BLACK BOX PRO

AUDIO

MEASUREMENT

 

 

Black Box pro is one of very compact system that can do almost of all audio measurement.

Its can do almost everything that you can imagine to get what you want in one small package.

And because of Plug-in usb, that can be use to any computer system without any system calibration, its will very portable to use with any desktop or laptop.

 

What Black Box Pro can do:

  1. Real time analisys of spectrum.
  2. Real time frequency response measurement
  3. Real time impulse response measurement
  4. Real time impedance measurement
  5. Can do measurement of LCR (LCR meter)
  6. Can do Thiele small estimation
  7. Ossiloscope
  8. SPL Reading regarding of mic type with SQ3 is 129 db
  9. Etc

 

 

Black Box Pro Measuring Systems is consists of :

 

1. Black Box Microphone type SQ4

 

PRODUCT DESCRIPTION

 

MIC SQ4 are very precision condenser electret microphones perfectly suiteable for laboratory and on-field acoustical measurements. Their frequency response is individually tested against specifications and the sensitivity value is at about 17mv/pa.

MIC SQ4 can be directly connected to your ANY of your system’s input (with proper mic amp).
