5.7  Audio stream control 
Pressing the 
 (Audio control) button on the main control panel brings up a control 
window shown in Figure 19. From here you can control the incoming audio data from the DVS 
and outgoing voice audio to the DVS (G723.1compressed to 5.3 K bit per sec).  
A Red color square at the left top corner of each audio control button means an Enabled state.  
 
Note: 
 DVS MIC IN is designed for an electret-foil microphone only, (not dynamic type). 
Use a microphone equipped with a stereo male jack.

AGC (Automatic Gain Control) – controls the DVS microphone input. When this feature is 
enabled, the MIC sensitivity is changed with the current voice level in the monitoring (i.e. 
hearing) area. This is extremely useful for low audio level amplification. It is strongly 
recommended not to use this feature with the remote unit audio output. Use AEC to cancel the 
echo from the remote speaker to the remote MIC. Since the AGC mode is incompatible with the 
MIC IN volume, the slider shown is disabled in Figure 19. It is also incompatible with AEC 
mode. 
 
AEC 
(Acoustic Echo Cancellation) – works only when both DVS in/out audio channels are 
enabled. Use this feature to avoid echo from the DVS unit’s speaker to the DVS unit’s MIC.
