Audio input terminals

The selectable audio input terminals on the Previdia/STUDIO module layout are:

MUSIC 1, MUSIC 2 – analog input terminals
AUX 1, AUX 2 – analog input terminal with priority
A PAGERS, B PAGERS – microphone-base line connectors
FFT – connector not actually located on the module, for selecting the emergency telephone line
PTT – connector not actually located on the module, for selecting the “PTT” microphone

When accessing the programming page of the “Audio Sources”, the subsection on the right, reserved for the terminal, varies depending on the type of terminal selected:

description of signal
equalization
volume

For the lines of “A PAGERS” and “B PAGERS”, the activation of a noise reduction filter is also available for the entire line of microphone bases.

Chime

In this section, present for each selectable terminal, it is possible to select the introductory message (“bell”) for the message to be played.

You can also select the number of times the message is to be played.

Trigger

Valid only for “AUX” outputs, this option allows you to indicate whether the output is always active or whether it must be activated according to the following alternative modes, replacing any audio flow in progress:

The “AUX” signal is played on activation of the “PR” input which the “AUX” terminals are equipped with

In this case, the status of the input during stand-by must also be indicated (“NO” or “NC”).
The “AUX” signal is played when the audio level exceeds the level indicated in the field

In both cases, you must select the audio zones to which the audio streams coming from the “AUX” terminals are directed.

Line

This button accesses programming of the lines of “A PAGERS” and “B PAGERS” and of the microphone bases of which they are composed.
