Figure 8-8: Analog Input and Link XLR Connections
When linking analog inputs of several PLMs, consider that the drive capability of
the source’s output stage (e.g. mixing console) may be limited. Generally it is
inadvisable not to parallel link more than four inputs. If more links are required,
use a good quality balanced audio line driver or distribution amplier.
8.2.2 Analog & AES3 XLR Wiring and Pin Out
All XLR connections are wired to IEC268 as shown in Figure 8-9.
