DCM1 & DCM1e Installation and User Guide V1.018

If transformers are not available, a balanced source may feed

an unbalanced input directly as long as care is taken over how

the connections are made. A variety of design techniques are

in use to implement balanced outputs in audio equipment,

and some designs require different wiring protocols to others.

Installers are advised to check the manuals with each item

for guidance on how the outputs should be connected to an

unbalanced input.

However, the wiring methods shown below will work in a

large number of cases. If hum or other distortion is found to

result, try disconnecting the ‘cold’ leg of the balanced output

(pin 3 on XLRs).

Balanced outputs (XLRs):

Always avoid using pre-made leads of an unnecessary length.

An alternative method of providing additional balanced

sources is to use BE-1 remote input modules connected

to EXTENSION PORTS 1 to 4; these could be installed

adjacent to the DCM1 in such a situation.

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 eight 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.
