The CV-300A HD/SD-SDI to Component Converter with Audio Support provides high quality 12 bit
conversion between SDI digital video input and component analog video output. Plus, with two extra retimed SDI
loop outs, CV-300A can also be treated as an advanced SDI splitter. The CV-300A supports both SD-SDI and
HD-SDI formats including SMPTE 259M, SMPTE 292M, and SMPTE 296M. Built-in 24 bit audio conversion up to
114dB 8 Channel DAC audio conversion offers a complete video and audio between SDI and analog video
component and balanced and unbalanced audio outputs at the same time!
