This menu function sets whether the rear panel Paging
Access Connector (see page 16, Item 7) is to operate as an
input or an output.
The default setting is Input. This congures the Connector
to be used for Zone selection with an 3rd.-party paging
system. The alternative setting, Output, should be used
when the DCM-1 is connected to a Cloud CDPM paging
microphone(s), and per‑zone contact closures are required
for volume restoration. See page 24 for full details of how to
use the Paging Access Connector.
Use the rotary control to change the setting. The numeric
buttons are not used in this function.
CDPM Zone Offset

The purpose of the CDPM Zone Offset menu function is to
permit Cloud CDPM paging microphones to address more
than 8 zones.
The CDPM system can address up to 16 Zones (model-
dependent). To permit paging of Zones 9 and higher in a
system utilising two DCM‑1s, a xed numeric offset of 8
should be set in the “second” DCM-1 (and left at the default
value of 0 in the “rst”). With the rst DCM‑1 feeding audio
to Paging Zones 1 to 8 and the second to Paging Zones 9 to
16, correct paging of the higher-numbered Zones will result.
The rotary control is used to adjust the offset value in the
range 0 (the default) to 15. Values other than 0 or 8 will only
be applicable to hybrid systems composed of a DCM-1 and
mixers of some other type. The numeric buttons are not
used in this function.
CDR Zone Offset
Rotary: sets Offset

DCM-1s may be linked together via the CDR-1 buss to
allow systems with more than 8 zones to be congured. To
maintain the freedom of CDR-1 network wiring, a CDR
Zone Offset is applied to the second (and subsequent)
DCM-1s, in order that the CDR-1s are able to recognise
that the system comprises 16 (or more) zones.
Use the rotary control to set the CDR Zone Offset on the
second (and subsequent) DCM-1s. The offset is in multiples
of 8.
For a 16‑zone system using two DCM‑1s, an offset of +8 is
applied to the “second” DCM-1, whose outputs feed Zones
9 to 16. The “rst” DCM‑1, whose outputs feed Zones 1
to 8 is left with an offset of zero. With the CDR‑1 network
connected to both DCM‑1s, all 16 zones will now be
available to each CDR-1 for assignment.
