Overview | |
The capacity of theater room ,what is originally designed only for a "hometheater"
is 250-cubic meter. The interception, absorption and modulation of the
sound are elaborately considered there.It has isolated ground and 200V
power line,signal line with wiring through hidden floor pit. Screen is a voice penetration type of 200 inches. and front projector is fixed pixel type of ILA. Acoustical instruments are mainly for professional use and tuned by FFT software, "Smaart". Moreover, wood and goldsmith works of hobby, self-made PC are equipped.Devices are arranged not to come into sight excluding the screen. |
シアタールームはSRC 250?で、躯体設計段階からシアター専用として遮音・吸音・調音を考慮しています。AV用専用電源や基礎工事で埋設した接地線、室内配線は専用ピットを設けています。映像機器は200インチの音声透過型スクリーンと固定画素のフロントプロジェクター。音響機器は主に業務用で、ソース機器の一部に民生用を使用しています。音響調整はSmaartで実施。また趣味の木工や金工細工、自作PCも取り入れています。スクリーン以外は視界に入らないよう機器を配置しています。 |
Introduction | |
This is a renewal site of "monolith-theater". I have arrived at this environments that specializes to watch movies, through experience for 30 years of pure-audio and 20 years of hometheater. Recently, defective operation has happened frequently with my consumer audio devices, while overhauling over many years, I tried to replace the system with professional devices. The site was started up as a chronicle because there were various surprises and discoveries in this process as an amateur. "Get impressed image and sound more than commercial theater!."Thanks for your visit. (monolith-theater.net) |
monolith-theaterのリニューアルサイトです。 約30年のオーディオと20年のビジュアル歴を経て、現在の映画鑑賞に特化した環境に至っています。長年にわたり、オーバーホールしながら愛用した民生用オーディオ機材も動作不良が頻発し、最近業務用機材を中心としたシステムに入れ替えました。その過程で、アマチュアとして様々な驚きと発見があったので、忘備録としてサイトを立ち上げました。「映画館の映像と音響を上回る品質で、自宅で映画の感動を」。興味ある方はどうぞご覧ください。(monolith-theater.net) |

Image and sound impression |
Image quality All image qualities are excellent by the impression of tens of blu-ray up to now. The image seen with DLA-HD100 looks more exact than the film. Because of the high resolution and contrast ratio, depth of scene is often real. Sound quality Screen Array system create an elegant, delicate, listenable and real voice. The preconception of the professional equipment that secure stable operation, sound volume and the head-room changed completely. Comparison with consumer products It might be difficult to surpass this quality by combination of high-end audio devices for consumers, judging from my experiences of household machines as pure -audio. However, the tuning and optimization of professional devices with multi- amp system is extremely difficult. For example, it takes over three days by FFT analyzer "Smaart", until constant flat characteristic data of the response in frequency is obtained including room acoustic equalizing. Impression of Screen Array The dialog seems as if to see the movement of the lip and the throat. It is real to make it think there is an actor in the back of the screen. Each musical instruments are able to be listened lucid separating one by one in the orchestra. Transient characteristic quality such as brass and woodwind instruments is excellent. Response of low frequency is very tight. I think that it is a synergy effect of amplifiers with high density power and damping factor, natural digital devices without coloration, unique mid-range double unit with horn and double woofer of 3632T. The horn in high frequency band is average. It is a preamp of DENON that has colored character most in this system. On the other hand, the reproduction as DAW system via firewire and AES3 digital signals by PC is accurate. Surround sound In some movies,I can feel the orchestra instruments how like exists and sings. I can hear the orchestra pit in the theater under of screen. Musical instruments queue up from near to far and right to left.When equipped 8 surround speakers, the surround is so natural that the sound-image moves from center to outside the screen and side to back smoothly. The density of the sound that develops with overhead is high. Conclusion I have not experienced such the sense absorbed in stories without feeling the sign of devices. Only the movie exists there. |
