The
FT
DX
5000
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 another independent group of settings when the speech processor is on.
Setup of the Parametric Microphone Equalizer
1. Connect the microphone to the
MIC
jack.
2. Set the [
RF PWR
] knob to its minimum value, to re-
duce interference to other users during adjustment.
A
DVICE
:
We recommend you consider connecting a dummy
load to one of the Antenna jacks, and monitor your
signal on a separate receiver, to prevent interfer-
ence 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 (or blinks) in
the display. To adjust the Parametric Microphone
Equalizer with the speech processor engaged, press the
[
PROC
] button until the “
” and “
” icon
appears in the display.
A
DVICE
:
A blinking “
” icon indicates the Parametric
Microphone Equalizer menu settings have all been set
to “OFF”, as described later.
4. Press the [
MONI
] button, if you want to listen on the
FT
DX
5000
’s internal monitor. Adjust the monitor level
using the [
MONI
] knob.
5. Press the [
MENU
] button briefly. The Menu list will
appear in the display.
6. Rotate the (
VFO-A
)[
SELECT
] knob to find the
“
TAUD
” Menu area, which contains Menu items “
151
”
through “
159
”; these parameters apply to the adjust-
ment of the Parametric Microphone Equalizer when
the speech processor is disabled. Menu items “
160
”
through “
168
” apply to the adjustment of the Paramet-
ric Microphone Equalizer when the speech processor
is engaged.
7. Rotate the (
VFO-B
)[
SELECT
] knob to perform ad-
justments to a particular Menu item.
8. Press the
PTT
switch, and speak into the microphone
while listening to the effects of the changes you are
making (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.
A
DVICE
:
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.

OINT
:
The Parametric Equalizer is a unique system for adjusting the signal quality. Because the high, mid, and low audio 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. Or, the effective “talk power” can be significantly enhanced.
The aspects of configuration that you may adjust with 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.
