catsfelix Posted November 2, 2003 Share Posted November 2, 2003 hi guys, if i already had sound card that support for DolbyDigital (SBLive!Audigy2), do i still need another decoder like Klipsch DD? Quote Link to comment Share on other sites More sharing options...
jackson_ngo Posted November 3, 2003 Share Posted November 3, 2003 nope, your sound card is already a DAC device. Unless u need to decode DTS singnal, then i think the 5.1DD is needed Quote Link to comment Share on other sites More sharing options...
catsfelix Posted November 3, 2003 Author Share Posted November 3, 2003 mm.. sorry but what is DAC device and what is DTS? do they use a different decoder with Dolby? when the movie is played, can we use those 2 sound formats at once (dolby & DTS)? if we hv a speaker that has a decoder built in (dolby, dts) and our sound card is also support it, will the sound get crash? or.. if i hv a built in decoder speaker, do i still need a sound card like Creative Audigy? i'm so newbie that need to learn a lot . ). ur advice will be so much appreciate thx Quote Link to comment Share on other sites More sharing options...

DAC stands for "digital-analog-convertion". digital sound comes in the form of CDs, DVD, mp3 and midi, where analog are VCRs and cassette tapes. speakers that supports digital input will have either the SPDIF, Otical or Coaxial input. while analog speakers will use the minijacks and RCA jacks. For example if you are playing a CD on a pc using an analog speaker, then the DAC of your soundcard is in used. If you are connecting a analog device to the soundcard when you are using a digital speaker, then the ADC(analog-digital-convertion) will be used. Dolby Digital and DTS are two difference kind of digital sound format. they are used in movies today for a more acurate and better surround sound. But DTS is much better than Dolby Digital in term of quality and accuracy. some dvd only have supports dolby digital audio while some supports both dolby digital and DTS. dolby digital and DTS is not possible to be used together and you will not wanna use it together. it'll sounds like having two source of audio playing together..argh... since the audigy 2 supports both dolby digital and DTS, i don't see the means in buying the klipsch 5.1DD. some says the klipsch 5.1DD does improves the quality, you can buy it if you want it, it's all up to you to decide whether you wanna spend the extra bucks for the better quality. Of course you can use both 5.1DD and DTS enabled soundcard together. but the DAC on the 5.1DD will be wasted. even if you are using a speaker with decorder, it just means that you have one more DAC in your speaker system, speakers are recieving analog signal anyway. The cables you using to connect the satalites to the amplifier are actually sending analog signal. Sound in real-life are analog Hope that helps you Quote Link to comment Share on other sites More sharing options...
whatsup Posted November 5, 2003 Share Posted November 5, 2003 I don't think the Audigy 2 supports DTS but the Audigy 2 ZS does. The latest full version of most DVD software players usually support all decoding formats, so you also have that too. My understanding is that the DD 5.1 is really for connectivity to devices that don't have a decoder. Quote Link to comment Share on other sites More sharing options...

catsfelix Posted November 6, 2003 Author Share Posted November 6, 2003 o yes, guys one more thing. is every decoder the same ? i mean, is Audigy2 decoder as good as hmm.. let say AltecLansing ADA890 or Logitech z-680? can we rely on speaker's built in decoder? or maybe we need more high quality decoder (maybe such as Audigy or M-Audio Rev.) for a greater sound experience? thx guys..

jackson_ngo Posted November 6, 2003 Share Posted November 6, 2003 opps it's my mistake. i mean the Audigy 2 ZS, not the original audigy 2. whatsup, it's true that the 5.1DD ofers connectivity to devices, but it also offers DAC decording of DTS and dolby digital signal. The output offers on the 5.1DD are 3 pairs of RCA jack(rear, front, sub/center), for the use of analog speakers. catsfelix, it's not nessary to get a digital speaker for eg. ADA890 or Z680 unless you wanna plug in a DVD player directly into the speaker without the use of your soundcard. For better connectivity, get the audigy 2 ZS platinum models. They allow you to connect digital audio device(eg. PS2, DVD players) and offers DAC to the signal. plug in an analog speaker to the soundcard and there you go with DTS and dolby digital audio Quote Link to comment Share on other sites More sharing options...
doudou Posted February 4, 2004 Share Posted February 4, 2004 so you don t need the DD5.1... but with the DD5.1 you don t have to run your pc to have multichannel sound... it depends on what you want to do.... Quote Link to comment Share on other sites More sharing options...
