SETUP & ADJUSTMENT Installing the Remote Control Unit Batteries Unpacking Since the remote control unit will be used for many of this unit’s control operations, you should begin by installing the supplied batteries. If you haven’t already done so, carefully remove this unit and its accessories from the box and wrapping material.You should find the unit itself and the following accessories. Batteries English 1-1. GETTING STARTED 1.
● When you notice that remote control operation has become erratic, or the distance from which the remote control will function has decreased, it’s time to replace the batteries. Always replace all batteries at the same time. ● Make sure that the YPC/USER/LEARN switch on the remote control unit is set to the YPC or USER position for normal operation. ● This remote control uses an advanced, highly directional infrared beam.
Dolby Pro Logic Surround + DSP The Dolby Pro Logic Surround Decoder program lets you experience the dramatic realism and impact of Dolby Surround movie theater sound in your own home. Dolby Pro Logic gets its name from its professional-grade steering logic circuitry, which provides greater effective channel separation for a much higher degree of realism than the “passive” Dolby Surround circuits found in today’s typical home audio/video equipment.
Video superimpose Open/close the control door If you connect your video cassette recorder, video disc player, video monitor, etc. to this unit, you can take advantage of this unit’s capability to display program titles, parameter data and information about other various settings and adjustments on your video monitor’s screen. This information will be superimposed over the video image. When it is not necessary to operate controls inside the control door, close the door.
Use of the Center Dialog Speaker Is Recommended This unit has been designed to provide the best sound field quality with a full seven-speaker system setup, using two extra pairs of effect speakers to generate the sound field plus one center speaker for dialog, when using Dolby Pro Logic Surround decoding. We therefore recommend that you use a seven-speaker setup.
Four Possible Types of Speaker System Configurations Recommended 8 4 Speaker System 5 Speaker System 6 Speaker System 7 Speaker System Simplest system. Good for Audio/Video sources and Dolby Pro Logic Surround. Good for sound fields from 2-channel stereo sources. This is the recommended speaker system, providing the best sound effects. You can enjoy widely diffused sound by only adding two additional speaker units at the rear. With sound field programs No. 8 through No.
English Speakers and Speaker Placement Your full seven-speaker system will require three speaker pairs: the MAIN SPEAKERS (your normal stereo speakers), the FRONT EFFECT SPEAKERS and the REAR EFFECT SPEAKERS, plus the CENTER SPEAKER.You may also be using a subwoofer. You will probably use your present stereo speakers as the MAIN SPEAKER pair. The front effect and rear effect do not need to be equal with the MAIN SPEAKERS, although the center speaker should be as close as possible.

F Low Pass Jack When using a subwoofer, connect its amplifier input to this jack. Frequencies below 200 Hz from the left main, right main and center channels are output to this jack. G Center Out Jack Center-channel line output. Not connected when the built-in amplifier is used. Can be connected to input jack of an external power amplifier to drive the center speaker. H Voltage Selector (General Model only) Be sure to set to the line voltage in your area before applying power.
GENERAL INSTRUCTIONS FOR CONNECTIONS There are several switches and controls on the rear panel that you’ll have to check before operating your system, and it’s a good idea to do it before you connect cables. Locate the MAIN LEVEL slide switch (3) and FRONT MIX slide switch (D). Make sure the MAIN LEVEL switch is set to “0 dB” and the FRONT MIX switch is set to “OFF” for 7 or 6 speaker driving. Make sure that you have the left (L) and right (R) channels correctly connected.
CONNECTING AUDIO/VIDEO SOURCE EQUIPMENT TO THIS UNIT * If you have YAMAHA components numbered as 1, 2, 3, etc. on the rear panel, connections can be made easily by making sure to connect the output (or input) terminals of each component to the same-numbered terminals of this unit.
If your video cassette recorder, video disc player, etc. and your monitor are equipped with “S” (high-resolution) video terminals, connect them to this unit’s S VIDEO jacks, and connect this unit’s S VIDEO MONITOR OUT jack to the “S” video input of your monitor. Otherwise, connect the composite video jacks from your video cassette recorder, video disc player, etc. to the VIDEO jacks of this unit, and connect this unit’s VIDEO MONITOR OUT jack to the composite video input of your monitor.
