Wolf cinema REF-700 Owner's Manual page 50

For some types of video, you can override the setting. The control is disabled for other types of video (and all
graphics sources). Generally, if black appears crushed when brightness = 50, choose "Enhanced 0 IRE". If black
appears excessively elevated, use "Video 7.5 IRE".
COLOR: This slidebar adjusts the Color Temp Adjust level, i.e. the amount of color in a video image. Lower settings
produce less saturated colors — for example a setting of "0" produces a black and white image. If the color level is
too high, colors will be overpowering and unrealistic.
TINT: This slidebar adjusts the red/green color hue for true color reproduction of video signals connected to
INPUT 3 or 4 of the projector. For best results, adjust tint while displaying an external color bars test pattern —
otherwise, it is recommended that tint remain at its default setting.
CHROMA LUMA DELAY: This control affects any incoming composite or S‐video signal, delaying the luma signal
(intensity) in relation to the chroma (color). In the image, increasing the luma delay will move luma (seen as a
shadow where colors overlap) to the right slightly, with colors remaining in place. Decreasing this delay will move
the shadow slightly to the left. If necessary for your current source, adjust so that no shadows occur with adjacent
colors.
Input Levels — SUBMENU
NOTES: 1) Because the projector automatically
optimizes input levels for all but the most unusual of
sources, it is recommended that only experienced
users use the Input Levels submenu. 2) Before
beginning, check that overall contrast and brightness
settings are near 50 and that color temperature is
properly set up on an internal grayscale test pattern.
3) There must be at least 2 consecutive white pixels
present in the image for proper "Auto Input Level"
function. Leave this control off after use.
Good RGB or input levels — that is, the drives and black levels for each of the three colors, red, green and blue —
insure that images from analog sources other than decoded video have maximum contrast without crushing black
or white. By default (and in a "Quick Setup"), the projector automatically determines the best input levels by
monitoring image content and adjusting the controls appropriately — further adjustment is typically not required
to obtain proper blacks or whites.
NOTE: This automatic adjustment requires at least 6‐12 consecutive white pixels in the image. Without these
pixels, input levels may produce skewed colors, particularly in non video images. However, for a very unusual
source exhibiting one or more overly high black levels (typically caused by a noisy source causing black level
spikes), an experienced user may prefer to use the Input Levels menu (shown above). These adjustments, which
together serve as a calibration process compensating for differences in sources and cabling, enable an experienced
user to perfect the source image input levels and eliminate the "overshoot" and "undershoot". Note that Input
Levels are of limited use with digital signals, but do offer some ability to tweak poorly mastered source materials.
