The FT 9000 Contest includes a unique Three-Band Parametric Microphone Equalizer, that provides precise, inde-
DX
pendent 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.

1. Connect the microphone to the front or rear micro-
phone jack.
2. Set the [ RF PWR ] control to its minimum value, so
as not to cause interference to other users during ad-
justment.

Because the setup of the Parametric Equalizer for
both front and rear microphone jacks may take
some time, we recommend you consider connect-
ing a dummy load to one of the Antenna jacks, and
monitor your signal on a separate receiver, so as to
prevent interference to other users.
You will have the best chance of hearing the ef-
fects of adjustments if you wear headphones while
monitoring your transmitted signal.
3. Press the [ MONI ] switch.
4. Press the [ MNU ] key momentarily. The Menu list will
appear on the LCD.
5. Rotate the [ Main Tuning Dial ] to find Menu items
"146" through "163;" these parameters apply to the
adjustment of the Parametric Microphone Equalizer
when the speech processor is disabled. Menu items
"164" through "172" apply to the adjustment of the
Parametric Microphone Equalizer when the speech
processor is engaged.
6. Rotate the [ CLAR/VFO-B ] knob to perform adjust-
ments 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
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 adjust-
ment area, to be sure that you are achieving the opti-
mum setting.

hold in the [ MNU ] key for two seconds to save the
new settings and exit to normal operation. If you only
press the [ MNU ] key momentarily to exit, any changes
you performed will not be stored.

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 Parametric Equalizer adjustments are ap-
plied independently to the front XLR ("Can-
non") and rear (8-pin) microphone jacks, so you
can connect different microphones and custom-
ize the audio response that best suits each mi-
crophone.
The aspects of configuration that you may adjust
on the Parametric Equalizer are:
