(When Paging is set to ON)
(A14) Priority setting
P R I O R I T Y 3
Set the priority levels for paging broadcasts.
Priority can be set to one of 3 levels, and Priority 1 is the highest.
When the same priority level is set for two or more input channels, paging calls are made according to the
FIFO, LIFO (default), or MIX setting, which can only be set using the supplied PC software.
(When Paging is set to ON)
(A15) Ducker depth setting (when the AN-001T is not used)
D U C K E R - D E P T H O F F
(A16) Paging group setting
P A G I N G 0 1 I N 1 -> O U T 1
Sets the paging group, in which the paging broadcast routing from an input to output(s) is determined.
Note
Changing the parameter in this item during paging broadcast interrupts all paging calls being made through
any channel.
Note: For the compression characteristics diagram, refer to p. 137 .

• DEPTH = 5 (Speech leveler)
Makes paging calls easier to hear by equalizing the difference in speech signal volume that may result from
individual differences in speaker voice volumes or variations in speaker-to-microphone distances.
This level 5 is more effective than level 4. Since the volume is extensively corrected, the feedback margin
narrows, making it liable to occurrences of feedback. Therefore, special care must be taken when installing
microphones and speakers.
This level is suited to microphone speech applications.
1, 2, 3 (default) Setting Range
Set how much the input signal for this channel should be attenuated when there is a paging input with higher
priority than that of the currently selected input channel.
The minus figures in dB represent amount to attenuate input signals. The larger the minus figures, the larger
the amount of attenuation. Selecting "OFF" sets the attenuation to infinity, while selecting "0" sets to no
attenuation, permitting all input signals to be mixed and output.
OFF (default), –50, –40, –30, –20, –10, 0 dB Setting Range
Paging group No.: 1 - 32
Input channel:
1 - 8
Output channel: 1 - 8 (two or more channels settable)
