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
l
ine input
Line input
threshold value
In order to avoid output of 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 pop display fault information.
Does not detect to enable IP circuit detection function;
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 active speaker sampling rate in broadcasting
Broadcast output
volume
IP active speaker total output volume in broadcasting (0~15)
Audio priority
Network priority: network sound source ( broadcast initiate by
server) priority is higher than the local one.
local priority
：
local sound source ( line input sound source ) priority is
higher than the network audio source.
Higher priority tasks can interrupt lower priority tasks.
