D&A AUDIO AND VIDEO RACKMOUNT

An modular range of digital and analogue video and audio cards and frames for the international broadcast market

 

The D&A distribution system is designed to the highest specification and meets all relevant international standards. Digital & Analogue video and audio modules can be mixed within a frame to satisfy a wide variety of interfacing requirements. Up to 14 modules can be housed in the 3301 3U rack-mounting frame with a single power supply, 12 in the 3302 3U frame with dual power supplies or 3 in the 3100 1U frame.
