Ross Video DMX-8259-4C-R2C 4-Channel 3G/HD/SD-SDI Analog Audio De-Embedder

The Ross Video DMX-8259-4C is a high quality program audio de-embedder capable of de-embedding up to 8 analog audio channels from an 3G / HD / SD SDI signal. Audio proc amp control on each channel allows for audio processing with gain of ±10dB, audio delay up to 1 second and channel invert.

The DMX-8259-4C /-8C supports any channel assignment to the discrete inputs and can re-map any of the existing embedded channels. Various configuration options, including

internally generated patterns and tones, are available for audio and video output scenarios should a loss of input occur.

The DMX-8259-4C features 4 analog outputs.
