The Digital Sound Field Processor (DSP) built in this unit takes full advantage of Yamaha’s undisputed leadership in the field of digital audio processing to bring you a whole new world of listening experiences. Follow the instructions in this manual carefully when setting up your system, and this unit will sonically transform your room into a wide range of listening environments –movie theater, concert hall, and so on. In addition, you get incredible realism from Dolby-encoded video sources using the built-in Dolby Pro Logic Surround Decoder. Rather than tell you about the wonders of digital sound field processing, however, let’s get right down to the business of setting up the system and trying out its many capabilities. Please read this operation manual carefully and store it in a safe place for later reference. Digital Sound Field Processing What is it that makes live music so good? Today’s advanced sound reproduction technology lets you get extremely close to the sound of a live performance, but chances are you’ll 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 you’ll feel all the sound of a live concert. What’s more, our technicians, armed with sophisticated measuring equipment, have even made it possible to capture the acoustics of a variety of actual concert hall, theater, etc. to allow you to accurately recreate one of several actual live performance environments, all in your own home. Dolby Pro Logic Surround 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. Dolby Pro Logic Surround provides a true center channel, so that there are four independent channels, unlike passive Dolby Surround which has in effect only three channels: left, right, and rear. This center channel allows listeners seated in even less-than-ideal positions to hear the dialog originating from action on the screen while getting a stereo effect as well. “ENHANCED” Dolby Pro Logic Surround The AV-90PY has a second mode of Dolby Pro Logic Surround processing called “Enhanced Dolby Pro Logic Surround” processing. Enhanced Dolby Pro Logic Surround processing recreates the surround effect of a movie theater, effectively duplicating their multiple surround loudspeaker system, completely surrounding the listener with the sounds of the action taking place on the screen. 4 This Dolby Pro Logic Surround Decoder employs a digital signal processing system. This system increases sound stability at each channel and minimizes crosstalk between channels, compared to conventional analog Dolby signal processing. In addition, this unit features a built-in automatic input balance control. This circuit always presents you the best surround conditions without performing manual adjustments.  SPEAKER SETTING UP FOR THIS UNIT SPEAKERS TO BE USED This unit is designed to provide the best sound-field quality with 5 speaker configuration. The speakers to be used with this unit will be mainly front speakers, rear speakers, and a center speaker. (You can delete a center speaker. Refer to the “4-Speaker Configuration” shown below.) The front speakers are used for the output of the main source sound and the effect sound. They will probably be your present stereo speaker system. The rear speakers are used for the output of the effect sound. And the center speaker is used for the output of the center sound (dialogue etc.) encoded with the Dolby Surround. The rear and center speakers do not need to be equal with the front speakers. However, all the speakers should have high enough power handling to accept the maximum output of this unit that will drive them. SPEAKER CONFIGURATION 5-Speaker Configuration This configuration is the most effective and recommended. In this configuration, the center speaker is necessary as well as the rear speakers. If the digital sound field program is in the DOLBY PRO LOGIC or ENHANCED, conversations will be output from the center speaker and the ambience will be excellent. ● Set the center mode to the “NORMAL” or “WIDE” position. (For details, refer to the page 11.) Front L Center 4-Speaker Configuration The center speaker is not used in this configuration. If the digital sound field program is in the DOLBY PRO LOGIC or ENHANCED, the center sound is output from the left and the right front speakers. However, the sound effect of other programs can be the same as that of the 5-speaker configuration. ● Be sure to set the center mode to the “PHANTOM” position. (For details, refer to the page 11.) Front R Front L Dialogue Dialogue Surround sound Surround sound Rear L Rear R Rear L Front R Rear R SPEAKER PLACEMENT The recommanded speaker configuration, the 5-speaker configuration, will require two speaker pairs: front speakers (your normal stereo speakers), and rear speakers, plus a center speaker. When you place these speakers, refer to the following. Front: In normal position. (The position of your present stereo speaker system.) Rear: Behind your listening position, facing slightly inward. Nearly six feet up from the floor. Center: Precisely between the front speakers. (To avoid interference to TV sets, use a magnetically shielded speaker. If, however, it is not effective, keep the speaker away from TV sets.)

