Bob, welcome

Check to see if your DVD player is equipped to play DVD-AUDIO music discs, or the Sony version SACD.

If you have one of these DVD players, the 6 RCA analog audio outputs are for these discs only. To play these discs, you must have a receiver equipped with 6CHL INPUT in the rear.

roberto, what is the make/model of your DVD player? If you live outside of North America, you may have a different model. Also what amplifier do you use, or are you connecting the DVD directly to the television?

No, you cannot plug the analog audio 6 cables to powered speakers.If I am correct, the 6 cables out of the DVD player carry UNDECODED analog signals which must go to an amplifier's DACs, that is, Digital to Analog conversion or Analog to Digital.

Those 6 RCA plugs DO carry analog signals, not digital.

But while you CAN plug self-powered speakers into the sockets, you really dont want to.

For one thing: how are you going to adjust the volume?

You need a pre-processor or a receiver with analog outputs to handle the various processing needed prior to sending the signals to a speaker.

I think I would give a different answer. I'm guessing that what Bob wants to do is plug the DVD player directly to powered speakers of the sort sold for use with PCs. This will work OK, as each speaker (or pair) has it's own volume control.

As was mentioned, the output is analog, and is the sort of line-level output that powered speakers expect.

Actually, I guess you could. When you wanted to adjust the volume, you would need to adjust on all three pair of speakers. The odd part would be, the sixth RCA jack is for the subwoofer (LFE) sound. most powered speakers are not ready to deal with the level/frequency of sound. Wayne.

P.S. you would be better off connecting to receiver, but if you have the powered speakers already and want to hear what 5.1 sounds like. let it rip.

This is not good information.

These outputs on your DVD player are decoded analog 5.1 Dolby Digital signals and can be sent directly to powered speakers. (The undecoded signal is digital, sent from the DVD player via the digital coaxial or optical output.) However, as some have noted this is not optimal because it will not give you any master volume control.

But the worst part is that most budget powered speakers (and I assume that’s what you want to use, right?) don’t have much power – maybe 10-20 watts. With movies you will find this is simply not enough, and the little amplifiers in the speakers will clip regularly.

Dolby Digital receivers have provisions to compress the audio signal and limit dynamic range. If your DVD player has a similar setting, you will for sure want to use it.

technically, this would work. as already mentioned, you'll have problems controlling the sub out...i doubt the powered speaker will be able to handle the lower frequencies.

should be interesting though...

btw - why are you trying to do this? just curious...

Bill, in relation to your question

-----------------------------------------------------------

roberto, what is the make/model of your DVD player? If you live outside of North America, you may have a different model. Also what amplifier do you use, or are you connecting the DVD directly to the television?

-----------------------------------------------------------

My DVD player model is Crown Mustang DVD-838 it is the same model of Scot DVD-838. It is connected to a Technics receiver model SA-GX170 (just stereo, not dolby). And the video out is connected directly to my 29 inch. Samsung TV.

Ted. about your question
btw - why are you trying to do this? just curious...
i am trying to do because in my country is very expensive
to buy a receiver and a six speaker sistem, in early days
this was possible but not now...

And i think... why not to buy some self powered speakers (not to expensive, but not to bad) and connect them to my
dvd player.
thanks for your question...
Regards
Bob.

hi, me again, just two questions.
1. Anybody knows the 5.1 speaker system by Edifier model
r501t ? what do you think about it? www.edifier.com/en/htmls/r501t.htm
2. It exists any other way to make my own 5.1 system not to expensive?, i think to build my own but i dont have found any information to make this.
Thanks all.
Bob.

hi bob -

1. i'm not sure about that 5.1 system. it only runs 8w or something like that...that's way too little wattage. also, something about it just doesn't seem "right"...

2. i can't think of any alternatives for you. i know you stated cost is an issue, but maybe you can find some good used gear (ebay?) or save up? at the least, i'd recommend a receiver and an inexpensive 5.1 speaker package.

I wonder how much that speaker system would cost.

I bet you could find an A/V receiver online for about the same amount. Then you could go the route I'm going--build a system one piece at a time. Right now all I have are the A/V receiver and two speakers. Later this year I'll pick up the DVD player. For christmass, some more speakers, etc... The nice thing about aquiring standard equiptment slowly like this is that it makes upgrading to better equiptment later easy.

If you buy those powered speakers, and then get an A/V receiver. You won't be able to take full advantage of the A/V receiver until you get a new set of speakers that can handle the greater level of power. In essense, you'll have to start building from the start all over again.

Bob needs advice here because he is posting from ARGENTINA where if you haven't kept up is suffering a major monetary devaluation. Buying on Ebay in the U.S. likely isnt an option for him. He wants to see where he can MAKE DO. I have no further technical advice for his situation, however.......

...just speaking softly here
