    3. All sound field programs except CHURCH have two “sub- programs” (see “2-7. DESCRIPTIONS OF THE SOUND FIELD PROGRAMS”). The sub-programs are selected using the Parameter +/– keys on the remote control unit. The CONCERT HALL 1 program, for example, contains the sub-programs “Hall A in Europe”...
  • Page 35: Descriptions Of The Sound Field Programs

    2-7. 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 36 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 37 7. ENTERTAINMENT Stadium: This program gives you long delays between direct sounds and effect sounds, and extraordinarily spacious feel of a large stadium. Disco: This program recreates the acoustic environment of a lively disco in the heart of a very lively city. The sound is dense and highly concentrated.
  • Page 38 9. CONCERT VIDEO 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.You...
  • Page 39 11. MOVIE THEATER Ideal for reproducing video discs, video tapes and similar sources which are Dolby Surround encoded and bear the “DOLBY SURROUND” logo. 70 mm Adventure: This program is ideal for precisely reproducing the sound design of the newest movies. The sound field is made according to the design of the newest movie theaters, so the reverberations of the sound field itself are restrained as...
  • Page 40: 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 41 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.
  • Page 42: 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 43 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 44: Descriptions Of The Digital Sound Field Parameters

    3-2. 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 45 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 46 DIR. ENHANCEMENT (Directional Enhancement) This circuit emphasizes the position of sound. If this circuit is activated, the unity constituent of the input left and right channels (those signals which are common to the left and right channels) will be output from the center speaker, and the disparity constituent of the left and right signals (the difference between the left and right channels) will be output from the surround speakers.
  • Page 47: Troubleshooting

    TROUBLESHOOTING POSSIBLE CAUSE PROBLEM AC cord not properly plugged in. Power does not come on. Bad cable connection. Hum. Bad or incorrect input connection. No sound. Incorrect input source selection. The EFFECT switch is set off. No sound from the effect speakers. The DOLBY PRO LOGIC program is being used with material not encoded with Dolby Surround.
