RDS tuners with Radiotext can receive short messages which might include information about the presenter, station or programme you are listening to. For example, BBC Radio 1's RadioTEXT usually gives information about the presenter and programme, whereas Classic FM gives information which includes a web address for the station. The information will scroll across the display on a home tuner.
7 channel equal power output
7 channel equal power is a feature used in Denon Amplifiers with the means of connecting 7 speakers independantly which do not require separate power amps connected via the pre-outs. This feature compliments Dolby Digital EX and DTS ES sound modes. Allowing you to connect the second 'surround back' speaker, which compliments the surround back speaker initially there for 6.1, straight off the main amplifier without adding a power amplifier to support 7.1 surround formats. The amplifier has built in separate internal amplifiers to power each channel independently, this system ensures that the 6 major channels Front Left, Front Right, Center, Surround Left, Surround right, Surround Back left and Surround Back right. Thus allowing you to enjoy the same high power output, giving a balanced and truly high-impact surround-sound environment.
The sound from movie sources recorded in Dolby Digital, DTS, or other formats emphasizes high-frequency range due to a theater’s front speakers being placed behind the movie screen. If this sound is reproduced in the home theater without correction, the high-frequency range is too strong. Denon amplifiers feature a Cinema Equalizer to correct these high-frequency components so that the sound is clearer and easier to listen to. (For Dolby Digital, Dolby Pro Logic II, and DTS surround modes.)
Dolby Digital EX
In a movie theater, film soundtracks that have been encoded with Dolby Digital surround EX technology are able to reproduce an extra channel which has been added during the mixing of the program. This channel, called Surround Back, places sounds behind the listener in addition to the currently available front left, front center, front right, surround right, surround left and subwoofer channels. The additional channel provides the opportunity for more detailed imaging behind the listener and brings more depth, spacious ambience and sound localization then ever before. Dolby Digital EX is not available in the system without surround back speaker(s).
Dolby Pro Logic II
The Dolby Pro Logic ll decoder reproduces dynamic 5.1-channel surround sound from 2-channel sources such as TV, videos and CDs. Dolby Pro Logic ll uses matrix-decoding technology that has been dramatically improved over Pro Logic. With Pro Logic ll, for instance, the Surround channels are in stereo instead of just mono with Pro Logic, and playback covers the full frequency range instead of just up to 7kHz with Pro Logic. These improvements let you enjoy a wide variety of 2-channel sources with the exciting effects of 5.1-channel surround sound. In Dolby Pro Logic ll, there is a Movie mode (*1) that creates a sound field for movies, a Music mode that does the same for music, and a Pro Logic emulation feature that reproduces sound effects in the way that conventional Pro Logic does.
Dolby Pro Logic II Music: The music mode creates a rich and enveloping surround ambience delivered to the subwoofer, optimizing the visceral of planned rear effects. This mode can only be used with 2-channel audio sources.
Dolby Pro Logic II Cinema: The Cinema mode is optimized for movies or programs with Dolby Surround soundtracks. This mode is also appropriate for use with video game.
Dobly Pro Logic II Game: The game mode was implemented to ensure that the bass impact from pure surround effects are fully delivered to the subwoofer, optimizing the visceral of panned rear effects. This mode can only be used with 2-channel audio sources.
Dolby Pro Logic IIx
Dolby Pro Logic IIx is an extension of Dolby Pro Logic II technology. This highly sophisticated algorithm processes native stereo and 5.1 channel content to produce 6.1 or 7.1 output channels. And Dolby Pro Logic IIx is not available in the system without surround back speaker(s).
Dolby Pro Logic IIx Music: The music mode creates a rich and enveloping surround ambience delivered to the subwoofer, optimizing the visceral of planned rear effects. This mode can only be used with 2-channel audio sources.
Dolby Pro Logic IIx Cinema: The Cinema mode is optimized for movies or programs with Dolby Surround soundtracks. This mode is also appropriate for use with video game.
