1 Safety Notes
For more detailed information refer to the rear of the manual.
• Do not expose the unit to water or moisture.
• Do not expose the unit to naked flames.
• 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 qualified to do so and fully
understand the hazards associated with mains operated equipment.
• The unit has no user serviceable parts. Refer any servicing to qualified service personnel.
• If the moulded plug is cut off the lead for any reason, the discarded plug is a potential
hazard and should be disposed of in a responsible manner.
2 General Description
The Cloud 46/50 is a versatile, Four Zone 50W x 4 Integrated Mixer Amplifier. It has applications where
up to two microphones and six line level music signals are required to feed four separate areas in any
combination. There are various optional accessories that extend the flexibility of the 46/50:
• A paging mic with pre-announcement chime.
• Optional remote plates that allow remote control of music level and source selection.
• An internally mounted 4 channel 100V/70V line transformer module.
• Active input modules for Zone 1 only, such as the DM-1 or LM-1.
• Internal active equalisation modules for speakers
Along with these accessories the 46/50 has: - microphone priorities, fire alarm mute, auxiliary outputs for
Zones 1 & 2 only and the possibility for Line 6 to have priority over the music signals of Zone 1 only.
The front panel controls are reduced to a minimum to avoid confusion; if preferred, the 46/50 can be
positioned in a protected area with the remote music source and level controls positioned in the most
appropriate location. All pre-set controls are on the rear panel or on the front panel protected by a cover.

3 Schematic Diagram
4 Installation
The Cloud 46/50 occupies two units of a standard 19" equipment rack. Sufficient ventilation should be
provided particularly where it is required to deliver a high output power for long periods of time; the unit
draws cool air through the front panel and exhausts through the rear panel. The 46/50 is 320mm deep
but a depth of 400mm should be allowed to clear connectors.
5 Music Inputs
The 46/50 operates in mono but has six stereo line inputs, which are internally mixed to form a mono
signal. The line inputs are suitable for most music sources such as compact disc players, tape players
and receivers etc. All inputs are unbalanced and use RCA type phono sockets. Input impedance is 47kW.
5.1 Sensitivity & Gain Control
All six line inputs have a pre-set gain control on the rear panel adjacent to the respective input
sockets. The input sensitivity can be varied from -12dBu (195mV) to +8dBu (2.0V). The pre-set
gain controls should be set so that all the input signals operate at the same level within the 46/50
and the music level controls have an optimum range of control.

5.2 Music Control - Local or Remote
The music source and music
level control functions can be
controlled from either the front
panel, or a remote control plate
located up to 100m from the
46/50. There are two remote
control plates available for the
46/50 the RSL-6 and the RL-1.
The RSL-6 should be used
when remote control of music
source and music level is
required whereas the RL-1 can
be used when the application
calls for remote control of the
level only (source selection via
front panel). RSL-6 and RL-1
remote control plates can be
mounted onto a standard British
flush or surface mounted 25mm
deep back box. Two-core cable
with overall screen should be
used to connect the remote
controls to the Cloud 46/50 the
diagrams above show how to
connect the two remote plates.
When using an RL-1 remote level control with the 46/50, the relevant jumpers (see list below)
should be in the 'FR' position to allow front panel control of the music source. Self-adhesive
labels (supplied) can be affixed to the front panel and/or RSL-6 to identify the available input
sources.
The RSL-6A and RL-1A are available for the American market. They operate identically to the
RSL-6 and RL-1 but have been designed to fit a single gang US electrical outlet box. Front panel
dimensions are 4

5.3 Music Equalisation
Each zone has separate treble and bass controls for the music signals only, allowing an installer
to tailor the response of the music signals to suit the acoustics and speakers of each individual
zone. The equalisation controls are concealed behind a removable plate secured to the front
panel with Allen screws; to gain access to the equalisation controls use the supplied Allen key.
Once the plate has been removed the equalisation controls can be seen below the music
controls for each zone; they are clearly marked 'HF' (High Frequency) and 'LF' (Low Frequency).
A flat frequency response can be achieved by positioning the slots on the control shafts in the
horizontal plane; the HF control has a range of ±10dB at 10kHz and the LF control has a range
of ±10dB at 50Hz.
5.4 Line 6 Priority over Zone 1
The Cloud 46/50 has a facility that allows Line 6 a fully automatic priority over the music signal
of Zone 1 only. This is intended for use with input sources such as jukeboxes or spot
announcement players. Should you wish to activate line 6 priority set internal jumper J24 to the
'ON' position. When line 6 priority is activated, Zone 1 functions normally until a signal is detected
at line 6, at which point the selected music source in Zone 1 will mute, allowing the line 6 signal
to be heard. Once the signal on line 6 ceases, the selected music source in Zone 1 will smoothly
restore to its former level. The time taken for this restoration can be 3, 6 or 12 seconds
dependant on how internal jumper J25 has been set; the factory default restoration time is 3
seconds.
When setting the jumper please ensure that you:
• Remove the mains cable from the rear of the product before removing the top
panel.
• Only reassemble the unit using screws identical to the original parts.
