      Required Accessories

      The Acoustilyzer is a handheld sound level meter and acoustic analyzer for measuring and monitoring of sound pressure level at concerts, room acoustics and speech intelligibility STI-PA. The practical blend of electrical and acoustical functions, combined with computer connectivity, positions AL1 to be an indispensable tool for every sound/system contractor, installer and multi-media specialist. The sound level meter meets the standards DIN 15905-5 and SLV 2007. The AL1 requires a measurement microphone for acquiring acoustical signals.

      Sound Level Meter
      In addition to the familiar instantaneous and integrated sound pressure level (SPL) measurements, the repeatable LEQ and LCpeak measurements complete the event monitoring requirements.
      The AL1 visualizes the actual audio spectrum (RTA) without interrupting ongoing sound level measurements. All measurement results may be logged to the internal memory for further investigations.

      RTA, Real Time Analyzer
      The enhanced real time spectrum analyzer (RTA) features high speed measurements with selectable 1/1 and 1/3 octave bandwidth. The RTA simultaneously provides real time single band SPL and LEQ measurements complying with the IEC 60804.
      Stored spectra may be averaged or combined by using the available mathematical functions. The “Max-Min” display is particularly helpful for finding dominant room modes and characterization of listening areas.

      Zoom FFT
      Extremely fast, real-time Zoom FFT with resolutions up to 0.7Hz over the entire frequency range. The ideal tool for visualization of comb filters and narrow band effects. Features detailed cursor readout and data storage.

      RT60, Reverberation Time
      Reverberation time is measured in accordance with ISO3382 in octave audio bands (8 bands from 63Hz to 8kHz), including smart trigger- and ranging features. RT60 with 1/3 octave resolution supported by post processing. The test result reliability is displayed with confidence indicators. Suitable gated pink noise sequences are included in the Minirator MR-PRO and on the supplied Test-CD.

      Delay Time
      The propagation delay time measurement for speaker setups is conducted between the electrical input of the AL1 and the built-in microphone. Automatic difference calculation simplifies the verification of correct delay arrangements for larger halls and auditorium. A designated chirp is provided by the Minirator MR-PRO or the supplied Test-CD.

      Electrical Measurement Functions
      Besides the polarity verification for speakers and systems the AL1 includes basic electrical functions like Level RMS and distortion (THD+N) measurement. Unique smart features, like the "Balance indicator" (immediately showing balanced / unbalanced problems of the connected signals), supports fast debugging of audio systems.

      Speech Intelligibility STI-PA (optional)
      The STI-PA analyzer option allows durable and reliable speech intelligibility measurement within 15 seconds. Besides the single value STI or CIS test result, a detailed view of modulation indices and individual band level results is provided. The STI-PA analyzer includes amplitude weighting in accordance with the 2003 IEC 60268-16 standards release.
      A designated STI-PA test signal is provided by the Minirator MR-PRO or the supplied Test-CD. Acquired measurements may be referenced to previously established background noise level spectra's with automatic recalculation of the STI values.

      MiniLINK PC Software
      MiniLINK supports documentation and data acquisition of all measurement functions. The Acoustilyzer stores the test results in the internal memory, thus later the screenshots and measurement data can be transferred to PC for post processing. Additionally the AL1 features direct online logging of all measurement data to PC. MiniLINK acts as AL1 power supply for longterm operations andsupports all PC's with Windows 2000 + SP3, XP, Vista, Win7 (32 & 64 Bit) and pre-installed USB interface
