GET_LEVEL
Retrieves current level of either an input / output channel or a control group or an audio
matrix node fader.
Generic command syntax is the following:
GET_LEVEL <CONTROLLER TYPE> <PARAMETER 1> <PARAMETER 2><CR>
<CONTROLLER TYPE> can be one of the following values:
M_IN
to retrieve a master device input fader level
S_IN
to retrieve a slave device input fader level
M_OUT
to retrieve a master device output fader level
S_OUT
to retrieve a slave device output fader level
M_CGRP
to retrieve a master device control group fader level
S_CGRP
to retrieve a slave device control group fader level
M_MTX
to retrieve a master device audio matrix node level
S_MTX
to retrieve a slave device audio matrix node level
<PARAMETER 1> is the channel number for all controllers types except for M_MTX
and S_MTX.
It must be in the range: 1 to16 for master/slave input fader levels, 1 to 6 for master/slave
output fader levels, 1 to 16 for master/slave control group fader levels.
Input channels 1 to 8 belong to the master unit, input channels 9 to 16 belong to the
slave unit.
For M_MTX and S_MTX controller types, <PARAMETER 1> is the matrix input
channel and must be in the range 1 to 16 (for both master/slave audio matrices), while
<PARAMETER 2> is the matrix output channel and must be in the range 1 to 6 (for
both master/slave audio matrices).
If command execution succeeds, the device will respond to the above command as
follows:
ACK GET_LEVEL <CONTROLLER TYPE> <PARAMETER 1> <PARAMETER 2>
<LEVEL><CR>
with <LEVEL> field indicating the current level in the range 0 to 255.
Some faders have a range of –90 dB to +10 dB, while the GET_LEVEL command return
value has a range of 0 to 255.
Consequently, the following formula can be used to convert from returned value to dB:
dB Level = –90 + 100 .
Notice that if a fader has a different range than –90 dB to +10 dB, the formula that can
be used to convert from returned value to dB will be the following:
dB Level = Min Level + (Max Level - Min Level) .
where Min Level and Max Level are the fader lower and upper bounds in dB, respectively.
