  20. XL2 Key Features

  21. Features • Flexible User Interface • Visual Limit LED of high sound levels • Mini-SD Card, 2 GB removable • Real Time Clock • Built-in Speaker • Rechargeable Li-Po Battery included • Automated Sensor Detection reads electronic data sheet of M4260 and M2210 • Wave File Recording* • Voice Notes* *optional

  22. Sound Level Meter / RTA • Applications • Live Sound Events • Environmental Noise Monitoring

  23. Sound Level Meter / RTA • Measures actual level, Leq, Lmin, Lmax, LCpeak, … • Frequency weightingA, C, Z • Time Weighting F, S, I* • Linearoperating range >100dB • XL2 accuracy acc. IEC 61672, class 1 • Logs automatically to Mini-SD card • Real time clock *optional

  24. Sound Level Meter / RTA Extended Acoustic Pack • Percentiles %: 1, 5, 10, 50, 90, 95, 99% • Time Weighting: Impulse • Sound Pressure Level LIeq • Sound Exposure Level LAE • TaktMax as specified in DIN 45645-1 • WAV-file recording (ADPCM) • Voice note recording • High-resolution FFT up to 0.3Hz steps

  25. Sound Level Meter / RTA • All measurement results are simultaneously available. • Select the available levels to be shown on the XL2 display

  26. Sound Level Meter / RTA • 3 or 5 levels may be displayed simultaneously in different selectable sizes

  27. Sound Level Meter / RTA • Displays two spectra simultaneously • Resolution selectable • Broadband values displayed in parallel • Measurement range selectable • Measurement time and control

  28. Sound Level Meter / RTA • Pre-defined limits for all levels • Firmware V1.00 operates with fixed limits • Level ok  Limit LED is GREEN • Level near limit  LED is YELLOW • Limit exceeded  LED is RED

  29. Live Sound Challenges Stage • Sound pollution protection limits maximum level in audience area. • Loudest audience position is commonly not accessible for measurements. • XL2 offers a wizard to measure correction values k1 and k2 between loudest position and measurement point Loudest accesible position  Audience position Measurement Position k1 = Difference in LAeq k2 = Difference in LCPeak FOH Public listeningarea

  30. Correction Factor Wizard • Run Pink Noise in the auditorium • Measure level at the loudest position • Measure level at the measurement point, e.g. at the mixing desk FOH • XL2 stores results with time stamp and displays the calculated correction values k1 and k2

  31. Audio Analyzer • Balanced XLR, unbalanced RCA input • -112 dBu to 30 dBu (1.4uV to 25V) • Residual THD+N <-100dB (0.001%) • Frequency range: 9 Hz to 20 kHz • Frequency accuracy: 0.003% • Loudspeaker and headset output for signal monitoring

  32. FFT Analyzer • Measures LZF and Leq simultaneously • Real time FFT in 3 ranges • 10 Hz - 220 Hzwith 1.5 Hz steps • 20 Hz - 1.7 kHzwith 15 Hz steps • 200 Hz - 20 kHzwith 150 Hz steps • High-resolution FFT including zoom mode up to 0.3 Hz stepswith Extended Acoustic Pack

  33. RT60 Analyzer • Measures 8 octave bands from 63 Hz – 8 kHz according to ISO3382 by Schroeder-method • Auto triggering • Auto averaging • Measurement error indication • Stimulus: • Gated pink noise • Impulse sound source

  34. Polarity Testing • Checks polarity of speaker cabinets, individual drivers and line signals • Positive/Negative detection • Using internal microphone or input signal of XLR/RCA connector

  35. Polarity Testing • In-depth verification of the polarity - frequency relation for speaker cabinets or other multi-way-systems • Sample Screenshot left:The major part of the signal energy is measured in the mid-range frequency bands, thus the overall displayed polarity is NEGATIVE.

  36. Propagation Delay • For accurate setup of delay line arrangements • Measures delay between electrical reference and acoustical signal • Relative measurements supported • Displays distance to speaker in meter or feet

  37. STI-PA Analyzer • Measures speech intelligibility of public announcement systems • Complies with IEC 60268-16 (2003) and NFPA 72 • Displays STI and CIS results • Shows table of modulation indices and Leq’s • Supports ambient noise post processing *optional

  38. Application Profiles • XL2 supports application profiles • Application profile may disable and hide any selections or measurement functions • Allows fixed operator interfaces for basic users • Firmware V1.0 offers a set of fixed application profiles

  39. Store and Log Results • Results stored as ASCII files • Storing all or subsets of measurements results • Adding a voice note to measurement* • Records the ADPCM compressed audio signal in parallel* *optional

  40. Automated Sensor Detection • Automatically detects microphone type • Reads sensitivity • Reads product data • Shows last calibration • ASD CableExtension cable tandem up to 20 m supported

  41. Powering Concept • Rechargeable Li-Po battery • included • typical battery lifetime > 5 hours • Dry cell batteries • type AA, 4 x 1.5 V • typical battery lifetime > 4 hours • Mains power supply 9 VDC • charges Li-Po battery in operation
