FEATURES 1. Digital Surround Sound Decoding Featuring dual 32 bit high speed DSP processors, operating entirely in digital domain, surround sound from digital sources such as DVD, DTV and satellite are faithfully re-created. 2. Dolby Digital Using advanced digital processing algorithms, Dolby Digital provides up to 5.1 channels of wide- range, high fidelity surround sound. Dolby Digital is the default digital audio delivery system for North American DVD and DTV, and is available on laser discs as well as some digital satellite direct- to-home services. 3. DTS I Digital Theater Systems) DTS provides up to 5.1 channels of wide-range, high fidelity surround sound, from sources such as laser disc, DVD and specially-encoded music discs. 4. Lucasfilm Home THX Ultra2 Certified Home THX is the unique collaboration between Lucasfilm Ltd. and audio equipment manufacturers. THX Ultra2 certification is the highest performance level, and provides a rigorous set of performance standards, along with proprietary surround sound post-processing technologies, designed to enhance the surround soundtrack playback experience in the home theater. In addition to improvements to the power amplifier with respect to previous THX Ultra standards, two surround modes have been added: the THX Ultra2 Cinema mode and the THX Music mode. 5. THX Surround EX The AVC-A1SR is fully compatible with THX Surround EX the latest surround format. 6. DTS-ES Extended Surround and DTS Neo:6 The AVC-A1SR is compatible with DTS-ES Extended Surround, a new multi-channel format developed by Digital Theater Systems Inc. The AVC-A1SR is also compatible with DTS Neo:6, a surround mode allowing 6.1-channel playback of regular stereo sources. 7. DTS 96/24 compatibility The AVC-A1SR is compatible with sources recorded in DTS 96/24, a new multi-channel digital signal format developed by Digital Theater Systems Inc. DTS 96/24 sources can be played in the multi-channel mode on the AVC-A1 SR with high sound quality of 96 kHz/24 bits or 88.2 kHz/24 bits. 8. Dolby Pro Logic Π decoder Dolby Pro Logic H is a new format for playing multichannel audio signals that offers improvements over conventional Dolby Pro Logic. It can be used to decode not only sources recorded in Dolby Surround but also regular stereo sources into five channels (front left/right, center and surround left/right). In addition, various parameters can be set according to the type of source and the contents, so you can adjust the sound field with greater precision. 9. Wide screen mode for a 7.1 -channel sound even with 5.1 -channel sources DENON has developed a wide screen mode with a new design which recreates the effects of the multi surround speakers in movie theaters. The result is 7.1-channel sound taking full advantage of surround back speakers, even with Dolby Pro Logic or Dolby Digital/DTS 5.1-channel signals. 10. Dual Surround Speaker Mode Provides for the first time the ability to optimize surround sound reproduction using two different types of surround sound speakers as well as two different surround speaker positions: (1) Movie Surround Motion picture soundtracks use the surround channel(s) to provide the ambient elements of the acoustic environment they want the audience to realize. This is best accomplished by the use of specially-designed surround speakers that offer a wide diffusion pattern (bipolar dispersion) or by using surround speakers that provide broad dispersion with a minimum of on-axis localization (dipolar dispersion). Sidewall mounting (closer to the ceiling) of the surround speakers provides the greatest envelopment, minimizing localization of direct sound from the speakers. (2) Music Surround With full range discrete surround channels, as well as three discrete full range front channels, digital formats such as Dolby and DTS offer thrilling surround sound music listening. Producers of multi-channel discrete digital music recordings almost always favor the use of direct radiating (monopolar) surround speakers, placed in the rear corners of the room, since that is how they configure their studios during the mixing/creation process. The DENON AVC-A1SR provides the ability to connect two different sets of surround speakers, and place them in the appropriate locations in your home theater room, so that you can enjoy both movie soundtracks and music listening, with optimum results and no compromise. 11. Multi-zone control The AVC-A1 SR is equipped with two sets of multizone outputs allowing a source other than the one currently being played to be selected. (1) Multi-zonel These are level adjustable pre-outputs. (A fixed output level can also be selected.) The video signals of the input source selected with the multi-zonel selector are output. (2) Multi-zone2 Fixed level pre-out outputs allowing independent selection of the input source. 12. Component Video Switching The AVC-A1SR provides 3 sets of component video (Y, R-Y, B-Y) inputs for the DVD, TV and DBS/SAT inputs, and one set of component video outputs to the television, for superior picture quality. The AVC-A1 SR is also equipped with a function for up-converting composite video or S-Video signals to component video signals. 13. Video Select Function Allow you to watch one source (visual) while listening to another source (audio). 14. Seven Identical Power Amplifiers Featuring discrete high current power transistors, the power amp section is THX Ultra certified for top performance with the widest range of speaker systems. Rated at 170 watts into 8 Ω/ohms, the amp channels feature additional low impedance drive capability. 15. Future Sound Format Upcp-ade Capability via Eight Channel Inputs & Outputs For future multi-channel audio format(s), the AVC- A1SR is provided with 7.1 channel (seven mainchannels, plus one low frequency effects channel) inputs, along with a full set of 7.1 channel pre-amp outputs, controlled by the 8 channel master volume control. This assures future upgrade possibilities for any future multi-channel sound format. A/D converters are provided for each channel for digital down-mixing compatibility. 16. Dolby Headphone Compatibility This is a three-dimensional sound technology developed jointly by Dolby Laboratories and Lake Technology Ltd. of Australia for achieving surround sound using regular headphones. 17. DENON Unk This terminal can be used to connect a Denon DVD player for high quality digital multichannel playback. 18. Auto Surround Mode This function stores the surround mode last used for an input signal in the memory and automatically sets that surround mode the next time that signal is input. 19. Audio Delay This is a function for delaying the audio signal with respect to the video signal. (0 to 200 msec) 20. Setup Lock This is a function that locks the system setup and surround parameter settings, etc., so that they cannot be changed.
