InputProfile field is a way of externally controlling the contents of the
mix.
The following example shows a mix.
If the InputProfile of GainType A_XP bunch 0 is externally set to 0 then
the AddToMix source A_G1_P1_L will be added to the OutputMix source
AES_O_P1_L , however, if the value of GainType A_XP bunch 0 is
externally set to 4 then AddToMix source A_G1_P1_R will be included in the
mix.
StartMix "Preview AB1L Mix"
AddToMix A_G1_P1_L A_XP_1 0
AddToMix A_G1_P1_R A_XP_1 4
OutputMix AES_O_P1_L
EndMix
Refer to the Oxtel Automation Protocol manual for automated control of
Bunch Profiles.
MixDown
AddToMix
The MixDown field of the AddToMix command allows sources to be added to
the mix, but at an attenuated level.
Source configurations controlled by input profiles may require more than just
simple re-routing operations. For missing signals that would normally be
present there may often be a need to generate them from a combination of
two or more existing source inputs. In such cases, the sum of the inputs is
likely to give rise to a significantly louder output signal. The
MixDown field
is used to specify an attenuation level that is applied to the input source. The
field specifies a divisor used to attenuate the source signal, e.g. a value of 2
would result in a 50% (~6dB) attenuation.
If the MixDown field is omitted, a value of 1 is used.
