WARNING:
To reduce the risk of re or electric shock, do not expose this appliance to rain or moisture.
CAUTION:
Use of controls or adjustments or performance of procedures other than those specied may result in hazardous radiation
exposure.
WARNING: SHOCK HAZARD – DO NOT OPEN
AVIS: RISQUE DE CHOC ELECTRIQUE – NE PAS OUVRIR
The lightning ash with the arrowhead symbol within an equilateral
triangle, is intended to alert you to the presence of uninsulated
dangerous voltages within the product’s enclosure that may be of
sufcient magnitude to constitute a risk of electric shock.
The exclamation point within an equilateral triangle is intended to
alert the user to the presence of important operating and maintenance
(servicing) instructions in the literature accompanying the appliance.

IMPORTANT SAFETY INSTRUCTIONS
1. Read these Instructions.
2. Keep these Instructions.
3. Heed all Warnings.
4. Follow all Instructions.
5. Do not use this apparatus near water.
6. Clean only with a dry cloth.
7. Do not block any ventilation openings. Install in accordance with the manufacturers’ instructions.
8. Do not install near any heat sources such as radiators, heat registers, stoves or other apparatus (including ampliers) that
produce heat.
9. Do not defeat the safety purpose of the polarized or grounding - type plug. A polarized plug has two blades with one wider
than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are
provided for your safety. When the provided plug does not t into your outlet, consult an electrician for replacement of
the obsolete outlet.
10. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point
where they exit from the apparatus.
11. Only use attachments/accessories specied by the manufacturer.
12. Use only with the cart, stand, tripod, bracket or table specied by the manufacturer or sold with the apparatus,
when a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.
13. Unplug this apparatus during lightning storms or when unused for long periods of time.
14. Refer all servicing to qualied service personnel. Servicing is required when the apparatus has been damaged in any way,
such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus
has been exposed to rain or moisture, does not operate normally, or has been dropped.
Do not expose the apparatus to dripping or splashing, and ensure that no objects lled with water, such as vases, are
placed on the apparatus.
L’appareil ne doit être exposé aux écoulements ou aux éclaboussures et aucun objet ne contenant de liquide, tel
qu’un vase, ne doit être placé sur l’appareil.
The mains plug is used as the disconnect device and it should remain readily accessible during intended use. In order
to isolate the apparatus from the mains, the mains plug should be completely removed from the mains outlet socket.
Le prise du secteur ne doit pas être obstruée ou doit être facilement accessible pendant son utilisation. Pour être
complètement déconnnecté de l’alimentation d’entrée, la prise doit être débranchée du secteur.
This apparatus is of Class 1 construction and must only be connected to a mains outlet socket with a protective
earthing connection.
Terminals marked with the symbol may use Class 2 Wiring, but voltages at these terminals may be of sufcient
magnitude to constitute a risk of electric shock. The external wiring connected to these terminals requires
installation by an instructed person or the use of pre-made leads or cords.

Optional system components
The following components may form part of the audio system

retrotted to a system at a later time. Separate datasheets
are available for each of the individual components; download
them at www.cloud.co.uk.
Note that full installation and operation instructions are
supplied with each optional component.
CDI-46 digital interface
The CDI-46 card is an optional accessory which gives the
46-120 additional interface and control capabilities. The
CDI-46 is equipped with both Ethernet and RS-232 ports,
allowing the mixing amplier’s primary functions to be
controlled from external systems (Crestron, AMX, etc.) using
either protocol. The card also acts as an Ethernet-to-serial
bridge, converting Ethernet commands to other equipment
into RS-232 data. See page 18 and page page 24 for more
details.
The CDI-46 is also tted with a Cloud Digital Paging interface
(the CDPM/PM INPUT). This provides the simplest method
of connecting Cloud PM Series Paging Microphones, requiring
only a single standard Cat 5 cable. See page 18 for more
details.

MIC INPUT
The LM-2 is an active input module which allows a microphone
and a stereo line input in a remote location to be connected
to the 46-120. The faceplate has both phonos and a 3.5 mm
jack socket for connection of the line input, and provides a
convenient access point for the connection of a DJ mixer,
laptop, MP3 player or similar. Mic and line inputs have separate
level controls. A MIC PRIORITY button activates the Mixer

Amplier’s priority circuitry; when enabled, a microphone
signal, post level control, from the LM-2 will reduce the music
level in the zone where it is installed. Changing a rear jumper
alters the priority operation so that the mixed mic and line
signals from the module cause the mixer’s line input selected
to the Zone to be fully muted.
The module also includes the functions of the RSL-6 Remote
Control Plate (see below), permitting control of zone music
level and source. See page 15 and page 26 for more
information.
The LM-2 connects to the 46-120’s ZONE 1 FACILITY
PORT via screened Cat 5 cable, and the remote sources are
routed to Zone 1. The mixer’s Mic inputs remain available.
Multiple LM-2s in Zone 1 may be daisy-chained to provide
mic inputs in more than one position in the zone. The LM-2
is available in sizes to suit UK, US and German electrical back
boxes; a choice of nishes is also available.
RL-1 Series
The RSL-6 Series is a range of plates allowing local (per-zone)
music source selection as well as music level control. They are
the same size as the RL-1s, and connect in a similar way. See
page 18 and page 26 for more information. RSL-6s are
available in sizes to suit UK, US and German electrical back
boxes; a choice of nishes is also available.

RL-1
The RL-1 Series is a range of small plates with a single control

one of the 46-120’s REMOTE SOURCE + LEVEL ports.
See page 18 and page 26 for more information. RL-1s are
available in sizes to suit UK, US and German electrical back
boxes; a choice of nishes is also available.
RSL-6 Series
Cloud PM Series paging microphones (except the PM1 –
see below) may be connected directly to the 46-120 in
two ways: i) via the CDPM/PM INPUT on the CDI-46
digital interface card (if tted); or ii) using MIC 1 input and
ACCESS CONTACTS port. Models are available which
can page to 4, 8, 12 or 16 zones, and also to 4 or 8 zones with
storage for built-in spot announcements. As the 46-120 only
supports four zones, not all zones on the “higher” models can
be accommodated by a single 46-120; the PM4 and PM4-SA
(4-zone) models are most likely to be useful. See page 16
for more information.
