33 ENThis receiver is equipped with listening modes that allowyou to enjoy an enhanced sonic ambience with a variety ofvideo sources.In order to obtain the optimum effect from the surroundmodes, make sure to input the proper speaker settingsbeforehand. £Surround modesDolby DigitalThe Dolby Digital surround format lets you enjoy up to 5.1 channelsof digital surround sound from Dolby Digital program sources (such asLaserdisc or DVD software marked ). Compared with previ-ous Dolby surround, Dolby Digital provides even better sound quality,greater spatial accuracy, and improved dynamic range.NoteAlthough a full set of speakers (front left, right, and center, surroundleft and right, and a subwoofer) is required for true 5.1 channel DolbyDigital surround sound, this receiver lets you enjoy Dolby Digital (andDolby Surround) program sources, even if you connect only the frontspeakers.* LFE = Low Frequency Effects. This channel delivers separate non-directional bass signals to the subwoofer for more dynamic deepbass sound effects.Although only Dolby Digital soundtracks incorporate a separate lowfrequency channel, connecting a subwoofer will also improve deepbass performance in the other surround modes.The indication “LFE” appears in the display when a signal is beinginput for this channel.“DTS”, “DTS-ES Extended Surround”and “Neo:6” are trademarks of DigitalTheater Systems, Inc.Manufactured under license from Dolby Laboratories. “Dolby”, “ProLogic”, “Surround EX” and the double-D symbol are trademarks ofDolby Laboratories.“Circle Surround II and the ® symbol are trademarks of SRS Labs,Inc.

Used underauthorization.Dolby Digital EXDolby Digital EX is an extension of Dolby Digital technology, DolbyDigital EX creates six full-bandwidth output channels from 6.1-channelsources. This is done using a matrix decoder that derives threesurround channels from the two in the original recording.This is achieved by using three different surround signals, LeftSurround , Right Surround, and Back Surround, each driving its ownarray of speakers. Think of it as adding a center channel for the rearspeakers, which give more diffuse and natural surround effect, evenif you wanted the ability to completely encircle the audience withsound, positioning sound effects exactly where they wolud be heardin real life. For best results, Dolby Digital EX should be used withmovie soundtracks recorded with Dolby Digital Surround EX whichcontain a digital flag that will automatically activate this feature.However, for titles released prior to late 2001, this feature has to beactivated manually.NoteAlthough a full set of speakers (front left, right, and center, surroundleft and right, surround back left and right, and a subwoofer) isrequired for true 6.1 channel Dolby Digital surround EX sound, thisreceiver lets you enjoy Dolby Digital (and Dolby Surround) programsources, even if you connect only the front speakers.* LFE = Low Frequency Effects.

This is achieved with an intelligent, built-infeedback logic design, a matrix surround decoding and the decodingof stereo, full bandwidth surround outputs. The PRO LOGIC II modesprogrammed into this receiver are “MOVIE”, “MUSIC” and “PROLOGIC”. The “MOVIE” mode of the PRO LOGIC II has presetcharacteristics to produce a calibrated, high-level surround soundplayback while the “MUSIC” mode has user-adjustable characteris-tics to offer the three optional controls, like “Dimension”, “CenterWidth” and “Panorama” modes to allow optimization of the soundfieldsas desired. The “Dimension” control allows the user to graduallyadjust the soundfield either towards the front or towards the rear; the“Center Width” control allows various adjustment of the left-center-right speakers’ balance; the “Panaroma” mode extends the frontstereo image to include the surround speakers for an exciting “wrap-around” effect with side wall imaging.Surroundspeakers(L, R)Center speakerSubwoofer (SW)*Front speakers (L, R)Center speakerSubwoofer(SW)*Surroundspeakers(L, R) Surroundback speakers(L, R)Front speakers (L, R)Center speakerSubwoofer (SW)Surroundspeakers(L, R)Front speakers (L, R)* Optional in this mode.Ambience effects* Optional in this mode.
