CLOUD DCM1 & DCM1e
DIGITALLY CONTROLLED ZONE MIXERS
General Description
The Cloud DCM1 and DCM1e are analogue multi-zone audio
mixers. A digital control system, using a front-panel LCD display
and a simple, minimal set of controls replace the relatively large
number of switch and rotary controls found on conventional units,
yet provide far greater exibility of conguration than would be
possible with such units. The mixers provide a simple, reliable and
elegant method of providing audio to multiple zones in retail outlets,
bars, hotels, schools, conference centres, ofces, factories and other
types of premises. Once congured, the mixers allow zones to be
combined or separated as space utilisation of the building demands.
The mixers allow connection of eight line level sources, and provide
eight zone outputs, two of which are stereo. Any source can be
routed to any zone, and the music level in each zone can be adjusted
independently. A wide range of conguration options is available to
the installer to optimise the system to the premises and the client’s
requirements, such as restricting source selection in some zones or
dening minimum and maximum volume levels.
A range of optional remote plates is available to permit music
control in any or all zones and external inputs from mic and line
sources. (See separate datasheets for Cloud accessories CDR-1,
LE-1, BE-1, ME-1.) While the DCM1 and DCM1e are also directly
compatible with the Cloud PM range of paging microphones, most
third-party paging systems are easily integrated. In common with all
Cloud installed audio products,a Music Mute input is provided to aid
compliance with local Fire Regulations.
The DCM1 has been designed to be completely self-contained, and
can be fully congured and controlled without a computer of any
kind. However, a software Conguration Tool is available (a free
download) to enable conguration from a computer if this method
is preferred.
The DCM1e greatly extends the DCM1’s functionality by adding an
Ethernet interface and an internal web server, allowing control from
a smartphone, laptop, tablet device or computer via a web browser.

Key Features
System Example - Hotel/Large Restaurant (DCM1)
The system shown could typically be a hotel or large
restaurant, and illustrate how some of the DCM1’s
many features may be used in practice:
• The large area has two CDR-1 remote controls
in the same zone; typically, these might be adjacent to
doors at opposite ends of the room.
• Two of the areas are separated by a folding partition
which may be removed to create one large space. By
assigning these two zones to a Group within the DCM1,
the two zones can be treated as one for audio purposes
when the partition is removed and return to two
separate zones when it is reinstated.
• Each half of the partitioned area also has an ME-1
mic input plate. Because these have been wired back to
the DCM 1 independently, each can be made available
to their respective room halves as and when required.
Alternatively, it may be that they are only required
when the partition is folded back; in this case they are
activated for the Group instead.
• If the model of mixer is a DCM1e, system control is
available to the user via a web browser on an Internet-
capable device. Browser control can be congured
at installation so that only the operational features
required by the venue staff are accessible to them; all
other functions are password-protected.

Architect’s and Engineer’s Specication
The Zone Mixer’s audio signal paths shall be fully analogue in design;
there shall be a simple menu/display system on the front panel for
accessing all system controls and conguration options. It shall be
possible to access all control functions without the use of any external
computers or software. A PC-compatible software application shall
be available; this shall interface with the Zone Mixer via an RS232
connection and shall provide an alternative method of accessing all
control and conguration options.
Two versions of the Zone Mixer shall be available;these shall be identical
in terms of their audio functions. One shall include an standard RJ45
Ethernet interface and internal web server; on this version it shall be
possible to access main control functions from a standard web browser
on devices connected to the same network as the Zone Mixer.
The Zone Mixer shall have 8 stereo line channels, 4 microphone inputs
and a paging mic input. Line inputs shall be on RCA jacks; one shall also
be available as a balanced input on Euroblock connectors; four shall
also have RJ45 sockets providing balanced inputs for the connection
of optional balanced or unbalanced stereo external connection
modules.The microphone inputs shall be balanced on RJ45 sockets for
connection of optional external modules. The Line Inputs shall each
have level trim adjustment available via the menu system.The remote
modules shall be available in a range of sizes and nishes.
