46 Control Panels for X75 Systems Installation and Operation Manual
Chapter 2: Operation via Front Panel Controls
The directional softening/sharpening filter can be used in various
applications. For example, the softening filter can be used as a
compression pre-filter to reduce mosquito noise, and the sharpening
filter can be used to enhance picture appearance. The Soften/Sharpen
control provides this function; a negative value achieves a softening
effect, and a positive value results in a sharpening effect. While
adjusting these controls, the Split Screen feature may be used to
compare the filtered video against unfiltered video.
The overall filter delay is approximately 1 line when the Minimum
Delay parameter is set to Yes, and approximately 1 field when set to
No. The overall performance is slightly better when Minimum Delay is
set to No.
HD NR/Enhancement
The HD digital noise reduction and enhancement controls are included
as a standard feature with the HD submodule and may be applied to the
X75HD's HD outputs.
When equipped with the X75OPT-NR option, for the up-converted HD
output signal, you can use either (or both) of the SD or HD noise
reduction functions. To use the SD NR/Enhancement feature in this
case, set the SDNR Insert parameter to the appropriate SD video input
as described in the previous section.
Option
The Option control panel shortcut allows quick access to certain
parameters, some of which become enabled with the purchase and
installation of various optional modules and upgrades.
To access the list of Option parameters, press the Option button, and
then select one of the following items:

for alarms on your network of X75-RCP-enabled devices. For each
