46-50 : 4-Zone Mixing Amplier
General Description
The Cloud 46-50 is a versatile, four-zone, rack-mounting (2U)
audio mixing amplier. It combines simple control of background
music, microphone paging and power amplication for up to
four zones in a single unit. It is suitable for use in many types of
premises, such as pubs, bars, clubs, leisure and tness centres,
shops, ofces, hotels, etc.
The 46-50 has six stereo line inputs and two microphone
inputs; one mic input can be congured for paging purposes.
Each line and mic input has its own preset sensitivity control
on the rear panel, and each mic input additionally has HF/LF EQ
adjustment to optimise the inputs for greatest clarity. The 46-
50 has four mono zone outputs, each being driven by a 50 W
(nominal rating) power amplier stage. Pre-power stage outputs
(0 dBu, unbalanced) are also provided for Zones 1 and 2. Line 6
input may be set to have priority over any other selected music
source in Zone 1, to facilitate connection of a jukebox, digital
sound store or similar device. The priority feature has select-
able release times, to allow a smooth return to the original
music source.
Any or all of the outputs may be congured as high impedance,
allowing the 46-50 to drive 70/100 V-line loudspeaker systems
with the addition of an optional 4-channel, internally-tting
transformer module. Alternatively, single transformers are
available as standard accessories for external connection.
EQ cards to suit popular installation speakers from various
manufacturers may be tted to any or all outputs. If less than
four separate zones are required, the power amplier stages for
Zones 2 and/or 3 may be fed with the programme from Zone
pre-amp sections 1 and/or 4 respectively, doubling the amplier
power available.
The front panel provides separate user controls for adjusting the
level of each mic input, music source selection and music level,
for each zone. Preset controls for HF and LF EQ adjustment of
each zone output are also tted.
The 46-50 is directly compatible with all Cloud PM Series
paging microphones; alternatively, the paging mic input can be
congured to suit most OEM paging systems. Zone selection
for paging is via short-to-ground access connections, and the
unit may be congured by internal jumper for automatic music
ducking (mic-over-music priority), triggered by VOX control.
A particularly useful feature of the 46-50 is the Zone 1 Facility
Port; this allows remote input plates of various types (available
as standard Cloud accessories) to be connected so that mic and/
or line sources - such as radio mics, DJ mixers, iPods, laptops
or other audio sources - may be connected in the zone itself.
This simplies the use of an area of the premises for
presentations or other special functions where portable audio
sources are in use.
Music level only, or music level and source selection may be
controlled remotely in any or all zones if wished, using standard
Cloud RL or RSL Series remote control plates. As with all Cloud
commercial audio products, a remote Music Mute facility is
provided, which may be used to satisfy the requirements of the
Local Fire Ofcer.