For connecting with a monitor TV that uses a 21 pin connector for input (for Europe and U.K. models) CONNECTING SPEAKER SYSTEMS Connect the SPEAKERS terminals to your speakers with wire of the proper gauge, cut as short as possible. If the connections are faulty, no sound will be heard from the speakers. Make sure that the polarity of the speaker wires is correct, that is, + and – markings are observed. If these wires are reversed, the sound will be unnatural and will lack bass.
Connect the MAIN speakers to the MAIN speaker output terminals of this unit. Make sure that the jumper bars between the PRE OUT and MAIN IN jacks on the rear panel are in place. It is also possible to use an external power amplifier if more power is desired. In this case, remove the jumper bars and connect the PRE OUT jacks to the INPUT jacks of a stereo power amplifier with a stereo pin cable—making sure to connect the left and right channels correctly.
CONNECTING THE EFFECT SPEAKERS AND THE CENTER SPEAKER(S) TO THIS UNIT Center speaker Connect the FRONT effect speakers to the FRONT effect speaker output terminals of this unit. If the FRONT effect speakers are not used, the FRONT MIX switch should be set to “ON”. Front effect speaker L Center speaker Front effect speaker Center speaker R Connect the REAR effect speakers to the REAR effect speaker output terminals of this unit.

NOTE: Please check the copyright laws in your country to record from records, compact discs, radio, etc.
3. All sound field programs except CHURCH have two “subprograms” (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” sub-program will be selected and displayed on the front panel.
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. * The channel level balance between the left rear effect speaker and the right rear effect speaker may vary depending on the sound field you are listening to.
3. CONCERT HALL 3 5. ROCK CONCERT 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. Pronounced reflections from all directions emphasize the extension of sounds.You will experience the sound field with a great deal of presence sitting at about the center position near the stage. This sound field is also effective for karaoke.
8. TV THEATER Stadium: This program gives you long delays between direct sounds and effect sounds, and extraordinarily spacious feel of a large stadium. Drama: The data of the sound field of a relatively narrow space is used for the front presence side. A moderately sized spatial sound field without excessive sound extension and reverberations gives reality to the characters in a drama. The data of the sound field of an opera house is used for the rear surround side.
9. CONCERT VIDEO 36 10. VIDEO THEATER 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 will not be tired from long watching of an opera.
12. DOLBY PRO LOGIC SURROUND Ideal for reproducing video discs, video tapes and similar sources which are Dolby Surround encoded and bear the “DOLBY SURROUND” logo. Reproduces 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.
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.
Erasing All Learned Functions 1. Set the YPC/USER/LEARN switch to “LEARN”. 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. In this case, even if some keys are not occupied with functions from other remote control units, no further learning is possible. The function learned by any key can be easily changed by repeating the learning process with a different function.
CREATING YOUR OWN SOUND FIELDS 3-1. SELECTING AND EDITING PROGRAM PARAMETERS WHAT IS A SOUND FIELD? In order to explain the impressive functions of the DSP system, we need to first understand what a sound field really is. What really creates the rich, full tones of a live instrument are the multiple reflections from the walls of the room. In addition to making the sound “live”, these reflections enable us to tell where the player is situated, and the size and shape of the room in which we are sitting.
1. With the desired program selected, press the Parameter Select (▼ ▼) key on the remote control unit once. This will recall the next parameter after the program type. In the case of the CONCERT HALL 1 program, for example, this would be the INIT. DLY parameter. You can continue pressing the Parameter Select (▼ ▼) key to select other parameters in sequence. Press the Parameter Select (▲ ▲) key to scroll upward through the parameter list.
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: 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. Early reflections are the first group of reflections you hear before the subsequent, dense reverberation begins.
LIVENESS ● REV. TIME (Reverberation Time) English ● How it Affects the Sound: How it Affects the Sound: This parameter changes the apparent reflectivity of the walls in the hall. The natural reverberation time of a room depends primarily on its size and the characteristics of its inner surfaces. This parameter, therefore, changes the apparent size of the acoustic environment over an extremely wide range.
● 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.
TROUBLESHOOTING No sound from the effect speakers. No sound from the front effect speakers. No sound from the center speaker. The sound suddenly goes off. The volume level cannot be increased, or sound is distorted. DSP parameters or other settings on this unit cannot be changed. The sound field cannot be recorded. Noise from nearby TV or tuner. Continuous functions such as volume are learned, but operate only for a moment before stopping.
