Putting the 5-band Structure on the Air

Customizing the Settings

The 5-band structure does not have a separate Loudness Controller because its 5-
band compressor automatically re-equalizes the spectral balance of various pieces of
program material in a way that tends to make their loudness more consistent.
The 5-band structure is very flexible, enabling you to fine-tune your sound for your
target audience and desired market position. There are several basic Factory Presets
for the 5-band structure. Each of these presets can be edited with the L
control. This control affects the sound-for-picture-oriented presets differently than it
does the music presets (presets with "music" in their names). When a sound-for-
picture-oriented preset is on the air, the L

put. This also adjusts the idle gain—the amount of gain reduction in the AGC section
when the structure is gated. (It gates whenever the input level to the structure is be-
low the threshold of gating.)
When a music preset is on the air, the L

tion. In sound for picture, there are no loudness wars; for music presets, there is no
need to advance the L
The controls in the 5-band structure give you the flexibility to customize your station
sound. However, as with any audio processing system, proper adjustment of these
controls requires proper balancing of the trade-offs explained above. The following
provides the information you need to adjust the 5-band structure controls to suit
your programming and taste.
