VP15S1

1080p HD DLP Projector

[Background]
Last year, a large number of full-HD projectors from both the LCD model and DLPR model makers were sold on the market. Blu-ray and HD DVD players, next-generation players that are capable of full-HD image output, were also introduced into the market, resulting in advances occurring across the board in terms of the adoption of full-HD technology in flat panel TV sets, video cameras and other video equipment. The HDMI specification version under which these full-HD devices connect to each other has been upgraded to HDMI ver.1.3. In 2007, the projector industry is expected to launch full-HD models similar to what they released last year, along with some minor changes incorporated to support HDMI1.3 with more low prices.

[Design concept / strategy]
Marantz achieved compliance with HDMI ver.1.3 with the VP-11S1H; however, to survive in the current marketplace, competition must now focus on providing high-level models in the price range below $10,000. Sales above this range are likely to be severely limited.
For this reason, Marantz will be appealing to customers one new models for 2007 - the VP-15S1, which is a lower-cost version of the VP-11S1H. The VP-15S1 is the leading model designed to compete with $8,000 class LCD projectors.

VP-15S1 Selling Points

1. HDMI Ver 1.3
2. Dual Iris
3. High Contrast Ratio 10,000 : 1
4. Higf Brightness 1000 Lumens
5. Big diagonal 98mm, 6 segment color “SilentWheelTM” wheel
6. New printing design matching for Front and Ceiling installation

1. HDMI ver.1.3
The HDMI connectors of VP-15S1 is supported with HDMI ver.1.3 (Deep Color) as well as VP-11S1H. It has passed by latest authorization test standard “HDMI ver.1.3b”.
Deep Color…This feature has been achieved by extending the color depth. In the past, 8-bit RGB or Y/Cb/Cr was supported, and this was generally referred to as True Color or full color. However, “Deep Color,” the new specification, supports up to 16 bits, including 10 bits and 12 bits. The VP-11S1H supports up to 12 bits. In pitching the fact that Deep Color is supported, it is necessary for the product concerned to support up to 12 bits at the least, and supporting this automatically means that higher speed is also supported.
24bit (8bit x3) = 28 x 28 x 28 = 16,777,216 Color (16Million)
30bit (10bit x3) = 210 x 210 x 210 = 1,073,741,824 Color (1Billion)
36bit (12bit x3) = 212 x 212 x 212 = 68,719,476,736 Color (68Billion)
48bit (16bit x3) = 216 x 216 x 216 = 281,474,976,710,656 Color (280Trillion)

2. Dual Iris
The iris employed previously in the VP-11S1 was incorporated in the projection lens (after DLPR Chip), but in the VP-15S1, an iris has also been included on the lamp side (before DLPR Chip). By adding the lamp-side iris, the design of the optical system for the part shown in orange below has been renewed and optimized (Atsmahica rod and four lenses).

Opening and closing these irises allows the brightness and contrast to be set to the desired levels.

The position No.2 is an almost identical mode to the closed iris condition of the previous model. Theoretically, the projection iris ON/OFF combined with the lamp iris ON/OFF provides a total of four combinations. Opposite pattern to No.2 is possible, but as there is negligible difference in the effect, they have not been included.
3．High Contrast ?10000:1
In addition to the previously mentioned dual iris, the VP-15S1 surpasses the VP-11S1 in contrast, achieving a value of 10000:1.

5．Big diameter 98mm, 6 segment color wheel
The VP-15S1 use an Oerlikon’s(*) SilentWheelTM color wheel (CW) that has low running noise and a long service life. *OC Oerlikon Management AG: HQ in Switzerland

6segment SilentWheelTM Color Wheel for VP-15S1

The VP-15S1, on the other hand, uses a 6 segment CW (RGBRGB) to achieve high brightness. The color filter characteristics and the angles for each color (distribution) have however been re-examined and newly developed.
Both of these color wheels are 98 mm in diameter, with larger apertures than those in other companies’ models, and they contribute to high brightness.

6. New printing design matching for Front and Ceiling installation
The printed position of the Marantz logo has been changed so that even when the VP-15S1 are suspended from the ceiling the logo will not appear upside down. The Marantz logo and model name, which had previously appeared on the side of the lens, have now been positioned on the upper surface of the unit on the same line as the other license logos.

[Other features]
The new feature of VP-15S1 are above. Here are other features again for your review.

Custom optics by Konica Minolta (+165% Lens shift, 1.45x zoom)
The familiar Konica Minolta custom lens is seeing continued use in the new models. As the DLPR projector with the greatest shift range, the display can be moved between -85% and +165%. The zoom is 1.45X, which is relatively high for a DLPR projector. The optical block has been sealed perfectly, so unlike liquid crystal projectors, there will be no dust or dirt build-up on the panel over time that could degrade image quality.

High quality video processor by GENNUM GF9351
The renowned GENNUM GF9351, used widely by other companies, has again been used as the image processor. Originally developed for business use, this device is difficult to use effectively; however, based on previous experience with the VP-12S4 and VP-11S1, Marantz is now in the best position to bring out the full potential of the GF9351.

8 preset gamma, enrich 18 user memory

Fine menu for A full-featured menu for image adjustment
Marantz projectors are well known for providing good images “straight out of the box,” using the factory settings; however, in addition to three standard gamma settings, there are 5 gamma presets with intermediate image quality settings as well as an extensive Fine-tuning menu that enables the desired image settings to be achieved. Up to 18 memory slots are available to save the settings so they can be reloaded at any time to suit different source types.

A versatile array of input and control terminals
HDMI has now become the industry standard for connecting audio-visual home consumer electronics, and the different types of equipment users want to connect increases daily. As with previous models, VP-15S1 have two built-in HDMI systems. To support existing analog signal equipment, they also have two component video systems, as well as single separate systems for S video, video and D-Sub, enabling a wide range of equipment to be connected directly without need of an AV amplifier.

All key back lighting Remote Control
The remote control has a large number of keys to enable direct control without having to step through menus, but despite having so many keys, the remote is easy to operate in low-light environments, as every key has its own backlight.
