DCM1 & DCM1e Installation and User Guide v1.0 6
Section 1: Overview
Introduction
The Cloud DCM1 is an analogue audio Multi-Zone Mixer. 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 flexibility of configuration than
would be possible with such units. It provides a wide range
of input and output connectivity possibilities to suit most
practical situations. It also offers simple and flexible remote
control in addition to front-panel operation.
The DCM1 has been designed to provide a simple, reliable
and elegant method of providing audio in a number of
different zones, typically the various areas of shops, bars,
hotels, schools, conference centres, offices, factories and even
private residences. Local (per-zone) remote control of music
source and level can be simply provided in as many of the
zones as necessary. The DCM1 has been designed to allow
easy integration with mic and line external inputs, paging
microphones and fire alarm systems. Once set up, the DCM1
allows zones to be combined (and separated) simply, as space
utilisation of the building demands.
An important aspect of the DCM1’s design is that it is
completely self-contained, and can if wished, be completely
configured and controlled without a computer interface of
any kind. If a computer interface is preferred, the DCM1
Utility Tool software application may be downloaded free of
charge from
www.cloud.co.uk . The DCM1e variant includes
the additional capability of being configured and controlled
from an Internet browser running on any compatible device
via an Ethernet connection.
The DCM1 allows connection of up to eight line-level sources
such as CD players, audio jukeboxes, PC sound cards, radio or
TV tuners, etc. In addition, both Cloud paging microphones
(PM or CDPM Series) and third-party paging systems may
be directly connected. Each of the eight outputs is intended
to supply audio to a separate zone. Two of the zone outputs
are available in stereo. Any one source can be routed to
any zone, and the music level in each zone can be adjusted
independently.
The capabilities of the DCM1 and DCM1e are explained in
greater detail in System Capabilities on page 9.
