2 44/50: Installation and Operation Manual
1 Safety Notes
The Cloud 44/50 contains several PCB mounted jumpers which can be set to provide the
desired configuration for a specific application; these adjustments should be performed by
a technically qualified person who fully understands the hazards associated with mains
operated equipment. Do not remove the top panel unless you are qualified to do so.
Remove the power cable from the unit before removing the top panel and do not make
any adjustments with the unit switched on.
The Cloud 44/50 is supplied with a power cable fitted with a moulded plug; if the plug is
cut off the lead for any reason, remember that the discarded plug is a potential hazard
and should be disposed of in a responsible manner.
2 General
The Cloud 44/50 is a versatile, multi-source four zone mono mixer with four 50 watt
power amplifiers. The unit has applications where two microphone and four line level
music signals are required to feed four separate areas in any combination. Optional
accessories extend the flexibility of the unit: A dedicated four zone paging mic with pre-
announcement chime is available, a plug-in remote control PCB provides remote control
of music level and source and for line distribution systems, a four channel 100V/70V line
transformer module is also available.
The front panel controls are reduced to a minimum to reduce confusion; if preferred, the
unit can be positioned in a protected area with just the remote music level and source
controls positioned in the most appropriate location. All pre-set controls are either on the
rear panel or protected by covers.
A remote music mute facility is provided which may be used to satisfy the requirements of
the Local Fire Officer.
