AUTOMIXER
The automixer function automatically controls and manages the maximum number of
audio inputs (or channels) that are completely open at the same time, reducing the level
of those in excess and compensating the volume of the final mix.
This is useful, for instance, when using multiple microphones in the same room.
Two independent automixers are available: AMIX1 and AMIX 2 .
Important: in the MIXER MATRIX section, it is necessary to assign all matrix
nodes (input / output combinations) to one of the two automixers (see the
respective manual section).
The assignment of each matrix node to one of the two is exclusive.
If the SLAVE unit is present, four automixers will be available: two for the MASTER unit
BUS / audio outputs only, two for the SLAVE unit BUS / audio outputs only.
The selection needs to be made in advance by clicking either MASTER or SLAVE on the far
right of the main window.
Click AUTOMIX SETUP in the main window.
Select the automixer to set by clicking either AMIX1 or AMIX 2 .
MAX NOM: setting of the maximum number of audio inputs (or channels) that
can be fully opened at the same time.
NOM ATTENUATION:
mixed signal attenuation setting.
The attenuation is increased gradually (the set value in decibels) in function of the
doubling of the number of mixed inputs.
For example, if the value is set to –3 dB, with two open inputs the mixed signal will
be reduced by 3 dB, with four open inputs by 6 dB, with eight open inputs by 9 dB,
etc...
SENSITIVITY: setting of the needed audio signal (relative level expressed in
decibels) above the ambient noise level (detected by the same input) needed to
fully open a channel in the mixed signal.
For example, if the value is set to 6 dB, when using a microphone, a channel will
be fully opened as soon as the detected signal is 6 dB above the detected ambient
noise.
OFF GAIN: setting of the attenuation (in decibels) applied to signals of all
channels detected as ‘off’, in which the signal does not reach the needed level (set
by the SENSITIVITY parameter) above the ambient noise.
HOLD TIME:
time expressed in seconds, in which a channel still stays open from
when its detected signal level is below the threshold necessary for full activation.
DEFAULT CHANNEL: setting of a preferential channel that is always kept open.
It is possible to select (only) one of the following three options:
- DISABLED: no default channel, only channels having a signal level above the
activation threshold get opened (and within the maximum allowed number of open
channels).
- STATIC: the default channel is the one selected through the below STATIC CHANNEL
parameter.
- LAST ON: the default channel is the last activated (in chronological order).
