3. DSP TX Audio Pass Band
The capable of changing the pass band of your trans-
mit audio, is at your finger tip. Regardless of the con-
dition of the speech compressor, you can adjust by
selecting the [F4 TBW].
You will find this located on the M1 menu. Pushing the
[F4 TBW] for 1 sec. you can step through the TX
audio band pass.
There are three levels of audio passband available
(Wide, Mid, and Nar).
TX Audio Passband widths
Wide : 2.9 kHz ; Great Full Audio
Mid : 2.6 kHz ; Great for operators with
Nar : 2.0 kHz ; Great for breaking through
4. Microphone Equalizer
Although these bandwidths are fixed, the Microphone
Tone Control will give you more audio control for your
Voice operation on SSB, AM, and FM modes. Your
IC-746PRO is equipped with a very powerful equal-
izer system with 121 possible combinations. This is
achieved by using the separate bass and treble ad-
justments. The default for both the Base and Treble
is at 0 dB.
Entering Microphone Tone Control set mode:
q Push [MENU] several time, or until M2 is shown on
the display.
w Push [F4 TCN] for the Tone Control set mode.
e Push the appropriate mode switch to adjust SSB,
AM, or FM.
r Push [F1 ≤] or [F2 ≥] to change to the desired
component.
