sets. This is too long to permit live off-air monitoring into talent headphones. This is
the main reason why the 8700i offers 8500-style presets too—these presets have
much lower delays than do their MX counterparts.
Unlike the Two-Band structure, whose two-band compressor has a continuously var-
iable release time, the release time of the Five-Band compressor is switchable to sev-
en increments between slow and fast. Each setting makes a significant difference in
sonic texture.
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 whose names are the same as common programming formats. They offer con-
siderable variety, with various combinations of release time, equalization, low fre-
quency 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-

control can edit each of these presets to optimize the trade-off be-
tween loudness and distortion according to the needs of the format. To fine-tune
them, presets can be further edited with Basic, Intermediate or Advanced Modify.
The controls in the Five-Band structure give you the flexibility to customize your sta-
tion’s sound. Nevertheless, as with any audio processing system, proper adjustment
of these controls requires appropriately balancing the trade-offs between loudness,
density, and audible distortion. The following provides the information you need to
adjust the Five-Band structure controls to suit your format, taste, and competitive
situation.
The Five-Band Structure’s Full Setup Controls
The tables below show the Multiband and Band Mix controls in the dynamics sec-
tion. The AGC, Equalizer, Stereo Enhancer, and Clipper controls are common to both
the Two-Band and Five-Band structures and are discussed in their own sections
above.
Except as noted, these controls affect both the analog and HD processing
chains.
