Appendix C – Single Microphone Operation
Overview
Starting with software modification 11 (SWID 11), the C-5000 has the ability to control both radios with a
single microphone/headset. This feature, hereafter called single-mic mode, is useful for installations
where audio panel space is limited, or it is otherwise impractical to dedicate two ports to the C-5000.
The main features of single-mic mode are as follows:
Audio from all enabled sources are routed to the primary headset.
The operator can dynamically select which transceiver will be used for transmit.
Supports both Mode 1 and Mode 2 operation.
Configuring Single-Mic Mode
You can configure the C-5000’s microphone mode using either the Cobham Remote Programmer
software or from the C-5000’s front panel. To set the option using the Remote Programmer software,
simply select Single or Dual from the Mic Mode combo box, located on the Hardware Configuration
screen. To set the option from the C-5000’s front panel, simply select SINGLE or DUAL from the option
list on the MIC MODE configuration page. This page, depicted below, is located under the SETUP MISC.
sub-menu of the CFG SYSTEM menu.

The Home Page
The main visible difference in single-mic mode is the addition of the active RT indicator, displayed as an
unfilled triangle. The active RT indicator shows which RT will be used for transmit. The illustration below
depicts the HOME PAGE for a system comprised of two digital RT-5000 radios. Both radios are
configured to operate in Mode 2. The Main transceiver of radio 1 is the both the active transceiver for
radio 1 and the active RT for the entire system. The digital transceiver (Guard) is the active transceiver
on radio 2.
