Advanced Settings: Audio Settings
The Audio Settings screen displays the current audio settings and allows you to change them. 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 con-
nection diagrams earlier in this manual.
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.
WARNING: Enabling line echo cancellation while not connected to a telephone may cause audio
problems, so only use this option while connected to a telephone.
Any settings changes that made on this screen are instantaneously applied to the CHAT 50. In addition, the option
to click on the Save to Database is available to capture the current settings and save them as a custom device as
described in the next section.
