How to Measure an RTA Spectrum
The XL2 provides an RTA (Real Time Analyzer) with which you can measure the audio and acoustic
response of your system.
For example, you can compare the response of the direct sound of speakers that are the same
brand and model to verify faults.
On the MR-PRO, select GENERATOR from the main menu, click on WAV and select PNOISE, click
on MOD and select CONT.
Adjust the gain of your system and the MR-PRO until the Pink Noise signal can be heard at a decent
level.
On the XL2, select SLMETER/RTA from the main menu, and select from the second menu.
Choose LZS with Capt and Live . Set resolution to 1/3rd Octave .
Position the microphone so that it mainly picks up the di-
rect sound from the speaker (for example, at one meter). In
two-way systems, the microphone should have the same
distance from the tweeter and woofer. Use the same relative
position for measuring each speaker.
Connect the MR-PRO to a line
input of your system.
Place the XL2 in front of each
speaker.
