be an optimum setting for the

punch without triggering look-ahead limiter artifacts.
The Two-Band Structure
The Two-Band structure consists of a stereo enhancer, a slow two-band gated AGC
for gain riding, an equalization section, a gated two-band compressor, and a low-IM
look-ahead limiter. It shares the stereo enhancer, AGC, equalizer, and look-ahead
limiter with the Five-Band structure. The Two-Band and Five-Band compressors are
always active simultaneously. OPTIMOD-PC switches between the structures by send-
ing the output of the desired compressor to the look-ahead limiter’s input. Switch-
ing between the compressors occurs via a smooth cross-fade.
OPTIMOD-PC’s Two-Band Structure can be made phase-linear throughout to maxi-
mize sonic transparency. However, you can also choose an allpass crossover structure
(see
AGC C
ROSSOVER
on page 3-45).
The Two-Band structure has an open, easy-to-listen-to sound that is similar to the
source material if the source material is of good quality. However, if the spectral
balance between the bass and high frequency energy of the program material is in-
correct, the Two-Band structure (when its

control is operated toward
0%) can gently correct it without introducing obvious coloration.
If you need these automatic re-equalization capabilities of the Two-Band
structure, you may find one of the Five-Band presets to be even more ef-
fective.
There are several Two-Band presets. See Table 3-2: Radio-Style Presets on page 3-27.
The P

preset uses the Two-Band structure. In this preset, the stereo en-
hancer, AGC, and equalizer are defeated via their user controls.
Customizing the Settings
Each Two-Band Factory Preset has a
L

-M
ORE
control (located in the Basic Modify
screen) that adjusts loudness.
L

simultaneously adjusts all of the processing
controls to optimize the trade-offs between unwanted side effects as processing
levels are decreased or increased.
If you wish, you may adjust the Modify parameters to your own taste. Always start
with

to get as close to your desired sound as possible. Then edit the Mod-
ify parameters using the Basic, Intermediate or Advanced Modify screen, and save
those edits to a User Preset.
