For sale is ONE (1) used SEA-8203A DA board in very good condition. Backplane is included though bottom two audio connectors should be a BNC - so not really sure if these backplanes would work. We have a few units for sale (1 per listing price). This is one of them. All others are in same condition.
The SEA-8203A 1x8 is a high quality HD / SD SDI equalizing distribution amplifier for all standard and high-definition SDI signals. With support for both standard-definition and high-definition signals, the SEA-8203A is a great choice for all SDI distribution. The SEA-8203A equalizes the incoming SDI signal, compensating for up to 300m of cable at 270Mb/s and up to 100m of cable at 1.485Gb/s.
