AL1
Compact Acoustical Analyzer
The Acoustilyzer AL1 shares a common hardware platform with the Minilyzer ML1. It greatly expands the Minstruments family with
a comprehensive set of acoustical measurement functions. The practical blend of electrical and acoustical functions, combined with
computer connectivity through the standard USB interface positions AL1 to be an indispensable tool for every sound/system contractor,
installer and multi-media specialist. For existing Minilyzer users a Crossgrade package is offered.
ACOUSTILYZER
Real Time Analyzer
Reverberation Time RT60
Speech Intelligibility STIPA
Zoom FFT, Delay, THD+N, ...
Class 0 design
Long Battery Life (>16h)
Sound Level Meter
Featuring SPL (act, max, min), LEQ,
repeatable short time LEQ and logging
functionality. RTA display is selectable
without interrupting broad band meas-
urements, fulfi lling any event monitor-
ing requirement.
Real Time Analyzer, RTA
Fast RTA with 1/3 and full octave
resolution also calculates SPL, LEQ and
Max/Min for each band. Numerical cur-
sor readout with peak hold. Fast log-
ging of RTA results together with broad
band values via PC interface.
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 fi lters and
narrow band effects. Features detailed
cursor readout and data storage.
Octave band RT60 measurements
(8 octave bands from 63 Hz to 8 kHz)
according to ISO3382 with auto trigger,
ranging and averaging. Suitable gated
pink noise sequences are included on
the supplied Test-CD.
Calculates the delay time between elec-
trical ref erence signal and signal from
built-in microphone. A designated chirp
is provided on the Test-CD. The auto-
matic difference display simplifi es the
verifi cation of delay line arrangements.
The STIPA analyzer option allows reli-
able measurement of the intelligibility
within 15 sec. according to the latest
IEC standards. Measurements may be
referenced to previously acquired noise
level spectra. TNO verifi ed algorithm.
