DDTS-100 Squeelching Problem

Hi, I have a problem with my DDTS-100 and i can't seem to find a solution anywhere. I'm Using the Promedia 5. with them. My problem is whenever i play music, watch a movie, or play a game the DDTS-100 emitts a squeeling sound from the front left and right speakers. when i play somthing louder, the squeelch is much more noticable and very annoying. I upgraded from the Promedia DD5. so i could get prologic II and DTS:neo6 support, which works really well by the way, but i never had this problem on the DD5.. If i hear the squeeling, i can pause the music or dvd or whatever and it will still make the noise. when i mute the DDTS-100, the squeeling stops instantly which shows it is the DDTS making the sound. if i turn off mute, the squeelch is still off until i unpause or music or movie again. then the squeelch starts up gradually, but quickly like this: ssssqqqquuuuuueeeeelllllcccccHHH. i'm pretty sure its not an electrical interference since if i plug coaxle from my dvd player and my xbox together i get a hum, which is differant from what i'm talking about. so its not so much a hum, but a squeeling. lol sorry this post wasn't very organized. but i really need help on this one. Thanks in advance.

Oh yes, sorry. The crossover is in the computer soundcard settings which of course, you won't have.
To test the sub you could try connecting another channel to the sub input, say the centre. If you hear the bass component of the centre channel at a decent volume level then you know the problem is not with your amp/speakers but with the ddts-00. If this is the case, then I think you should contact technical support. If you look here,http://forums.creative.com/creativel...message.id=722, someone is having a similar problem, but they clearly say that the subwoofer output on the ddts-00 works fine with movies, so maybe yours is faulty.
EDIT:
I've found an examle of a crossover that is designed for 5./6. systems. I have posted a link to it in the above thread.Message Edited by pjc on 04-8-2005 0:32 PM

Decoder DDTS-100 upmix problem w analog inputs

I've had the decoder for some time and it works fine with everything else (real sorry to see it's discontinued!!). But now I have a digital radio (WorldSpace.com with a Tongshi DAMB-R receiver) which outputs 2 channel stereo analog output, and the decoder only plays subwoofer, left, rt, and center channels in my 5.1 system -- i.e. there's no rear sound at all. Other analog stereo inputs to the decoder give me fine 5.1 sound. It seems to me, naive at these things as I am, that any 2 channel analog stereo should upmix to 5.1 like any other. But perhaps there's some funny bandwidth compression going on in the radio so it won't upmix to 5.1 There aren't any settings on the radio to adjust things that I can see.
Any ideas on a workaround or at least illuminate me why this might be/is happening?
Thanks,
BaliDave

First of all, the ddts-100, is just a 6.1 decoder, and doesnt really support 7.1.
To get sound through every speaker, you will need to activate the 6.1-7.1 upmix, via the upmix switch on the back of the subwoofer. Then the rear right speaker should play when the rear left speaker does, as the 6.1-7.1 upmix, splits the 6.1 signal, and makes it 7.1.
Also, for movies with 5.1 sound, like Dolby Digital or DTS, you will need to set the switch to 5.1-7.1, unless you want to upmix the 5.1 sound to 6.1 via DTS ES Matrix or Dolby Digital EX.
When connected to the soundcard via digital spdif, you will only get stereo sound, as long as the sound isnt in digital AC3 (dolby digital/dts), so to get true surround sound in games, you will need to connect via the switch box with a analog connection and bypass the decoder, by setting the switch to "PC".
But when wathing DVD's, I recommend using the digital connection. (You can allways use the analog connection though, but if you do, the soundcard will do the decoding, and this can cause some quality loss at times.)

DDTS-100 and Divx/Xvid files

Does the DDTS-100 have problems with DivX/Xvid files that are encoded with AC3?
Power DVD will pick up a true DD signal for a DVD, but if i convert to avi (divx) with the ac3 sound, it only uses Pro Logic II/Neo6. There isn't even the option in Power DVD to use spdif when playing an ac3 divx file.
Who here has the DDTS-100 and can play AC3 divx files fine with TRUE DOLBY DIGITAL?
Cheers.

