Alto-6channels
Multi-function Acoustic Measuring System
Alto-6ch is a 24 bits- 6 Inputs & 2 outputs measurement systems that include a powerful TI 6424
DSP to take in charge critical computations when required.
Alto-6ch ensures real time processing while display and storage are taken in charge by a PC.
Various software measurements modules of the OPUS
TM
suite are available to take advantage of
the Alto-6ch hardware: SLM-4ch module, 6-ch DataLogger module, Building Acoustic module,
Building Vibration (DIN 4150), Human Vibration module (ISO 2631) etc.
Compact, low consumption, flexible, the Alto-6ch provide professional measurements conform to
usual acoustic and vibration standard as 60561/60804/61672, ISO 2631, DIN 4150, ANSI 1.43
