The 8945EDA-D module is a dual SD/HD
equalizing distribution amplifier. It provides
four outputs for each of its two inputs and can
equalize up to 125 meters of Belden 1694A
cable for HD-SDI. It can be used to distribute
either SD-SDI or HD-SDI, making it ideal for
mixed-format applications or installations
where an upgrade is planned.