Well this went down like a lead balloon.
If anyone else finds this, a solution is to convert the divx file to dvd vob files. The DDTS-100 will pick up the true digital signal if they are vob files, converted from divx with AC3 sound.
I use 'VSO divxtodvd', you can google a link.

DDTS-100 Decoder with Inspire 5500D 5.1 Speakers (DIN Problem!)

Dear all,
I bought a DDTS-100 Decoder today, thinking it will improve connectivity and sound quality of my Inspire 5500D 5.1 Speaker System, but I have run into a bit of a problem. My system has a sub which every speaker is connected to and I have to have the DIN cable connected for controlling the speakers and sub but the DDTS-100 doesn't have a din slot so my speakers will not power on when connected to the ddts-100. Is there a way around this or will I have to take back my decoder. I hope there is a solution as I would be very thankful.
Yours Thankfully,
Kyle Hunt.

Centre channel problem with DDTS-100

I have a set of Gigaworks s750 speakers connected to my PC, PS3 and Xbox 360 via the DDTS-100 decoder; up until yesterday this was all working fine. Having moved some of the gear around to accomodate my new desk, I plugged everything back in and found that the sound from the front centre channel is muffled and/or quieter than the other channels.
The speakers themselves don't seem to be the problem as the PC (which is connected via the switch box included with the decoder) sounds fine but the problem persists with both the PS3 and X360.
My first thought was that I'd pulled one of the cables loose while rearranging the furniture but I've re-plugged everything in several times since with no joy. I've also tried changing the spdif cables and switching the sockets around, as well as removing the switch box and plugging the speakers directly into the decoder but nothing made any difference.
Has anyone ever encountered anything like this before and/or could offer any suggestions?
Any advice would be much appreceated.

I finnaly found out my problem
The buzz came out from my coax cable from my DVD. My DVD player was probably inducing 60Hz on the coax output.
I switched to the optical output and no more buzz.
I'll need to buy a new toslink cable to plug my x-box on the optical input #2
Also I pluged my TV audio out in my st analog input, it also induced a 60 Hz on my DDTS-100. The decoder does not seem to filter out electric noises.
I'm pretty happy to have found out my problem but I'm very dispointed that the DDTS-100 does not filter any electric noises.

Hum problem with DDTS-100 with Klipsch Promedia 5.1

I have a problem with me decoder DDTS-100 since the beginning. I use it with Promedia 5.1 Klipsch kit.
When I use digital sources either optical or coax, when my decoder does'nt receive any signal from my DVD or X-box, I am earing a big hum coming out from my speakers. And then when my DDTS-100 receive a digital signal the hum disapeer.
I am not earing the hum when I use the analog input.
I am very disapointed about this bug because when the volume is high I am worried about my Klipsch kit.
Thanks in advance

DDTS-100 & Gigaworks 7.1 Problems

Hello all,
I've recently moved, and installed my DDTS-100 with Gigaworks 7.1 on a new TV which is also attached to a new cable jack. I have it set to 6.1/7.1 on the DDTS and 6.1->7.1 upmix on the Gigaworks. I'm bothered because I cannot get the sound to come out of all the speakers. I hooked the TV audio out into Analog on the DDTS-100, and I am accepting the stereo channel, but when I turn it on, sound only comes out of the middle speaker when Dolby or NEO:6 is selected. I can select stereo, and sound comes out of the front two, but not the middle. I miss NEO:6. Does this mean that my cable is only providing a mono signal? Is there something I might do?
Also, I just recentl got an XBox 360. I hooked it up optically to the DDTS-100. When I leave it upmixed from 6.1->7.1, sound only comes from the front and side speakers. When I change it to 5.1->7.1, it comes out of all of them. This does not seem correct as the DDTS-100 is set to 6.1. Do I have anything wrong here as well?
Thanks in advance.

