System Components
DCM-1
The DCM-1 is the system “core” and all the primary audio
input sources, zone amplier inputs, paging mics/control and
all remote controls are connected directly to it. The DCM-1
mainframe should ideally be rack-mounted along with the
audio sources and zone ampliers, in a central equipment
area.
A practical multi‑zone audio system is perfectly realisable
with just a single DCM‑1, but system exibility and ease
of operation will be greatly enhanced by the addition of
optional Cloud remote controls and/or local input plates.
Optional components
CDR-1
Zone
The CDR‑1 is a remote control unit specically designed for
use with the DCM‑1. CDR‑1s may be tted to standard
electrical back boxes in whatever location is convenient in
each zone. Any zone may have one CDR‑1, more than one,
or none at all. The DCM-1 can support up to 100 CDR-1s.
CDR-1s are interconnected with just one standard CAT-5
UTP cable; units may be daisy‑chained at will and/or
connected individually back to the DCM-1’s four CDR ports
using almost any wiring topology convenient for the
installation.
The DCM-1’s own PSU has the capacity to power up to
8 CDR-1s directly, via the CAT-5 connections. Systems
requiring more than 8 CDR-1s will need additional power
supplies, whose location and system connection will depend
on the topology and cable lengths involved. Full details are
provided with each CDR-1.
The CDR-1 provides the user with local source selection
and level control for the zone in which it is tted. It
additionally allows selection of any zone groups to which
the zone has been assigned, which gives simple and complete
control over audio in multiple areas which may be split or
joined in different ways at different times.
Once enabled on the DCM-1 and a local key code entered,
zone EQ is also adjustable from the CDR‑1, allowing audio
optimisation from within the zone itself. An Installer Mode
permits zone assignment and adjustment of other installation
parameters.
