7. arefully First let s catch on the pink noise which is defined as random noise that has been weighted with frequency to produce constant noise power per octave while one octave is added the noise power is attenuated by 3dB Because the ear of human being reflects the logarithm effect to the sound so the pink noise is heard as the same level for each octave Just because of this character the pink noise is always used in the sound reinforcement system to adjust the equalizer Next let s introduce how to use the RSA27 in system Usually it is difficult to grasp the change of frequency spectrum in stage monitor In order to detect the response problems in time A LTO RSA 27 provides easy and useful operation interface which contains 27 bands LEDs display that are used to read the program materials real time The RSA 27 is used to visually judge the character of pink noise signal received by the measurement facilities you may adjust the EQ to optimize the response of a sound system based on RSA 27 LEDs display If there are feedback occurs on some frequency band in system via observing the LEDs display you can kill it through adjusting the level in system in time Generally speaking the frequency response of system is very flat so you will look the LEDs display of RSA 27 like at the same level If some frequency band is out of the level through the RSA 27 display you can adjust the EQ to get the best result In any case the RSA 27 Realti
