Description

The 4425 is a broadcast quality 270Mb/s SDI to component analog converter.

It has a re-clocked SDI output. 525 or 625 line SDI is automatically detected. Switches on the end of the unit select RGB or YUV output, SMPTE/EBU or Beta component levels, pedestal, color bar output, 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.
