controls and have adjusted the subjective setup controls in detail to their satisfac-

must fully understand the material in Section 3 of this manual to
achieve the best results from this exercise.
By comparison to competitive processors, the 8600Si offers a uniquely favorable set
of trade-offs between loudness, brightness, distortion, and build-up of program
density. If your radio station does not seem to be competitive with others in your
market, the cause is usually source material (including excess use of lossy digital
compression), overshoot in the transmission link (including the FM exciter) following
the 8600Si, or an inaccurate modulation monitor that is causing you to under-
modulate the carrier. A station may suffer from any combination of these problems,
and they can have a remarkable effect on the overall competitiveness of a station’s
sound.
Section 1 of this manual provides a thorough discussion of system engineering con-
siderations, particularly with regard to minimizing overshoot and noise.
