45 English 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.
46 FEATURE This is the sound field at stage front in “The Bottom Line”, a famous New York Jazz club. The floor can seat 300 people to the left and right in a sound field offering real and vibrant sound. A jazz club in New York. It is in a basement and has a relatively spacious floor area.
47 English FEATURE 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.
48 FEATURE 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 Dolby Surround or DTS (especially large-scale movie productions) are ideal for use with this program.
49 English FEATURE The built-in Dolby Pro Logic Surround decoder, the Dolby Digital decoder or the DTS decoder precisely reproduces sounds and sound effects of a source encoded with Dolby Surround or DTS.
50 AD V ANCED FEA TURES Refer to the information in the display panel or monitor screen during operation. The monitor power must be turned on to display information on the monitor. When using the remote controller, set the PARAMETER /SET MENU switch to the SET MENU position.
51 English 1. SPEAKER SET (Selecting the output modes suitable for y our speaker system) Refer to pages 26 to 27 for details. (Once you have selected proper modes, you do not have to make a setting change, unless your speaker system is modified.) m Function description 2.
52 ADVANCED FEATURES 4. CENTER DELA Y [Adjusting the dela y of center sounds (dialog etc.)] ● Control range: 0 ms to 5 ms (in 1 ms step) Preset value: 0 ms ● This adjustment is effective only when Dolby Digital or DTS is decoded and the signals of the selected source encoded with Dolby Digital or DTS contain center channel signals.
53 English 7. TV/DBS INPUT (Selecting the initial input mode of the source connected to the TV/DBS input terminals) For the source connected to the TV/DBS input terminals of this unit, you can designate the input mode that is automatically selected when the power of this unit is switched on.
54 What 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.
55 English m Selecting and editing pr ogram parameters This adjustment can be made only by using the remote controller and watching the monitor screen or the display panel. Note Information on the monitor screen would be easier to see than the display panel.
56 m 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: Changes the apparent size of the music venue. The larger the value, the larger the simulated room will sound.
57 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.
58 ● REV . LEVEL (Reverberation Level) This parameter adjusts the volume of the reverberation sound. The larger the value, the stronger the reverberation becomes. Control Range: 0 – 100% ● S. DELA Y (Surround Dela y) Adjusts the delay between the direct sound and the first reflection on the rear surround side sound field.
59 English 1 Select the source using the INPUT SELECTOR and start playback (or select a broadcast station) on the source unit. 2 Press the SLEEP key repeatedly until the desired SLEEP time appears on the display. * “SLEEP time” is the time that elapses before this unit is automatically turned into the standby mode.
60 The remote controller is designed to control the most commonly used functions. If the CD player, tape deck, LD player, etc. is a YAMAHA component with remote control compatibility, this remote controller will also control various functions. * For basic operations, the cover must be opened.
61 English REMOTE CONTROLLER 1 TAPE/MD keys These keys control tape decks or MD recorders. The A/B/C switch ( I ) should be set to the “A” position to control tape decks, and “C” position for MD recorders. * The DIR A, B and A/B keys apply only to double cassette tape decks.
62 REMOTE CONTROLLER This is a learning remote controller. The shaded keys in the illustration shown below can be programmed to “learn” control functions from other remote controllers. This unit can be used in place of other remote controllers by learning their functions.
63 English Notes • Area A cannot learn a new function. To store a new function, store it onto area B or C. • If a key which has a preset function learns a new function, the preset function will not work but is not deleted. When the learned function is cleared, the preset function is restored.
64 REMOTE CONTROLLER When the cover of the remote controller is closed, you can easily operate Yamaha components including learned functions by using the OPERATION CONTROL keys. REMOTE CONTROL TRANSMITTER TAPE/MD CD TUNER VCR 1 VCR 2 DVD/LD V-AUX EXT.
65 English REMOTE CONTROLLER Notes • If an OPERATION CONTROL key is substituted for a key which has no function (empty), then a command will not be carried out. Depending on your plan, store functions from other remote controllers into an empty area of those keys.

m Making a new macr o A new macro can be programmed onto any preset macro key in place of the factory preset functions. (See page 66 to know what keys are preset macro keys.) You can make as many as 13 new macro keys. A macro key can learn as many as seven functions of other keys.
70 REMOTE CONTROLLER 1 To clear a learned key function, press the LEARN button using a ball-point pen or similar object. To clear a macro you made, press the MACRO button.
71 English Refer to the chart below when this unit does not function properly. If the problem you are experiencing is not listed below or if the instruction below does not help, disconnect the power cord and contact your authorized YAMAHA dealer or service center.
72 TROUBLESHOOTING Problem The remote controller does not work. The remote controller 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.
73 English TROUBLESHOOTING Problem A loud hissing noise is heard when you play back a source encoded with DTS. A percussive noise is heard when you begin playing back a source encoded with DTS. No sound is heard when you play back a source encoded with DTS, even though the “AUTO” or “DTS” input mode is selected on this unit.
