Audio quality
Audio quality is controlled from two screens:
• Audio, the quality slider tab
• Advanced Audio
Audio quality slider tab
You can control audio quality using the slider tab to reduce audio delay and
increase audio clarity. This slider controls the number of audio buffers the
PDA uses to smooth out incoming audio streams.
If you experience audio delay, you can decrease the number of buffers and
reduce the delay by using the slider on the Audio screen.
If you experience broken or choppy speech at either end of the call, or the dial
tone sounds choppy, the PDA's volume control may be the cause. To prevent
this problem, use the volume controls on the MVC 2050 toolbar to adjust
volume while using the MVC 2050.
If you experience reduced audio clarity in the receive audio stream, try
increasing this setting. Increasing the Audio clarity setting increases the
number of audio buffers used to process incoming audio. If the delay is too
large, you can decrease this setting.
Automatic Gain Control and feedback
Since MVC 2050 requires a headset to operate properly, disable the
Automatic Gain Control.
Note: When the PDA is used in handsfree mode, without a headset, the
PDA microphone picks up sounds from the speaker, creating a feedback
loop. Automatic Gain Control is used in this instance to avoid
feedback.
