K2 Summit 3G Production Client
Able to Leap Tall Buildings in a Single Bound

Get ready to scale to new heights with the K2 Summit® 3G Production Client. Take complete control of your live event workflows and broadcast applications in style.

This production server can fly solo or team up with the K2 Dyno® Replay System or GV STRATUS® nonlinear media production tools for extra oomph.

K2 offers a rock-solid state of affairs—delivering speed and stability for your live event production. With an embedded OS and three levels of processing all neatly packaged to save on space, K2 Summit gets an 'A' grade across the board.

With bidirectional channel control, you can quickly switch between record and play. Individual channels can be software configured for additional functions as well as generation of low-resolution streams and proxy. If you've been channeling your energy in the wrong places, reach for the summit with K2 Summit 3G.

Plus, this Production Client really sets the standards with codec support in DV, AVC-I, MPEG 2, and DNxHD formats as well as providing you complete compatibility between HD and SD as standard.

K2 Summit 3G Highlights

K2 Summit 3G Production Clients are available in 2 or 4 channel models with internal or external RAID protected storage or connected to a large SAN system with up to 150 channels or more. Systems can easily be expanded with more storage, more channels or more bandwidth and compression formats can easily be added or changed within each client.

The K2 Summit 3G is the only video server that provides agile codecs enabling playback of SD or HD content seamlessly on the same timeline with any supported format (DV/DVCPRO, MPEG-2, AVC-Intra, and H.264/AVCHD). It automatically up-, down-, or cross-converts a clip to the desired output resolution providing full support for all SD and HD formats.

For generating quick highlight packages or simple playlists, often all that is required is simple dissolves between two clips. Each channel in the K2 Summit 3G has this capability built-in (most servers require two channels to do a mix effect). An integrated mixer dissolves between two clips or to a matte color.

To easily monitor each channel without extra equipment or desk space, the built-in Multiviewer displays all 4 channels on a standard VGA monitor with transport controls for recording, playback jog/shuttle, or stopping along with audio meters, clip name and other important data. Each channel has an on-air SDI output and an SDI monitoring output with timecode burn-in.

ChannelFlex doubles K2 Summit 3G's capability from four bidirectional channels to application-specific configurations equivalent to eight channels:

  • Record up to 8 camera feeds
