Main Power Switch
This is the power supply’s main ON (
I
)/OFF (
O
) switch.
If this Main Power Switch is not set to the “ON (
I
)”
position, the FT
DX
9000MP ’s [ POWER
] switch will
not function.
Speaker
Two large-aperture (4”/100 mm) high-fidelity speak-
ers are provided, one each on the left and right faces
of the speaker enclosure.
The left speaker puts out audio from the Main (VFO-
A) receiver, while the right speaker puts out audio from
the Sub (VFO-B) receiver, and the two speakers oper-
ate independently.
MUTE A and MUTE B Switches
Pressing the [ MUTE
(
A
)] switch will mute the audio
from the Main (VFO-A) receiver; similarly, pressing
the [
MUTE
(
B
)] switch will mute the audio from the
Sub (VFO-B) receiver.
The Mute capability is particularly useful during Dual
Receive operation, when you may wish to concentrate
on one signal or the other temporarily without the dis-
traction from the audio from the alternate receiver.
OUTPUT Switch
If you press the [ OUTPUT
] switch (when the [A+B]
switch has already been pushed), the two speakers
become combined, producing an effective doubling
of the speaker aperture (to 8” or 200 mm). This yields
a significant enhancement of overall tonal quality.
Press the [
OUTPUT
] switch once more to restore
separate operation of the speakers, whereby the left
speaker puts out audio from the Main (VFO-A) re-
ceiver, while the right speaker puts out audio from the
Sub (VFO-B) receiver.
Front Legs
The left and right case legs, in the front, may be ex-
tended so as to match the height of the (raised)
FT
DX
9000MP . See page 5 for details.
Headphone Jacks
The “A/A+B” Headphone Jack supplies audio from
the Main (VFO-A) receiver.
The “B/A+B” Headphone Jack supplies audio from
the Sub (VFO-B) receiver.
If the [
OUTPUT
] switch has been pressed, both head-
phone jacks will provide mixed audio from the two
receivers.
FILTER Switch
The left [ FILTER
(
A
)] switch engages the audio filter
for the Main (VFO-A) receiver. The right [ FILTER
(
B
)]
switch engages the audio filter for the Sub (VFO-B)
receiver.
The audio filters feature three high-cut (2.4 kHz, 1 kHz,
and 700 Hz) and two low-cut (500 Hz and 300 Hz)
settings each. To disable the audio filters, please set the
respective switch to its “NORM” selection.
