Built on almost 20 years of research and development, ongoing worldwide field testing and award-winning, breakthrough technology, the SIM 3 audio analyzer system is the newest generation of acoustical audio analysis in an integrated hardware and software package. In the field or on the bench, the SIM 3 system analyzes entire sound systems as easily as it verifies the performance of individual electronic components.
Pro Audio Systems owns and operates a complete SIM 3 system. Using this system, we can measure and correctly set-up and align sound systems in venues of all types, allowing users to obtain optimum clarity and coverage.
The technique is a dual-channel acoustical analysis method in which the excitation signal may be independent of – not generated or determined by – the measurement system.
Source independent measurement uses faster, high-resolution algorithms that substantially decrease errors and achieve more precision than conventional dual-FFT techniques. Source independent measurement provides the information required to verify the components of a sound system including polarity, distortion, dynamic range, coverage and more.
The combined components can then be precisely aligned using the SIM 3 audio analyzer's capability to guide the process of setting crossover parameters, delay times, equalization, level and speaker positioning.
In addition, the SIM-3022 audio analyzer’s high-quality 24-bit converters and ability to make measurements with over 110 dB of dynamic range enable THD (total harmonic distortion) measurements down to .001%. For frequency response, the SIM 3 analyzer displays information above 1 kHz (averaged 16 times) in less than one second, while frequencies from 250 Hz to 1 kHz are displayed in less than three.
