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
specied may result in hazardous radiation exposure.

CAUTION

RISK OF ELECTRIC SHOCK

DO NOT OPEN

WARNING: SHOCK HAZARD - DO NOT OPEN

AVIS: RISQUE DE CHOC ÉLECTRIQUE - 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 sufcient 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

manufacturer’s instructions.

8. Do not install near any heat sources such as radiators, heat registers, stoves, or

other apparatus (including ampliers) that produce heat.

MA60 & MA60media Installation and User Guide v1.2

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 specied by the manufacturer.

12. Unplug this apparatus during lightning storms or when unused for long periods

of time.

13. Refer all servicing to qualied 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 liquids, 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’appareil.

The mains plug is used as the disconnect device and it should remain readily

accessible during intended use. In order to electrically 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.

This apparatus is of Class I 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 sufcient 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 Information

Safety notes regarding installation

• Do not expose the unit to water or moisture.

• Do not expose the unit to naked ames.

• Do not block or restrict any air vent.

• Do not operate the unit in ambient temperatures above 35 °C.

• Do not touch any part or terminal carrying the hazardous live symbol ( ) while

power is supplied to the unit.

• Do not perform any internal adjustments unless you are qualied to do so and

fully understand the hazards associated with mains operated equipment.

• The unit has no user serviceable parts. Refer any servicing to qualied service

personnel.

• If the moulded plug is cut off the AC power lead for any reason, the discarded

plug is a potential hazard and should be disposed of in a responsible manner.

MA60 & MA60media Installation and User Guide v1.2

Safety Considerations and Information

The unit must be earthed. Ensure that the mains power supply provides an effective
earth connection using a three-wire termination.

When the mains switch is in the off (‘O’) position the live and neutral conductors of
the mains transformer are disconnected.

CAUTION – High Voltages

Do not touch any part or terminal carrying the hazardous live symbol ( ) while
power is supplied to the unit.

Terminals to which the hazardous live symbol refers require installation by a qualied
person.

CAUTION - Mains Fuses

The MA60 and MA60media mixer-ampliers are tted with a replaceable mains fuse.
This is located on the rear panel below the AC mains input connector. Only replace
the fuse with one of an identical type and rating.

AC VOLTAGE FUSE TYPE FUSE RATING

230 V or 115 V 20 mm x 5 mm, T2A 2 amp

Note that the failure of the mains fuse may indicate an internal fault. If a replacement
fuse fails immediately the power is restored, no further attempt should be made to use
the mixer-amplier, and it should be returned to your Cloud service centre or other
qualied person for repair.

CAUTION – Servicing

The unit contains no user serviceable parts. Refer servicing to qualied service
personnel. Do not perform servicing unless you are qualied 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.

General Description

The Cloud MA60 and MA60media are compact and versatile mixer-ampliers suitable
for use in Licensed Premises, Retail, Leisure and many other venues. The units can
deliver 60 W (mono) into 4 ohm loads; a transformer option is available for driving
100 V, 70 V or 50 V-line loudspeaker systems. The MA60media has an integral digital
media player which replays audio les in various formats from SD cards or USB
memory devices. In all other respects, the two models have identical facilities.
There are inputs for four stereo line signals and a microphone input for paging/
announcement use. Front panel controls are provided for music source selection,
music level and microphone levels; the MA60media has additional controls for the
digital media player section. There are also various controls of the ‘preset’ type on the
rear panel, and further unit conguration jumpers mounted internally on the main
PCB. A remote level control or combined level control/music source selector can be
wired to the unit for installations that require remote control.
