CDR-1 Remote Control Panels
Multiple CDR-1 remote control panels may be connected to
the DCM-1 either by wiring them directly and individually,
or by “daisy-chaining” them together. In most installations,
a combination of these methods is likely to be the most
convenient solution from the point of view of practical
cabling. The diagrams below illustrate the types of wiring
schemes that may be employed; almost any variation on
these is permissible.
Zone outputs
Connect the inputs of the power ampliers feeding the
loudspeakers for each zone to ZONE 1 to 8. Note that
zone outputs 1 and 2 are stereo; if only one set of speakers
are being used in these zones, they may be connected to
either connector.
Standard connection
All 8 outputs provide balanced connection for wiring to
professional/industrial power ampliers with balanced inputs
(typically on XLRs). In this case, wire as the diagram below.
Note that the cables’ screens are not connected at the
source end.
Unbalanced inputs
If audio ampliers with only unbalanced inputs are being
used (e.g. hi‑ ampliers), the following wiring should be
adopted:
Always avoid using pre-made leads of an unnecessary length.
