ATB PC Pro
The ATB PC Pro Measuring system is a professional Audio Analyser. The Windows program is combined with the computer’s soundcard, the measurement microphone, the Test-Box and the DVD (CD) for the signals forms an exact and extensive measurement system. The applications for the ATB PC Pro are the speaker development, room acoustic optimise, the installation of car sound systems, the setting of Surround reproduction systems and the noise analyser.
The following measurements are available:
• SPL Electric and acoustic phase frequency response
• Impedance measurement
Thiele-Small with voice coil indutance
• Step response
• Distortion THD as plot
• Distortion IMD
• RMS (sound) level meter
The Windows measuring program corresponds to a small ATB precision program offering all the functions of the Windows operating system. Notebooks and external USB soundcards prove to be ideal for this field of work. For the high precision of the measurement there is an automatical calibration of the soundcard.
For CAD or calculation program or data base the ATB PC data can be exported in many formats. The export is to MLSSA, LAUD, IMP and CLIO file.
is the including measurement microphoneMC1. The microphone is connected to the MIC input of the soundcard. The frequency response is very flat in the
range from 20Hz – 20kHz. Therefore, there is no need of a correction. The plot shows the response of the microphone.
There are following measurement functions:
• Continued measure, continued measure+ for the setting of devise
• Continued measure with averaging, continued measure with averaging+ for anechoic measurement in room or automotive and for the power distribution of a speaker

The Thiele-Small measurement is for testing the speaker parameter. The parameter are needed for the calculation of a box.
The Thiele-Small program is the professional from the ATB precision. There are a lot of speaker companies who using it.
The measurement has many error messages to show that the parameters are not correct. So also the not experienced user will get the right parameters.
The program has a complex calculation for the voice coil inductance. There for the measurement is better than sheep instruments or programs.
The phase measurement is not influenced from the user so there is always the right phase plot. The acoustical phase measurement is comparable.
For subwoofer sound systems there is to measure the impulse of the Subwoofer and the satellites.
Therefore, the phase control of the subwoofer could be set in the way, that both speakers have the same impulse.
