The D8204A is a four-output digital audio distribution amplifier, designed specifically for use in 75 Ohm unbalanced coaxial cable installations. It uses BNC2 rear termination modules, which comes included as part of the D8204A+RM set. With an onboard digital-to-analog converter, the D8204A also provides two stereo analog audio outputs. Features such as cable equalization and data reclocking allow the unit to reliably recover the incoming digital signal. Lock, Confidence, No Lock and equalizaton LED indicators are all visible from the front edge of the card. Located at the top edge of the card is the EQ insert switch, which automatically activates the cable equalization without having to set any jumpers.
