My dav-dz270 has no sound from the centre and rear speakers. only the sub-woofer and front speakers produce sound.

blown speaker or x over

Try differnt speakers, if they do not produce sound, amp channels may be blown and then you need to take it to a shop.

You must have changed the listing mode to stereo.In that mode only the left / right & subwoofer will work. Press the surround button and change it to any other mode .

The connection on the receiver would be the sub woofer out. Not a sub woofer out LFE, a sub woofer out with speaker wire connection. From there you plug it in to the top section of the available terminals on the sub you are referring to (speaker level input). One in positive and the other in negative matching what you did on the receiver with correct ends. The speaker connections underneath the top connections is for additional speakers like surrounds to be able to be connected directly to the sub woofer speaker level out for sound. This of course would be for an older receiver connection. I do not think it is possible to convert this connection to an LFE and have it work properly. If the receiver does not have sub woofer speaker connection and only a RCA out then you can try to connect both rear speaker connections from the receiver to the speaker level inputs on the sub and then connect your rear speakers to the speaker level output on the sub to power them. This is an active sub woofer but for some reason they made it connect as if it was passive. I am not sure if this sub is designed for really low frequencies required for movie or if it is better for music.

Please check the connections TV - o/p and DZ810 - I/P ports..!!

These are "decent" quality 5.1 speakers, usually without any trouble.

Now, to your question, you will not have 5.1 "surround sound" effect with standard sound card, standard sound card will provide only three speakers sound, rear speakers will not connect but bass should be hear. Please switvh power off to the speakers and disconnect all cables from spaekers and connect them for best quality as follows:

1. Audio from PC, orange, green and black connecting to front right speaker.
2. DB15 (D-SUB) connecting to subwoofer, subwoofer is serving as mixer, power board, amplifier and connection box, control pod is just cable connection to it
3. Connect all cables to they respective speakers

Establish location of the speakers, from experience, in ideal world:

1. Sub should be on about your knee level or below, about twice your hight from you.
2. Front centre speaker should be about some distance as sub or bit closer on front and slightly above your head.
3. Front left and right speakers should be at about 45degree from your axis, at distance of about 1.5 your hight and on the level of your head or slightly below.
4. Rear left and right speakers should be located similiary to front speakers, on they level or slightly above them, again, about 45degree from your axis.

Location of the speakers is more actually important than it is assumed, total sound immersion is not possible without proper speakers installation. Head in these instruction meant a location of your head while you are listening to your music or recording not while you are standing.

In reality... hang them higher than your head in four corners of your room, front centre higher than sides, woofer lower than sides and below front centre, if they interfere with each other - increase the distance. I hate reality...

After speakers are connected:
1. Plug power cord in,
2. Turn all sounds totally down, including subwoofer
3. Increase sound on PC to maximum, let play any known to you music, tufftuff or bach, whatever, do not bother with metallica as you cannot discredit on it correct levels.
4. Increase subwoofer volume, holding one hand on the front of the grill till you get some vibration from it
5. Increase sound on centre speaker, then on sides front speakers till you achieve equality of the sound
6. Decrease sound volume on your PC to about 60% - 70%
7. Increse subwoofer volume till you feel sound on your hand in front of the speaker.
8. Increase sound volume on front/rear speakers as required.

Hope that short intro solved all your speaker problems, enjoy! if you require any additional help, do not hesitate to answer to this post with request.

Check your speaker settings in Setup menu / Speaker Setup / Manual / Config (and then in this submenu also Equalizer).
In Config, choose where should low frequency sound go - subwoofer and/or front speakers (if they are big enough). The settings are: Bass Out: SWFR/Front/Both.
Also check Subwoofer phrase in SWFR Phase.
Check settings of all speakers, they can be Large / Small / None. If small, frequencies lower than "Crossover" settings, will not be put on them.

this might be happening because the audio format for surround is not supported by the channel or affiliate of the channel that you are viewing does this happen on all tv channels or is it on just a few? if all sound while playing a dvd is proper and in working order than there must be an issue with the sound and or format of sound from the tv source. maybe more information would help me decipher this

anyways hope it helps
Ryan

first check the settings of woofer or dvd player (keep in 5.1 mode and RAW)

mail me clearly about the problem,
