OPTIMOD OPERATION
3-27
Unlike the Two-Band structure, whose two-band compressor has a continuously variable
release time, the release time of the multi-band compressor is switchable to four settings:
slow , mslow (medium-slow), mfast (medium-fast), and fast . Each setting makes a very
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 single-
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.
The Multi-Band structure does not have a Loudness Controller because its “automatic re-
equalization” function tends to greatly smooth out loudness differences between one
piece of program material and the next. Therefore, television users will find that the
Multi-Band structure usually controls loudness well enough to prevent commercials
from becoming obtrusively loud.
Putting the Multi-Band Structure on the Air
The Multi-Band structure is very flexible, enabling you to fine-tune your on-air sound to
complement your programming. There are 21 Factory Programming Presets whose
names are the same as common radio programming formats. 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, customize your
sound using the information in “Customizing the Settings,” which follows.
Customizing the Settings
Each of these presets can be edited with the
LESS-MORE
control to optimize the trade-
off between loudness and distortion according to the needs of the format. They can be
further edited with
FULL CONTROL to fine-tune them.
The controls in the Multi-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, density, and
audible distortion. The following provides the information you need to adjust the Multi-
Band structure controls to suit your format, taste, and competitive situation.
