OPERATION ORBAN MODEL 8600Si
The 8600’s “MX” technology peak limiter consists of two main stages—first, a pre-
limiter stage to control low frequency and high frequency peaks ahead of the main
peak limiter and then the main peak limiter, which uses various proprietary tech-
niques to control distortion, minimize transient loss, and minimize high frequency
loss.
Measurements
The improved performance of the MX peak limiter can be verified by objective
measurements with real-world program material. To measure the improvements in
high frequency power handling capability and dynamic distortion, we use a Stanford
Research Systems SR785 Two-Channel Dynamic Signal Analyzer (Figure 3-10 on page
3-104) to compare the 8500 and 8600. This analyzer has two filterbanks
