Connections and wiring
CAT-5 cables used to interconnect remote input plates carry
low-level audio. To minimise noise and interference from
outside sources, only screened CAT-5 should be used. Only
use shielded RJ45 plugs when wiring this part of the system,
bonding the foil screen of the cable to the metal screening
can of the plug.
ME-1 mic input plates should be connected to the RJ45
connectors labelled MICROPHONE INPUTS on the
DCM-1.
LE-1 line input plates and BE-1 balanced line input plates
should be connected to the RJ45 connectors labelled
EXTENSION PORTS on the DCM-1. Do not connect
any music sources to the phono sockets corresponding to
the Extension Ports being used.
The remote plates all have two RJ45 sockets, labelled
OUTPUT and LINK. The “rst” plate in a daisy‑chain
wiring system should be connected to the DCM-1 using its
OUTPUT socket. The LINK socket on this plate should be
connected to the OUTPUT of the next plate in the chain,
and so on until the last plate in the chain.
Note that the single CAT-5 interconnection provides
DC power as well as audio. A full pin allocation of the
microphone inputs and extension ports can be found in the
Appendix at the end of this manual.
The DC power consumption of the active circuitry is quite
low, and no PSU capacity problems should be experienced
in the vast majority of installations. Refer to page 53 for PSU
and current ratings.
