The new version of the DATS tester incorporates an update that improves stability and overall reliability and eliminates start-up time. In addition, it includes a new interface with signal generator, possibility to create data libraries, etc.

The DATS V2 allows you to measure all the parameters related to a loudspeaker with speed, efficiency and simplicity. Plug the USB interface into one of the ports of your PC computer, install the provided measurement software, and you are at the head of a real acoustic testing and modelling laboratory that has little to envy to professional infrastructures, accessibility in addition... For example, it only takes a few seconds for DATS to draw the electrical impedance curve of a transducer developed from 30,000 measurement readings, and barely more to establish a record of the characteristics of the same loudspeaker in the open air. It can even go so far as to inform you about the 1kHz inductance of your speaker filter, or even represent the variations in independence of a multi-channel system.

Its accuracy makes it an essential tool for those who wish to virtualize and evaluate the most complex acoustic configurations before they are implemented. The only limit then becomes your imagination!

Features :

• Calculation of the electrical impedance curve from the characteristics of the loudspeaker in the open air.
• Calculation of the frequency response over a range from 1Hz to 20kHz.
• Calcul of the SPL level (1W / 1m)
• Thiele & Small Parameter Calcul :
  • Qes : Electrical value indicating the damping of the electrical circuit at its resonance value Fs.
  • Qms : Mechanical value indicating the damping of the mechanical circuit at its resonance value Fs.
  • Qts : Total damping, paralleling of Qms and Qes values.
  • Vas : Air volume equivalent to speaker suspension or Cms.
  • Fs : Resonance frequency of the loudspeaker in the open air.
  • Mms : The moving mass of the system, including the mass of air displaced by the transducer.
  • Re : Resistance of the moving coil in direct current.

Evolution compared to V1 :

• New software interface.
• New signal generator with waveform, amplitude and frequency selection.
• New oscilloscope and generator compatible with other audio interfaces.
• New method of calculating the Vas from the Mms.
• Faster module start up.

Computer requirements :

• Intel Pentium III processor at 500MHz minimum (1GHz PIV recommended).
• 1x compatible USB port 1.1 or higher
• Compatible OS: Windows XP, Vista 32, Vista 64, Win 7, Win8.

Note: On Windows 10, in case of an error during the autocalibration sweep, go to the Windows 10 privacy settings and allow applications to use the microphone.
