Using Inputs And Channels; Do I Select An Input Or A Channel - Runco Video Xtreme VX-40d Owner's Operating Manual

Section 3: Operation
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.
NOTE: Channels are pre-configured at the Runco factory for use with the DHD
Controller, and do not necessarily need to be changed. The following information
is only necessary if other sources are connected directly to the projector.
INPUT — An input is a source physically connected at the projector. Input describes the
➤
source signal according to which input slot it is connected.
SWITCHING INPUTS — Press the appropriate "direct" key — Input 1 , Input 2 , Input 3
, Input 4 , Input 5 or Input 6 to quickly display from one of the six inputs connected. 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, 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 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 below). Using one of the Input keys will automatically recall this
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.
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, 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 0 9 . 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.