The Zone outputs shall be balanced on Euroblock connectors. At
least two shall be stereo, the remainder mono. It shall be possible to
adjust the following parameters for each Zone output: Level, Maximum
and Minimum Levels; EQ (3-bands). It shall be possible to route any
microphone or line input to any Zone output without restriction,
and to adjust each Zone output level independently. It also shall be
possible to make one or more line Inputs unavailable to any Zone
without restriction. It shall also be possible to dene up to 4 Groups
of Zones; enabling/disabling Groups shall be possible without entering
a password. It shall be possible to assign alphanumeric names to all
Inputs, Zones and Groups;these will still apply after any hardware reset
operation.
An optional remote control plate with the same display as the host
unit shall be available for the Zone Mixer.The plate shall be provided
with IN and OUT sockets to permit series interconnection of up
to 100 plates. It shall be possible to congure a plate to provide the
following control functions for its assigned Zone: for immediate access
- Line Input Select and Music Level; with password entry – Zone EQ
(3 bands). The plates shall be available in a range of styles and nishes.
The Zone Mixer shall interface directly with Cloud PM Series paging
microphones and/or third-party paging microphones employing short-
to-ground zone access.The input for a third-party Paging Mic shall be
dedicated, and on a Euroblock connector; routing this to any/all Zones
will be by contact closure at a separate Euroblock connector. Both
Paging Mic inputs shall have rear panel gain controls; HF and LF EQ
controls shall also be provided, effective on both inputs.
The Zone Mixer shall have a rear panel paging level adjustment for
each Zone. The music signal in a Zone shall reduce in volume when
that Zone is being paged, and the Hold Time, Release Time and Music
Attenuation shall all be adjustable. It shall also be possible to trigger
music level reduction by Zone Selection or Paging Mic signal presence.
It shall be possible to assign per-Zone Priority status to any line or
microphone input, such that a Priority signal above a xed threshold
overrides the current Input selection in each Zone for as long as the
Priority signal remains above the threshold. In connection with this,
the following parameters shall be adjustable: Hold Time, Release Time;
Music Attenuation (Mic Priority only).
There shall be a Music Mute Input; this will cause muting of the music
in all Zones. Muting control shall be congurable on either external
contact closure (N/O) or short-circuit removal (N/C). It shall also be
possible to assign any one line or microphone Input to remain unmuted
during Music Mute operation for Emergency system interface.
The front panel shall provide the following features: power switch,
backlit LCD display,rotary encoder with “press” function and software-
assignable push-buttons for control functions. One of the buttons
shall control the Zone Mixer’s menu system. Five further buttons
shall select submenus, and another button shall activate a set of menu
options which require the entry of a password.The password shall be
redenable by the User. The front panel shall also include various LEDs
indicating: external paging access, remote line input selection, remote
mic input selection and emergency Music Mute activity.
It shall be possible to save all current settings and reload these settings
when power is applied. Alternative power-up options shall be to load
the original factory settings or those in force at power-down, even if
they were not specically saved.
The Zone Mixer shall include an RS232 serial port permitting remote
control of all unit functions and settings.The Ethernet-enabled version
of the Zone Mixer shall also have the ability to relay serial data from
the Ethernet port to the serial port; it shall also be possible to redene
the function of the Paging Access connector to provide open-collector
pull-down outputs becoming active under commands received at the
RS232 or Ethernet ports.
It shall be possible to retro-t optional loudspeaker equaliser cards
to any or all Zone outputs. Cards shall be available to optimise the
outputs for use with various popular installation loudspeakers.
The Zoner shall be built in a steel chassis for mounting in a standard
19” rack enclosure.
The Zone Mixer shall be the Cloud DCM1; the Ethernet-enabled
version shall be the Cloud DCM1e. The remote control plates shall
be the Cloud CDR-1 Series; the remote input plates the Cloud LE-1
Series (unbalanced line), Cloud BE-1 Series (balanced line) and Cloud
ME-1 Series (microphone).
