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 pas être exposé aux écoulements ou aux éclaboussures et aucun
objet ne contenant de liquide, tel qu’un vase, ne doit être placé sur l’objet.
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.
La prise du secteur ne doit pas être obstruée ou doit être facilement accessible
pendant son utilisation. Pour être complètement déconnecté de l’alimentation
d’entrée, la prise doit être débranchée du secteur.
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.

Safety Considerations and Information
The MA80FT amplier must be earthed. Ensure that the mains power supply
provides an effective earth connection using a three-wire termination.
Caution – High Voltage
Do not touch any part or terminal carrying the hazardous live symbol while power
is applied to the unit. Terminals to which the hazardous live symbol refers require
installation by a qualied person.
Caution - Mains Fuse
The internal PSU contains no user-replaceable fuses. Mains over-current protection
is provided by the fuse in the AC mains plug, which should be rated at 5 A.
Servicing
The unit contains no user serviceable parts. Refer servicing to qualied service
personnel. Do not perform servicing unless you are qualied to do so. Disconnect
the power cable from the unit before removing the top panel and do not make any
internal adjustments with the unit switched on. Only reassemble the unit using
either the original bolts/screws, or ones identical to the original parts.

OVERVIEW
Introduction
The MA80FT is a very compact mono amplier designed for integration into audio
and AV systems where de-centralised installation is advantageous. It is intended
as as an “install-and-forget” component, and is small enough to be tted into wall
or ceiling voids or in any convenient location adjacent to projectors, at screen
displays or loudspeakers. A simple set of controls and conguration options makes
it easy to integrate into any audio system. It is highly suitable for use with instore digital signage, gallery and museum exhibits and xed or mobile tour guide
systems.
The MA80FT can deliver 80 W (mono) into a 4 ohm load, but also includes an
output transformer, enabling it to drive 100 V, 70 V or 25 V-line loudspeaker
systems. It has two unbalanced stereo inputs for line level signals (typically music
sources) and a balanced mic input for paging/announcement use. An alternative
mic input allows the amplier to be fed with paging/announcements from a
100/70/25 V-line loudspeaker system. Front panel controls are provided for line
input levels, microphone level and music EQ. There are also various preset-type
controls and conguration DIP switches on the rear panel, and jumpers mounted
internally on the main PCB. A Cloud LM-2 Series remote input module or RL Series
remote level control can be wired to the amplier’s Facility Port, which can also be
used as an additional line input.
Applicable Models
This Installation and User Guide describes the installation and operation of the
following model:
• Cloud MA80FT 80 W mono amplier for 4 ohm loudspeakers and
100/70/25 V-line loudspeaker systems
NOTE: Amplier models MA80 and MA80E are NOT covered by this Guide, and
when installing either of these models, reference should only be made to the
Guides specic to them.
