input, the signal will be amplified to ensure the strength of the sound signal output; when the signal strength input
reaches to the certain extent, the signal will be compressed to lower the range of output.
- Input: the level of input automatic gain controller.
- Output: the level of output automatic gain controller.
- Threshold: it is the initial level of automatic gain. When the signal is less than this limit value, the automatic gain
processing module will be enabled to gain the excessively small signal.
- Bypass: the signal input is bypassed and not be processed.
2.3 Scene Control and GPIO
Figure 31
The Scene Control section includes Select scene, Upload, Save and Load. The scene with yellow background is running
scene.
- Save means to save the selected scene configuration to the local (note: it is not the same as the storage of scene in the
“File” menu. As for the latter, the configuration currently in use by the device will be saved to the local).
- Upload: overwrite scene configuration in scene list on the device with the local configuration file. Click“load”,the scene
enabled.
- Load: set the selected scene settings as the currently running scene.
GPIO interface only shows the interface, 16 GPIO indicators shows the current GPIO pin high or low level. GPIO pin level is
high, the display light turns red; GPIO pin level is low, the display lights turn green. Refer to the GPIO setting in the menu
in detail.
2.4Auto Mixer
In the meeting room, 10 microphones, if 10 microphones are open and have the same level, and only one person in the
speech cause the remaining 9 microphones will pick up the room noise, reverberation sound, affect the audio quality.
Secondly, because of these standby microphones, the effective acoustic components of the maximum gain before the
sound feedback would relatively decline and cause volume inadequacy.
Automatic mixer adjust gain from each input channel in real-time to adapt the general level, through improving the high