Hi Chris,
Firstly, If you are getting audio with the THX optimiser, and via other DVD's, it doesn't appear to be hardware related - logically, the hardware can only output what is actually put into it (i.e. the audio datastream via the software)...
...Meaning this issue probably originates from the software 'encoding' on the disc itself. As you say, it won't actually be a direct fault with just your DVD e.g. a scratch or something similar. However, it seems to be how the disc has been encoded, but I can't be certain :smileyindifferent:
Anyway, hope that's of some help & you get it sorted whatever it turns out to be.

Problem with subwoofer on DDTS-100

I have bought the DDTS-100 decoder recently. I have a DVD with optical output and Luxeon LogicFox T5.1 Home Theatre system. When I connected everything there is no subwoofer. The other channels work fine, except the subwoofer. Yesterday I returned the decoder to the computer store where they connected it with some creative speakers, and the subwoofer worked. But why I can'y get no subwoofer on my non-creative speakers?

Normal decoders take a slice of the bass from the other channels and put that through the sub woofer as well. This is called a "bass management" feature. The Creative decoder does not do this.
Most speakers will only put sound through the subwoofer if they get a signal directed to the subwoofer itself from the decoder. Creative speakers, on the other hand, take a slice of the bass from all the signals and put it to the subwoofer. You can test this by hooking up a CD player to the L/R input jack on Creative speakers. You'll get subwoofer output even though the subwoofer channel is supposed to be dead.
So, if you've got a normal decoder hooked up to normal speakers, it'll work fine, sending some of the bass from everything to the subwoofer. A set of Creative speakers hooked up to a Creative decoder will do the same thing. However, if you mix and match the systems, you'll get odd behaviour. A Creative decoder with non-Creative speakers will give you none of this bass-redirecting.
I believe this sort of design is called "manufacturer lock-in", intended to make you use Creative products in conjunction with other Creative products rather than their competition's.
Edit- You SHOULD get bass when a DVD etc. is sending a signal specifically to the subwoofer channel, though. Try to find a DVD with an explosion in it and see if you get any bass during the blast. If you aren't then your sub may be borked.

DDTS-100 power plug problem please help!

I wanted to order the DDTS-100 online but I can only choose the 3 pin uk plug. What i need is a 2 pin plug, i don't know exactly which one(I live in the Netherlands.) How can I solve this?

just get the 3 pin one and then either use a converter (can be bought in most electronics stores) or see if it's possible to replace the cable entirely.

Creative inspire 5300 5.1 with DDTS-100

Hello i'musing these set of speakers for 2.6 years and now decide tobuy decoder DDTS-100 but there is a problem ca't connect them and creative labs are saying this decoder is compatible with all speakers from creative !!!
Any information how to connect will be wellcome many thanks
Filipe Valente

Just connect them using your speaker audio cable from the decoder audio outputs jack to the speaker system audio inputs jack. The decoder user guide should also cover some simple guide for connection too which you can refer to.

PC and DDTS 100 simultaneously

Hello,I have an actually simple problem I can't solve with out help...here it is:I want to connect my PC Soundcard (Creative X-Fi xtreme Music) and the Decoder DDTS-100 to my Soundsystem GigaWorks S750. I realized this through the use of the Switch Box accompanying the DDTS-100. But: With this box I only can choose between PC Audio and the Decoder, thus it's not possible to listen to both of them simultaneously. What can I do?

Hello everyone. I just responded to a post in 'speaker systems' regarding the S-750. Read that for more details.
Anyway, I have the DDTS decoder with the S-750. It really rocks!!!!! Better than most mid level home entertainment systems!!!
I have all the connections filled on the decoder (Analogue, optical etc. to various things) It is not connected to my computer. It is my home entertainment system. My setup is where I have all the device vollumes set to there highest levels including the S-750 and I use the decoder to manage vollume levels.
The only problems I have had so far are 2.1 Once the decoder turned off when I touched it (Static elec. I guess) The other was I turned it on and no sound came through. I cycled the optical selection and it came on.
How is everyone else doing? I had the system for about 3 months now.

