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 
3. 
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. 
Ask the person on the other end of the call to count from 1 to 10 in a normal voice. while the person is counting, 
7. 
click and move the Input slider in the CHAt application until the caller’s voice can be clearly heard. Repeat as 
needed to find the optimal speaker volume for the device.
while the caller is still on the phone, count from 1 to 10 in a normal voice. Ask the caller if they can hear you clearly. 
8. 
Click and move the Output slider until the caller can hear you clearly. Repeat the test count as needed to find the 
optimal microphone volume for the device.
Click 
9. 
Save to Database to capture the optimized settings. the 
Add Settings to Database dialog appears. Enter 
appropriate name in the Model field, then click the Save to Database button.
the optimal audio settings for the device or application are now ready for use. Repeat steps 1 through 9 for any

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.
