features Cambridge SoundWorks DTT2500 Written by Clarence Song How Does It Actually Work? From my observations, I found out that the DTT2500 is separated into 2 units. The first unit is the Dolby Digital decoding unit. It accepts its input through the Dolby Digital S/PDIF In and passes it to the Zoran deocoder. Normal stereo PCM signals can also be input to this unit through the Dolby Digital S/PDIF In and it will perform its DAC duties. The second unit is what I call the analog unit. It accepts input from the analog Line In and Rear In connectors. Alternatively, it can also accept these channels through the Mini DIN when a SBLive! is connected. Sound from these 2 units are mixed together and output to the speakers. I believe the main motivation for this was the fact that Creative originally predicted DVD games to go big, with support for Dolby Digital cutscenes. Therefore the original Desktop Theater 5.1 and subsequently the DTT2500 was designed with 2 separate sound units to mix the Dolby Digital sound from the cutscenes with the sound from the sound card. Connection Options Officially, the DTT2500 is aimed at PC users with the SBLive! and Creative's PC-DVD Encore. However, most of the connectors are standard (with the exception of the proprietary Mini DIN that connects to the SBLive!) and would work with any sound card and DVD setup. With the separate Dolby Digital input and the analog inputs, you can connect to a digital as well as an analog source. So a CD player or a 2nd sound card with S/PDIF digital output will work fine together with another device with analog output. Other 4-channel soundcards do work as well, although you have to settle for the analog front and rear line-ins. Do not worry about the analog vs digital issue. Many readers have feedbacked to me that there is little difference in sound quality when a SBLive! is connected digitally through the Mini DIN, or through the analog inputs using the minijack cables supplied with the DTT2500.
