DDTS works as a hub for all your equipment so you in an easy and smooth way can connect everything to the same speaker system. So, what is DDTS, this little thingy which obviously has managed to confuse a whole lot of our readers? To clarify myself a bit I quote myself of the conclusion:. Shall we begin with taking a look on what is offered? DDTS is basically an audio decoder.
We have outputs and inputs which probably will satisfy most of the needs. Most of what you can think of can be connected to the DDTS Game consoles, computers, MiniDisc, MP3-players, in short everything with a digital output or even an analouge stereo output. When it comes to speakers you are limited to those with analouge connection.
Except support for 5. With this you can also use the DDTS with your creativd. Thus in total you can have up to eight different units connected simultaneously into the decoder. Not many people need more than that and the crazy people who need more than ddtd-100 have probably bought some extremely more expensive equipment anyway.
The unit itself can be placed standing or laying down. But such things of course also depend on how you have decorated the room. We are offered a whole lot of controls in the front. Ddtss-100 can control the volume for the whole system and even for different speaker pairs at the time.

Of course here is also control over what input you want to listen to for the moment. The fact is that most of the stuff is controlled by the remote. Here we find all the inputs and outputs and a small ddtw-100 for what speaker setting you want to use. We begin with the top row and go from left to right. First we have the switch which chooses between 5. Last but not least we have three coaxial analouge inputs for example xdts-100 CD player etc.
If we take the lower row we first have the contact for power supply 16v adapter.
And last but not least we have the three analouge outputs where you connect the speakers or the switch box. If we return to the front I have some comments on the esthetic. First of all I must say that the impression has varied between those of my friends who has looked at this unit. Personally I am neither really negative nor really positive. It is true that the creation gives a rather plasic impression. Little plastic and chubby but not ugly. So despite what you think about the looks of it you can easily place it wherever you want.
In short not a master piece of design but on the other hand not too painful to rest your eyes on. The most important is admittedly the functinality and there the DDTS is brilliant. We have looked at the main unit itself and now we take a look at the two important remaining parts of the package: With seventeen buttons you have got quite a simple control over all the functions that DDTS has to offer.
A volume control for the whole system and for separate speakers is also present. We had a quite weird problem with both the speaker systems we tested one 5. It is quite big both in length and height despite that there are so few buttons on it. The buttons are OK though. Personally I think that they should have put more effort in it. Finicky, I know, but I still have to say that they get a few minus points because of the remote.
Above you see the so called switch box. You use this if you want to connect your computer to the decoder. If we are going to be picky again we would gladly have seen that they would have implemented this function directly in the main unit and that one would have control over it in the remote. We picked a for the task appropriate screwdriver and opened up the unit to show you a couple of photos of the inside. Note that this voids your warranty so this is nothing you should do at home.
Observe that these images are taken with a very low quality digital camera and therefore are under all criticism. Unfortunateley we had no other camera available within reasonable time since this was an idea we got in the last second. Please notice that this was mostly thought as a fun sidetrack. In other words we have not poked around to see what specific components Creative has used for the unit. Anyway as you can see the heart consists of three circuit boards.
As we mentioned in the introduction the DDTS is not an soundcard or anything similar. DDTS is mainly for decoding digital audio streams but also analouge ones. On a later time Dolby has introduced a modification of the format, Dolby Digital EX, which has got support for an additional speaker.
In that way we have been able to enjoy 6. This technique is called Matrix differing from Discrete which implies a real channel. With this analouge format you can matrix in two extra channels in an analouge stereo signal. Dolby ProLogic II has also got the ability to mix up stereo to surround.
When you do this you can choose between Movie or Music depending in what material you are listening too. The new format promised better audio quality than what DD could offer with a bitrate at up to 1. The format was introduced with the movie Jurrrasic Park in To clearify we have made a list below. Dolby ProLogic is a technique for a decoder to mix up 4 channels from a stereo source. Dolby Digital is a format for digital 5. DTS is a format with higher bitrate than Dolby Digital and also contains 6 5.

The format can use two different methods: Another unique thing that DTS Neo: DDTS has got support for all the above formats plus a few more or less obvious ones. We have mentioned bitrate in a couple of places.
Bitrate, which is measured in Kilobits or Megabits per second, is one of the factors that determine how good audio quality it is. There are three other factors though that are in principle just as important.

First of all the number of channels. How many channels have to share the bitrate that the audio stream has? A stream can have a bitrate of 2 Mbit but there is maybe 6 channels which have to share this bitrate. The last two factors which also are important is the sampling frequency and bit depth. Thus a CD with its Finally we have the bit depth which simply specifices at what precision the audio is stored.
We can make a parallell to the color depth that is shown on your monitor. Dolby Digital follows the same trend but has much lower bitrate. On the other hand Dolby Digital has clearly got better compression algorithms. Note that all the formats, except Audio CD, can be delivered in other configurations than what we have listed in the table.
What we have in the list are guide lines. Sometimes we have given nominal values, sometimes the maximal and sometimes just the most common.
Another very important thing to understand is that different compression algorithms gives different audio qualities. The best of all algorithms is lossless compression. Between two different lossy compression codecs there can be a major difference in quality.
What nForce2 does when you connect it digitally to an amplifier is that it on-the-fly compresses all audio to Dolby Digital 5.
The result of the whole is that you compress the audio very hard thus you lose a whole lot of audio quality. There has been a whole lot of misunderstanding concerning what SoundStorm does and one of the misunderstandings has been that the audio would be better since you used the optical output.
This is about as wrong as it can get. If we shall whine a bit more about SoundStorm it is that the compression applies a small delay which also worsens the whole experience.
Despite this many prefer the simplicity of just having to plug one single digital cable to the amplifier. For those who want to simplify the cabling at the cost of audio quality and performance the DDTS is an excellent addition to those ceeative nForce2 and SoundStorm.
To install the DDTS is easy. You simply connect the DDTS to the wall outlet and then plug in all your equipment. Since everything is connected with one cable per unit, as long as we talk about digital audio, it is smooth and impossible to do cerative. Of course it requires a speaker system. It was also such a speaker system we used in the review. Since we also connected a test computer to the system we used the so called Switch Box but also this rceative very straight forward and without any difficulties.
