Description

The 4424 is a broadcast quality 270Mb/s SDI to composite analog converter.

It has a re-clocked SDI output. NTSC or PAL is automatically detected. Switches on the end of the unit control the output of the built-in test patterns, and blanking of the vertical blanking information.

It is housed in an extremely compact and rugged aluminum case ideally suited to both studio and portable applications.
