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 5 or 10 meter ASD Cables together in se-

ries. The ASD technology supports accurate data communica-

tion 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.
