Advanced Settings: Audio Settings
The Audio Settings screen (Figure 3.11) displays the current audio settings and allows you to change them
(Figure 3.11). You can also create custom audio settings for a particular device (see the Advanced Screen:
Database section for more information).
Available audio settings include:
• USB Audio: Controls Chat 50 audio settings when it is connected via USB to your computer. Use the mute
buttons to mute the microphone or speaker on the Chat 50. Use the sliders 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.
• Line Audio: Controls line-in and line-out audio levels when the Chat 50 is connected to devices through its
3.5mm jack. These controls are grayed out (unavailable) when there are no devices connected to the
3.5mm jack. 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.
• Speaker: Controls speaker settings when the Chat 50 is connected to devices through its 3.5mm port:
• Normal: USB audio and line-in audio from the 3.5mm jack are mixed through the Chat 50 speaker.
• Video Mode: Routes audio from the far end of the conference call to the connected video
conferencing device or application instead of the Chat 50 speaker. USB audio is routed through the
Chat 50 speaker. Ensure that the Chat 50 is properly connected using the appropriate accessory
adapter cable (sold separately). See figure 2.19 for the connection diagram.
• External Speakers: Routes both USB and line-in audio sources to external speaker(s) connected to
the Chat 50’s 3.5mm jack. In this mode, the Chat 50 functions as a microphone only. This is useful
for video conferencing to ensure the audio and video originate from the same point in the room.
• Line Echo Cancellation: Enables line echo cancellation, which eliminates echo when the Chat 50 is
connected to a telephone. Telephones route audio from the mouthpiece to the earpiece so that you can
hear yourself talk, which causes feedback when using a speaker phone.

Note: Enabling line echo cancellation may cause audio problems if the Chat 50 is not connected to
a telephone
