module. It is possible to do analog to digital conversion between frames, so one end can be
analog and the other end can be digital/AES.
Each Adder II can accommodate one or two 12 VDC power inputs @ 3 Amps via 4-pin XLR or
terminal strip. Grass Valley’s ADAP-AC-04 is an acceptable external DC power supply.
Depending on version, there may be a third 12-18VDC input for intercoms.
If you require re-configuration of your Adder II system, it should be returned to Grass Valley.
Call our support department (see
Contact Us on page 37) and request an RMA (Return
Materials Authorization) number.
When removing the Adder II from the shipping boxes, check everything over for any
damage, including missing optical caps, bent metal or pins, and case scratches. Be assured
that the utmost care was taken in building and packing your Adder II, so report any damage
to the carrier and to Grass Valley.
