Mirage 22000/4000/6000User's Manual
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 an
channel—and 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.
CHANNEL -
A channel is a collection of measurements, locations and settings that
tailor a display 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, tint, size, etc., in order to customize and optimize the display
coming from 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 earlier
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
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.
NOTE: The Chan key may display a channel
list or not, depending on what you have
defined within the Menu Preferences menu
(see Menu Preferences later in this section).

In order to use channels (
you must first create them. 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 (press
channels in the projector are searched for matching input and signal parameters. If no
match to the incoming input signal is found in the currently defined channels, a new
channel is temporarily created based on factory-defined defaults for this signal. The
channel number assigned to this channel is the lowest available number from 01-99.
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 a signal
present.
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.
