Meridian Audio LD100/LD100U manual Image Sharpness Controls

Every LD100 is subjected to an intense battery of QC and environmental tests. Then each unit is re-tested and re-calibrated for optimum performance. The component parts used in the LD100 are the finest available, ensuring long term consistent per- formance and reliability. This unique, quality oriented “Faroudja touch” can also

be seen in the design of many of the LD100’s controls and features.

6)Brightness Level – Known as “Set-up” in the broadcast industry, the BRIGHTNESS control is used to set up the background black level. Pull the knob out and turn fully counter clockwise until the picture goes dark. Then rotate the con- trol clockwise until the black areas in the picture just begin to go gray. Turn the control back counter clockwise until the gray just goes to black. This is the optimum setting.

7)Contrast Level – As the BRIGHTNESS control sets the background black level, the CONTRAST control sets the foreground white level. First set the BRIGHTNESS level as above, then pull out and rotate the CONTRAST level clockwise, start- ing at the full counter clockwise position, until the white areas of the picture are clearly obvious.

8)Color level – With the Color control pressed in, the LD100 uses its internal AGC, (Automatic Gain Control) to set the color level. Pull the knob out and starting from the full counter-clockwise position, rotate clockwise for increased color sat- uration. This is a subjective setting, there is no right or wrong. Simply adjust for the most pleas- ing color level.

9)Tint – Also known as “Hue” or “Phase”, pull the knob out to adjust to your personal taste, partic- ularly in flesh tones. Adjusting the tint control shifts the picture towards the green or red areas of the color spectrum. Tint is only active in the video or Y/C input modes. With the control pressed in, the LD100 is in the Auto-Tint mode. The Auto-Tint mode is achieved by using internal phase comparison techniques to automatically display colors as intended.

IMAGE SHARPNESS CONTROLS (2)

The two rotary-style Image Sharpness controls, NOISE REDUCTION and DETAIL LEVEL, work together to sharpen edge transitions for a “punchi- er” picture. The proprietary bandwith expansion cir- cuitry contained in the LD100 is critical to its spec- tacular performance. Typical line doublers produce a flat, soft picture. The LD100’s Image Sharpness cir- cuitry improves the sharp line and edge transitions making for clearer, more vivid video images. This is accomplished with the two controls working in tan- dem, without adding video noise or digital artifacts which could otherwise degrade the picture.

10)Noise Reduction – After setting the detail level (11), the noise reduction control is then used to remove any residual noise that may be added during the Image Sharpness process.

11)Detail Level – To set the detail level start full counter clockwise and add detail until the edge transitions just begin to sharpen.

12)Digital Filter – The Digital Filter eliminates compression artifacts generated by video sources transmitted via a digital compressed path and should not be used with conventional video sources.

13)Freeze On/Off – Press to capture the current picture displayed on the screen. Press again to return to normal, active video. The freeze mode digitally captures the incoming video signal and holds it for critical viewing and adjustment. This feature allows you to optimize the LD100 pic- ture controls on a still, constant image of your choosing.
