상세스펙
Speech Intelligibility STI-PA (optional)

The STI-PA function measures the speech intelligibility of public announcement systems according the latest revision of IEC 60268-16:2003 standard. The XL2 displays the measurement results as STI or as CIS results, accompanied by the individual levels and modulation indices of the seven octave bands. The measurement results are acquired from the dedicated STI-PA test signal, generated by the

  • included STI-PA Test CD
  • Minirator MR-PRO, test signal generator, required for audio systems with line inputs
  • NTi Audio TalkBox, acoustic signal generator, required for audio systems with voice microphones, thus measuring the complete signal chain

Analog Audio Analyzer

Together with the balanced XLR and unbalanced RCA inputs includes the XL2 a comprehensive audio analyzer. It measures simultaneously level, distortion (THD+N) and frequency. The internal loudspeaker or headphone output offers audible monitoring of the test signal or just listening to the residual distortion. The optimized low distortion and low noise design enable level measurements down to -112 dBu and residual distortions typically lower than -100 dB, which is unmatched in handheld instruments.


Scope

The scope function visualizes the waveform of the electrical input signal. It automatically triggers to the fundamental frequency and selects the scaling of the X-axis (time) and Y-axis (level) accordingly. The fundamental or most dominant frequency is displayed above the scope screen.
