3 Overview
The VP-4x4Kis a true 4x4 matrix switcher for computer graphics (up to and
exceeding UXGA) signals and balanced stereo audio signals. The VP-4x4Klets
you simultaneously route any or all of the four inputs to any or all of the four
outputs.
In addition, the VP-4x4Kfeatures:
•A video bandwidth of 400MHz that ensures transparent UXGA performance
•DC coupled inputs and outputs
•A selectable delayed switching mode (ranging from 0 to 3.5sec1
•Audio gain control for the inputs and the outputs
) for clean
transitions (seamless switching) when switching between non-genlocked
sources
•Audio-follow-video and breakaway options
•Storing and recalling setup options
•A TAKE button for precise switch control that lets you execute multiple
switches all at once
•A LOCK button to prevent tampering with the front panel
•The ability to automatically detect connected input signals (the respective
button illuminates in green)
•Our innovative integrated sync processing; KRISP™ technology that lets
you achieve a sharp, stable image when the sync level is too low, by
restoring the sync signal waveform
Control the VP-4x4Kusing the front panel buttons, or remotely via:
•RS-485 or RS-232 serial commands transmitted by a touch screen system,
PC, or other serial controller
•The Kramer RC-IR3 infrared remote control transmitter
•The ETHERNET
To achieve the best performance:
•Connect only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noise
levels (often associated with low quality cables)
•Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your Kramer VP-4x4K
away from moisture, excessive sunlight and dust
