How To Select An Input Or A Channel - Christie J Series User Manual

3.3.1 How to Select an Input Or a Channel

Input: An input is a source physically connected to the projector. I
input slot it is connected to.
Channel: A channel is a collection of measurements, locations and settings that tailor the display of a signal to
your specific needs. Since source types and applications can vary greatly, you will likely want to adjust and
define a wide variety of parameters, such as brightness, contrast, size, etc., in order to customize and optimize
the display from or for a particular source. For example, the display settings you choose for a VCR source may
be very different from those you choose for a high-resolution computer source.
Once you have adjusted a display parameter, such as pixel tracking or contrast, all current settings are
collectively stored in the projector's memory as a unique two-digit channel, such as 09. You can have
numerous distinct channels available for the same input, any of which can be selected by using the C
key on the keypad followed by the two-digit channel number.

Switching Inputs: There are 3 methods for selecting an input:
1. Press the INPUT key. This will display a list of the 4 slots,
with the card type and input signal type in each slot. The
currently selected input for the main image will be
highlighted. Scroll up or down through the list and press
ENTER to make a new selection. Press the INPUT key again to show the list and allow the selection for
the PIP/Secondary image. Repeatedly pressing the INPUT key will toggle between the main and PIP/
Secondary image.
2. Press the appropriate direct SLOT key to quickly display one of the inputs on the selected slot to the main
image. This will not bring up any menu selection, and is only applicable for the main image.
3. Use the following menu options to select the source of the image for the main or PIP/Secondary image.
Menu > Input Switching and PIP > Main Input and Menu > Input Switching and PIP > PIP Input.
The image will be displayed according to the following:
• If it is the first time you have used the source/input (or if you used the input but did not define a channel by
adjusting anything), the projector will recognize the new input signal based on its frequencies and polarities,
automatically displaying an image according to default settings for that signal.
• In general, the image from the new source will be as large as possible without losing its aspect ratio. This and
other default image settings depend on the incoming source.
• If you used the source once before and changed a display parameter, such as contrast, V-Position, etc., then a
channel was automatically created and still exists in projector memory (see CHANNEL below). Using one
of the input or slot keys will automatically recall this channel, all its setup parameters, and update the display
accordingly.
• If more than one channel exists for the input, the image will be displayed according to the setup parameters
for the first channel with matching characteristics.
