Cambridge Soundworks 5.1 Surround Sound DTT3500 Speakers Digital Optical Dolby Get yourself a bargain !!! Opened but never used powerful Cambridge SoundWorks DTT3500 5.1 Surround Sound system with stand alone Digital Amplifier (amplifier is not built into a subwoofer but it is a stand alone horizontal or vertical unit). It comes with 10 inch powered wooden subwoofer, 5 satellite speakers, remote control and all leads and rear satellite tripods. Technical Specification: Cambridge SoundWorks DTT3500 Digital Surround Sound Speaker System. These speakers can reproduce near cinema sound through the 5 satellites and the subwoofer. However, unlike other speakers which have the amplifier built into the subwoofer, the DTT3500 also comes with a stand alone Digital Amplifier. This, along with boosting the volume to the speakers also includes a Dolby Digital decoder that features a 24 bit Digital to Analog Converter (DAC). This DAC is also used when connecting the box to a Sound Blaster Live line of cards with Creative’s DIN connector. The decoder/amplifier box can be placed both vertically (with an included base stand) and horizontally. The front of the decoder is a removable face-plate. By default the system ships with the horizontal face-plate mounted, but a vertical face place is bundled with the system and it only takes a matter of seconds to change them around. There are 5 different face-plates included. All with cool designs that go with the theme of any room. On the front of the box you will find a number of soft touch silver buttons with the following functions along with a lot of green lights to tell you what the system settings are: A power button A button to select the Creative Multi-speaker Surround Modes (CMSS) A button to control the input mode selecting from three types of Dolby Digital/PCM inputs (Optical, Coaxial, Digital DIN or off) A button to select between two types multi-channel inputs (Line In and Digital DIN and off) A button to control the Audio Mode (LL or RR). This is mainly for VCDs where you can switch whether the sound plays on the left or right side. Useful for switching the language tracks is the VCD is dubbed in more than one language or has more than one audio track. A button to activate Dolby Pro Logic decoding on either an analogue or a digital source A button to mute the system There are also 3 dials to control the volumes of the subwoofer, center speaker and surround satellites. There is also a motorized master volume control button (indicated on the box by the blue LED) which can both be turned by hand or by the wireless remote also provided. The separate volume controls for subwoofer, rear and center speakers in addition to the master volume control allow you to have significantly louder or weaker sound from the rear and/or center than from the front or even make the rear and/or center speaker completely silent. The ports on the rear are: Optical Input (for the Xbox, PC, PS2 or any other piece of equipment that has optical output) Coaxial Analog Front and rear inputs for older sound cards or for computers with sound cards that do not support any other input method. Can be coupled with other inputs e.g. when speakers are used in conjunction with the Creative Sound Blaster range Digital DIN input. Used with the SPDIF port on the sound blaster cards to produce AC3 Sound as well as analogue sound. The main difference of using this port as opposed to the analogue ports is that the DAC of the DTT3500 is a higher quality than that of the Sound Blaster card. So the sound produced from the speakers is of a better quality since the signal is kept as digital until it leaves the electrically noisy environment of the computer case The input ports are neatly placed at the top of the box while the speaker output ports are lined up at the bottom. Also provided are little stickers to put on both the speakers and the wires so as not to cause confusion if more than one wire is accidentally pulled out. There are dozens of different sound and connection combinations, For example if you wanted to listen to some music on your PC connected via the DIN port while playing a game on a separate console connected via the optical port all you would have to do is press the button on the amplifier until the green LEDs are on both DIN and optical and voila, you can hear both sound sources at once! The remote also offers access to a speaker-test button that you can use to make sure you placed the speakers properly and connected them correctly to the box. Unfortunately the test cannot determine if you connected the box correctly to your computer or other source. There are several options to connect the DTT3500 to devices such as sound cards, hardware MPEG decoders, external DVD/VCD players, games consoles, etc Another useful feature is the ability to wall mount the speakers. Creative have also included screw holes in the back of the satellites. Location Central Scotland Delivery can be arranged at cost - buyer pays for delivery.
