47 English Notes on input mode selection f or LD sour ces • T o play bac k a Dolb y Surround A C-3 encoded source decoding its A C-3 RF signal, set the input mode to “A UT O” or “A C-3 RF”. • When you want to enjo y a Dolb y Surround AC-3 encoded source with a Dolby Pro Logic Surround prog ram, select the DIGIT AL or ANALOG mode.
48 RECORDING A SOURCE T O A UDIO/VIDEO T APE (OR DUBBING FROM A T APE T O ANO THER) 1. Set the REC OUT selector to the SOURCE position. 2. Select the source y ou want to record. 3. Pla y the source and increase the setting of the master V OLUME control to confir m it.
49 English NO TE: Adjusting the master V OLUME, BASS , TREBLE controls , etc., or selecting a sound field progr am has no eff ect on the material being recorded. NO TE: Composite video and S video signals pass independently through this unit’ s video circuits .
50 3. All sound field programs ha v e two “sub-programs” (see “DESCRIPTIONS OF THE SOUND FIELD PROGRAMS”). The sub-programs are selected using the PR OGRAM Selector on the front panel or the P arameter +/– k eys on the remote control unit.
51 English MUTING THE EFFECT SOUND The EFFECT s witch on the front panel and the EFFECT ON/OFF ke y on the remote control unit mak e it simple to compare the normal stereo sound with the fully processed eff ect sound. T o mute the eff ect sound and monitor only the main sound, press the EFFECT ON/OFF k e y or the EFFECT s witch.
52 The f ollo wing list giv es brief descriptions of the sound fields produced by each of the DSP prog r ams. K eep in mind that most of these are precise digital recreations of actual acoustic en vironments . The data f or them was recorded at the locations described using so phisticated sound field measurement equipment.
53 English 3. CONCER T HALL 3 Hall E in Europe: A classic large shoe-bo x type concer t hall with appro ximately 2200 seats . It has a circular stage and seats located behind the stage. Liv e Concer t: A large round concer t hall with a rich surround eff ect.
54 7. CONCER T VIDEO 1 Classical/Opera: This program pro vides e xcellent depth of v ocals and o v er all clarity , restraining e xcessiv e re v erber ation. F or oper a, the orchestra pit and the stage are ideally combined, letting y ou f eel a full presence sound.
55 English 9. TV THEA TER Mono Movie: This program is f or reproducing monaur al video sources (old movies etc.). Monaur al sounds are reproduced with much presence by the front presence side of the sound field and optimum re v erberation eff ect.
56 70 mm Adv enture (When the Dolby Pro Logic Surround is decoded): A C-3 Adv enture (When the Dolby Surround A C-3 is decoded): This program is ideal f or precisely reproducing the sound design of the new est 70 mm/A C-3 multi-tr ac k films .
57 English PROLOGIC/Normal (When the Dolby Pro Logic Surround is decoded): A C-3/Normal (When the Dolby Surround A C-3 is decoded): The built-in Dolb y Pro Logic Surround decoder or Dolby Surround A C-3 decoder precisely reproduces sounds and sound eff ects of a source encoded with Dolb y Surround.
58 SELECTING AND EDITING PR OGRAM P ARAMETERS WHA T IS A SOUND FIELD? In order to e xplain the impressiv e 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 w alls of the room.
59 English In addition to the “TYPE” parameter which selects the sub- programs within each sound field prog ram (e.g. “Hall A in Europe” and “Hall B in Europe” f or program 1, “CONCER T .
60 DESCRIPTIONS OF THE DIGIT AL SOUND FIELD P ARAMETERS Not all of the f ollo wing par ameters are f ound in e v ery program. ● ROOM SIZE How it Aff ects the Sound: Changes the apparent size of the m usic v en ue . The larger the v alue , the larger the simulated room will sound.
61 English ● LIVENESS How it Aff ects the Sound: This parameter changes the apparent reflectivity of the w alls in the hall. The early reflections from a sound source will lose intensity (deca y) m uch f aster in a room with acoustically absorbent w all surf aces than in one which has mostly reflectiv e surf aces .
62 ● REV . DELA Y (Reverberation Dela y) This parameter sets the time diff erence between the beginning of the direct sound and the beginning of the re v erberation sound.
63 English ● P . INIT . DL Y (Presence Initial Delay) Adjusts the dela y betw een the direct sound and the first reflection on the presence side of the sound field. The larger the v alue , the later the first reflection begins. Control Range: 1 – 49 milliseconds ● P .
64 The remote control unit, in addition to controlling the most commonly used functions of the main unit and other connected Y amaha audio and video equipment, has a sophisticated “lear ning” function that allo ws it to control other equipment in your system or other household appliances equipped with infrared remote control receiv ers.
65 English NO TE : The originally preset function of a ke y is still av ailable in the USER position if the ke y does not lear n a ne w function. NO TE : If there is no more room in the memor y area f or a function to be lear ned, the TRANSMIT/LEARN indicator will flash on and off eight times.
66 PROBLEM Power does not come on. Hum. No sound. No sound from the effect speakers. No sound from the front effect speakers. No sound from the center speaker. Poor bass reproduction. The sound suddenly goes off. The volume level cannot be increased, or sound is distorted.
67 English PROBLEM The sound is degraded when listening with the headphones connected to the compact disc player or cassette deck that are connected with this unit. The remote control unit does not function properly. The remote control unit cannot learn a new function from another remote control unit.
