each aspect ratio. These channels use Custom size presets to achieve the selected 
aspect ratio.

Pixel Phase: Adjust pixel phase when the image (usually from an RGB source) still shows 
shimmer or “noise” after pixel tracking is optimized. Pixel phase adjusts the phase of the 
pixel sampling clock relative to the incoming signal. 
For best results, use a good test pattern such as a smooth gray consisting of a clear 
pattern of black and white pixels, or a similar “half on, half off” graphic image. Adjust the 
slidebar until the image...

Filter: The proper filter setting is automatically set for virtually all signals, and rarely needs 
to be changed. It applies a low pass filter for noise reduction in the incoming input signal, 
particularly for HDTV or SDTV. Applied in the analog domain before sampling, this filtering 
removes high frequencies and thus reduces pixel phase noise (note this also reduces 
signal bandwidth). Override only if standard pixel tracking and phase...

 Auto Input Level: Keep off for virtually all sources (default). Temporarily enter a check 
mark only if you are an experienced technician and you have an unusual source that 
you feel needs further color temperature and/or input level adjustment. After entering a 
check mark, wait for the six slidebar values to stabilize, then clear the check mark and 
exit. This compensates for incoming out-of-range drives (white) and black levels (black)...

 Peak Detector: The Peak Detector is a tool to assist with defining individual input 
levels, enabling you to accurately set the white balance for any particular source with 
the appropriate image. 
Enabling the Peak Detector activates a special operating mode for detecting only pixels 
that are considered black or white; all other levels are displayed as a mid-level gray. 
When used with a smooth grayscale pattern in which black and white...

primary color shows one optimized black band and white (or colored) band, the input

HOW LONG CAN I MAINTAIN BRIGHTNESS? The SC-1 can maintain your “Intensity” 
setting until the required power reaches the maximum rating for the lamp. The lower the 
setting, the longer it will take to reach this threshold and the longer you can maintain the 
desired brightness. Keep in mind that once the lamp power reaches its maximum wattage 
(see “Power,” above), this tracking is no longer possible. At this point, the lamp will 
gradually...
