Fig. 1-8 Connection of R&S UPZ to an Audio Analyzer
In professional audio applications, all signal lines are generally balanced in order to
avoid interference coupling. For this reason, the internal signal lines of Audio Switchers
R&S UPZ are balanced and equipped with the XLR connectors commonly used in
studio engineering. The pin assignment is defined and shown in
on page 15.
