4 This unit is not disconnected from the AC power source as long as it is connected to the wall outlet, even if this unit itself is turned off. This state is called the standby mode. In this state, this unit is designed to consume a very small quantity of power.
5 English PR OFILE OF THIS UNIT 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.
The DTS (Digital Theater Systems) system was developed to replace analog soundtracks of movies with six discrete channels of digital soundtracks, and now, it is installed in many theaters around the world. The DTS digital playback system changed the way we experienced movies in theaters with six discrete channels of superb digital audio.
7 English Dolby Pr o Logic + 2 Digital Sound Fields Digital sound fields are created on the presence side and the rear surround side of the Dolby Pro Logic Surround- decoded sound field respectively.
8 This unit has been designed to provide the best sound field quality with a full seven-speaker system setup, using a pair of main speakers to output main source sounds, two extra pairs of effect speakers to generate the sound field plus one center speaker for dialog.
9 English 4 Speaker System Simplest system. You can enjoy widely diffused sound by only adding two additional speaker units at the rear. 1E. FRONT MIX—Set to ON-5ch. (See page 27.) 1A. CENTER SP—Set to NONE. (See page 26.) 6 Speaker System Good for sound fields from 2-channel stereo sources.

50 The following list gives you a brief description 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 these sound fields were recorded at actual locations using sophisticated sound field measurement equipment.
51 English FEATURE The acoustic environment of an ordinary church with moderate reverberations. This is ideal for reproducing church music played by a pipe organ etc. This program recreates the acoustic environment of a big church with a high pointed dome and columns along the sides.
52 FEATURE This program produces an enthusiastic atmosphere and lets you feel that you are in the midst of the action, as if attending an actual jazz or rock concert.
53 English FEATURE This program creates the extremely wide sound field of a movie theater. It precisely reproduces the source sound in detail, giving both the video and the sound field incredible reality. Any kind of video sources encoded with the Dolby Surround or DTS (especially large-scale movie productions) are ideal for use with this program.
54 FEATURE The built-in Dolby Pro Logic Surround decoder, the Dolby Digital (AC-3) decoder or the DTS decoder precisely reproduces sounds and sound effects of a source encoded with the Dolby Surround or the DTS.
55 English ON SCREEN DISPLA Y If you connect your video cassette recorder, LD player, video monitor, etc. to this unit, you can take advantage of this unit’s capability to display program titles, parameter data and information for various setting changes and adjustments on your video monitor’s screen.
56 CREA TING Y OUR O WN SOUND FIELDS WHA T IS A SOUND FIELD? In order to explain the impressive functions of the DSP, 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.
57 English SELECTING AND EDITING PR OGRAM P ARAMETERS This adjustment can be made only by using the remote control transmitter watching the monitor screen or the display panel. Note It is recommended to watch the monitor screen for making adjustments more easily than to watch the display panel.
58 DESCRIPTIONS OF THE DIGIT AL SOUND FIELD P ARAMETERS Not all of the following parameters are found in every program. ● R OOM 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.
59 English ● 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.
60 ● REV . DELA Y (Reverberation Dela y) 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.
61 English 1 Whenever the SLEEP key is pressed, the SLEEP time will change as follows. After a while, the display returns to the indication before the SLEEP timer is set. 2 The unit will be turned into the standby mode automatically at the selected SLEEP time.
62 B ASIC OPERA TIONS (When the lid is open) The remote control transmitter provided with this unit is designed to control all the most commonly used functions of this unit.
63 English 1 Tape deck keys Control tape deck. (The A/B/C switch ( G ) should be set to the “A” position.) * DIR A, B and A/B are applicable only to double cassette tape deck. * For a single cassette deck with automatic reverse function, pressing DIR A will reverse the direction of tape running.
64 LEARNING NEW CONTR OL FUNCTIONS (When the lid is open) This is a learning remote control transmitter. The shaded keys in the illustration shown below can be programmed to “learn” control functions from other remote control transmitters.
65 English Note If a key which has a preset function learns a new function, the preset function will not be deleted, but disabled. When the learned function is cleared, the preset function is restored. (For information on clearing a learned function, refer to page 72.
66 USING OPERA TION CONTROL KEYS (When the lid is c losed) When the lid of the remote control transmitter is closed, you can easily operate Yamaha components including learned functions by using the OPERATION CONTROL keys.
Notes • If the OPERATION CONTROL keys substitute for keys which have no function (empty), no command is carried out. According to your plan, store functions from other remote control transmitters into an empty area of those keys. (Refer to page 70 for the learning method.
68 MA CRO OPERA TIONS (When the lid is closed) “Macro” is a command which defines a sequence of several operations. The keys shown in the illustrations below (as preset macro keys ) are also preset with macros, in addition to individual functions.
69 English Macro key 1st (Turning the power of this unit on) 2nd (Selecting an input source) 3rd (Playing a source) “ ” on area A of keys 1 “ ” on area A of keys 2 – “ ” on area B of key.
70 LEARNING A NEW FUNCTION 1 Place this remote control transmitter and the other remote control transmitter so that they face each other. 2 * If there is no operation for about 30 seconds after the LEARN button is pressed, the TRANSMIT/LEARN indicator flashes rapidly and the current mode is canceled.
71 English 1 * If there is no operation for about 30 seconds after the MACRO button is pressed, the TRANSMIT/LEARN indicator flashes rapidly and the mode before you pressed the MACRO button is restored. If this occurs, press the MACRO button again. 2 Press a preset macro key on which you want to make a new macro.
72 1 To clear a learned key function, press the LEARN button using the point of a mechanical pencil, etc. To clear a macro you made, press the MACRO button.
73 English If the unit fails to operate normally, check the following points to determine whether the fault can be corrected by the simple measures suggested. If it cannot be corrected, or if the fault is not listed in the SYMPTOM column, disconnect the power cord and contact your authorized YAMAHA dealer or service center for help.
74 SYMPTOM The remote control transmitter does not work. The remote control transmitter does not function properly. Learning cannot be made successfully. (The TRANSMIT/LEARN indicator does not light up or flash.) Continuous functions such as volume are learned, but operate only for a moment before stopping.
75 English SYMPTOM A loud hissing noise is heard when you play back a source encoded with the DTS. A percussive noise is heard when you begin playing back a source encoded with the DTS. No sound is heard when you play back a source encoded with the DTS, even though the “AUTO” or “DTS” input mode is selected on this unit.
