Phoenix Audio Duet Executive MT202-EXE - Manual (Page 6)

HEADSET CONNECTION
CONNECTING EXTERNAL SPEAKERS / HEADPHONES
The Duet is equipped with a 2.5mm standard telephone / cellular phone headset connector.
Connecting a headset to the Duet will automatically disable the Duet’s internal built-in speaker
and microphone. Your PC’s sound (music, VoIP communication, etc...) will be converted into
mono and sent to the headset’s earphone together with the audio signal received by the
telephone. The headset connection is useful when you want to conduct a high quality private
conversation using a standard telephone / cellular phone headset.
The 3.5mm “External Speaker” jack located on the Duet’s connector panel can be used to connect
any type of amplified speakers or stereo headphones. The external speakers / headphones will be
used by the Duet to play sound and the Duet’s internal speaker will be muted.
NOTE: When connecting the Duet Executive to external speakers, the Executive will also send
your telephone’s audio to the external speaker (or headphones). While the internal Executive’s
speaker is disabled when using this connection, the Executive’s internal microphone is still
functional. This feature is useful if, for example, you listen to music stored on your computer
while wearing headphones and the telephone rings. You can pick up the call without taking
the headphones off. It can also be useful if you want to have a private conversation using
standard headphones without the need to purchase a telephone headset.
