FEATURES

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. This unit has a total of 12 digital sound field processor (DSP) modes. You can create an excellent audio sound field by selecting a suitable sound field (this will, of course, depend on what you will be listening to), and adding desired adjustments. In addition, this unit incorporates a Dolby Pro Logic Surround decoder and Dolby Surround AC-3 decoder for multi-channel sound reproduction of Dolby Surround encoded video sources. The operation of the Dolby Pro Logic Surround or Dolby Surround AC-3 decoder can be controlled by selecting a corresponding DSP program including combined operations of the Yamaha DSP and the Dolby Pro Logic Surround or Dolby Surround AC-3 decoder.
Digital Sound Field Processing
What is it that makes live music so good? Todays advanced sound reproduction technology lets you get extremely close to the sound of a live performance, but chances are youll still notice something missing, the acoustic environment of the live concert hall. Extensive research into the exact nature of the sonic reflections that create the ambience of a large hall has made it possible for Yamaha engineers to bring you this same sound in your own listening room, so youll feel all the sound of a live concert. Whats more, our technicians, armed with sophisticated measuring equipment, have even made it possible to capture the acoustics of a variety of actual concert halls, jazz clubs, theaters, etc. from around the world, to allow you to accurately recreate any one of these live performance environments, all in your own home.

Dolby Pro Logic Surround

This unit employs a Dolby Pro Logic Surround decoder similar to professional Dolby Stereo decoders used in many movie theaters. By using the Dolby Pro Logic Surround decoder, you can experience the dramatic realism and impact of Dolby Surround movie theater sound in your own home. Dolby Pro Logic employs a four channel five speaker system. The Pro Logic Surround system divides the input signal into four levels: the left and right main channels, the center channel (used for dialog), and the rear surround sound channels (used for sound effects, background noise, and other ambient noises). The center channel allows listeners seated in even lessthan-ideal positions to hear the dialog originating from the action on the screen while experiencing good stereo imaging. Dolby Surround is encoded on the sound track of pre-recorded video tapes, laser discs, and some TV/cable broadcasts. When you play a source encoded with Dolby Surround on this unit, the Dolby Pro Logic Surround decoder decodes the signal and distributes the surroundsound effects. This Dolby Pro Logic Surround Decoder employs a digital signal processing system. This system improves the stability of sound at each channel and crosstalk between channels, so that positioning of sounds around the room is more accurate compared with conventional analog signal processing systems. In addition, this unit features a built-in automatic input balance control. This always assures you the best performance without manual 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 SUR. appears on 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, right rear effect speaker and left rear effect speaker in turn (see diagram). Adjust the master VOLUME to a normal listening level. * The state of test-tone output is shown by the display panel and the monitor screen. (On the monitor screen, it is shown by an image of audio listening room.) This is convenient for adjusting each speaker level.
Left main LEFT Left rear LEFT SURROUND Center CENTER Right rear RIGHT SURROUND Right main RIGHT
If there is insufficient volume from the effect speakers, you may decrease the main speaker volume level by setting the MAIN LEVEL switch on the rear panel to 10 dB, and adjust the center and rear level again. Volume controls on external power amplifiers may also be adjusted if necessary to achieve proper balance. Pressing the Parameter + or key (only when the PARAMETER/SET MENU switch is set to the PARAMETER position) transfers the test-tone from the speaker that is currently outputting the test-tone to the right or left rear effect speaker. Pressing + transfers the test-tone to the right rear effect speaker, and to the left rear effect speaker. Pressing and holding the Parameter Select w or v key (only when the PARAMETER/SET MENU switch is set to the PARAMETER position) fixes the test-tone on the speaker that is currently outputting the test-tone.
2. Adjust the center and rear level by using the CENTER and REAR LEVEL +/ keys on the remote control so that the sound coming from the corresponding speaker seems to be at the same level as that from the main speakers when you are at a normal listening position. The REAR LEVEL +/ keys adjust the right rear level if pressed while the test-tone is output from the right rear effect speaker, and adjust the left rear level if pressed while the test-tone is output from the left rear effect speaker. If the REAR LEVEL + or key is pressed while the test-tone is output from other than the right or left rear effect speaker, the key adjusts either the right or left rear level that has been adjusted last time.
NOTE: If not using a center speaker, be sure to set the CENTER SP mode to the PHNTM (phantom) position. You will then hear the center channel test tone from the left and right main speakers.

11. INPUT TRIM (Input level adjustment)
This function is available to all input sources. Select an input source with the INPUT SELECTOR on the front panel or the input selector keys on the remote control unit.

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. * 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. This is due to the fact that most of these sound field recreations are actual acoustic environments. 1. CONCERT HALL 1 Hall A in Europe: This is a large fan-shaped concert hall in Munich which has approximately 2500 seats. Almost the whole interior is made of wood. There is relatively little reflection from the right and left walls, and sounds spread finely and beautifully. 2. CONCERT HALL 2 Hall C in Europe: A classic shoe-box type concert hall with approximately 1700 seats. Pillars and ornate carvings create extremely complex reflections. Those reflections and the reflections from all directions of the hall produce a very full, rich sound.

Hall B in Europe:

This is a large shoe-box type concert hall with approximately 2500 seats. Almost the whole interior except the ceiling is made of wood, including mahogany reflective panels. Special reflective paneling above the stage produces strong frontal reflections which tend to reinforce the direct sound from the stage. This hall has a very solid, powerful sound.

Hall D in U.S.A.:

This is a large 2600-seat concert hall in the United States which features a fairly traditional European design. The interior is relatively simple, suggesting an American taste. Sound of the middle and high frequencies are richly and beautifully reproduced.
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.
5. ROCK CONCERT The Roxy Theatre: The ideal program for lively, dynamic rock music. The data for this program was recorded at LAs hottest rock club.
Warehouse Loft: 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. This is because you feel as if you are standing on a real stage. 6. JAZZ CLUB The acoustic environment of an ordinary church with moderate reverberations. This is ideal for reproducing church music played by a pipe organ etc. Village Gate:
