CHAPTER 4: USING THE CHAT APPLICATION
OPTIMIzING SOUND QUALITY
for optimal sound quality, you must adjust the CHAt 50’s audio settings for each device and application you will be
using as described in the procedures below.
> Note: the volume settings in the CHAt software are synchronized with the windows volume settings.
Changing the volume using the CHAt software or the buttons on the CHAt 50 also changes the volume
settings in windows. Conversely, changing the volume settings in windows also changes the settings
in the CHAt software.
USING THE CHAT APPLICATION
If not already open, start the CHAt application. 1.
for the CHAt software, click the 2. My Devices button and select the device you want to tune (select the Other or All
option if your device/application is not listed), then click the Apply to CHAT button.
for external hardware devices, connect the device to the CHAt 50 using the connection diagrams found in

Chapter 2 of this manual.
Adjust the speaker and volume settings on the external device or in the application to 50% (half volume).
4.
Click the 5. Advanced button to display the pre-defined audio settings for the device you selected in step 2. Use
the USB Audio section of the screen to tune applications; use the Line Audio section to tune external hardware
devices connected to the CHAt 50’s 3.5mm port.
> Note: In the Advanced screen, adjusting Microphone Level under USB Audio changes the CHAt 50
microphone volume for USb applications, while adjusting the Output Level under Line Audio changes
the microphone volume being sent to the device connected to the CHAt 50’s line audio jack. Likewise,
adjusting Speaker Level under USB Audio changes the CHAt 50 speaker volume, while adjusting
the Input Level under Line Audio changes the speaker volume being received from the connected
device.
Place a call using the device or application. Land lines provide the best audio for tuning purposes. 6.

click and move the Input slider in the CHAt application until the caller’s voice can be clearly heard. Repeat as

additional devices and applications.
to switch between audio settings for different devices and applications, click the My Devices button, select the desired
device or application, then click the Apply to CHAT button. the audio settings are instantly applied for the chosen
device or application.
Using the Application With Pre-Defined Device Settings
the pre-defined device settings available in the CHAt application will provide good sound quality for many of the most
popular devices used with the CHAt 50. If you used the procedure in the previous section to configure the CHAt 50’s
settings for one of these devices, test the sound quality before performing any additional tuning. If you are satisfied with
the sound quality, no further adjustments are necessary.
Using a Third-Party Application
If you are using the CHAT 50 with an application other than CHAT−such as Cisco Communicator or Skype−ClearOne
recommends using the tuning wizard or audio configuration controls in that application to adjust audio settings. If the
application does not have a tuning wizard or audio settings, use the CHAt application to tune audio settings for optimal
sound quality as explained in the next section.
