Defi Nitions; Features - Extron electronics CrossPoint 450 Plus Series User Manual

Defi nitions
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.)
Confi guration — One or more ties or one or more sets of ties.
Current confi guration — The confi guration that is currently active in the
switcher (also called confi guration 0).
Global memory preset — A confi guration that has been stored. Up to 64 global
memory presets can be stored in memory. Preset locations are assigned to
the input buttons and (where necessary) output buttons. All presets can be
selected from the front panel for either saving or retrieving. When a preset is
retrieved from memory, it becomes the current confi guration. All presets are
also accessible under RS-232/RS-422 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 confi guration consisting of outputs in a single room
that has been stored. When a room preset is retrieved from memory, it
becomes the current confi guration. The switchers support up to 10 presets
per room.

Features

Video (video BMEs) — All switchers input and output video on BNC connectors.
CrossPoint 450 Plus Wideband Video — These switcher BMEs input and output
wideband RGBHV or RGBS video. They can also switch RGsB, RsGsBs,
component/HDTV, S-video, or composite video.
MAV Plus Low Resolution Video — These switcher BMEs input and output
NTSC 3.58, NTSC 4.43, PAL, or SECAM video or HDTV video inputs.
Depending on the video format of the switcher system, these switchers can
distribute low resolution RGsB, RsGsGs, component/HDTV, S-video, or
composite video.
Bandwidth —
CrossPoint 450 Plus Wideband Video — The wideband switcher BMEs provide
a minimum of 450 MHz (-3 dB) video bandwidth, fully loaded.
MAV Plus Low Resolution Video — The low resolution switcher BMEs provide
a minimum of 150 MHz (-3 dB) video bandwidth, fully loaded.
Audio inputs (audio BMEs only) —
Stereo audio BME — Input and output balanced or unbalanced stereo audio on
3.5 mm, 5-pole captive screw terminals.
Mono audio BME — Input and output mono audio on 3.5 mm, 3-pole captive
screw terminals.
Audio input gain/attenuation (audio BMEs only) — Individual input audio
levels can be adjusted so there are no noticeable volume differences
between sources. Users can set the input level of audio gain or attenuation
(-18 dB to +24 dB) via the Ethernet link, RS-232/RS-422 link, or the front
panel.
