  • Page 43 6. CINEMA EQ (Adjusting the tonal balance of speakers) It is difficult to balance tonal quality of the main, center, front effect and rear effect speakers, because they may be different in type and size, and their setting positions and heights are also different. The built-in CINEMA Equalizer enables you to balance tonal quality of the speakers easily by adjusting tonal quality of the main/center, front effect and rear effect channels individually.

  • Page 56: Descriptions Of The Sound Field Programs

    DESCRIPTIONS OF THE SOUND FIELD PROGRAMS The following list gives brief descriptions 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 them was recorded at the locations described using sophisticated sound field measurement equipment.
  • Page 57 3. CONCERT HALL 3 Hall E in Europe: A classic large shoe-box type concert hall with approximately 2200 seats. It has a circular stage and seats located behind the stage. Live Concert: A large round concert hall with a rich surround effect.
  • Page 58 7. CONCERT VIDEO 1 Classical/Opera: This program provides excellent depth of vocals and overall clarity, restraining excessive reverberation. For opera, the orchestra pit and the stage are ideally combined, letting you feel a full presence sound. The rear surround side of the sound field is relatively moderated, however, it reproduces beautiful sound by the use of the data of a concert hall.
  • Page 59 9. TV THEATER Mono Movie: This program is for reproducing monaural video sources (old movies etc.). Monaural sounds are reproduced with much presence by the front presence side of the sound field and optimum reverberation effect. The use of the center speaker makes conversations more audible, obtaining a pleasant mix of conversations and picture.
  • Page 60 11. MOVIE THEATER 2 Ideal for reproducing video discs, video tapes and similar sources which are Dolby Surround encoded and bear the “DOLBY SURROUND” logo. 70 mm Adventure (When the Dolby Pro Logic Surround is decoded): AC-3 Adventure (When the Dolby Surround AC-3 is decoded): This program is ideal for precisely reproducing the sound design of the newest 70 mm/AC-3 multi-track films.

  • Page 62: Creating Your Own Sound Fields

    In each program, those parameters are preset with values precisely calculated by Yamaha to create the sound field unique for the program. It is recommended to use DSP programs without changing values of parameters, however, this unit also allows you to create your own sound fields.
  • Page 63 In addition to the “TYPE” parameter which selects the sub- programs within each sound field program (e.g. “Hall A in Europe” and “Hall B in Europe” for program 1, “CONCERT HALL 1”), each program also has a set of parameters that allow you to change the characteristics of the acoustic environment to create precisely the effect you want.

  • Page 64: Descriptions Of The Digital Sound Field Parameters

    DESCRIPTIONS OF THE DIGITAL SOUND FIELD PARAMETERS Not all of the following parameters are found in every program. ROOM SIZE How it Affects the Sound: Changes the apparent size of the music venue. The larger the value, the larger the simulated room will sound. What it Does: Adjusts the timing between the early reflections.
  • Page 65 LIVENESS How it Affects the Sound: This parameter changes the apparent reflectivity of the walls in the hall. The early reflections from a sound source will lose intensity (decay) much faster in a room with acoustically absorbent wall surfaces than in one which has mostly reflective surfaces. A room with highly reflective surfaces in which the early reflections decay slowly is termed “live”, while a room with absorbent characteristics in which the reflections decay rapidly is termed “dead”.
  • Page 66 REV. DELAY (Reverberation Delay) This parameter sets the time difference between the beginning of the direct sound and the beginning of the reverberation sound. The larger the value, the later the reverberation sound will begin. A later reverberation sound makes you feel like the space of the acoustic environment has become larger.
  • Page 67 P. INIT. DLY (Presence Initial Delay) Adjusts the delay between the direct sound and the first reflection on the presence side of the sound field. The larger the value, the later the first reflection begins. Control Range: 1 – 49 milliseconds P.

  • Page 68: Remote Control Learning Function

    The remote control unit, in addition to controlling the most commonly used functions of the main unit and other connected Yamaha audio and video equipment, has a sophisticated “learning” function that allows it to control other equipment in your system or other household appliances equipped with infrared remote control receivers.
  • Page 69 NOTE: The originally preset function of a key is still available in the USER position if the key does not learn a new function. NOTE: If there is no more room in the memory area for a function to be learned, the TRANSMIT/LEARN indicator will flash on and off eight times.
