 of Nintendo.

 About a new 5.1ch surround system


(1) Cause Which Makes This

 The question came.
 (1) In the direction which made D-58 of .20cm on our side, a home theater is enjoyed
   fully.
 The complaint has come from D-58 and rear Family. Isn't there any better thing?
                                                  Mr. N
 
 (2) The thin shape liquid crystal big screen TV was purchased by .9 mat. The speaker
   suitable for this room
   It is inquiring. Aren't any good things found?
                                                  Mr. A

  Answer

  
The question of (1)
  I am with large volume until now, although it was doing by D-58ES, and NessieJr
   / rear canon II.
  Although the Ohasama power is good, the problem of that it cannot sound at midnight
  , an audition taking it easy
  I am and have thought that a home theater is not turned to. With D-58ES and rear
  Nessie Jr
  I think that it is at a thing with suitable mainly hearing it as a DVD audio or a stereo
  chiefly.
  It came. Since there is no image, a nerve makes it strain oneself in sound, if it is
  this. Since it can concentrate on sound so much and gets tired, it does not become
  precocious.
  And another problem is the balance of a front and rear. If a front is too strong
  rear stops being able to hear. This balance is the system of a different unit or a
  different speaker.
  It will happen, if a speaker is used. For many things, I found the following thing, as
   a result of trying.

 
    
Surround speakers system is this.
  1. Use the same unit for all by the full range of the diameter of a small sum.
   Just the full range of a dynamic range of the diameter of a small sum is large.
   If it is the same unit, volume will be the same and sound will also become the
   same.
  2. Use the speaker of the same system.
   A bus reflex or BH is sufficient. a minimum front and rear -- the same
   A speaker is used.
  3. Although it is natural, 5.1ch(es) are not made with stereo amplifier. An AV
    amplifier is used.

                   
  
A cause is this.
 There is 99dB of output sound pressure levels of D-58ES. Supposing rear uses
  what has 99dB
 Although it is satisfactory, if 2 sets of D-58ES(s) are placed, probably it will become
 torture of sound.
 Since D-58ES wins rear completely by 10cm by D-58ES in the front, it is rear
 It will not be audible. It can be barely heard somehow by 16cm.
 that to which it and a home theater enjoy an image -- it is -- 20cm -- strong --
 becoming -- passing -- coming out -- an image

 
The way of sound will be emphasized.
 It is the system which is asked to it in comfort since a family bears a powerful
  sound and it does not in it if together with a family.
 The method of is good.
 For me, D-58 is hearing 5.1ch multi in the stereo or DVD audio only for oneself.
 We recommend you.
 Please consider a home theater by the new 5.1ch surround system together with
 a family.



  
The question of (2)
 I think that the direction which enjoys a home theater at 9-mat grade will increase
  from now on. Happy handmade speaker
 According to the room, as for - car, a design is also possible. By my design, it is new
  5.1ch surround.
 A stem uses an AV amplifier and all units use the same thing.
 When this is the important and same unit, since it is the same, an output sound
 pressure level is a front/center.
 Since rear volume is the same, each speaker has come to be independent.
 I am a bus reflex system, and designed / manufactured MG850 this time at 6 usage
  basic target.
 If it tries listening this, when music will also be listened to also by Wii in the position
 of the middle of sound, it is 360 degrees in sound.
 It became what is contained in the world of spreading 3D. At Wii, they are especially
 an image

 Since sound moves to the right from the left or sound moves to back from before,
 the game is done.
 He can turn completely now into a hero.
 Since sound is not noisy, either, I think that families can also be enjoyed.
 Since MG850 has ended sale, my design is 12cm FX120 or
 It is the design which can use F120A of use.


 (2) New 5.1ch Surround System

       
     A fundamental system D-58ES / super swan of a photograph are not used.


                   Front BB-69mg.iIIx2
                   Center BS-49mg.ix2

 A center is usually a parallel connector in two from the terminal of a center but one.
 It has connected. In the case of the thin shape liquid crystal big screen TV, it places
  beside TV.
                   Rear BB-69mg.iIIx2

 FX120/F120A is used as substitution. Dynamic FX120
 F-120A which has a high-class feeling using a magnet is used.

 Width of the room
 Although there are 20 rooms of mine, this system is put on ten halves.
 It is a system with a furniture sufficient at ten - 8 mats.
     
