ENHANCING TRANSMIT SIGNAL QUALITY

PARAMETRIC MICROPHONE EQUALIZER (SSB/AM MODES)

The FT-2000includes a unique Three-Band Parametric Microphone Equalizer, that provides precise, independent control over the low-, mid-, and treble-ranges in your voice wave-form. You may utilize one group of settings for when the speech processor is off, and an independent group of settings for when the speech processor is on.

QUICK POINT:

The Parametric Equalizer is a unique technique for adjusting the signal quality. Because the three ranges may be adjusted so precisely, it is possible to craft a response that provides a more natural and pleasant sound than you have ever experienced before. Effective “talk power” can also be significantly enhanced.

The aspects of configuration that you may adjust on the Parametric Equalizer are:

Center Frequency: The center frequency of each of the three bands may be adjusted.

Gain: The amount of enhancement (or suppression) within each band may be adjusted.

Q: The bandwidth over which the equalization is applied may be adjusted.

1.Connect the microphone to the MIC jack.

2.Set the [RF PWR] knob to its minimum value, so as not to cause interference to other users during adjustment.

ADVICE:

￿We recommend you consider connecting a dummy load to one of the Antenna jacks, and monitor your signal on a separate receiver, so as to prevent inter- ference to other users.

￿You will have the best chance of hearing the ef- fects of adjustments if you wear headphones (con- nected to the monitor receiver) while monitoring your transmitted signal.

3.Press the [MONI] button, if you want to listen on the FT-2000’s internal monitor.

4.Press the [MENU] button momentarily. The Menu list will appear in the display.

5.Rotate the Main Tuning Dial knob to find the “EQ” Menu area, containing Menu items “123” through “131;” these parameters apply to the adjustment of the Parametric Microphone Equalizer when the speech processor is disabled. Menu items “132” through “140” apply to the adjustment of the Parametric Microphone Equalizer when the speech processor is engaged.

6.Rotate the [SUB VFO-B] knob to perform adjustments to a particular Menu item.

7.Close the PTT switch, and speak into the microphone while listening to the effects of the changes you are mak- ing (in step 6). Because the overall effect on the sound will change with each adjustment you make, you should make several passes through each adjustment area, to be sure that you are achieving the optimum setting.

8.When you have completed all adjustments, press and hold in the [MENU] button for two seconds to save the new settings and exit to normal operation. If you only press the [MENU] button momentarily to exit, any changes you performed will not be stored.

To roll off excessive bass response in a wide-range studio microphone, try putting a 10 dB null at 100 Hz with a bandwidth of “1” or “2,” do about a 3 dB null centered on 800 Hz with a bandwidth of “3,” and then put an 8 dB peak centered on 2100 Hz with a bandwidth of “1.” These are starting recommendations; each microphone and user’s voice will be different, often requiring different settings.
