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.
