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, 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
.
You can have
numerous distinct channels available for the same input, any of which can be selected
by using the
Channel
key on the keypad followed by the 2-digit channel number.
Shown at right is a sample channel list as would
be available from
Channel
. This is typically called
the channel list.
NOTE: The
Channel
key may display a channel list
or not, depending on what you have defined for
“Display Channel List” (see Menu Preferences
later in this section).
In order to access channels by using
Channel
on the
keypad, you must first create the channels. See
below.
To use a new source with the projector, a new channel must be added to projector
memory so that the projector will respond properly to an input signal from that source
in the future. A new channel can be created automatically, as described here, or it can
be copied from an existing channel and then edited as necessary (see Copying or
Deleting Channels later in this section).
When you select a direct input (
Input 1
,
Input 2
,
Input 3
,
Input 4
, or
Input 5
), the projector’s
existing channels are searched for matching input and signal parameters. If no match
to the incoming input signal is found, a new channel is temporarily created based on
factory-defined defaults for this type of signal. The channel number assigned is the
lowest available number from 1-50.
NOTES: 1) An automatic channel will be discarded unless one or more of its
parameters are changed, and will not appear in the channel list (see below). 2) If two
channels have the same distinguishing source characteristics except for the reversal
of sync connectors (i.e., H-sync and V-sync, are switched), they are still defined as
distinct channels. 3) You cannot define a new channel without an incoming signal.
If the incoming signal does match an existing channel, the image will be set up and
displayed as usual according to the parameters currently defined for that channel.
