3.4 Using Inputs and
Channels
Do I select an Input
or a Channel?
noTe: See Section 2, Installation and Setup, for details on connecting sources to the
projector.
The projector stores and automatically recalls up to 50 different channels (source setups) for a
variety of inputs. This memory feature allows you to define and conveniently use a wide variety
of customized setups rather than having to repeatedly re-configure the projector for different
presentations. Depending on what you have defined, each physical source connection (i.e., input
at the projector) can have several different channels associated with it.

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, and will automatically display an image according
to default settings for such a signal. In general, the image from the new source will be as
large as possible without losing its aspect ratio. This and other default Picture Adjustments
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 below). Using one of the
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.
noTe: Inputs 7 and 8 require the Dual SD/HD-SDI module in either of the projector's option
slots. For their selection, see also 3.2 Using the Remote or Built-In Keypad.
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,
aspect ratio, 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, or one signal may simply vary from another
signal used previously through the same input location. 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 2-digit channel, such as
distinct channels available for the same input, any of which can be selected by using the
key on the keypad followed by the 2-digit channel number.
