Kula AV 1 M/E Production Switcher

Kula AV is a powerful, multiformat all-in-one system that mixes SDI video (with or without embedded audio) and AES digital audio, and has built-in multiviewer capability. Designed to support the needs of smaller operations, this compact system allows a single operator to have everything they need at their fingertips for compelling corporate, house of worship, and small venue productions such as sports, events, conferences and education.


Kula AV 1 M/E Production Switcher

In addition to Kula’s recognized 1080p production switcher performance, the Kula AV 1 M/E Production Switcher simplifies configuration and control with Grass Valley’s FormatFusion3 technology, which auto-senses and seamlessly converts any combination of SD, HD and 1080p to the required output for unrestricted mixing of video signal types across all inputs and output. A graphics interface allows quick editing and loading of high-end graphics. The system’s integrated audio mixing capabilities include embed/de-embedding, clean and quiet audio switching, and audio-follow-video mode. With Kula AV, professional-looking productions are easy to achieve.

All of these features are packed into a compact 2 RU mainframe with a convenient 19-inch wide rackable control surface suitable for fly-packs. Also included in the package is the Mav Audio Fader module. Kula AV may be a compact production switcher but it packs a huge punch.
