Changing The Speaker Output Configuration - Yaesu FTDX-9000D Operation Manual

C
An internal switch, and the menu, allow you to configure the way audio is fed to the two internal speakers (either "stereo"
or "monaural" modes are available).
Advice
At the factory, the audio signals from both the Main and Sub receivers are combined, and the resulting monaural audio takes
advantage of the combined aperture of the two speakers. For most operation, this configuration results in beautiful audio
reproduction, and is to be preferred. If you wish to leave the speaker setup as is, you may skip the remainder of this section.

"A." For listening to audio from the Sub (VFO-B) receiver,
connect an external speaker to rear-panel terminal "B."
With respect to the switch on the Speaker Unit, the left position is SEP and the right position is COM .
Speaker Selection Switch Configuration
1. Set the front panel's Main Power switch to the Off
(" ") position to turn the radio off.
2. Turn the rear panel Power switch off, and unplug the
AC cable from the rear-panel [~AC IN] jack.
3. Remove the eight screws from the left and right faces
of the outer case, then remove the three remaining
screws that are affixing the top case, and remove the
top case from the transceiver.
4. Refer to the illustration, and change the position of
the speaker selection switch (the default setting is
"COM" which combines the audio; "SEP" separates
the Main and Sub receiver audio into the Left and Right
speakers).
5. Replace the three screws on the top case, then replace
the eight screws previously removed from the left and
right sides of the transceiver.
6. Speaker re-configuration is now complete. You may
now plug in the AC cable, and turn the rear panel and
front panel Power switches back on (in that order), to
resume operation.
