Chapter 4: Using the Chat Application 23

Advanced Settings: Audio Settings

Audio Settings displays the current audio settings and allows you to change them for the CHAT 170 currently con-

nected 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:

USB Audio• : These controls affect the audio settings of the CHAT 170 when it is connected via USB to your com-

puter. Use the Mute buttons to mute either the microphone or speaker on the CHAT 170. 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• : These controls affect the audio settings of the CHAT 170 when it is connected to devices through

its I/O jack, such as handset telephones and video conferencing devices. These functions are unavailable if only

the USB is connected and appear grayed-out. 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 receiver side of the call.

Speaker• : These settings are only available when the VC Breakout Box is connected. The following options are avail-

able:

Normal• : USB audio and line in audio from the VC Breakout Box are mixed through the CHAT 170 speaker.

Video Mode• : 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 170 speaker. Ensure that the CHAT 170 RCA connection ca-

ble (included with the CHAT 170 VC configuration) is properly connected (see the section Connecting CHAT

170 To A Video Conferencing Device in this manual for detailed instructions). USB audio still comes through

the CHAT 170 speaker in this mode.

External Speakers• : With this option selected, all audio (both USB and line in) is muted on the CHAT 170 and

routed to the line out jack on the CHAT 170 VC Breakout Box, to which you can connect external speakers and/

or an amplifier. In this mode, you are using the CHAT 170 as a microphone device only.
