This equipment enables up to six zones to be selected from a mi-
crophone base. It is possible to activate/de-activate music for each
zone by means of the front-panel switches provided for this purpose.
It can be used both with line signals (upstream from the amplifier)
and with power signals (output from the 100-V line amplifier). The
P8036
has provisions for connecting two amplifiers (one for music
and one for speech) to it or it can be configured for operation with a
single amplifier for both voice and music. It has 4 inputs for auxiliary
sound sources with a selector switch and level control, an input on a
terminal board for connecting several microphone stations (
B711-G
and/or
B711/6-G
) and a VOX priority input for sound sources such as
a message or alarm-tone generator. The selected music signal, with a
controlled amplitude, will be available on the MUSIC OUT output, while
the voice signal from the base or from the VOX input (depending on
the priority) will be available on the MIX OUT output. If there is only
one amplifier, the music featuring the lowest priority level may also be
available on that input. The unit can be installed directly on a 19” rack,
occupying the height of one modular unit.
FUNCTIONAL FEATURES
• Selection of voice/music on six zones via relay
• Possibility of activating/de-activating music for each zone by
means of front-panel switches
• Four inputs for music sources
• VOX line input with automatic activation of precedence and All Call
• Input for B711 range pre-amplified microphone bases on a screw-
down terminal block
• Separate 100-V inputs for music and speech
• Selection of Base/VOX or VOX/Base priority
• Six zone-line outputs on screw-down terminal block with three-
wire connection for overriding the local volume attenuators
• MUSIC OUT and MIX OUT outputs
• Service relay for special types of activation (pre-recorded
messages, alarm tone, etc.).
• Can be mounted in a 19” rack, height: 1 module
• Power supply: 230 VAC/24 VDC
Microphone bases for announcements and connections

connections
for direct SFTP CAT5 shielded cables
(AUDIO IN / AUDIO OUT). B711/6-G sta-
tions also have ZONE 1 to 6 sockets for
controlling the zone-switching relays.
The connectors must be shielded RJ45
connectors. On the P8136, on the other
hand, there are two removable bayonet-
type terminal blocks for connections:
one for the audio and the precedence
control (‘BASE INPUT’) and the other for
selecting the zones to be called (‘ZONE
SELECT’).
