在投影机领域，日本三菱绝对算得上是一个实力派角色，旗下的DLP投影机HC系列更是深得业内发烧友的喜爱。10月下旬开始，三菱的最新两款720P投影机就要在国内上市发售了。
The HC1100's formatter board is equipped with a combined full 10-bit processing I/P converter and scaler, and a 12-bit floating point digital gamma controller. The result is approximately four times the number of gradations of a conventional 8-bit model, so even skin tones are faithfully reproduced.
A high-speed memory (RLDRAM) with improved data transmission efficiency, and a high-speed LVDS drive provide subtle gradations of expression rivaling high-end models.
Data transmission flow
8-bit (256 steps) 10-bit (1024 steps): Approx. 4 times the number of gradations
The HC1100 is equipped with the latest 720p DMD panel (DC2) featuring an expanded mirror operation angle of 12 degrees. This advanced panel's exceptional light usage efficiency provides a contrast of 3000:1.
2000:1 contrast (Mitsubishi Electric's previous model) 3000:1 contrast All-glass lens
For more realistic color reproduction of the visual source, the HC1100 is equipped with a color wheel capable of reproducing the D65 light standard (6500 K).
A new color processing algorithm and system-level color signal image enhancement processing provide bright, vibrant reproduction of the neutral colors commonly found in videos and natural scenery. The three-stage adjustment function further enhances this breakthrough.
A full 10-bit I/P conversion circuit markedly reduces noise, for smooth, beautiful images with fewer ”jaggies” (stair-like lines).
Previous 8-bit New 10-bit
The HC1100 features 2-3 pull-down to significantly reduce ”jaggies” in interlace (480i or 576i) movie sources. In addition, the combination of several functions also enables each mode -- either high brightness or high picture quality -- to be easily selected according to the image.
In addition to the 3 modes of sports, video, and cinema, for times when the normal brightness function cannot address user preferences such as a desire to increase black level reproduction, brighten neutral colors, or suppress highlights when watching a movie, the gamma correction function makes it possible to independently fine-adjust only the black level, neutral color, or white and gradations.
Operating noise has been reduced to just 26 dB by employing a low-noise fan and redesigning the shape of the color wheel holder and lamp fins. Moreover, the optimal temperature control design used for the 200W light source lamp extends the lamp's useful life to a maximum of 3000 hours.
Long-life lamp
*Maximum of 3000 hours at low mode and 2000 hours at standard mode.
*Lamp life is defined as the average time until brightness is reduced by half; it is not a guaranteed life for all lamps.
*Lamp life will vary considerably depending on the usage environment and conditions, and whether regular maintenance such as cleaning is performed.
In order to make it easier to align the projection angle with the center of the screen, the lens is positioned in the center of the unit. Hot air is expelled through a front exhaust for further installation flexibility.
Front of unit
The HC1100 is equipped with HDMI input terminals, the next-generation interface standard. Connecting the projector to a DVD player or other device with HDMI output makes it possible to take advantage of the characteristics of DLP full digital processing. Digital processing of all signals with no analog conversion ensures that the image is projected with no deterioration. Color gain control at the time of input is also possible. (when there is a color difference)
Terminals on back of unit
*1 HDCP (High-bandwidth Digital Content Protection) is a copyright protection function for digital interfaces.
*2 HDMI (High-Definition Multimedia Interface) is a next-generation digital interface standard that features additional functions for home electronics, such as the copyright protection function HDCP (High-bandwidth Digital Content Protection), while maintaining compatibility with DVI (Digital Visual Interface) display interface technology.
• HDMI, the HDMI logo, and High-Definition Multimedia Interface are trademarks or registered trademarks of HDMI Licensing LLC.
The overscan rate for images on DVDs and other media can be adjusted between 90% and 100% in one-percent increments (when an HDMI component is connected).
The HC1100 is equipped with a screen trigger that synchronizes raising and lowering of an electrically-operated screen with the projector power switch, so projection can begin at the touch of a button.
Digital trapezoidal distortion correction corrects screen distortion within ±40 steps vertically and ±25 steps horizontally (one step is equivalent to approximately one degree).
The image quality can be directly adjusted via the remote control. The remote control is lighted for easy operation even in a dark room.

发烧级的设计，纯净的信号还原——雅堡HDMI-Y（发烧级，2007升级版，获家庭影院技术年鉴2007年度推荐产品奖）《家庭影院技术、新音响、视听前线、高保真、现代音响技术等杂志2006年12期报道文章》
加钱还可得到外观精美，品质出色的HDMI线
可以同时传输音视频数字信号的HDMI标准自2002年问世以来，对整个影音行业产生了巨大的影响，几乎已经成为众多AV产品的标准配置，随着各种高清影音设备的逐步上市，HDMI将会有更大的用武之地，众多国际知名的线材厂家也顺应时代潮流，纷纷推出高品质的HDMI线材产品。雅堡推出的HDMI-Y线材便是其中的佼佼者。
一些质量较差的HDMI线材品质不稳定，因为HDMI线在传输使用中带有微电流，在使用时间较长后线内温度变化会造成电磁感应，致使画面突然消失、拖尾、对比度明显降低、背景噪点增多，如果在欣赏高清影像的时候遭遇这种情况，是一件极为烦心的事情。选购一条优质的HDMI线材也就成为值得关注的问题。
来自德国的雅堡（YARBO）是国际著名线材品牌，有着三十多年的悠久历史，一直致力于研发、生产不同行业不同标准的高品质线材，并且为不少知名音响品牌OEM、ODM各种专业级和发烧级线材，旗下产品种类繁多，从音频线到视频线一应俱全，形成一个丰富的产品网络。这一款HDMI-Y是雅堡全新推出的2007升级版发烧级HDMI线材。
外观精美，品质出色
作为一款高档发烧级HDMI线材，雅堡HDMI-Y的外包装也同样档次较高，圆形的铝盒散发着银色金属光泽，让人感到这款线材的气质典雅。HDMI-Y线材经雅堡德国总部多次研发与不断改进，本次推出的2007年升级版，品质更加稳定、信号传输效果更佳。导体采用100%镀厚银OFHC（高导无氧铜），并以多层高密度的屏蔽层包裹，达到100%屏蔽效果，具有极低干扰和低抗阻的特点。接头部分为电镀24K厚金，加上外观精美的专利金属镀金外壳，既美观大方又确保品质稳定可靠。HDMI-Y线材的两端还装配原装进口的强力滤波磁环，能够有效地过滤杂波，进一步降低干扰，使得信号更纯净。
出色的信号还原
在实际的HDMI视频输出测试中，这条雅堡的发烧级HDMI-Y线材表现出了极为出色的画质。与市面上的一般HDMI线材相比，HDMI-Y能更好地还原数字视频信号，画面的层次感更为分明，明暗对比强烈。输出色彩丰富、信息量大的视频信号时，HDMI-Y的优势更为明显，色彩鲜艳明亮，质感极为细腻，画面也极为清晰锐利。得益于HDMI-Y的多项抗干扰设计，视频信号的杂讯极低，画面纯净。
过去发烧友对于线材的注意力主要都放在信号线、音箱线等音频线材上，随着高清视频技术的发展，HDMI数字传输技术的成熟，HDMI数字传输线材也受到了更多发烧友的关注。雅堡推出的这一款HDMI-Y线材，在设计和工艺上完全达到了极高的水准，不愧为“发烧级”HDMI线材。
