2.4.7 INPUTS AND OUTPUTS OF AUDIO SOURCES
a ) RECORD OUPUT
The equipment has a line level balanced audio output, which includes a
switching signal active at low level (TTL). It allows monitoring and recording the
messages sent from the emergency microphone. When at one or more voice
evacuation zones, a warning is issued by live voice (microphone), the
recording output will be activated, reproducing the emission signal at the zone
or voice evacuation zones. In that case, the output operation is activated at a
low level.
The connection is made by euroblock female connector and 4-pin 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).

(b) PRIORITY INPUT (PRIO INPUT)
NEO-Extension models have a PRIO Input instead of a REC Output. This priority input
for PA mode, it is activated through a contact closure in pin “M”, when active, the PA led light
will blink. The audio of this input will be routed to every output while the activation signal is
active, unless the system enters into Emergency mode, in that case, the emergency inputs will
have priority and the routing will be assigned according to the evacuation.
(c) PAGING MICROPHONES AND SYSTEM DEVICES INPUT (ACSI BUS)
The NEO 8060 has an special input for microphones where MPS-8Z
and VAP-1 units are connected. It is an input that combines line-level audio,
control signals and power supply for up to 8 devices in bus mode. This line
uses input number 5 of the available audio inputs, therefore when it is been
used, input number 5 will be occupied. For more information about the
connection of this input, see chapter 4.2 .
The connection is made via Ethernet cable, T568B standard.
Maximum connection distance for the entire bus is 1000m (914,4 yrd).

NOTE: This connection is not compatible with the Ethernet standard.
(d) AUDIO LINE LEVEL OUTPUT
The equipment has 8 balanced audio line level outputs, one per amplification channel.
The audio signal will be the same routed at each amplifier.
The connection is made using 8 female connectors euroblock type of 3 contacts and
pitch 3.81 mm (supplied with the unit). The wire size range for each pole of this connector is:
0.14 1.5 mm2 (30 14 AWG).
