Definitions
The following terms, which apply to Extron matrix switchers, are used throughout
this manual:
Tie — An input-to-output connection.
Set of ties — An input tied to two or more outputs. (An output can never be tied
to more than one input.)
Configuration — One or more ties or one or more sets of ties.
Current configuration — The configuration that is currently active in the
switcher (also called configuration 0)
Global memory preset — A configuration that has been stored. Up to 32 global
memory presets can be stored in memory. Preset locations are assigned to
the input buttons and (where necessary) output buttons. Up to 20 or 32
(depending on the number of input and output buttons) presets can be
selected from the front panel for either saving or retrieving. When a preset
is retrieved from memory, it becomes the current configuration. All models
have 32 presets; on models with fewer than 32 input and output buttons,
preset numbers that are too high to be available from the front panel are still
accessible under serial port or Ethernet control.
Room — A subset of outputs that are logically related to each other, as
determined by the operator. The switchers support up to 10 rooms, each of
which can consist of from 1 to 16 outputs.
Room memory preset — A configuration consisting of outputs in a single room
that has been stored. When a room preset is retrieved from memory, it
becomes the current configuration.
Input and output buttons
If the switcher has fewer inputs or outputs than input or output buttons, only
the buttons for which the switcher has an input or output perform the function
of selecting and identifying that input or output.

Input buttons — The input buttons have two primary functions (•) and five
secondary (❏) functions:
• Select an input.
• Identify the selected input.
❏ (Input 1 only) With the Output 1 button, select I/O Group mode. See
“I/O grouping” on page 3-21.
❏ Select a preset. See “Using presets” on page 3-28.
❏ (CrossPoint 450 Plus switchers, Input 1 through 10 only) Display the
RGB delay. See “Setting RGB delay (CrossPoint 450 Plus Switchers)” on
page 3-26.
❏ (Audio models) Display the output volume level. See “Viewing and
adjusting the output volume (audio models)” on page 3-41.
❏ (Input 1 and Input 2 only) Toggle background illumination of the
buttons off and on. See “Background illumination” on page 3-50.
