Yamaha DTX-CS870 Home theatre system DTXCS870 High Definition Multimedia Interface (HDMI) is the first and only digital interface to combine uncompressed high-definition video, multi-channel audio and intelligent format and command data in a single digital interface. HDMI switching, providing the most advanced method of delivering high quality video signals to a home theater system to enable the reproduction of DVD and satellite TV sources with HD quality. Compatible with the HDMI version 1.1 format, it can also decode digital audio signals from sources such as DVD-Audio, CD, Dolby Digital and DTS. Easier Than Changing A Tire Yamaha changers give you the benefits of extended playing time and direct selection from all discs. And with PlayXchange, you can change discs while the current one continues to play. You don't have to interrupt the music to change a disc and you're not limited to changing only one disc at a time. Have No Fear, Super Audio CD Is Here DVD Players that support Super Audio CD use a technology called Direct Stream Digital (DSD) to convert music into a digital signal that can be stored on a disc. Compared to the traditional PCM method (the technology used for CD), DSD offers a much higher resolution by following more closely the original waveform of music. With a frequency response of over 100kHz and a dynamic range over 120dB across the audible frequency range—some 64 times higher resolution then CD—Super Audio CD offers music reproduction that reveals details you just can?t hear on a normal CD.

DivX: MP3's Kindred Spirit DivX is the video compression codec developed by DivX Networks and based on the MPEG-4 compression format. Its balance of high video quality and low bit rate has made it very popular and quickly established it as the best home video format thus far. The ability to play it on newer DVD models continues to add to its popularity as DivX Networks advances its support to many new household products. This compression technology has the potential for expanding the ways we view video media in much the way MP3 has given us many new ways to listen to music. Don't Let Impedance Be An Impediment Advanced Yamaha Active Servo Technology (Advanced YST) is a unique system in which the speaker and amplifier work together to cancel out impedance so the speaker unit has a perfectly linear motion. Advanced YST helps to ensure the highest levels of sound pressure and overall performance.
