1. Dolby Digital Using advanced digital processing algorithms, Dolby Digital provides up to 5.1 channels of widerange, high fidelity surround sound. Dolby Digital is the default digital audio delivery system for DVD and North American DTV. 2. Dolby Pro Logic IIx compatibility Dolby Pro Logic IIx furthers the matrix decording technology of Dolby Pro Logic II to decode audio signals recorded on two channels into up to 7.1 playback channels, including the surround back channel. Dolby Pro Logic IIx also allows 5.1- channel sources to be played in up to 7.1 channels. The mode can be selected according to the source. The Music mode is best suited for playing music,the Cinema mode for playing movies, and the Game mode for playing games. The Game mode can only be used with 2-channel audio sources. 3. Dolby Pro Logic II Game mode compatibility In addition to the previously offered Music and Cinema modes, the AVR-1905 also offers a Game mode optimum for games. 4. DTS (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. 5. DTS-ES Extended Surround and DTS Neo:6 The AVR-1905 can be decoded with DTS-ES Extended Surround, a multi-channel format developed by Digital Theater Systems Inc. The AVR-1905 can be also decoded with DTS Neo:6, a surround mode allowing 6.1 channels playback of regular stereo sources. 6. DTS 96/24 compatibility The AVR-1905 can be decoded with sources recorded in DTS 96/24, a multi-channel digital signal format developed by Digital Theater Systems Inc. DTS 96/24 sources can be played in the multichannel mode on the AVR-1905 with high sound quality of 96 kHz/24 bits or 88.2 kHz/24 bits. 7. Future Sound Format Upgrade Capability via Eight Channel Outputs For future multi-channel audio format(s), the AVR- 1905 is provided with 5.1 channel (five main channels, 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. 8. Front input Terminal The unit is equipped with a Front Input connector for the convenient connection of a video camera or other equipment. 9. Video Conversion Function The AVR-1905 is equipped with a function for converting the signals input to the video input connector and S-Video input connector. With this function, the AVR-1905’s monitor out connector and the monitor (TV) can be connected with video pin-plug cords or an S-Video connection cord. 10. Component Video Switching In addition to composite video and “S” video switching, the AVR-1905 provides 3 sets of component video (Y, PB/CB, PR/CR) inputs, and one set of component video outputs to the television, for superior picture quality. 11. 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. 12. Preset Memory Tuning 56-Station AM/FM Random Preset Memory tuning. 13. On Screen Diaplay Troublesome operations such as adjusting the delay time and other parameters according to the listening environment are greatly simplified. The various parameters can be set simply by selecting the graphic displayed on the monitor screen according to the listening room’s system environment.
