QUALIZER
(

MODE
)
The FT-950 includes a unique Three-Band Parametric Microphone Equalizer that provides precise, independent control
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 de-
scribed in the next chapter.

OINT
:
The Parametric Equalizer is a unique technique for adjusting the signal quality. The three audio ranges may be adjusted so
precisely, it is possible to craft an audio response that provides a natural and pleasant sound that you may not have ever
experienced before. Alternately, the Effective “talk power” can 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 output power to minimum value via the
Menu item “
111 TGEN TX PWR 111 TGEN TX PWR
111 TGEN TX PWR 111 TGEN TX PWR
111 TGEN TX PWR
”, so you will not
cause interference to other users while making adjust-
ments.
A
DVICE
:
ˆ We recommend that you connect a dummy load to
one of the Antenna jacks, and monitor your signal
on a separate receiver, to prevent interference to
other users.
ˆ You will have the best chance of hearing the ef-
fects of adjustments if you wear headphones (con-
nected to the monitor receiver) while listening to
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-950 ’s internal monitor.
5. Press the [
MENU
] button momentarily. The Menu list
will appear in the display.
6. Rotate the [ SELECT
] knob to find the “
EQ EQ
EQ EQ EQ
” Menu
area, containing Menu items “
091 091 091 091 091
” through “
099 099 099 099 099
”;
these parameters apply to the adjustment of the Para-
metric Microphone Equalizer when the speech proces-
sor is disabled. Menu items “
100 100 100 100 100
” through “
108 108 108 108 108
” ap-
ply to the adjustment of the Parametric Microphone
Equalizer when the speech processor is engaged.
A
DVICE
:
If you do not find the Menu item number, press the
[
SELECT
] knob momentarily to switch the Menu item
name to the Menu item number.
7. Rotate the [ CLAR/VFO-B
] knob to perform adjust-
ments to a particular Menu item.
8. Close the PTT switch, and speak into the microphone
while listening to the effect of the changes you are
making. Because the overall effect on the sound will
change with each adjustment, you should make sev-
eral passes through each adjustment area, to be sure
that you are achieving the optimum settings.
9. When you have completed all adjustments, press and
hold in the [ MENU
] button for one second to save the
new settings and exit to normal operation. If you only
press the [
MENU
] button momentarily to exit, none of
the changes you performed will 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.