 Used unit A Sato style its original work network is used for MG 850x6.
 It is good also for the /sound which protects beautifully the /unit to which a
 unit becomes new.
 Those [ a Sato style its original work network's who use recently are increasing.
 Please give me purchase with E-plywood cut service.

 Although it does not use since sufficient low-pitched sound can be made, even
 if there is no sub woofer
 Since the sub woofer with amplifier is recommended in the AV amplifier
 If it thinks that low-pitched sound is insufficient, I will think that an addition is good.
 As me, a sub woofer recommends you handmade.

 It is the system which can be done by all units being using the same thing although
 emphasized.
 Responsibility cannot be taken when other things are used.

         
         
 (3) Practice of New 5.1ch Surround System by Wii
 They are two centers in front. They are two fronts to right and left. Although two
 are used for rear
 It is surround of Wii to have been surprised although the feeling of a sound place
  which spreads at 360 degrees was also good by music.
 It came out and carried out. Being in furniture middle (it is back a little), a feeling
 surround is impending.

 Sound turns into sound of surround united with the image in a scene scene.
 Although the whole is from a front/center fundamentally, sound like a sight is from
 rear
 It is audible. It is the machine sound of the little stream/mine of sound/river etc.
 without an insect.

 A center is important. A sound omission only by right and left because there is a
 center
 Although it happened at the time of a stereo, since there is this [ no ], sound
  sounds thick from front [ whole ].
 Feeling is also just carried by the highest and it is in the end. It will get hot at
 a game.
 since I was one of the fans of Nintendo from the Family Computer time true
 Nintendo thinks that it took out the uncanny thing. Having experienced until now
twists this Zelda

 Since sound is also DVD in surround, sound is also wonderful and it is on a 110
 inches wide screen about this.
 I regard that it can feel on a screen as a really uncanny thing.
 He considers that I also want you to myself but surely feel, and looks at this page
. [ not only ]
 I think that what is necessary is just to inquire.

 Moreover, a physical feeling candidate needs to inspect nearby one on us by all
  means.
     

     
        
 
The demonstration screen of the tradition of Zelda is photographed with a camera.

 A link and favorite horse move to the left from the right. The footprint of the horse
  at this time should disappear on the left.
 Sound moves.
 Although it is arrangement of a screen, and the two the front right / centers / front
  left, it is a screen in this way.
 If (110 inches) are placed well, it turns out that sound moves truly.
 In this case, +- of a unit is making it +- of amplifier to prevent mistakes.
 Since it is having [ me ] red mark for + side of a code, a black mark is - side.
 + The red vinyl tape is surely stuck to the side.
 Since the phase is not right, it may not move by the mistaken wiring.


 
The connection method of my Wii
 1. D4 terminal of Wii is directly connected to a liquid crystal projector.
 In this case, it corresponds to D2 and is set to 525P (progressive).
 Although the component terminal was used before this, the direction of D4
 terminal a color
 It becomes vivid. Especially green/blue became beautiful.

 2. sound -- AV: of D4 terminal -- a cable -- an extended cable -- lengthening
    -- an AV amplifier
 It has connected with an input terminal. There is no optical cable in Wii.
 The AV amplifier after connection is set as Dolby prologic II.
          


 
The description about Dolby prologic II was also understood by cooperation of
  Nintendo.
 Please have a look for details here.

 1. Connection is Dolby Prologic II Correspondence about Voice Terminal of AV
   Cable Enclosed.
   It only connects with an AV amplifier.
 2. It is required for game software to deal with Dolby prologic II.
   In addition, the tradition of Zelda corresponds.
   The Family Computer software which can be downloaded in a network is a
   monophonic recording.

 3. By CD or DVD Video, although it is in how, Changing Stereo to 5.1Ch(es) as
   Another 5.1Ch
   Since it is Dolby prologic II, he can be enjoyed by surround satisfactory.

 4. Connection of Wii needs to make it surround with a main part setting menu.

   Since it links from here, please look at explanation of Nintendo.

  Although explained by the game cube, it is the same also at Wii. For Wii, it is still.
  It is a thing that the page is not made.
  surround is also at Wii, although there is much direction currently considered to
  be only playstation 3
  Since you can do, please enjoy 5.1ch(es).

 Please give me a question, such as not understanding, from the homepage of
 Nintendo.
       
  Please look at the homepage of Nintendo from here.



 
 (3) About BS-49mg.i, it is under construction.
