The new GV Korona K-Frame V-series systems are specifically designed for low- and mid-range broadcast and media applications, where compromising on performance is not an option. GV Korona K-Frame V-series systems are available in three system packages, starting at 16×8 with 1, 2 or 3 M/Es (plus 2 VPEs for additional keying and mixing power) and a complement of licenses, for exceptional value and incredible power.

The small footprint of the GV Korona K-Frame V-series is ideal for smaller stations, sub-studios, mobile environments, corporate, sports venues, educational, government and houses of worship production facilities. With its modular design for simple scalability and serviceability to its handling SD/HD and the ability to produce in 3G/1080p with no loss of functionality and 4K UHD with a simple license upgrade, it is ready for anything.


Key Features:

K-Frame V-series

  • Supports 3G-SDI without compromising any other features
  • VPEs offer four full function keyers, resizers and a mixer for all the keying power you will ever need
  • Supports 2160p for UHD-1 productions with up to 3 M/Es
  • Using K-FRM-IO-CONV-V every path supports frame sync and up/down/crossconversion between SD, HD, 1080p, quad-link 4K UHD 2SI or SDQS, plus gearboxing of 12G-SDI
  • Modular design, buy only what you need today and reconfigure/upgrade as your needs change
  • AIMS-compliant IP I/O option protects your investment
  • Media Ports for non-SDI production signal types
  • Optional iDPM for added 3DDVE capabilities
  • Optional KSP GUI control software can be used instead of, or in conjunction with, hardware panels

GV Korona Panel

  • Fully integrated multitouch menu system and innovative touchscreen in transition area
  • Same familiar user interface and power as Karrera, but in a smaller form factor
  • Compatibility with all K-Frame series frames — can be deployed as a second control panel for large events
  • Just like any K-Frame switcher, the ability to load shows from Kayenne or Karrera show files
  • No compromises on enterprise features, even with such a competitively priced product
  • Training costs can be spread across the entire GV production switcher range (Kayenne, Karrera or GV Korona) — learn one panel, learn them all!
