CrossPoint / MAV Matrix Switchers • Introduction
Audio input gain/attenuation (audio models) — 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, either serial port link, or the front panel.
Audio output volume (audio models) — 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 serial port or Ethernet control.
Digital Sync Validation Processing (DSVP™) (CrossPoint) —
Incriticalenvironmentsorunmanned,remotelocations,itmaybevitalto

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 serial ports or Ethernet
port. The frequency information can be displayed on any control system
or in a Windows

RGB Delay (CrossPoint) — ACrossPointswitchercanbrie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
specic“rooms”,allowingthemtohavetheirownpresets.
