DSP MODULE - DUCKER
This module allows to attenuate one or more input channels depending on the signal level of the priority
channels.
Its parameters are:
-
REF SOURCE: selection of the input channel(s) that will activate the priority.
-
FADER: gain that is applied to the reference signal when the ducker is activated.
-
MUTE: mutes the reference signal when the ducker is activated.
-
THESSHOLD: threshold value, when the signal of the REF SOURCE channels exceeds this value the
priority will be activated and attenuated according to the selected DEPTH value.
-
DEPTH: attenuation ratio to be applied to non-priority signals when the module is activated.
-
ATTACK: priority reaction time when the signal is above the threshold value.
-
RELEASE: reaction time to stop applying priority when the signal falls below the threshold value.
-
HOLD: time the priority shall remain active after the signal falls below the threshold value.
-
ON/OFF: enables or disables the module. If OFF (disabled) the input signal is not processed and is
passed on to the next processing module.
On the left you can see graphically the combination of the parameters, G.R. which will show the amount of
attenuation applied.
DSP MODULE - ANC - AMBIENT NOISE COMPENSATION
This module automatically adjusts the channel volume to compensate for ambient noise in the room. This
takes place thanks to a sophisticated algorithm that listens to ambient noise through a dedicated microphone.
To better understand its application, we can think of a shopping centre. The ambient noise will not be the
same when it is empty as when it is full, so the warning messages to be emitted must be made louder or
quieter respectively in order to be audible to the users. If we were to set it to the worst-case scenario, when
it is full, the volume of messages would be excessive when there are few users.
