General Description
The LM-2 Series is a range of remote modules for use with either
the Cloud Z4MK4/Z8MK4 and Z4MK3/Z8MK3 Zone Mixers, or
46-120 and 46-120MEDIA Zone Mixing Amplifiers (see separate
datasheets). An LM-2 module allows a microphone and/or a stereo
music source to be connected physically within a Zone, mixed
together with independent level controls and routed to the Zone’s
amplifier and speakers. Selectable mic-over-music priority is provided.
The LM-2 also provides the same remote control functionality as the
Cloud RSL-6, with selection of background music source and level
control.
combined with that at the phonos. Mic and music inputs are mixed,
with independent control of mic and music level from faceplate
controls. The mixing ability makes the LM-2 particularly useful for
Karaoke.
A faceplate MIC PRIORITY button gives the microphone input
priority (30 dB of ducking) over both the local music source
connected at the LM-2 and the Zone’s background music source
selected at the host unit. If needed, the priority operation can be
changed so that both the mic input and the local music input take
priority (full muting) over the background music.
PLEASE NOTE: The LM-2 module can be used with the
earlier Cloud Z4II and Z8II Zone Mixers, in addition to the 46-50
Integrated Mixer Amplifier. The connection procedure, and details
of how to configure the units to suit, are explained in full in Cloud
Technical Note TN-007, which may be downloaded as a PDF file
from www.cloud.co.uk.
The remote control section of the LM-2 is identical to the Cloud
RSL-6 remote control source and level control. Separate controls
are provided to select the background music source in the
Zone (from the six supported by the host units), and the background
music level.
The LM-2 is available in three different form factors to suit various
international styles of electrical back box. One or more LM-2s may
be installed in a Zone, and are easily wired to the Zone Mixer’s rear
panel Facility Port for that Zone using screened Cat 5 cable and
screened RJ45 plugs.
In many installations, the host unit will normally be located in a rack
along with other audio equipment, and will not be readily accessible.
Installing an LM-2 module in a Zone provides the user with the
ability to plug in a microphone in the Zone itself, and also connect a
wide variety of local stereo line level audio sources such as portable
music systems, CD players, laptops, MP3 players, DJ mixers, radio mic
receivers, etc. The music input is available both as a pair of phono
sockets and as a 3.5 mm stereo jack socket. The L and R stereo
channels are summed to mono, and the signal at the jack input is
Multiple LM-2s may be “daisy-chained” together to provide
additional input/control points in the same Zone; a second RJ45
LINK connector is provided for this purpose. Only one LM-2 in such
a chain may control background music source selection and level;
further jumpers may be set to determine which LM-2 has control.
Standard Cloud RSL-6 or RL-1 remote control plates may be
daisy-chained to LM-2s in the same way; please see the
Technical Notes section at www.cloud.co.uk for full details.
All Cloud products are exclusively designed in the UK.
Every Cloud product is exhaustively tested for electronic performance and sonic perfection in Sheffield, England.

Versions
Six versions of the LM-2 are available; they are electrically identical
and differ only in style and appearance.Versions available are:
The LM-2W and LM-2B mount into a standard dual-gang
UK-style electrical back box (85 x 145 mm).
• LM-2W to fit UK back boxes, white finish
• LM-2B to fit UK back boxes, black finish
• LM-2AW to fit US back boxes, white finish
• LM-2AB to fit US back boxes, black finish
• LM-2DW to fit German DIN-standard back boxes, white finish
• LM-2DBto fit German DIN-standard back boxes, black finish
The LM-2AW and LM-2AB mount into a standard dual-gang US-style
box (114 x 114 mm/4½” x 4½”).
The LM-2DW and LM-2DB have 150 x 80 mm faceplates and are
designed to fit dual gang back boxes (requiring 2 x 68 mm dia.
cutouts) used in several countries, including Germany.
All versions require a back box depth of 35 mm minimum.

Connections
The LM-2 is exceptionally simple to install; the rear OUTPUT
connector is wired to one of the host unit’s Facility Ports with a
single screened Cat 5 cable using standard shielded RJ45 connectors
at each end. The Cat 5 cable carries DC power as well as balanced
audio.
locations in the same Zone. Signals applied to modules wired in this
way will be summed together to the Facility Port to which the “last”
LM-2 in the chain is connected. An internal gating circuit on each
module automatically disables the audio circuitry on any chained
modules which are not in use, to minimise noise contribution.
Each Zone on the host unit has its own Facility Port, and any LM-2s
connected to a particular port will provide inputs to that Zone only,
and source/level control of the background music in that Zone only.
LM-2s are powered from the host unit to which they are connected,
and each takes 12 mA at +15 V and -15 V. In the vast majority of
installations, the host unit will have ample spare power capacity
for several LM-2s. Full details are provided in the host unit’s
documentation.
A second RJ45 connector is provided to permit multiple LM-2s to
be “daisy-chained” together, to provide insert points at different

Architect’s and Engineer’s Specification
An optional remote module shall be available for the Cloud Z4MK4/
Z8MK4 and Z4MK3/Z8MK3 Zone Mixers. It shall also be compatible
with the Cloud 46-120 and 46-120MEDIA Zone Mixing Amplifiers. The
module shall be provided with OUTPUT and LINK RJ45 connectors to
permit connection to the host unit and other similar input modules via
screened Category 5 data cable.
The remote module shall allow the connection of i) a balanced
microphone via a 3-pin XLR connector and ii) a stereo unbalanced
audio source on both phono (RCA) connectors and a 3.5 mm dia.
3-pole jack. All connectors shall be accessible from the front of the
module. The microphone input shall have a gain control with a range
of sufficient magnitude to allow dynamic microphones of any type to
be used effectively. The stereo music input shall have a separate level
control; the phono inputs shall be capable of accepting signals with a
nominal level of 0 dBu, and the jack input signals with a nominal level
of +8 dBu. The stereo channels shall be summed into mono and mixed
with the microphone signal within the module.
A user-switchable priority facility will be provided to reduce the level
of both the music signal connected at the module and the music source
selected at the host unit for that Zone by 30 dB. It shall be possible to
modify the priority operation by internal jumpers so that the sum of
the microphone and music inputs mute the music source selected at the
host unit for that Zone.
www.cloud.co.uk
Issue_1.1
Circuitry shall be included such that interconnected modules which do
not have microphones connected do not contribute any perceptible
noise to the output signal.
The module shall also incorporate remote controls of the rotary type
providing selection of i) music source and ii) music level, within the
host unit. It shall be possible to disable either of these functions on a
module when multiple modules are interconnected, so that only one
linked module in a Zone has control of the host unit.
The remote module shall be available in versions suitable for fitment in
standard UK, US or German electrical back boxes.The modules shall be
available in a choice of finishes.
The remote modules shall be the Cloud LM-2W (UK version, white
finish), the Cloud LM-2B (UK version, black finish), the Cloud LM-2AW
(US version, white finish), the Cloud LM-2AB (US version, black finish),
the Cloud LM-2DW (German version, white finish) and the Cloud
LM-2DB (German version, black finish).
