sometimes a simple 2 channel stereo with subwoofer gives the best dialogue intelligibility. I would avoid fancy reverb presets like auditoriums and churches etc. You probably want to find a nice balance between the dialog, the music and sound FX, and the bass (subwoofer) BEFORE YOU START MESSING WITH THE surround speaker FX. Also, you may find that you have to readjust all the settings for different videos. I finally just opted for the simplest, no-fuss approach. Usually the stereo with sub. For really good concert DVDs, you will probably want to use all the speaker configurations that 5.1, 6.1, and 7.1 support.

The speakers wil not play on the background and the center.

If you connected to a 5.1 surround card and checked and they are connected ok you can hear all the speakers when you play music, movies that are in 5.1 format only. If you want to hear also all of them if you listen to stereo movies/music you must set the sound card to emulate multi channel. Also the player you use to listen music/wath movies must be set to 5.1 and must accept Dolby Digital/ DTS decoding if your sound card doesn't(eg. VLC media player-has integrated DD and DTS decoding and codecs for all tipes/formats).

On some dvds only some of the sound track is audible, but no dialog can be heard. Some dvds work fine, but on most rented dvds part of the sound is missing.

on the 5.1 mode, 5 speakers are needed to hear everything. You can usually go in the sound setup menu of the dvd and chooses 2.1 english version. Also, on some receiver, they can be set at 5.1 and actually all of the 5 speakers might not be actually hookup. You can change the ''surround'' mode of the receiver to stereo...

It sounds like she has the player set to output 5.1 surround sound, but only has left and right channel speakers hooked up. Either change the dvd player to only send two channels or hook up a center channel speaker.

Background sound too loud

Thank you, everyone! I thought maybe I was losing my mind. I can hardly watch a lot of the TV shows anymore due to the inappropriate use of music -- either it's too loud or there's just too darned much of it. Come on, TV producers! You are supposed to get better with time, not worse! Thank goodness I'm not alone.
