Page 6: Safety Information
The product conforms to the following European electrical safety standard. BS EN 60065:2002 (+A2:2010) The MA60 and MA60 mixer-amplifiers have been developed and manufactured media with high quality materials and components, which can be recycled and/or re-used. -
Page 7: Safety Considerations And Information
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-amplifier, and it should be returned to your Cloud service centre or other qualified person for repair. -

Page 14: Installation
19” media rack, rackmount kits (available from Cloud) must be fitted. Two types of rackmount kit are available: one for mounting a single unit, the other for mounting two MA60/ MA60 units side-by-side. See below for mounting instructions. -
Page 15: Rackmounting Two Units
Fit one of the rack ears to the left-hand side of one of the MA60s as shown in the diagram below, using four of the screws provided. Repeat Step 1 for the right-hand side of the other MA60 unit. Remove the two raised-head, hex-socket M4 screws at the right-hand side of the front panel of the first unit, and the corresponding two screws on the left-hand side of the front panel of the second unit. -
Page 16: Ventilation
Ventilation MA60 and MA60 mixer-amplifiers are cooled by natural convection, via vents in media the top and bottom panels. Always allow adequate space around the unit(s) to allow a free flow of air. In 19” rack installations we recommend leaving 1U of rack space above and below each unit. - Page 17 Remote Control of Music Source Select and Level The MA60 and MA60 mixer-amplifiers are compatible with standard Cloud media remote control plates types RSL-4/RSL-4A (music source select and level) and RL-1/ RL-1A (level only). Either type of unit may be connected at the rear 3-pin 5 mm-pitch screw terminal connector , using the wiring shown below.

Page 18: Mic Input
By default, the mic input has automatic priority over the music source. It is also compatible with paging microphones with zone selection by contact closure such as the Cloud PM range, including the PM1 single- zone microphone. See “Paging control” on page 19 for more details. - Page 19 (It is recommended that J14 is left attached to one pin of the header in case a different setting is needed in the future.)

OFF. See “PCB layout diagrams” on page 30 for further information regarding the internal jumpers. Paging via a telephone system The mic input on the MA60/MA60 may be reconfigured to accept an audio input media directly from a compatible telephone system. This permits announcements to be made from some (or any) internal telephone extensions in a building. - Page 21 100/70/50 V-line systems An optional transformer kit (CXL-60T) is available for the MA60/MA60 , to media permit the unit to directly drive 100 V, 70 V or 50 V-line loudspeaker systems. The transformer is rated at 50 W output, and is mounted internally. The outputs are available on a 4-pin 5 mm-pitch screw-terminal connector which occupies the hole in the rear panel normally covered by a blanking plate.
- Page 22 10. Connect the speaker system to the line outputs using the mating connector. Note that only two of the pins will be used; one will always be pin 1 (0 V). MA60 & MA60 Installation and User Guide v1.0 media...
- Page 23 Important - Note that the low-impedance output should not be used once the line output transformer is fitted. Once the transformer is fitted, it is strongly recommended that the MA60/ MA60 ’s 65 Hz high pass filter is set ON by moving internal jumper J13. This is media to minimise distortion due to transformer saturation at low frequencies.
- Page 24 J6. Any of the four line inputs, or the alternative Line 2 MP3 input , may be selected as the fixed MOH music source. See “PCB layout diagrams” on page 30 for further information regarding the internal jumpers. MA60 & MA60 Installation and User Guide v1.0 media...

Page 25: Music Mute Input
In some installations (such as licensed premises or retail outlets within a shopping mall), there may be a local authority or fire service requirement to mute the music signals from a fire alarm control panel when an alarm condition arises. The MA60/ MA60 includes a facility to mute the music programme only (i.e., the mic input... -

VBR. Sample rates supported are: 8 kHz, 11.025 kHz, 12 kHz, 16 kHz, 22.05 kHz, 24 kHz, 32 kHz, 44.1 kHz and 48 kHz Both types of audio file may be present on the memory device; the MA60 will media not differentiate between them in any way. -
Page 28: Normal Mode
This makes it very simple to pre-ordain track playing order; if the tracks are given filenames beginning “01”, “02”, etc., they will be always be played in that order in Normal Mode. MA60 & MA60 Installation and User Guide v1.0 media... -

Page 32: General Notes
To avoid any problems associated with differences in mains supply earthing, we recommend that all MA60/MA60 s used in a multi-zone application should be media co-located and connected to a common mains supply. -
Page 33: Emc Considerations
HF disturbance such as high power communication transmitters, radar stations and the like, it is suggested that input signal leads be kept as short as possible. Always use balanced interconnections wherever possible. If the MA60/MA60 mixer-amplifier is mounted in a 19” rack, media do not locate the unit in close proximity to a powerful amplifier of any kind, which may radiate a strong magnetic field from the power transformer. -
