BALANCED INPUT
:
PA and SA (Stage Announce) OUTPUT CONNECTIONS
The PA and SA output signal is carried out through a XLR-3-32 male connector. The output is
balanced, with a nominal impedance of 100
Ω
. The next list shows the input pins correspondence
as A.E.S recommends:
PA OUTPUT - XLR-3-32
PIN 1
0 V
PIN 2
HOT (+)
PIN 3
COLD (-)
The output connection depends on two factors, the first is the type of input signal balanced or
unbalanced, and the second the ground configuration of the sound destination unit (floating or
ground-referenced). The next pictures show some of the different possibilities of connection,
relying on the type of output signal, balanced or unbalanced and according to the equipment’s
ground configuration (floating or ground-referenced).
In the next diagrams, we use the following symbols:
