the main clipping distortion controller to work harder on speech while preserving
punch in music.

The Five-Band Structure

The Five-Band structure consists of a stereo enhancer, a slow gain-riding two-band
AGC, an equalization section, a five-band compressor, a dynamic single-ended noise
reduction system, an output mixer (for the five bands), and a complex peak limiting
system.
Unlike the Two-Band structure, whose two-band compressor has a continuously vari-
able release time, the release time of the Five-Band compressor is switchable to
seven increments between slow and fast. Each setting makes a significant difference
in the overall flavor and quality of the sound.
When the input is noisy, you can sometimes reduce the noise by activating the sin-
gle-ended noise reduction system. Functionally, the single-ended noise reduction
system combines a broadband downward expander with a program-dependent low-
pass filter. This noise reduction can be valuable in reducing audible hiss, rumble, or
ambient studio noise on-air.

Putting the Five-Band Structure on the Air

The Five-Band structure is very flexible, enabling you to fine-tune your on-air sound
to complement your programming. There are numerous Factory Programming Pre-
sets. They offer considerable variety, with various combinations of release time,
equalization, low frequency coupling, and high frequency coupling.
Start with one of these presets. Spend some time listening critically to your on-air
sound. Listen to a wide range of program material typical of your format, and listen
on several types of radios (not just on your studio monitors). Then, if you wish, cus-
tomize your sound using the information in "Customizing the Settings," which fol-
lows.

Customizing the Settings

The L -M control can edit each of these presets to optimize the trade-off be-
ESS ORE
tween loudness and distortion according to the needs of the format. The presets can
be further edited with Basic, Full Modify, or Advanced Modify to fine-tune them.
The controls in the Five-Band structure give you the flexibility to customize your sta-
tion sound. Nevertheless, as with any audio processing system, proper adjustment of
these controls requires proper balancing of the trade-offs between loudness, den-
sity, and audible distortion. The following provides the information you need to ad-
just the Five-Band structure controls to suit your format, taste, and competitive
situation.
