Cloud 46 Series User Manual

46 Series Installation and User Guide V1.0

OVERVIEW
Introduction
The Cloud 46 Series are four zone audio mixer-ampliers,
with applications in Licensed, Retail, Leisure and similar
venues.
Two models are available to suit different output power
requirements (4 x 120 or 4 x 240 watts). Otherwise the
models have almost identical facilities.
The mixer-ampliers have inputs for six stereo line signals and
two microphone signals. Front panel controls are provided
for music source selection, music level and microphone level
in each of the four zones. Two multi-function Facility Ports
allow the connection of remote active input modules.
An extensive selection of pre-set controls is located on the
rear panel; primary unit conguration options are selectable
using rear panel DIP switches. Certain installation options are
set using internal PCB jumpers.
The units are compatible with standard Cloud RL-1 and
RSL-6 remote control plates, and may also be remotely
control using RS-232 and TCP/IP commands.
Applicable Models
This Installation and User Guide describes the installation
and operation of the following models:
 Cloud 46-120MK2: 4 x 120 W mono mixer-amplier
for 4 or 8 ohm loudspeakers, or 70/100 V-line
loudspeaker systems
 Cloud 46-240: 4 x 240 W mono mixer-amplier
for 4 or 8 ohm loudspeakers, or 70/100 V-line
loudspeaker systems
All references to “46 Series” throughout this Installation and
User Guide may be taken as being applicable to either model.
46 Series main features
• Provides amplication for four zones, with simple per-zone
control of music, mic sources and paging in a single unit
• Available in two versions, with output power ratings of 120
or 240 W per zone
• Transformerless output stages: can be congured to drive
either 70/100 V-line systems directly, or low impedance
loudspeakers (4/8 ohms)
• Model 46-120MK2 permits power sharing in Hi-Z mode:
maximum available power of 240 W may be shared as
required between Zones 1 & 3 and Zones 2 & 4
• Front panel controls for music source, music level and mic
levels in each zone
• Two unbalanced and four balanced stereo line inputs, with
individual gain trim controls
• Two balanced mic inputs; 12 V phantom power available
• Fixed 100 Hz hi-pass mic channel lters
• Separate microphone limiter circuit to prevent power stage
limiter from ducking music signal in the presence of high
mic levels
• Separate HF/LF EQ adjustments for mic signals and music
source
• Paging control of Mic 1 input via short-to-ground access
connection for each zone
• CDPM Digital Paging port, for use with Cloud PM Series
Paging Microphones
• Selectable VOX mic-over-music priority
• Selectable LINE 6 priority
• Music Mute control input (N/O and N/C) for interface to
an emergency system
• Two assignable Facility Ports for connection of LM-2, L-1 or
M-1 remote input modules via screened Cat 5 cable; LM-2
also allows remote control of music level and line input
selection
• Facility Ports support BT-1 Bluetooth input modules
• Compatible with standard Cloud remote control plates:
RL-1 Series (music level) and RSL-6 Series (music level and
source selection)
• RS-232 serial and Ethernet TCP/IP control ports; protocol
includes global and per-zone functions
• Alternative output routing available (Z1 preamp to Z1
and Z3, Z2 preamp to Z2 and Z4): allows higher power
operation over fewer zones
• Power amplier protection circuitry
• Power amplier input limiters
• Switchable 65 Hz high-pass lter (per-zone): reduces
transformer saturation in 70/100 V-line systems
• Balanced Utility output with separate rear panel controls
for music/mic mix: music source can follow Zone 1
selection or be permanently LINE 1
• Two assignable auxiliary outputs from pre-amp (balanced,
line level, pre/post music level routing options)
• Automatic power-down function (user-selectable)
• Thermostatically-controlled forced-air cooling
• 2U 19” rack mounting units
