The Datavideo DAC-30 is a broadcast quality bi-directional SDI, DV, Component, Composite, S-Video format converter designed for use with TV studio equipment. The unit also offers AES / EBU audio conversions.

Featuring Component (YUV or Y/B-Y/R-Y), S-Video (Y/C), Composite video and two channels balanced/unbalanced audio for bi-directional analogue to SDI, analogue to DV and analogue to analogue conversion, all outputs work simultaneously for flexible applications.

Front panel controls allow audio level control and VU metering of audio levels. Balanced audio signals are also converted to unbalanced signals for standard amplifier monitoring. Build-in RS-422A interface for controlling VCRs via the DV connection from an NLE system, such as Avid, Adobe or Final Cut Pro.

The Datavideo DAC-30 is an ideal SDI in/out solution for any DV interface in a studio environment.
