    NOTE: The speaker connections above are fine for most applications. If for some reason, however, you wish to use an external power amp for any or all of the effect channels, connect the line level output jack(s) for each channel to the INPUT jacks of the external amp and connect the corresponding speaker pair to the speaker terminals of the external amp.

  • Page 25: 1-4.Adjustment

    1-4. ADJUSTMENT MAIN/CENTER/EFFECT SPEAKER LEVEL BALANCE ADJUSTMENT This operation uses an internal test-tone generator for balancing the levels of the main, center and effect speakers. 1. Depress the TEST switch on the remote control so that “TEST DOLBY” appears in the display panel to enter test mode. A hiss-like calibration signal should be heard from the left main speaker, center speaker(s), right main speaker and rear effect speakers in turn (see diagram).
  • Page 26 INPUT LEVEL ADJUSTMENT This adjustment is important for obtaining the best performance from the internal circuits of this unit. The optimum input level of this unit is pre-adjusted on the basis of the CD source level. This adjustment should be performed on all input sources in your system respectively, so that their levels match the CD source level as closely as possible.
  • Page 27 OTHER IMPORTANT SETTINGS AND ADJUSTMENTS The following seven types of settings and adjustments should be done before enjoying audio and video sources. Note that these settings and adjustments cannot be done without monitoring the display information (or the information displayed on the monitor screen).
  • Page 28 DESCRIPTIONS OF THE ITEMS 1. Selecting Center Mode (CENTER MODE NRML/WD/ PHNTM) In Normal (NRML) position, any frequency below 100 Hz will be divided between the main left and main right speakers. For this reason even a speaker smaller than the main left and right speakers can obtain a sufficient effect.
  • Page 29 3. Adjusting subwoofer level by the use of test-tone (LOW FREQ. TEST) The internal low frequency test-tone generator is useful for adjusting subwoofer level to make the subwoofer sound match the sound of other speakers in your audio system. Operating procedure 1.
  • Page 30 4. Initializing parameters on a DSP program (PARAMETER INIT) You can initialize all edited parameters on a DSP program. Note that a DSP program has two sub-programs; all parameters on both sub-programs are initialized by this operation. Operating procedure This operation cannot be done without the remote control unit.

    NOTE: Adjusting the MASTER VOLUME, BASS, TREBLE controls, etc., or selecting a sound field program has no effect on the material being recorded. NOTE: Please check the copyright laws in your country to record from records, compact discs, radio, etc. Recording of copyright material may infringe copyright laws.

  • Page 34: 2-5.Muting The Effect Sound

    3. All sound field programs 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” and “Hall B in Europe”. When the CONCERT HALL 1 program is first selected, the “Hall A in Europe”...

  • Page 35: 2-7.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 39 9. TV THEATER Mono Movie: This program is ideal for reproducing monaural video sources (old movies etc.). Monaural sounds are reproduced with strong presence by creating moderate reverberation, while conversations are oriented to the screen. Preset Parameter EFCT TRIM 0 dB DIR.
  • Page 40 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: This program is ideal for precisely reproducing the sound design of the newest movies.

  • Page 41: 2-8.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 42 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 all signals learned are long signals, it is possible that the capacity of the memory could be completely filled before all of the keys learn new functions, and so no further learning is possible.

  • Page 43: Creating Your Own Sound Fields

    This ability to create sound fields at will is exactly what Yamaha has done with the DSP system. In addition to allowing you to recreate the sound fields of famous listening environments from around the world, the DSP system allows you to create your own sound fields.
  • Page 44 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 45: 3-2.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. Refer to the “PROGRAM PARAMETER TABLE” on page 48 for a complete list of the parameters in each program. ROOM SIZE How it Affects the Sound: Changes the apparent size of the music venue.
  • Page 46 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 47 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 48 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 49 EFCT TRIM (Effect Trim) Performs fine adjustment of the level of all the effect sounds. Control Range: –3 dB to 3 dB 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.
