AAuuddiioo SSeettttiinnggss
displays the current audio settings and allows you to change them for the CHAT 160 currently
connected to your PC). You can also create custom audio settings for a device (see
Advanced Settings:
Database
later in this chapter for more information).
The audio settings are as follows:
•• UUSSBB AAuuddiioo
: These controls affect the audio settings of the CHAT 160 when it is connected via USB to your
computer. Use the
MMuuttee
buttons to mute either the microphone or speaker on the CHAT 160. Use the slid-
ers to adjust the microphone level and speaker level. Speaker and microphone level adjustments made in
the CHAT software will automatically change the speaker and microphone volume levels in Windows.
•
LLiinnee AAuuddiioo
: These controls affect the audio settings of the CHAT 160 when it is connected to devices
through its I/O jack, such as handset telephones and video conferencing devices; they are grayed out and
unavailable if only USB is connected. Use the input slider to adjust the level of the incoming audio to the
speaker; use the output slider to adjust the level of the outgoing audio to the far end.
•
SSppeeaakkeerr
: These settings are only available when the VC Breakout Box is connected. The following options
are available:
•
NNoorrmmaall
: USB audio and line in audio from the VC Breakout Box are mixed through the CHAT 160
speaker.
•
VViiddeeoo MMooddee
: Select this option to allow the audio from the far end of the video conference call to
come through the TV speakers instead of the CHAT 160 speaker. Ensure that the CHAT 150 RCA con-
nection cable (included with the CHAT 150 VC configuration) is properly connected (see CONNECT-
ING CHAT 160 TO A VIDEO CONFERENCING DEVICE for detailed instructions). USB audio still
comes through the CHAT 160 speaker in this mode.
•
EExxtteerrnnaall SSppeeaakkeerrss
: With this option selected, all audio (both USB and line in) is muted on the CHAT
160 and routed to the line out jack on the CHAT 150 VC Breakout Box, to which you can connect
external speakers and/or an amplifier. In this mode, you are using the CHAT 160 as a microphone
device only.
