Loudspeaker measuringsystem 24bit/96kHz

Measuring set for use with ARTA

For building / measuring speakers , there are many programs to help you with this. ARTA and REW are best known and used. However, a problem for many is that it's not really clear which sound card and microphone are very suitable . For this RumoH has assembled this set

For loudspeaker measurements with ARTA, REW and other software requires a good sound card, now there is often unclear which soundcard works good, the internal sound cards often leave much to be desired, especially for laptops. The logical step would be a good external soundcard. Besides a good soundcard you also would need some sort of jig to measure impedances or measure Thiele/Small parameters.

RumoH has partly due to the many questions about ARTA and REW created a set that has been extensively tested. Our goal was a measuring set wich is mobiler and very handy and has to work with all the known loudspeaker measuring software, free or licensed.

The Measuring set

For extreme mobility the included soundcard has no need for external power, just running from your USB port. The 24bit/96kHz DAC provides enough bandwith to make very accurate measurements. Phantom power supply is also onboard wich is needed for the microphone in this set. To connect an amplifier there are two RCA outputs, this way measuring and listeningrn is done without changing plugs!

The microphone supplied has its own specific calibration file (which can be downloaded from the manufacturer). The microphone is in a sturdy plastic box including a microphone clip. To connect the microphone a 6m microphone extension cable is provided.

The impedance measuring cable is such that there can no errors be made in the connecting, also measuring is truly made very simple. The impedance measurement is carried out without the use of an additional power amplifier.

Also very handy is our instructions supplied to install and setup ARTA for measuring. This guide also describes how you can very quickly make a measurement with ARTA without having to read through the entire manual of ARTA.
