AES AUDIO CONNECTIONS
The 7720DAC-A4 converts unbalanced AES audio and has two BNC connectors for inputting unbalanced
AES signals compatible with the SMPTE 276M standard. The 7720DAC-A4-B converts balanced AES
audio and has two 3 pin terminal strips for inputting balanced AES signals compatible with the AES3-1992
standard. The input audio cables can be secured into the removable portion of the terminal strips using a
small screwdriver. The removable part of the terminal strip is then inserted into the rear panel.

ANALOG AUDIO CONNECTIONS
The 7720DAC-A4 has two 6 pin terminal blocks containing balanced analog audio that has been
converted from the input AES audio. The output audio cables can be secured into the removable portion
of the terminal strips using a small screwdriver. The removable part of the terminal strip is then inserted
into the rear panel. The left/right channels from the AES IN 1 input will come out the Analog Audio 1 and 2
outputs respectively. The left/right channels from the AES IN 2 input will come out the Analog Audio 3 and
4 outputs respectively.
