System Example
The example shows how the 46-50’s various features may be used in
an installation situation based on three distinct building areas.
• Six stereo music sources are connected to the line inputs.
Note that the jukebox is connected to Line 6; if this input
priority option is enabled, any jukebox selection will automatically be
replayed through Zone 1, overriding the local selection for the
duration of the track(s).
• Zone 1 has been depicted as using 70/100 V-line loudspeakers,
hence the optional external transformers. In this case, these would
be Cloud type CXL-40T, typically mounted on a CXL-800 rack
tray. Alternatively, one of the transformers on the internally-tted
CXL-4160 module could be used.
• Zone 2 might need additional amplication, so as well as some
of the loudspeakers being driven directly by Zone 2’s output
(using series/parallel wiring to ensure that the total load
impedance remains above 4 ohms), Zone 2’s Aux output is used
to drive a separate external power amplier, which in turn drives
further loudspeakers.
• The example assumes that the Zone 3/Zone 4 ‘slave mode’ is
enabled; this means that Zone 4’s control section will drive
the power amplier stages for both Zone 3 and Zone 4. All the
loudspeakers are physically in Zone 3.
• A paging microphone may be connected to Mic 1 input; the
46-50’s access port allows paging to any or all of the zones by simple
contact-closure.
• Mic 2 input is wired to an XLR socket (suitable decorative plates are
available as standard Cloud accessories) to allow the connection of
an additional microphone which can be routed to any or all zones.
• The system also shows a Cloud RL-1 remote control plate installed
in Zone 3 to allow local volume control, and an RSL-6 in Zone 1 to
allow local source selection as well as volume control. Note that the
RL-1 in Zone 3 is actually connected to the remote control port of
Zone 4; this is because the Zone 3/Zone 4 slave mode uses Zone’s 4
preamplier channel to derive the audio feed.
• A DM-1 remote input plate is shown in Zone 1; this would be
wired back to the 46-50’s Zone 1 Facility Port. It would allow two
microphones to be plugged in within the zone itself, and routed to
the loudspeakers in the zone. The level of each mic is adjustable on
the DM-1 plate itself.
