Slide 23

Sound Level Meter/RTA Measures real level, L eq , L min , L max , L Cpeak , … Frequency weighting A, C, Z Time Weighting F, S, I* Linear working extent >100dB XL2 precision acc. IEC 61672, class 1 Logs naturally to Mini-SD card Real time clock *optional

Slide 24

Sound Level Meter/RTA Extended Acoustic Pack Percentiles %: 1, 5, 10, 50, 90, 95, 99% Time Weighting: Impulse Sound Pressure Level L Ieq Sound Exposure Level LAE TaktMax as determined in DIN 45645-1 WAV-document recording (ADPCM) Voice note recording High-determination FFT up to 0.3Hz stages

Slide 25

Sound Level Meter/RTA All estimation results are at the same time accessible. Select the accessible levels to be appeared on the XL2 show

Slide 26

Sound Level Meter/RTA 3 or 5 levels might be shown all the while in various selectable sizes

Slide 27

Sound Level Meter/RTA Displays two spectra at the same time Resolution selectable Broadband qualities showed in parallel Measurement go selectable Measurement time and control

Slide 28

Sound Level Meter/RTA Pre-characterized limits for all levels Firmware V1.00 works with altered points of confinement Level alright ��  Limit LED is GREEN Level close cutoff ��  LED is YELLOW Limit surpassed ��  LED is RED

Slide 29

Live Sound Challenges Stage Sound contamination insurance limits most extreme level in gathering of people region. Loudest gathering of people position is ordinarily not open for estimations. XL2 offers a wizard to quantify rectification values k1 and k2 between loudest position and estimation point Loudest accesible position ��  Audience position Measurement Position k1 = Difference in L Aeq k2 = Difference in L CPeak FOH Public listening range

Slide 30

Correction Factor Wizard Run Pink Noise in the amphitheater Measure level at the loudest position Measure level at the estimation point, e.g. at the blending work area FOH XL2 stores comes about with time stamp and shows the ascertained remedy values k1 and k2

Slide 31
