The 8945EDA module is a single SD/HD
equalizing distribution amplifier. It provides
eight outputs 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.
