4. Ducking function
:
When input with MIC, the volume of the line audio will be automatically turned down
to the preset volume level, if there is no input MIC audio signal after 5 seconds, then
the volume will be automatically turned up to the original one. If you need to
disable/enable the ducking function, just send the c
ommand “
610%
” again.
5. ID coding
The ID codes of PA3V ranges from 0 to F (hexadecimal), when sending RS232
commands, please take notice of the address of the ID code.
If the address of the ID code is
0
, any RS232 command is available.
If the address is in
1
~
F
, it has one unique ID code (If the ID code is not the same with
the address, no RS232 command will work).
While the ID code is in
1~F
, please add “
ID/
” before sending the command.
For example, if the ID code is
5
, the RS232 command needed is
“
604%
”, the correct
command is in this format:
5/604%
.
There is no need to add “
ID/
” before the command when the ID code is
0
.
Examples:
1)
Switching the input 2 to the line out, the command is:
2A1.
2)
Turning up the volume of line audio, the command is:
603%
3)
Preset the MI
C volume to “21” degree, the command is:
521%
4)
Checking the working status of PA3V, the command is:
600%
5)
If the ID code is
0
, sending command
601%
is able
to
turn up the MIC volume.
If the ID code is
2
, sending command
601%
will not work, and the MIC volume
remains unchanged. The right command is
2/601%
.
