The FT-2000 includes 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.

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 experi-
enced before. Effective “talk power” can also be significantly enhanced.
so precisely, it is possible to craft a response that provides a more natural and pleasant sound than you have ever experi-
enced 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.

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.

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.

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.
