Audio output volume (systems with audio BMEs) — The audio volume of each
output can be displayed and adjusted through a range of full output to
completely silent, from the front panel or under RS-232/RS-422 or Ethernet
control.
Digital Sync Validation Processing (DSVP ™) (CrossPoint 450 Plus Sync BMEs) —
In critical environments or unmanned, remote locations, it may be vital to
know that sources are active and switching. Extron’s DSVP confi rms that
input sources are active by scanning all sync inputs for active signals. DSVP
provides instantaneous frequency feedback for composite sync or separate
horizontal and vertical sync signals via the switcher’s RS-232/RS-422 or
Ethernet port. The frequency information can be displayed on any control
system or in a Windows
® -based control program on a local-area network
(LAN) or Internet (IP) connection (fi gure 1-2).

RGB Delay (CrossPoint 450 Plus Sync BMEs) — A switcher that includes a
CrossPoint 450 Plus Sync BME can briefl y blank the RGB (video) output
while it switches to the new input’s sync source, and then switches the RGB
signals. This allows a brief delay for the display to adjust to the selected
input’s sync timing before displaying the new picture, which will appear
without glitches. RGB delay, also known as Triple-Action Switching
™ or
video mute switching, is user selectable from 0 to 5 seconds, in half-second
increments.
Rooming — Each switcher can be programmed to group multiple outputs to
specifi c “rooms”, allowing them to have their own presets.