Active Servo Processing speakers reproduce the bass frequencies through an “air woofer”, which is a small port or opening in the speaker’s cabinet. This opening is used instead of, and performs the functions of, a woofer in a conventionally designed speaker system. Thus, signals of low amplitude within the cabinet can, according to the Helmholtz resonance theory, be output from this opening as waves of great amplitude if the design is such that the size of the opening and the volume of the cabinet are in the correct proportion to satisfy a certain ratio. In order to accomplish this, moreover, the amplitudes within the cabinet must be both precise and of sufficient power because these amplitudes must overcome the “load” presented by the air that exists within the cabinet. 6 Thus it is this problem that is resolved through the employment of a design in which the amplifier functions to supply the signals. If the electrical resistance of the voice coil is reduced to zero, the movement of the speaker unit would become linear with respect to signal voltage, and, to accomplish this, a special negative-impedance output-drive amplifier for subtracting output impedance of the amplifier is used. By employing negative-impedance drive circuits, the amplifier is able to generate precise, low-amplitude low-frequency waves with superior damping characteristics, and these waves are then radiated from the cabinet opening as high-amplitude signals. The system can, therefore, by employing the negative-impedance output drive amplifier and a speaker cabinet with the Helmholtz resonator, reproduce an extremely wide range of frequencies (28 Hz – 20 kHz) with amazing sound quality and less distortion. The features described above, then, are combined to be the fundamental structure of the Active Servo Technology.  CONNECTIONS Before attempting to make any connections to or from this unit, be sure to first switch OFF the power to this unit and to any other components to which connections are being made. CONNECTIONS WITH OTHER COMPONENTS When making connections between this unit and other components, be sure all connections are made correctly, that is to say L (left) to L, R (right) to R, “+” to “+” and “–” to “–”.

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. Do not let the bare speaker wires touch each other and do not let them touch the metal parts of this unit as this could damage this unit and/or speakers. ● Use speakers with the specified impedance shown on the rear of this unit. How to Connect: Red: positive (+) Black: negative (–) 1 Press and hold the tab. 2 Insert the bare wire. [Remove approx. 5mm (1/4") insulation from the speaker wires.] 3 Release the tab and secure the wire. ABOUT THE ACCESSORY TERMINALS AC OUTLETS FRONT OUT terminals Use these to connect the power cords from your components to this unit. The power to the SWITCHED outlets is controlled by this unit’s POWER switch or the provided remote-control transmitter’s POWER key. These outlets will supply power to any component whenever this unit is turned on. The maximum power (total power consumption of components) that can be connected to the SWITCHED AC OUTLETS is 100 watts. These terminals are for front-channel line output. Leave the jumper bars connected to FRONT IN terminals when you use the built-in amplifier. However, if you drive front speakers with an external stereo power amplifier, remove the jumper bars and connect input terminals of the external amplifier (MAIN IN or AUX terminals of a power amplifier or an integrated amplifier) to these terminals. FRONT IN terminals REMOTE CONTROL (PHONO) connector S If you have a YAMAHA turntable with the mark, connect it to this connector by using the cable provided with the turntable. This connection allows you to control the turntable from the provided remote control transmitter. GND terminal (For turntable use) Connecting the ground wire of the turntable to this terminal will minimize hum, but in some cases better results may be obtained with the ground wire disconnected. 8 These terminals are for line input to the built-in front-channel amplifier. Leave the jumper bars connected to FRONT OUT terminals when you use the built-in amplifier. However, if you drive front speakers with an external stereo power amplifier, remove the jumper bars. CENTER OUT terminal This terminal is for center-channel line output. There is no connection to this terminal when you use the built-in amplifier. However, if you drive a center speaker with an external power amplifier, connect input terminal of the external amplifier to this terminal. If you use the built-in amplifier and the external power amplifier at the same time, the sound will be output through both speakers.  SETTING OF THE YST SELECTOR This unit can drive conventional speakers and YAMAHA Active Servo Processing speakers. Switch the YST SELECTOR (located on the rear panel of this unit ) to the appropriate position referring to the following. CONVENTIONAL position: To drive conventional speakers . YST-1 position, YST-2 position: To drive YAMAHA Active Servo Processing speakers. For detailed information on which type of speakers is appropriate to each position, refer to the rear panel of the speakers to be used. Switch Notes • Incorrect connection or miss-setting of the switch could damage this unit and the connected speakers. • Be absolutely sure that this unit’s power is OFF before setting the switch and making the amplifier-to-speakers connections. 9  ADJUSTMENT BEFORE OPERATION 1 2 3 Speaker balance adjustment Using the built-in test tone generator, this procedure lets you adjust the sound output level balance between the front, center, and rear speakers. With this adjustment, the sound output level heard at the listening position will be the same from each speaker. This is important for the best performance of digital sound field processor. 1 From the step 4, the adjustment should be done with the remote control transmitter at your listening position. (The adjustment can be done also with the controllers on the front panel of this unit. However, the result may not be as satisfactory as from your listening position.) VOLUME 0 — dB Set to the “ ∞” position. 2 — 5 BASS TREBLE 0 0 — 5+ 5 5+ 4 USER RS LEARN Set to the “0” position. 3 Set to the “RS” position.

