Microphone Description
Connecting to XL2
Microphone plugs directly into the XL2
The XL2 automatically reads the electronic data sheet of the
connected microphone as follows:
Connect the measurement microphone to the XL2. •
Switch on the XL2. •

The XL2 reads the electronic data sheet of the connected
microphone during a brief initialization process prior to the
first measurement.
Microphone Connection via the ASD Cable
The NTi Audio measurement microphones can be connected
with an ASD Cable to the XL2 Analyzer for measurements at
remote locations or for reducing acoustic reflections. The elec-
tronic data sheet is transmitted via the XLR connector’s hous-
ing. Do not touch this during the brief initialization period to
ensure the complete data sheet is recognized by the XL2. The
automated sensor detection does not disturb any measure-
ments. You may join up to 4x ASD Cables together in series.
The ASD technology supports accurate data communication up
to a combined cable length of 20 meters (= 65 feet).
Microphone Connection via a professional Audio Cable
For distances longer than 20 meter (= 65 feet) use a high qual-
ity, low capacitance standard professional audio cable. The mi-
crophone sensitivity has to be entered manually into the XL2
Analyzer.
Alternatively connect the microphone first directly to the Ana-
lyzer. The XL2 reads the sensitivity and remembers this value.
Afterwards connect the audio cable.
