Osee DMA6800 Embedded Audio De-Multiplexer

The DMA6800 provides one to two channels with embedded audio SDI output, two or three channels of analog composite video outputs and two channels of balanced analog audio outputs.
The DMA6800 adopts the latest encoding technology that gains high quality video output.The 12-bit encoding handles variety of signal inputs, assuring the high quality of the output. The 8X oversampling and jitter removal technology ensure the accuracy of output signal.
