Rig It, Measure It, Align It!
The SIM 3 system’s unique ability to calculate and display all three transfer functions at the same time makes access to important data easy. By using any two of three measurement points, you can analyze a single component or a complete sound system. In addition, up to four memory traces can be displayed, enabling a quick comparison of measurements.
Multiple overlayed memory traces allow for comparison and crossover adjustments.
In addition to the frequency and phase response measurements SIM 3 allows you to do other amplitude and time-related meaningful measurements.
Band and Line Spectrum: Amplitude vs. Frequency
The high resolution Band Spectrum displays console, processor and mic frequency spectra on a single screen.
Optimized for sine wave stimulus, SIM 3’s Line Spectrum measurement can be used for distortion analysis down to .001% THD. SIM 3's high-quality preamps allow it to measure the noise floor of system components. Signal verification is instantaneous, overall frequency content of the signal being used is obvious, and distortion components are summed and displayed as a percentage relative to the amplitude at the cursor position. This makes amplitude vs. frequency and harmonic distortion analysis quick and simple.
In Spectrum view, using a sine wave as test signal, you can see the fundamental plus harmonics, while calculating THD.
Delay Finder: Time vs. Energy
The Delay Finder function has many uses:
In addition, Delay Finder identifies the latency delay in digital signal processors and internally synchronizes signals in time to enable accurate calculation of transfer functions between points in the system with time differences. Delay Finder will even show you polarity information to help locate miswired loudspeakers and electronic components that are reversed in polarity from the rest of the system.
Understanding the acoustical environment and determining optimal loudspeaker placement has never been easier. The Set System Delay procedure gives you the information to set delay times for proper synchronization of all loudspeakers in a system.
