USB measurement microphone

 

With this USB measurement microphone you easily perform high performance measurements with your PC.

Simply connect this microphone to a free USB port, no preamplifier, no external power no driver. It was never easier to measure with your PC.

This system uses capsules with the thread 60UNS. You can connect almost any capsule from world leading brands. e.g. Bruel&Kjaer, GRAS, PCB and others.

With common mechanical adapters you can use 1" or 1/4" capsules.   

The base package is equipped with a class 2 capsule (22mV/Pa)

The dynamic range is 20-111dB(A) 114dB peak

With our dynamic extension package you can increase the dynamic by 20dB to 130dB (133dB peak). With 1/4" capsules or attanuators you can reach significant higher level up to 170dB.

You can also connect class 1 capsules.

Features

Gain is controlled by the PC allowing absolute level calibrations
Requires no external power. Simply connect it to USB
The operating system recognizes this USB microphone directly. There is no driver required. You can use this USB measurement microphone with Windows, MacOS or Linux. This feature will protect your investment, since you not depend on updated drivers.

We offer this system with different options (different capsules or dynamic extension)

Common characteristics

Frequency range 10Hz-20kHz
Thread 60UNS
USB Audio class compliant
possible cable lengths: 5m with simple passive USB cables, 15m with active cables and 60m with special transceivers for regular CAT5 cables
The frequency response was measured electrically. The capsule was replaced by an capacitor. The curve does not contain the acoustical frequency response of the capsule.

 

Base package

The base package contains a 1/2" class 2 capsule with the following parameters

Sensitivity typ. 22mV/PA
Dynamic range 20-111dB(A) 114dB peak

Options

With the option extended dynamic you can measure up to 130dB (133dB peak). You will get a second channel with 20dB offset. You can record or measure both channels simultaneously. This offers a dynamic range which where up to now not possible for USB measurement microphones.

If you connect a 50mV/Pa capsule you will get the following dynamic range

17dB to 103dB in the base package
and 17dB to 123dB (126dB peak) with the extended dynamic option
The self noise of the amplifier and AD converter is 6.5dB(A)

You can reach significantly higher levels with 1/4" capsules.

The frequency response was measured electrically. The capsule was replaced by an capacitor. The curve does not contain the acoustical frequency response of the capsule.
