USB/Analog Mix • : Click this box to mix the audio coming into the CHAt 170 through the USb connection with
the audio coming through the I/O jack. for example, if this option is selected and you are talking to a colleague
via Skype on your PC connected to your CHAt 170, and you also initiated a video conference call through the vC
breakout box, all three parties would be joined together for a bridged call. the USb/Analog Mix setting is ignored
while the Speaker option (see above) is set to Video Mode or External Speakers.
Line Echo Cancellation
• : Click this box to enable line echo cancellation. Line echo cancellation eliminates the
echo caused when the CHAt 170 is connected to a telephone. On a telephone, audio is normally routed from the
mouthpiece to the earpiece so that you can hear your own voice while talking, which causes feedback on a speaker
phone.
WARNING: Enabling line echo cancellation while not connected to a telephone may cause audio prob-
lems, so only use this option while connected to a telephone.
Any settings changes that you make on this screen are instantaneously applied to the CHAt 170. In addition, you have
the option to click on Save to database to capture the current settings and save them as a custom device as described
in the next section.
