loudness and density. Moreover, OPTIMOD-<strong>AM</strong> actually increases definition and<br />
intelligibility.<br />
If you still wish to use reverb to achieve a nostalgic sound in an oldies format, we<br />
recommend using it in extreme moderation and applying it to the signal before it<br />
reaches OPTIMOD-<strong>AM</strong>. OPTIMOD-<strong>AM</strong> will effectively increase the amount of reverb by<br />
increasing the level of the reverb decay and keeping the reverb before OPTIMOD-<strong>AM</strong><br />
will allow OPTIMOD-<strong>AM</strong> to control peak modulation accurately.<br />
Customizing the <strong>9400</strong>’s Sound<br />
The subjective setup controls on the <strong>9400</strong> give you the flexibility to customize your<br />
station’s sound. Nevertheless, as with any audio processing system, proper adjustment<br />
of these controls consists of balancing the trade-offs between loudness, density,<br />
and audible distortion. The following pages provide the information you need<br />
to adjust the <strong>9400</strong> controls to suit your format, taste, and competitive situation.<br />
When you start with one of our Factory Presets, there are two levels of subjective<br />
adjustment available to you to let you customize the Factory Preset to your requirements:<br />
Basic Modify and Full Modify. A third level, Advanced Modify, is accessible<br />
only from the <strong>9400</strong>’s PC Remote software.<br />
The <strong>9400</strong> is essentially two processors in one. The two processors share the stereo<br />
enhancer and AGC but split independently after the AGC. Other than the stereo enhancer<br />
and AGC controls, all HD <strong>AM</strong> controls are independent of the analog <strong>AM</strong><br />
processing controls. The digital channel processing and analog <strong>AM</strong> processing have<br />
separate and independent LESS-MORE controls. This control independence allows<br />
you to adjust the analog channel to be highly processed (to overcome noise and interference),<br />
while delivering a more conservatively processed, high-fidelity texture<br />
on the HD <strong>AM</strong> channel.<br />
Spend some time listening critically to your on-air sound. Listen to a wide range of<br />
program material typical of your format. Listen on several types of car, table, and<br />
portable radios, not just your studio monitors.<br />
Then, if you wish to customize your sound, read the rest of Section 3 it is important<br />
to understand the functions and interactions of the audio processing controls before<br />
experimenting with them.<br />
See page 6-62 for a block diagram of the processing.<br />
