MPA MK2 Installation and User Guide V1.0 9
OVERVIEW
Introduction
The Cloud MPA MK2 Series are audio mixer-ampliers with
applications in Licensed, Retail, Leisure and similar venues.
Two models are available to suit different output power
requirements (120 or 240 watts); otherwise the models have
identical facilities.
The mixer-ampliers have inputs for six stereo line signals and
two microphone signals. Front panel controls are provided for
music source selection, music level and microphone levels. A
multi-function Facility Port allows the connection of remote
active input modules.
An extensive selection of pre-set controls is located on the
rear panel; primary unit conguration options are selectable
using rear panel DIP switches. Certain installation options are
set using internal PCB jumpers.
The units are also compatible with standard Cloud remote
control plates from the RL and RSL Series.
Applicable Models
This Installation and User Guide describes the installation
and operation of the following models:
Cloud MPA120 MK2: 120 W mono amplier for 4
ohm loudspeakers or 100/70 V-line loudspeaker
systems
Cloud MPA240 MK2: 240 W mono amplier for 4
ohm loudspeakers or 100/70 V-line loudspeaker
systems
All references to “MPA MK2” throughout this Installation and
User Guide may be taken as being applicable to both models.
MPA MK2 Series main features
• Provide amplication and simple control of music, mic
sources and paging in a single unit
• Two versions: output power ratings of 120 or 240 W
• Integral two-channel microphone mixer with per-input
sensitivity adjustment
• Front panel controls for music source, music level and level
of each mic input
• Six (unbalanced) stereo line inputs with individual
sensitivity adjustment
• Two balanced mic inputs – 12 V phantom power available
on either or both
• Fixed 100 Hz hi-pass mic channel lter
• 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 (rear panel) for mic signals
and music source
• Paging control on Mic 1 input via short-to-ground access
connection
• Mic 1 congurable as high-voltage input for paging from
existing 70/100 V-line system
• High-voltage input alternatively selectable to Line 5
input: permits existing background music to be routed via
MPA MK2
• Selectable VOX mic-over-music priority on all mic Inputs
• Automatic Mic 1-over-Mic 2 priority in Page mode; may be
overridden by internal jumper
• Selectable LINE 6 priority with choice of release times
• Selectable pre-announcement chime
• Music Mute control input (N/O and N/C) for interface to
an emergency system
• Facility port 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 Port supports BT-1 Bluetooth input module
• Compatible with standard Cloud remote control plates:
RL-1 Series (music level) and RSL-6 Series (music level and
source selection)
• Power amplier protection circuitry
• Power amplier input limiter
• Transformerless output stage can be congured to drive
either 70/100 V-line systems directly, or low impedance
loudspeakers (4/8 ohms)
• Switchable 65 Hz low-pass lter: reduces transformer
saturation in 70/100 V-line systems
• Aux output from pre-amp (balanced, line level)
• Automatic power-down function (user-selectable)
• ENERGY STAR Certication applied for
• Convection cooled (MPA120 MK2); forced-air cooling with
variable speed control (MPA240 MK2)
• 1U 19” rack mounting unit
Available Options:
• LM-2 remote active mic/line input module with music
source selection and volume controls
