ENHANCING TRANSMIT SIGNAL QUALITY
PARAMETRIC MICROPHONE EQUALIZER
(
SSB/AM/FM MODES
)
The FT-2000D includes a unique Three-Band Parametric Microphone Equalizer that provides precise, independent con-
trol over the low, mid and treble ranges in your voice waveform. You may utilize one group of settings when the speech
processor is off, and an alternate group of settings when the speech processor is on. The speech processor feature is
described in the next chapter.
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 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.
SETUP OF THE PARAMETRIC MICROPHONE EQUALIZER
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. To adjust the Parametric Microphone Equalizer while
the speech processor is disabled, press the
[
PROC
]
button until the “ ” icon appears in the display.
To adjust the Parametric Microphone Equalizer with
the speech processor engaged, press the
[
PROC
]
but-
ton until the “ ” and “ ” icons appear in the
display.
4. Press the
[
MONI
]
button, if you want to listen on the
FT-2000D’s internal monitor.
5. Press the
[
MENU
]
button momentarily. The Menu list
will appear in the display.
6. Rotate the Main Tuning Dial knob to find the “
EQEQ
EQEQ
EQ”
Menu area, containing Menu items “125” through
“133;” these parameters apply to the adjustment of the
Parametric Microphone Equalizer when the speech
processor is disabled. Menu items “134” through “142”
apply to the adjustment of the Parametric Microphone
Equalizer when the speech processor is engaged.
7. Rotate the
[
SUB VFO-B
]
knob to perform adjustments
to a particular Menu item.
8. 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.
9. 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.
ADVICE:
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.
