8.2. Glossary
• ANC (Ambient Noise Control) function (AN-001T only)
The ANC function automatically adjusts the amplifier's output volume in response to the change in ambient
noise level.
The output volume changes as the ambient noise level goes above or below the set reference level.
• Ducker function
The Ducker function automatically attenuates input signals with lower priority when two or more audio
signals are simultaneously received. This function cannot be used if any of such received inputs is not set for
the Ducker function.
• VOX (Voice Operated Exchange) function (D-001T only)
This function initiates the set paging when an audio signal is input. No paging is initiated when no input
signal exists. If the audio signal drops below a preset level after the VOX function begins operation (i.e. after
an audio signal is fed into the module), the set paging is terminated after approximately 5 seconds.
• NOM (Number of Open Microphones) attenuation function
The NOM attenuation function automatically adjusts an output gain depending on the number of open
microphones.
The output gain is attenuated by the value set on the Utility setting screen (
p. 56-C3 ) each time the number
of open microphones doubles. This function helps to prevent feedback.
• Gate function
The gate function allows the input signal to be passed, attenuated or cut depending on its signal level.
The gate allows the signal to pass when open with the signal level over the set value, and to be attenuated
or cut when closed with the signal level below the set value.
The gate's open/close operations control the Ducker function and the NOM attenuation function.
• Scene
A "Scene" is the unit that defines broadcast pattern and up to 32 types of Scenes can be saved as Scene
memory.
Input and output parameters that have been set can be saved in the Scene memory.
