Connect the output terminals of the microphone to a device that has a microphone
input (balanced input) compatible with a phantom power supply.
The output connector is a Euroblock connector with polarity as shown in the figure
below.
Use STP cables to connect from the mounting box RJ45 jacks to breakout cables.
Output terminals
The product requires 11V to 52V DC
phantom power for operation.

• Output from the microphone is low impedance (Lo-Z) balanced. The signal ap-
pears across the pair of each output Euroblock connectors on the RJ45 breakout
cables. Audio ground is the shield connection. Output is phased so that positive
acoustic pressure produces positive voltage on the left side of each Euroblock
connector.
• MIC1 is “O” (omnidirectional), MIC2 is “L” (figure-of-eight) positioned horizontally
at 240°, MIC3 is “R” (figure-of-eight) positioned horizontally at 120°, and MIC4 is
“Z” (figure-of-eight) positioned vertically.
