Introduction, cont’d

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 confirms 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 (figure 1-2).

RGB Delay (CrossPoint 450 Plus Sync BMEs) — A switcher that includes a CrossPoint 450 Plus Sync BME can briefly 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 specific “rooms”, allowing them to have their own presets.
