CHAPTER 7
Using SIM 3
7.12.6. Mic EQ
SIM 3 provides an elegant solution for measuring and correcting the response of a
microphone in its actual environment. The basic procedure is to measure and store the
response of the microphone, and then use the noise generator in conjunction with an
equalizer to match the mic trace.
7.12.7. Console Check
Console Check allows the user to measure various parameters — including THD, polarity,
and frequency response — across a mixing console. In addition, Console Check (Figure
7.47) can measure the throughput latency of the console, which is especially important when
measuring systems that include digital processing.
The branch becomes Generator / Console / Processor, and runs the SIM 3 analyzer’s
generator signal through the console and then to the processor. SIM 3 compares its
own signal with the console and processor output, giving important preliminary system
information before measuring the loudspeakers in the room.