Description of Each Sound Field Program PROGRAM PRO LOGIC ENHANCED CONCERT VIDEO MONO MOVIE FEATURE This program is effective on the play of the sources encoded with the Dolby Surround. The employment of the digital signal processing system improves crosstalk and transfers the sound source more smoothly and precisely,comparing with the conventional type. A stable movie sound field is recreated. This program is effective on the play of the sources encoded with the Dolby Surround. Enhancing the “Normal” Dolby Pro Logic, the DSP technology simulates the multi-surround speaker systems of the 35 mm film theater, so widening the surrounded-sound field with greater presence. This program is effective on music videos and excellent in depth and clarity for vocals. For opera, the orchestra and stage are ideally recreated, so letting you feel as if you were in an actual concert hall. This program is designed specifically to enhance mono source programs. Compared to a strictly mono setting, the sound image created in this mode is wider and slightly forward of the speaker pair, lending an immediacy to the overall sound. It is particularly effective when used with old mono movies, news broadcasts and dialogue. ROCK CONCERT This program will suit to rock music. A big, powerful sound is reproduced lively and dynamically. CONCERT HALL In this program, the center seems even more deeply behind the front speaker pair, creating an expansive, large hall ambience. OFF Switch : When any program is not used with the selected source, press this switch. The sound is output only from the front speakers. 16  Notes on Operation of Sound Field Programs ● In the CONCERT VIDEO, MONO MOVIE, ROCK CONCERT and CONCERT HALL, no sound is heard from the center speaker. ● When the monaural sound source is played in the DOLBY PRO LOGIC or ENHANCED, no sound is heard from the front speakers and the rear speakers. Sound is heard only from the center speaker. However, if the center mode is in the PHANTOM, the front speakers output the sound of the center speaker. ● If you connect an external amplifier to this unit, see if it has a built-in surround sound or ambience circuitry. If it does, then be sure that the surround or ambience circuitry on that amplifier is off while you are using the digital sound field processor’s Dolby Pro Logic Surround decoding function. ● When this unit is in the Dolby Pro Logic Surround mode, if the main-source sound is considerably altered by overadjustment of the BASS or TREBLE controls, the relationship with the center and rear channels may produce an unnatural effect. Description of Dolby Pro Logic Surround DOLBY PRO LOGIC SURROUND: This unit employs the Dolby Pro Logic Surround system. This system is similar to professional Dolby Stereo decoders used in movie theaters. The Dolby Pro Logic Surround system, by employing a fourchannel system, divides the input signals into four levels: the left and right main channels, the center channel (to characterize dialogue), and the rear surround-sound channels (to characterize sound effects, background noise and other ambient noise). Dolby Surround is encoded on the sound track of commercially available video cassettes and video discs as well. When you play a source encoded with Dolby Surround on your home video system, the Dolby Pro Logic Surround mode on this unit decodes the signal and feeds the surround-sound effects. The Dolby Pro Logic Surround mode may not be always effective on video sources not encoded with Dolby Surround. Manufactured under license from Dolby Laboratories Licensing Corporation.

(For details, refer to the corresponding descriptions on this page and the next page.) Note If you prefer to cancel the selected program, press the OFF switch. The sound will be the normal 2-channel stereo without surround sound effect. PRO LOGIC The corresponding indicator will illuminate. Adjustment of DELAY TIME You can adjust the time difference between the beginning of the source sound and the beginning of the effect sound with the DELAY TIME control. The DELAY TIME control is effective with all programs. By applying more or less delay, sound effects, background noise, and ambient noise coming at you from the rear speakers can be enhanced or subdued for extra effect. PRO LOGIC: from 15 to 30 milliseconds (Preset value: 20 milliseconds) 2 ENHANCED: from 15 to 30 milliseconds (Preset value: 20 milliseconds) 3 CONCERT VIDEO: from 1 to 100 milliseconds (Preset value: 25 milliseconds) 4 MONO MOVIE: from 1 to 100 milliseconds (Preset value: 25 milliseconds) 5 ROCK CONCERT: from 1 to 100 milliseconds (Preset value: 15 milliseconds) 6 CONCERT HALL: from 1 to 100 milliseconds (Preset value: 30 milliseconds) Adjustable. 1 18 ● By continuously pressing “+” or “–” of the DELAY TIME control, the value changes continuously. However, the value stops changing momentarily at the preset point. Note Adding too much delay will cause an unnatural effect with some sources. Experiment with the DELAY TIME control to create an effect that you find most suitable.  Adjustment of the FRONT EFFECT LEVEL If desired, you can adjust the effect sound output level of the front speakers with this control. The output level is preset to be 80.

