Desktop Theater 5.1 DTT2500 Digital - Page 3

Check Out the Engine
Encased in a small black box is a 24bit Dolby Digital decoder and six channel amplifier that drives 7 watts each to the front left / right, and rear left / right surrounds; 21 watts to the center speaker; and 20 watts to the subwoofer. At the back, there are RCA jacks for connecting the various speakers, a coaxial digital input for Dolby Digital and S/PDIF signals, and two mini-jack type analog inputs for stereo, Pro-logic support and FourPoint Surround (for 3D Sound Cards that support multiple speakers, like SB Live, MX300). It also comes with a switch to auto detect signals coming in and turn on the appropriate sound modes.

This time round, Creative has also included a Digital DIN (Creative proprietary digital format) that lets you transfer digital audio from Sound Blaster Live! directly, in conjunction with the front and rear analog outputs. And lastly, a nice feature is the Subwoofer Line Out slot that lets you hook up an additional, preferred powered subwoofer. But honestly, the subwoofer in the package would give you more than enough power and balance to be satisfied.

On the Front panel is a power button, main volume control, and level controls that can individually alter the center, subwoofer, and surrounds’ settings. The Creative Multi-Speaker Surround (CMSS) button alternates between four DSP modes – Music, Movie, Stereo, and Four Point Surround. And the Dolby Surround button toggles between digital and analog input. There is also a mute button, a speaker test calibration button that sends test tones to each speaker, and an audio mode button that lets you play just the left or right channels of a stereo digital signal. This is especially useful with material that has different languages / audio encoded separately in the left or right channels. Seems like the only component missing is a remote control that would have rendered the setup perfectly comprehensive, even though it would have raised its price.

Let’s look at the specs:


  • Each main, center and rear satellite speaker features a 2.5" long-throw speaker driver for rich, wide range sound
  • The subwoofer features a 5.25" long-throw bass driver for high-impact bass output
  • High performance Dolby Digital decoder amplifier with built-in 24-bit Digital-to-Analog Converter (DAC)
  • Front and rear satellite power output of 7 Watts RMS per channel

  • Subwoofer dimensions (H x W x D):  203 x 165 x 355 mm
  • Two Stereo line-in for font and rear speakers
  • Two DIGITAL in (Digital DIN and SPDIF IN-AC3)
  • Supplied with 3 meter and 5 meter speaker wires, long enough for speaker placement in corners or wall-mounting options
