ISM 482 Integrated Scaling Matrix Switcher • Operation 22
Auto Imaging and Auto Memories submenu
The Auto Imaging and Auto Memories menu provides a means to turn the auto imaging and
auto presets features on or off globally.
If auto imaging is set to on, the ISM automatically sizes and centers the selected input to fill
the screen when a new frequency is input. If auto imaging is set to off, the ISM automatically
sizes and centers the selected input only when it is commanded using the input button (see
Auto imaging an input on page 14). Rotate the Adjust knob to toggle auto imaging on
or off for all input selections.
The auto memories feature saves and recalls centering and sizing information, based on the
input frequency. With some control systems, the delay involved in recalling the memory can
be a problem, so it may improve system performance to turn auto memories off. Rotate the
Adjust knob to toggle auto memories on or off.
Enhanced Mode submenu
The Enhanced Mode submenu provides a means to turn enhanced mode on or off.
Enhanced mode is an automatic gain control for S-video or composite video input signals
scaled and applied to an output. If the input signal level is too weak, the signal gain is
increased; if the input signal level is strong, the signal gain is decreased.
Use either the Adjust or Adjust knob to turn on enhanced mode for neither output (off
for both), output 2, output 1, or both outputs. The default is Off for both.
NOTE: Enhanced mode is effective only for S-video and composite video input signals.
Pixel Phase submenu
The Pixel Phase submenu displays and lets you set the pixel phase, which is the timing
of the digital scaler’s sampling. Sampling at the optimum pixel phase results in a brighter
scaled output.
Use the Adjust knob to select the pixel phase for output 1 from 0 to 31. The default is 16.
Use the Adjust knob to select the pixel phase for output 2.
PAL Film Mode submenu
The PAL Film Mode submenu lets you turn PAL film mode on and off for the selected input.
The PAL film mode should be used for a video source that is PAL video that originated from
film. PAL film mode applies video processing algorithms that optimize the conversion of
video that was made with the 2:2 pulldown (PAL video from film) process.
Use either the Adjust knob or the Adjust knob to select On or Off. Select other inputs
as necessary to configure.
Reset submenu
The Reset submenu resets all ISM 482 settings and adjustments to the default values and
erases all presets. The front panel reset performs the same functions as the

Reset the switcher by pressing and holding the Black/Mute button while this submenu is
active. The LCD displays Unit Reset to Factory Defaults when the reset is complete.
Release the Black/Mute button.
