PM Series Paging Microphones
PM4, PM8, PM12 & PM16
General Description
The Cloud PM range of Digital Paging Microphones is a development
of the successful CDPM Series. The microphones are designed
for general purpose multi-zone applications and have a powerful
range of options that make them suitable for almost any situation.
They are easy to install and configure, and provide the user with an
elegant and simple-to-use unit. The microphones are suitable for
use as free-standing units, or may be wall-mounted for security
and/or space considerations.
PM paging microphones allow for paging to individual, multiple or all
zones; zone groups may also be defined for single-button selection of
several zones. A Press To Talk button enables the integral gooseneck
microphone. A pre-announcement chime may be enabled if required;
an internal chime sounder is provided for local confirmation.
A further configuration option allows for paged zones to be
cancelled after an announcement, or remain selected.

• Multiple-zone paging microphone
•High quality dynamic mic mounted on 300 mm
gooseneck – windshield included. (Alternative 140 mm
gooseneck also available)
PM microphones can be integrated into audio systems in two ways –
via the Cloud Digital Paging Interface, enabling simple connection to
recent Cloud products via CAT-5 cable – or via an analogue interface
to any Cloud (or third-party) audio system equipped with industrystandard short-to-ground access connectors.
• Individual and multiple zone selection
The Digital Paging Interface may be used to interconnect up to 32 PM
Series microphones, to permit paging from more than one location,
with a total allowable cable run of up to 1 km. Different models of PM
may be intermixed on a single network. Overall network connection
to the audio system may be via either interface method. Connection
to recent Cloud products - such as the DCM1 – will be via the Digital
Paging Interface. PM microphones are also directly compatible with
the earlier Cloud CDPM range. PM and CDPM microphones may be
freely intermixed on the Digital Paging Interface.
• LED confirmation of all zone selections
Because PM microphones are also equipped with an “analogue”
short-to-ground access port, they may be interfaced with equal ease
to other current Cloud products, such as the Z4II and Z8II Venue
Mixers, the CX163 and CX263 Mixers and the 36/50 and 46/50
Integrated Mixer Amplifiers. Other, older Cloud products may also
be compatible; please contact Cloud’s Technical Department for
advice or visit the Cloud website (www.cloud.co.uk).
The PM Series provide a configurable two-layer priority system to
resolve the possibility of conflicting announcements when more
than one paging microphone is installed on a network. In addition,
a Busy LED illuminates if an announcement is made from anywhere
in the system. Further configuration options include the ability to
disable selection of one or more zones from individual microphones,
and a “zone offset” facility whereby a microphone with fewer zone
buttons (i.e., a PM4) can address higher-numbered zones.
NOTE: PM Series microphones are also available with an integral
digital message store capable of holding multiple pre-recorded
messages. Please see separate datasheet on the Cloud PM-SA Series
Paging Microphones for further information.

Four models of the PM are available: the PM4, PM8, PM12 and PM16.
The models differ only in the number of zone select buttons on
the front panel (4, 8, 12 or 16 respectively), and consequently in the
maximum of zones that can be supported.

CAT-5
Up to 32 PM Series microphones may be interconnected in a simple “daisy-chain” manner via the Digital Paging Interface, using standard CAT-5
cable and RJ45 connectors. Microphones may be located anywhere in the system, provided that the total cable length does not exceed 1 km.
The “last” microphone on the network may be connected to the host device (zoner, mixer, mixer-amplifier, etc.) in two ways, depending
on its type. The upper diagram shows a host device equipped with the Digital Paging Interface; in this case, the connection may be made with
another ordinary CAT-5 cable.
The lower diagram shows connection to the host being made via the analogue interface, comprising the audio signal from the microphone itself,
and zone selection commands made by short-to-ground contacts. By using the PM’s simple analogue connection, a single unit can interface with
almost any host equipped for paging from Cloud or other manufacturer. Up to 31 further microphones can then expand the network using
CAT-5 cable.

Architect’s and Engineer’s Specification
The paging microphone shall be capable of paging up to 16 zones
either individually, in user-definable groups, or all zones simultaneously.
The microphone shall be available in versions with 4, 8, 12 or 16 zone
paging buttons. It shall be possible to interconnect up to 32 similar
paging microphones with full operational transparency, via standard
CAT-5 cabling.
The microphone shall become active when a non-latching ‘TALK’
button is pressed. Zone selection shall be by electronically latching
buttons, with selection confirmed by LEDs. A non-latching ‘CALL ALL’
button shall also be provided, selecting paging to all supported zones.
Four ‘GROUP’ buttons shall also be provided, and it will be possible
for the user to define a group of zones for each. A ‘CLEAR’ button
will be provided to cancel incorrect zone selections. There shall be
a legend area adjacent to each button for user’s zone identification.
The microphone itself shall be mounted on a gooseneck and
be non-removable. Two lengths of gooseneck shall be available.
The microphone level shall be adjustable by an internal control
of the preset type.
The paging microphone will interface directly to compatible mixers
or other host devices via a digital interface carrying audio, zone
selection and power on a single CAT-5 cable. It will also be equipped
with an analogue interface consisting of an audio output and a
separate short-to-ground control port, permitting its use with any
other host devices equipped with this type of access. The analogue
zone selection interface shall be able to sense when any paralleled
system is active.
Issue_2.0
The microphone will be capable of being powered via either type of
interface, or from a local external PSU. The unit will operate from
both DC (12-24 V) and AC (9-17 V) supplies.
It shall be possible to set various configuration options which
will not be resettable by the user and which will be reinstated
after a power interruption: i) setting zone selection to either
remain in place post-announcement, or to self-cancel; ii) offsetting
zone numbering, allowing a microphone to address a different
(consecutively-numbered) set of zones; iii) locking group definitions
so they cannot be altered by the operator; iv) assigning two levels of
priority, whereby ‘high’ priority will take precedence when messages
conflict when multiple microphones are in use; v) enabling one of
four pre-set internally-generated pre-announcement chimes to be
selected and setting the chime level; vi) disabling the selection of one
or more zones.
The paging microphone shall be built in a compact housing
with a non-slip base for desktop use; the unit shall also be
suitable for wallmounting.
The paging microphone shall be the Cloud PM Series; Model PM4
(4 zones), PM8 (8 zones), PM12 (12 zones) or PM16 (16 zones).