DDTS-100 Issue

Hi,

can anyone help, i dont get this issue with my dvd player.

Anyone?

Help.. What sound card to go with ddts 100??

HI everyone,?I just bought my samsung lcd tv and i am very anxious to get the ddts-100. But the problem now is: What sound card should i get? Get a Xi-Fi Extreme Music or just a cheaper soundcard will do since the decoding will be done by the decoder. Can anyone advise on this? I hope to spend lesser on the sound card but if it is really needed then i will get good one. Thanks.
Regards,Kekin

Bear in mind the DDTS-100 will only decode Dolby and DTS (and their varieties). That is, it will happily decode the surround from a dvd (assuming your soundcard and software passes it over the digital) but it will only get stereo when gaming or using CMSS for music.
So, the DDTS-100 is a great partner to a standalone dvd player, games console, and whatever else you have hooked up to the tv. It will also play nice when watching dvds on the pc. It has a good upmixer for music and stereo tv too. If thats roughly what you had planned then it will fit that role nicely. Its also more convenient than switching manually over to the pc (with the switcher box) when you want to use it instead of the decoder.
If you were planning to do everything on the pc then it may be a bit pointless as your soundcard and software could do it all instead. Also, i suspect the quality will be better from a decent X-Fi than the DDTS-100 but havent got around to doing a comparison yet.

Help connect X-fi Elite Pro with DDTS-100 and Gigaworks s750

Hi,
I purchased a brand new Gigaworks s750 speakers system, DDTS-100 decoder and X-fi Elite Pro. I connected the DDTS-100 and Elite Pro using Optical Fibre output from the audio console of X-fi Elite Pro to the optical digital input of DDTS-100. With the cables supplied with s750, I connected it to the Decoder DDTS-100. The problem is I am not getting any sound from the rear speakers and the front speakers. Only the centre speakers and the side speakers are producing sound. I could hear loud hissing sound and very very low volume of the music from the front speakers and no sound from the rear speakers. I can hear good quality sound from the centre speakers and average quality sound from the side speakers. What could possibly have gone wrong with my setup ? Somebody please help me. Thanx in advance.

Hi Richie,
Thanq for your response. But unlike what you have mentioned, ("what may be happining is the soundcard is decoding the signal and then the ddts is trying to decode it with disatrous results"), In my setup the signal is not getting decoded two times, once by Soundcard and once by the DDTS-100. As I have mentioned that I am taking out an Optical Signal from the sound card to the DDTS-100, the signal comming out from the sound card to the DDTS is Encoded signal only. So there doesnt arise a chance that the signal is getting decoded twice. Can you think of any other reason why my setup is not working? Please let me know.

DDTS-100 + i-Trigue 5600 + CH-DVD 462 center channel issue? Please help...

Hi there,
I'm having some problems with this setup.
My DVD player is set to RAW output.
All cables are connected properly (checked, double checked)
When playing most 5.1 content (Dolby Digital track from DVDs) surround works perfectly except for the center channel. It's completely deaf. If I set the decoder to Stereo output, it works, so I know it's not the speakers. I tried some tests (7.1 THX Optimizer tests present on some SW DVDs) and the center channel works here (but the other ones are sort of messed up), so I assume it's not the decoder either.
I tried the center/sub switching cable that came with my last speaker set, and though it does switch the channels (I can hear mumbling dialogs in the sub channel) the center channel remains deaf.
So I know that the sound actually makes it out of the DVD (RAW is RAW) to DDTS-100 and from DDTS-100 to the speaker set (yep, the signal's here but I can't hear).
I should mention that I used competetive speakers before and had a similiar issue with the subwoofer channel - it made sound only for the LFE DVD channel as those speakers were not doing subwoofer channel computing (AFAIK Creatives do (bad bad bad bad)), but I assume DDTS and i-Trigue 5600 are supposed to be compatible...
I'm completely puzzled. Any suggestions?

shin8,
Are you getting proper output if you use the "TEST" button on the remote control?
