English USING DIGITAL SOUND FIELD PROCESSOR (DSP) This unit incorporates a sophisticated, multi-program digital sound field processor. The processor allows you to electronically expand and change the shape of the audio sound field from both audio and video sources, creating a theater-like experience in your listening room. You can create an excellent audio sound field by selecting a suitable sound field program (this will, of course, depend on what you are listening to), and adding any desired adjustments. The following list gives you a brief description of the sound fields produced by each of the DSP programs. Keep in mind that most of these are precise digital recreations of actual acoustic environments. The data for these sound fields was recorded at actual locations using sophisticated sound field measurement equipment. Note The channel level balance between the left and right rear speakers may vary depending on the sound field you are listening to. This is due to the fact that most of these sound field are re-creation of actual acoustic environments. BRIEF OVERVIEW OF DIGITAL SOUND FIELD PROGRAMS No. PROGRAM 1 DOLBY PRO LOGIC ( ) Functions when the input signal is analog or PCM audio, or encoded with the Dolby Digital in 2-channel. Speaker output: main, center, rear DOLBY DIGITAL ( ) Functions when the input signal is encoded with the Dolby Digital (not in 2-channel). Speaker output: main, center, rear FEATURE Reproduces video discs, video tapes and similar sources which are Dolby Surround encoded and bear the "DOLBY SURROUND" logo. The built-in Dolby Pro Logic Surround decoder or Dolby Digital decoder precisely reproduces sounds and sound effects of a source encoded with Dolby Surround. The realization of a highly efficient decoding process improves crosstalk and channel separation and makes sound positioning smoother and more precise. 2 DOLBY PRO LOGIC ENHANCED ( ) Functions when the input signal is analog or PCM audio, or encoded with the Dolby Digital in 2-channel. Speaker output: main, center, rear DOLBY DIGITAL ENHANCED ( ) Functions when the input signal is encoded with the Dolby Digital (not in 2-channel). Speaker output: main, center, rear Reproduces video discs, video tapes and similar sources which are Dolby Surround encoded and bear the "DOLBY SURROUND" logo. This program ideally simulates the multi-surround speaker systems of the 35 mm film theater. The Dolby Surround decoding and the digital sound field processing is precisely performed without altering the original sound orientation. The surround effects produced by this sound field folds around the viewer naturally from the rear to the left and right and toward the screen. Note: If the main channel sound is considerably altered by overadjustment of BASS or TREBLE, the relationship with the rear channels may produce an unnatural effect. 3 70 mm MOVIE THEATER ( ) Functions when the input signal is analog or PCM audio, or encoded with the Dolby Digital in 2-channel. Speaker output: main, center, rear DIGITAL MOVIE THEATER ( ) Functions when the input signal is encoded with the Dolby Digital (not in 2-channel). Speaker output: main, center, rear Ideal for reproducing video discs, video tapes and similar sources which are Dolby Surround encoded and bear the "DOLBY SURROUND" logo. This program is ideal for precisely reproducing the sound design of the newest 70 mm/Dolby Digital multi-track films. The sound field is made to be similar to that of the newest movie theaters, so the reverberations of the sound field itself are restrained as much as possible. The three dimensional feeling of the sound field is emphasized, and dialog is precisely oriented on the screen. You can enjoy watching Sci-Fi, adventure movies, etc. with considerable presence. 37
