20.3 HOW TO CONFIGURE THE AUDIO CONTROLS FOR PHONE MODES
The microphone connections vary by radio model. On the FLEX-6300, FLEX-6500 and FLEX-6700 a
suitable microphone can be connected to the 8-pin front panel connector. On the FLEX-6400/M and
FLEX-6600/M a microphone can be connected to the rear panel 1/8
th
inch TRS jack. On the FLEX-
6500, FLEX-6600/M and FLEX-6700 a microphone can also be connected to the rear panel balanced
input. See the FLEX-6000 Hardware Reference Manual or the FLEX-6400/6600 Hardware Reference
Manual for more details. In the transmitter control panel, select “MIC” for the 8-pin or 1/8
th
inch
TRS jack input or “BAL” for the balanced microphone input.
See section 31.1.6, DAX TX Channel and Microphone Interaction, for information about coordinating
DAX TX channel usage with microphones.
NOTE: If the DAX button above has been selected and PTT is initiated through CAT, audio will be
used from the DAX source rather than the currently selected microphone input. If, however, a
microphone PTT is depressed, the selected microphone will be used for input. This allows the
operator to switch between a digital audio source and voice audio quickly.
NOTE: When PTT is depressed while the PC is the selected microphone, the PC microphone will not
be used as the source of microphone input. This allows a local microphone to always override a
remote PC. To use the PC microphone, the MOX button must always be used as the PTT control.
20.3.1 Setting the Transmit Filter Bandwidth
The transmit bandwidth of a single sideband is determined by the Low Cut and High Cut bandwidth
controls found on the Transmit Control panel. The bandwidth is adjustable up to 10 KHz in 50 Hz
steps. The transmit bandwidth is double for symmetric sideband modes such as AM.
