Frequency-Domain Graph
Visually the most important element on the main screen, and in fact dominating
the lower half of it, is a large graphical display depicting the standard audio frequency
range of 20Hz – 20kHz arranged in logarithmic fashion with gradations at selected
frequencies. The vertical axis scale changes according to its context.
The FM-531HD Graphical Interface Operation
Select either AGC+SST (pictured below), HD Limiter, or FM Limiter from the
buttons at the top of the Control Area. We’ve worked very hard on the design of the
Wheatstone graphical user interface to make it intuitive, friendly, and easy to navigate
and interpret in spite of the many number of controls the user has access to (well over
350).
Each of the processing section’s screens has a graphical area where not only visual
representations of processing activity are shown, but in some cases individual adjust‑
ments of different sections of the processing can be made.
All of the operating parameters of the five band AGC and the 31‑band HD and FM
limiters can be individually adjusted by manipulating the positions of various “Dots”
on that section’s graphical screen.
Each of the blue dots on the screen represents the center frequency of a band. By
double clicking a blue dot (to highlight it and turn it Orange) and then dragging it with
the mouse, a particular parameter for each band can be adjusted.
