Introduction
The Cloud DCM-1 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 exibility of conguration 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 exible remote
control in addition to front-panel operation.
The DCM-1 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, ofces, 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 DCM‑1 has been designed
to allow easy integration with mic and line external inputs,
paging microphones and re alarm systems. Once set up, the
DCM‑1 allows zones to be combined (and separated) simply,
as space utilisation of the building demands.
An important aspect of the DCM-1’s design is that it is
completely self-contained, and requires no computer
interface of any kind, either to congure or control it.
The DCM-1 allows connection of up to 8 line-level sources
such as CD players, audio jukeboxes, PC sound cards, radio
or TV tuners, etc. In addition, both Cloud CDPM Series
paging microphones and third-party paging systems may
be directly connected. Each of the 8 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 exibility of the DCM‑1 is explained in greater detail in
System Capabilities on page 11.
