DESCRIPTION OF TERMINOLOGY Dolby Pro Logic Surround: This refers to the Dolby Surround sound decoder system which is used for movies. Using 4 channels, the sound effects, dialog, sound direction, music, etc. are all reproduced more realistically. Dolby Pro Logic Surround makes the location and movement of sounds much more natural than the original Dolby Surround system. You can enjoy a realistic, powerful feeling like being at a live performance or as if you were at a movie theater or in a concert hall. In order to enjoy this effect, you need at least one pair of surround speakers and center speaker. Dolby Digital: This is the new digital surround system that was created to reproduce theater quality stereophonic Dolby Surround sound at home. Films are now recorded using the 5.1 channel system. Dolby Digital can handle the original soundtrack without modification, allowing you to enjoy the sound field created by the film maker at home.

When the sound from films recorded in Dolby Surround are reproduced, you will have the feeling of being at a live performance, as if the action is taking place right in front of you. LFE (Low Frequency Effect): This refers to the special low-frequency sound effects used in Dolby Digital recordings. When a signal containing LFE encoding is played by this unit, "LFE" will appear in the display. PCM (Pulse Code Modulation) This is a recording/transmission system used for digital audio signals. This unit can handle sampling frequencies of 32 kHz, 44.1 kHz and 48 kHz. Sub woofer: The sub woofer is a special speaker used to emphasize bass sounds. In Dolby Digital, this speaker reproduces the LFE signals as well as the low-frequency signals being sent to the front, center and surround speakers. In Dolby Pro Logic, this speaker reproduces the low-frequency signals sent to the front and center speakers. It also reproduces low frequency sounds from ordinary stereo recordings. 25 HT-DD5000(SEC) TINSE0009SJZZ
