Dolby DigitalDolby Digital is the multi-channel digital signal format developed by Dolby Laboratories. Dolby Digital consists of up to “5.1” channels – front left,front right, centre, surround left, surround right and an additional channel exclusively reserved for additional deep bass sound effects. (The LowFrequency Effects (LFE) channel containing bass frequencies of up to 120Hz). Unlike the analogue Dolby Pro Logic format, Dolby Digital’s channelscan all contain full range sound information, from the lowest bass, up to the highest frequencies (22kHz).The signals within each channel aredistinct from the others, allowing pinpoint sound imaging, and Dolby Digital offers tremendous dynamic range from the most powerful soundeffects to the quietest, softest sounds, free from noise and distortion.2. Dolby Pro Logic IIDolby Pro Logic II is a new multi-channel playback format developed by Dolby Laboratories using feedback logic steering technology and offeringimprovements over conventional Dolby Pro Logic circuits. Dolby Pro Logic II can be used to decode not only sources recorded in DolbySurround but also regular stereo sources into five channels (front left, front right, centre, surround left and surround right) to achieve surroundsound.Whereas with conventional Dolby Pro Logic the surround channel playback frequency band was limited, Dolby Pro Logic II offers a widerband range (20Hz to 20kHz or greater). In addition the surround channels were monoaural (the surround left and right channels were the same)with previous Dolby Pro Logic, but with Dolby Pro Logic II they are played as stereo signals.3. Dolby SurroundThese are sources in which three or more channels of surround have been recorded as two channels using Dolby Surround encoding technology.Dolby Surround is used for the sound tracks of movies recorded on DVDs, LDs and video cassettes to be played on VCRs, as well as for thestereo broadcast signals of FM radio,TV, satellite broadcasts and cable TV. Decoding these signals with Dolby Pro Logic makes it possible toachieve multi-channel surround playback.The signals can also be played on ordinary stereo equipment, in which case they provide normal stereosound.There are two types of DVD Dolby SURROUND recording signals. 1) 2-channel PCM stereo signals 2) 2-channel Dolby Digital signals.The KEF Instant Theatre is manufactured under license from Dolby Laboratories. “Dolby”, “Pro Logic” and the double-D symbol are trademarksof Dolby Laboratories.Digital Theatre Surround (also called simply DTS) is a multi-channel digital signal format developed by Digital Theatre Systems. DTS offers thesame “5.1” playback channels as Dolby Digital (front left, front right and centre, surround left and surround right) as well as the stereo 2-channelmode.The signals for the different channels are fully independent, eliminating the risk of deterioration of sound quality due to interferencebetween signals and crosstalk etc. DTS features a relatively higher bit rate as compared to Dolby Digital (1234 kbps for CDs and LDs, 1536 kbpsfor DVDs) so it operates with a relatively low compression rate. Because of this the amount of data is great, and when DTS playback is used inmovie theatres, a separate CDROM synchronised with the film is played.With LDs and DVDs, there is of course no need for an extra disc;the pictures and sound can be recorded simultaneously on the same disc, so the discs can be handled in the same way as discs with otherformats.There are also music CDs recorded in DTS.These CDs include 5.1-channel surround signals (compared to two channels on currentCDs).They do not include picture data, but they offer surround playback on CD players that are equipped with digital outputs (PCM type digitaloutput required). External DTS CD bitstreams coming in on the optical SPDIF audio CBL input of the KEF Instant Theatre will not be decoded bythe KEF Instant Theatre system. DTS surround playback offers the same intricate, grand sounds as a movie theatre, right in your own listeningroom. “DTS” and “DTS Digital Surround” are registered trademarks of Digital Theatre Systems Inc.The KEF Instant Theatre incorporates copyright protection technology that is protected by U.S. patents and other intellectual property rights.Use of this copyright protection technology must be authorised by Macrovision, and is intended for home and other limited viewing uses onlyunless otherwise authorised by Macrovision.
