• Omnidirectional characteristic
• Clear and transparent sound reproduction
Getting Started
T he device to which the measurement microphone is to be connected must work with
phantom power (9-52 V/DC) to power the microphone.
T o avoid distortion or mismatching, which could damage the microphone or the con-
nected audio device, the microphone may only be connected to suitable microphone
inputs. Please refer to the connection data contained in the "Technical data" section.
T o connect the microphone, only use a suitable shielded microphone cable. Use of
other cables may lead to interference.
N ever point the microphone towards the sound exits of loudspeakers, as this may lead
to acoustical feedback that could damage the loudspeakers or the connected device.
• Mount the microphone clip onto a microphone stand.
• Insert the shaft of the microphone into the clip designed for the microphone.
• Switch off the device to which the microphone is connected.
• Connect the microphone input of your device to the XLR connector on the microphone.
• On your audio or measurement device, enable phantom power for the microphone.
• Turn your audio or measurement device on.
• Adjust the sensitivity of your audio device by using the corresponding input level control on the
microphone (see the instructions for the audio device).
Maintenance and Cleaning
This device is maintenance-free.
Please use a soft, dry or slightly damp cloth for cleaning.
