Operation Modes (Audio Management) Dual Comm Versions:
The headset is designed to support multiple audio sources through ports located at the bottom
of the in-line control module. The behavior of each port has been designed to support a wide
range of applications. Any combination and presentation of input and output audio signals can
be configured within the electronics of the control module, including but not limited to the follow-
ing scheme.
Port 1 is intended to be the primary communications port and can support binaural or mon-
aural sources. When the source is monaural, the cable for that device is wired such that the
monaural signal is paralleled so that it is made compatible with the binaural connection and the
user will always hear the audio from Port 1 in both ears. Whenever Port 1 is connected, press-
ing PTT 1 shorts the control line to the Port 1 source which enables transmission of the boom
microphone signal to the Port 1 source. If there is no source connected to Port 1, nothing
happens when PTT 1 is pressed.
