3-28 OPERATION ORBAN MODEL 9400 ROCK-MEDIUM+LOWBASS is an open-sounding preset with a lot of bass punch. Its Multiband Release control is set to Slow2 so that the sound is relaxed and not at all busy. At the same time, the preset is competitively loud. It is an excellent choice for “adult contemporary” and “soft rock” formats where long time-spent-listening is desired. SMOOTH JAZZ: This preset is designed for commercial stations playing smooth jazz (Kenny G., etc.). It is a loud preset that is designed to prevent stridency with saxes and other horns. WMA MUSIC: This preset is based on GREGG SLOW but has been edited to minimize artifacts in the Windows Media Audio V9 codec when operated at bitrates below 64 kbps. See Processing for Low Bitrate Codecs and HD Radio on page 3-8. WMA NEWS-TALK: This preset is based on NEWS-TALK but has been edited to minimize artifacts in the Windows Media Audio V9 codec when operated at bitrates below 64 kbps. URBAN: There are two URBAN (Rap) presets: HEAVY and LIGHT. These are similar to ROCK-MEDIUM and ROCK-OPEN but with a different bass sound. They use the 3- pole (18 dB/octave) shape on the bass equalizer. URBAN-HEAVY is appropriate for Urban, Rap, Hip-Hop, Black, R&B, Dance and other similar formats. URBAN-LIGHT is appropriate for light R&B formats. Highly competitive Urban stations might also use LOUD-HOT+BASS or LOUD+SLAM, modified versions of LOUD-HOT that maximize bass punch. Equalizer Controls The table summarizes the equalization controls available for the 9400. Note that there are two separate equalization sections, one for AM analog-channel processing and one for HD AM processing. Differences between these equalization sections are noted in Table 3-3 on page 3-29. “Advanced” controls are accessible only from 9400 PC Remote software. Any equalization that you set will be automatically stored in any User Preset that you create and save. For example, you can use a User Preset to combine an unmodified Factory Programming Preset with your custom equalization. Of course, you can also modify the Factory Preset (with Basic Modify, Full Modify, or Advanced Modify) before you create your User Preset. In general, you should be conservative when equalizing modern, well-recorded program material. This is particularly true with general-purpose AM programming. Bass Shelving Equalizer:, The 9400 processing’s low bass shelving equalizer is designed to add punch and slam to rock and urban music. This equalizer is only provided for the digital radio processing because many analog AM radios do not handle extreme bass boost gracefully, particularly at very low frequencies. Instead, we provide the low frequency parametric equalizer (which provides a bell-shaped boost instead of a shelving boost) to boost bass in the analog AM channel.
OPTIMOD-AM DIGITAL OPERATION 3-29 The shelving equalizer provides control over gain, hinge frequency, and slope (in dB/octave). BASS FREQ sets the frequency where shelving starts to take effect. This would by the +3 dB frequency for infinite BASS GAIN. For lower bass gains, the gain is progressively less than +3 dB at this frequency. BASS GAIN sets the amount of bass boost (dB) at the top of the shelf. BASS SLOPE sets the slope (dB/octave) of the transition between the top and bottom of the shelf. Depending on the preset and adjustment of the band 5 compressor/limiter in the digital processing channel, the 9400’s processing may increase the brightness of program material in the digital processing channel. Hence, bass boost is sometimes desirable to keep the sound well balanced spectrally. Adjustment of bass equalization must be determined by individual taste and by the requirements of your format. Be sure to listen on a wide variety of receivers — it is possible to create severe distor- Equalizer Controls Group Basic / Full Advanced Name Range Modify Name Bass Shelf (HD AM only) BASS FREQ Bass Frequency 80, 85, 90, 95, 100, 105, 110, 115, 120, 125, 130, 135, 140, 145, 150, 160, 170, 180, 190, 200, 210, 220, 230, 240, 250, 270, 290, 310, 330, 350, 380, 410, 440, 470, 500Hz BASS GAIN Bass Gain 0 … 12 dB BASS SLOPE Bass Slope 6,12,18 dB / Oct Low LF FREQ Low Frequency 20 ... 500 Hz LF GAIN Low Gain –10.0 … +10.0 dB LF WIDT Low Width 0.8 ... 4 octaves Mid MID FREQ Mid Frequency 250 ... 6000 Hz MID GAIN Mid Gain –10.0 … +10.0 dB MID WIDTH Mid Width 0.8 ... 4 octaves High HIGH FREQ High Frequency 1.0 … 15.0 kHz HIGH GAIN High Gain –10.0 … +10.0 dB HIGH WIDTH High Width 0.8 ... 4 octaves HF Enhancer HF ENH High Frequency 0 … 15 Enhancer HF Gain HF Gain High Frequency 0 … 22 dB (analog only) Shelf Gain HF Curve (analog HF Curve High Frequency 0 … 10, NRSC only) Shelf Curve Brilliance (HD BRILLIANCE Brilliance 0.0 … +6.0 dB only) DJ Bass DJ BASS DJ Bass Boost Off, 0 … +10 dB System Filters LOW PASS Lowpass 4.5, 5.0, 5.5, 6.0, 6.5, 7.0, 7.5, 8.0, 8.5 ,9.0. 9.5(NRSC) kHz LPF Shape –0.1, –3.0, –6.0 dB HI PASS Highpass 50 ,60, 70, 80, 90, 100 Hz Table 3-3: Equalization Controls
