Table 3-3: Multi-Band Equalization Controls
Most equalization controls are common to both the Two-Band and Multi-Band struc-
tures. The equalizer is located between the AGC and multi-band compressor sections of
both structures.
The Protection Limiter structure does not have equalization controls.
Any equalization that you set will be automatically saved in any User Preset that you
create and save. For example, you can use a User Preset to combine an unmodified Fac-
tory Programming Preset with your custom equalization. Of course, you can also modify
the Factory Preset (with
LESS-MORE
or
FULL CONTROL
) before you create your User
Preset.
In general, there is no good reason to have to use large amounts of EQ (or even any EQ
at all) with modern, well-recorded program material. The 6200 multi-band compressor
was “tuned” with reference to modern well-recorded CDs, and should produce a highly
“commercial” spectral balance with no extra EQ at all. Only if you want to create un-
conventional spectral balances for your transmission should you use the equalizers.
Table 3-3 shows a summary of the equalization controls available for the Multi-Band
structure.
LOW BASS boost control, the Multi-Band structure’s low bass equalization control, is
designed to add punch and slam to rock and urban music. It provides a shelving boost in
two ranges with two switchable characteristics. 2P provides a range of 0dB to +12dB (in
