Creative Multi Speaker Surround (CMSS)

CMSS is a 2-channel to 5.1-channel sound processor similar in some aspects to a Dolby Surround with Pro Logic processor.

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 are heard through the center speaker. Use this mode whenever a music program has sounds you want to blend with on-screen action or dialog.

Unlike Pro Logic decoding, CMSS Music, Movie and Four Point modes are appropriate for use with multi- coded sources such as DVD games. In some game titles, the movie sequences may be encoded in Dolby Surround but the game sequences may be in the WAV format. CMSS Movie mode supports 6-channel output for .WAV,

.AVI, .MIDI and other audio software formats. Few, if any of these kinds of formats are Dolby Surround encoded.

The FOURPOINT mode passes the four discreet channel audio of four- channel games direct to each satellite channel. It does not synthesize rear channel output, so stereo signal in this mode will play just through the front two speakers and subwoofer.

The STEREO mode plays the Left and Right Front speakers and the subwoofer. It also lets you hear the stereo downmix from any DVD.

Audio Mode Selection

The stereo soundtracks of some movies on the Video CD (VCD format) contain different languages. For example, a two channel soundtrack may contain Mandarin on the right channel and English on the left channel. The VCD program literature should indicate the presence of dual- language soundtracks. Similarly, some movies in the DVD format will contain dual-language soundtracks. DTT2500 Digital lets you select one of these languages and play it through both the Left and Right speakers.

If there is no indication of which channel is which and you hear two different language soundtracks during stereo playback, select the “LL” and “RR” settings until you find the language soundtrack you want.

The Audio Mode selection feature

can only be used with the PCM digital soundtrack of a Video CD or DVD with a stereo soundtrack, not a DVD encoded with Dolby Digital 5.1 sound or Dolby Surround-encoded material. If you have an analog program with separate left and right channels (the analog output of a CD ROM, or the analog stereo output of a “software” video CD, for instance), you will have to use the balance control in your PC’s audio software to mute the undesired channel.