If the CD player, turntable, LD player and tape deck connected to this unit are YAMAHA components designed for remote control compatibility (components with an S mark), then this remote control transmitter will also control various functions of each component. Please consult YAMAHA dealer for information on which components are compatible with the remote control transmitter. Moreover, this remote control transmitter can learn various functions from other remote control transmitters without losing the preset key functions. If you use this “learning” function, you will no more need so many remote control transmitters to control various components to be used. For details, refer to the next page. Preset Key Functions When you operate this unit and/or YAMAHA components with this remote control transmitter, set the RS-USER-LEARN switch to the RS position. For Control of This Unit RS-USER-LEARN switch Turns the power on/off. Selects input source. Selects a program from the digital sound field processor. Switch off digital sound field programs. * Refer to “Speaker balance adjustment” in “ADJUSTMENTS BEFORE OPERATION”. Selects center speaker mode. Adjusts sound output level at each speaker. When pressed, mutes the volume level. To resume original volume level, press this again. While muting, the indicator on the VOLUME control flashes on and off continuously. Turns the volume level up/down. Adjusts delay time. For Other Component Control Identify the remote control transmitter keys with your component’s keys. If these keys are identical, their function will be the same. On each key function, refer to the corresponding instruction on your component’s manual. * Refer to “Blank keys” on the next page. RS-USER-LEARN switch Controls tape deck. * DIR A, B and DECK A/B are applicable only to double cassette tape deck. Starts/stops record play on turntable.

Controls LD player. * Refer to “A/B switch” on the next page. 20  REMOTE CONTROL “LEARNING” FUNCTION The keys on this remote control transmitter can be programmed to “learn” key-functions from other remote control transmitters. By using this feature, this unit can then be used in place of one or more other remote control transmitters, thus making operation of your various audio and video components more convenient. Moreover, each key can learn two functions by switching the learning page. Use the included user program sheets to indicate a new function learned for each key. Note There may occasionally be instances, due to the signal-coding and modulation employed by the other remote control transmitter, that this unit will not be able to “learn” its signals. To Learn a New Function Notes ● When you operate the desired component with this remote control transmitter, TRANSMIT/LEARN indicator will flash steadily. ● The originally preset function of a key is still available in the USER position if a new function has not been learned to the key. ● Successful learning to a key results in the erasure of previously learned functions and their replacement by the newly learned ones. ● If there is no more room in the memory area for a function to be learned, the TRANSMIT/LEARN indicator will flash two times. In this case, even if some keys are not occupied with functions from other remote control transmitters, no further learning is possible. 1 Set to a desired learning page. 2 USER RS LEARN Set to the “LEARN” position. 3 Press a key on this unit where a new function will be learned. About 5–10 cm (2–4 in.) This unit Other remote-control transmitter 4 Memory back-up All of the learned functions will be retained while you replace the batteries. However, if no batteries are installed for a few hours, the learned functions will be erased and will have to be learned again. Blank keys (Refer to the previous page.) These keys have no preset functions and are used only for learning other remote control transmitter’s functions. Illuminates.

NOTES ABOUT THE REMOTE CONTROL TRANSMITTER Battery installation Remote control transmitter operation range Remote-control sensor Battery replacement If you find that the remote control transmitter must be used closer to the main unit, the batteries are weak. Replace both batteries with new ones. Notes ● Use only “AA”, LR6, AM-3 batteries for replacement. ● Be sure the polarities are correct. (See the illustration inside the battery compartment.) ● Remove the batteries if the remote control transmitter will not be used for an extended period of time. ● If batteries leak, dispose of them immediately. Avoid touching the leaked material or letting it come in contact with clothing, etc. Clean the battery compartment thoroughly before installing new batteries. 22 Within approximately 7 m (23 feet) 30° 30° Notes ● There should be no large obstacles between the remote control transmitter and the main unit. ● If the remote control sensor is directly illuminated by strong lighting (especially an inverter type of fluorescent lamp etc.), it might cause the remote control transmitter not to work correctly. In this case, reposition the main unit to avoid direct lighting.  TROUBLESHOOTING If the unit fails to operate normally, check the following points to determine whether the fault can be corrected by the simple measures suggested.