Dolby 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, center, surround left, surround right and an additional channel exclusively reserved for additional deep bass sound effects (the Low Frequency Effects - LFE - channel, also called the ".1" channel, containing bass frequencies of up to 120Hz).
Unlike the analog Dolby Pro Logic format, Dolby Digital's main channels can all contain full range sound information, from the lowest bass, up to the highest frequencies - 22kHz. The signals within each channel are distinct from the others, allowing pinpoint sound imaging and Dolby Digital offers tremendous dynamic range from the most powerful sound effects to the quietest, softest sounds, free from noise and distortion.
DTS 96/24 allows high-quality 5.1 channel sound playback with full-quality, full-motion video. DTS 96/24 allows both digital audio output and video output from your existing DVD player and is backward compatible with existing DTS decoders for normal DTS 5.1 playback. DTS 96/24 actually exceeds the resolution of most film soundtrack masters to date, and will initially apply mainly to high quality DTS music DVD discs.
A data compression method developed by Digital Threater Systems that takes six channels of audio (5.1) and folds them into a single digital bitstream. This differs from Dolby Digital in that the data rate is a somewhat higher 1.4 Mbs, which represents a compression ratio of about 4 to 1.In order to take advantage of this DVD feature, a DTS decoder is required. DTS decoders are installed internally in Denon players and A/V recievers.
DTS-ES Discrete/Matrix 6.1
DTS-ES Extended Surround is a multi-channel digital signal format develpoed by Digital Theater Systems Inc. While offering high compatibility with the conventional DTS Digital Surround format, DTS-ES greatly improves the 360 degree surround impression and space expression thanks to further expanded surround signals. This format has been used professionally in movie theaters since 1999.
In addition to the 5.1 surround channels, DTS-ES also offers the surround back channel for surround playback with a total of 6.1 channels. DTS-ES includes two signal formats with different surround signal recording methods, as DTS-ES Discrete 6.1 and DTS-ES Matrix 6.1.
DTS-ES Discrete 6.1
DTS-ES Discrete 6.1 is the newest recording format. With it, all 6.1 channels (including the SB channel) are recorded independently using a digital discrete system. The main feature of this format is that because the SL, SR and SB channels are fully independent, the sound can be designed with total freedom and it is possible to achieve a sense that the acoustic images are moving about freely among the background sounds surrounding the listener from 360 degrees. Though maximum performance is achieved when sound tracks recorded with this system are played using a DTS-ES decoder, when played with a conventional DTS decoder the SB channel signals are automatically
down-mixed to the SL and SR channels, so none of the signal components are lost.
DTS-ES Matrix 6.1
With this format, the additional SB channel signals undergo matrix encoding and are input to the SL and SR channels beforehand. Upon playback they are decoded to the SL, SR and SB channels. The performance of the encoder used at the time of recording can be fully matched using a high precision digital matrix decoder developed by DTS, thereby achieving surround sound more faithful to the producer’s sound design aims than with conventional 5.1- or 6.1-channel systems. In addition, the bit stream format is 100% compatible with conventional DTS signals, so the effect of the Matrix 6.1 format can be achieved even with 5.1-channel signal sources. Of course it is also possible to play DTS-ES Matrix 6.1 encoded sources with a DTS 5.1-channel decoder.
Radio Data System
Radio Data System for VHF/FM broadcasting.
The developers aimed at making radio receivers very user-friendly. Listeners should be able to see the programme service name (PS) on an eight character alpha-numerical display and the transmitter frequency information, as displayed on non-RDS radios, is then only used in the background by an RDS radio. The tuner is able to choose the transmitter frequency, among a number of alternatives, that gives the best quality reception.
Travel information with RDS is currently possible using the Travel Programme (TP) and Travel Announcement (TA) flags.
Once a radio is tuned to a programme service broadcast within a network, using the RDS feature Enhanced Other Networks (EON), additional data about other programmes from the same broadcaster will be received. This enables the listener, according to their choice, to have the radio operating in an automatic switch-mode for travel information or a preferred Programme Type (PTY, e.g. News).
Another feature of RDS is accurate Clock-Time, displaying the time/date when selected.
