2.4.3 Speaker Line Device Interface
a) Attenuator Override Input
The equipment has 8 outputs for overriding attenuators in the PA line.
At rest state they have 0V voltage. At active state, each output, has a
voltage of 24V dc (*) and 40mA of maximum electrical current. Each
output has 2 poles.
The connection is via two 8-pin female euroblock connector of 3.81
mm pitch (supplied with the unit). The wire size range for each pole of
this connector is: 0.14
→
1.5 mm2 (30
→
14 AWG).

NOTE: The average consumption of the attenuator override signal is 10mA per unit.
(*): The output voltage could vary between 20 and 27V depending on the state of the battery.
b) End of Line Inputs
The equipment has 8 dual inputs for connecting end-of-line
devices. Each input has 3 terminals, one common and two
terminals for lines A and B, associated with the same
amplifier channel (CH-x). When the activation signal occurs
at one of the inputs, a loudspeaker line failure will be
detected.
The connection is via 8-pin female euroblock connector with
3 contact of 3.81 mm pitch (supplied with the unit). The wire
size range for each pole of this connector is: 0.14
→
1.5
mm2 (30
