(14) DIP SWITCHES
SHIELD - GND LINK (DIP
switches number 1, 2, 3 & 4)
These 4 DIP switches allow
removing the cable shielding
from the internal ground of the
equipment for each one of the
RJ-45 connectors. Normally they
are in ON position (shielding and
ground joined). To separate the
same, place the corresponding
DIP switch in OFF position.
PRI-PRO LINK (DIP switches
number 5 & 6)
These two DIP switches join
internally the H audio signal and
the C audio signal (when the
input is balanced) that are in the
PRIORITY OUTPUT with the
PROGRAM INPUT. Normally they
are in OFF position (separated
audio signals). To join the same,
place the corresponding DIP
switch in ON position.
PRIORITY CONTROL IN (DIP
switch number 7)
In OFF position, it disables the
priority contact of the RJ45 PRIORITY INPUT
connector in its amplifier, but the RJ45 PRIORITY
OUTPUT is still active.
PRIORITY CONTROL OUT (DIP switch
number 8)
In OFF position, it disables the priority contact of
the RJ45 PRIORITY OUTPUT connector.
PRIORITY CONTACT SURVEILLANCE (DIP
switch number 9)
When in ON, enables the priority contact
surveillance. It is necessary that the activator
follows the figure 12A (if the priority is activated
by means of RJ45 PRIORITY INPUT) or 12B (if
the priority is activated by means of PRIORITY
CTRL terminal block). When the surveillance
detects short-circuit or
open circuit in the priority
control contact the contact
number 2 of the
SURVEILLANCE connector
is activated.
PROGRAM AUDIO BUS (DIP switch num. 10)
In ON position, Links the audio input from one
stage with the audio output from the previous
stage. Allows cascade connection between
different power stages (see figure 9).
PRIORITY AUDIO BUS (DIP switch num. 11)
In ON position, Links the audio input from one
stage with the audio output from the previous
stage. Allows cascade connection between
different power stages (see figure 9).
JPA (DIP switch num. 12)
Set on ON position when the unit includes
OSC-02 oscillator circuits (installations with
DALA-01/0B).
This way, when the power unit protection is
activated, the oscillation is stopped.
