4.3 Audio parameters
Coding mode
Broadcast coding, PCM means no data be compressed, ADPCM
means packed data (low network data value).
Line input volume The volume of audio line input
Line input
threshold value
In order to avoid circuit and sound source noise, when the line input
audio range is smaller than the value (line input threshold value), it will
turn off the amplifier automatically within 1min. Line input threshold
value is divided into to 3 levels, 20mV, 30mV, 50mV respectively,
20mV audio range is the lowest, 50mV audio range is the highest.
Network loop
detection
threshold value
The speaker will detect the voice according to the level of IP loop
detection threshold value of the device, when there is no sound output,
the server will have pop up display for the fault information.
IP circuit detection function can be disabled;
The sensitivity of the first level detection is the highest, and the
sensitivity of the five stage detection is the lowest.
Broadcasting
sampling rate
IP wall-mounted speaker sampling rate in broadcasting
Broadcast output
volume
IP wall-mounted speaker total output volume in broadcasting
( 0~15,level 6 is 0dB )
Audio priority
It can select local and network priority, the defaults is network priority.
Network priority: IP broadcast>PTT broadcast>ling input
；
local priority
：
line input>IP broadcast>PTT broadcast.
