Note that the cable’s screen should be connected to
terminal 3 at the DM-1 end, and to the shell of the Dsub
connector at the mixer end.
Before the LM-1’s music source and level controls will
operate, the LOCAL/REMOTE push-button switch (
14
on
page 9 -
Rear Panel Description
) to REMOTE (i.e., pressing
it in). In this setting, the zone’s front panel Music Level and
Source Select controls become inoperative.
Paging System connections
Cloud PM Series paging microphones may be connected
directly to the Z4
II
and Z8
II
.
Two connections are required: the paging mic audio signal
should be connected to the Paging Mic Input (
6
on page
9-
Rear Panel Description
) and the control cable to the Zone
Access port (
9
on page 9).
Connecting a PM4/8/12/16 paging mic
These microphones are equipped with both digital and
analogue paging interfaces; the Z4
II
and Z8
II
use the
analogue interface. PM microphones are available in 4, 8,
12 or 16-zone versions; the installer should be sure he/she
understands how paging zones correspond to mixer zones
before commencing wiring.
Standard two-core screened audio cable may be used for
the audio signal, and stranded multicore cable with an
overall screen for the control cable. The number of cores
required in the latter will be determined by the model of PM
microphone being used and whether the mixer is a Z4
II
or
Z8
II
; however, note that one additional core will be required
if the PM Series microphone is to be powered from the
Zone Mixer.
Connections on the PM microphone are made via the
rear cable access glands and screw terminal blocks on
the internal PCB (TERM1, TERM4 and TERM8 in this
case). Full connection details and notes on power supply
considerations can be found in the PM Series Installation and
User Guide.
fig.18
shows both the cable connections between a PM8 and
a Z8
II
. Note that DC power supply connection will not be
required if the PM microphone is powered independently
(either by a local PSU or via the CDPM digital network from
another PM unit).

For individual zone paging as described above, the paging
mic priority trigger should be selected to ‘SW’ by moving J5
on each zone sub-board. See page 17
(
Paging mic priority
) for
further information.
