Cambridge SoundWorks DTT2500
Written by Clarence Song

CMSS Modes

Most audio from TV broadcasts, MP3s to CD audio are all in 2-channel (stereo). What Cambridge SoundWorks has done is to provide a CMSS Music and CMSS Movie modes. These presets takes the stereo input and spreads them out to a 5.1 configuration. So instead of hearing music from the left and right channels only, the center and surrounds are also used. The sound is spread out very nicely.

The surrounds are used to recreate the ambient and mid-range information that the decoder is able to extract from the stereo source. This is similar to what you would hear from the surround channel output by a standard Dolby Pro Logic decoder.

I couldn't make out much difference between the Music and Movie modes. The manual provides this explanation:

CMSS Music mode creates a convincing 5.1 channel surround soundfield with typical stereo sources, whether they are Dolby Surround-encoded or not. It works well with Dolby Pro Logic, WAVE, AVI and MIDI program material. In essence, CMSS Music mode puts you "on the stage" for the music's performance, surrounding you with the performers.

In a similar manner, CMSS Movie mode provides the sonic impression of being front and center at a movie screening. Dialog and all normally centered sounds from a stereo program aer heard through the center speaker. Use this mode whenever a music program has sounds you want to blend with on-screen action or dialog.

The FourPoint mode works simlar to any other 4-channel speaker system like the FPS2000. The front and rear channels from the sound card are reproduced while the center channel is turned off. This mode is used when playing games that produce 4-channel sounds.

And finally, the plain old Stereo mode turns off all the channels except the front left and front right. Sometimes you may want to sit back and just listen to a nice piece of music with just the left and right channels, just like the way the composer intended it to be!

In all the modes, the subwoofer is still turned on to reproduce the low-frequency sounds.

The CMSS modes are adds value to the DTT2500 by enhancing the normal stereo programs to 5.1 which is pretty cool, since you've paid for 5 speakers to be placed around you! :) Its a waste if the center speaker only works when watching DVDs.
