Connecting a PM1 paging mic
The PM 1 is a simple, passive paging microphone suitable for
situations where announcements are always made to the
same zone(s). It can be connected directly to Z8
II /Z4 II zone
mixers, the control cable being wired to the pin(s) of the
Zone Access port corresponding to the zone(s) in which
announcements are required. Any or all of the zones may be
paralleled if multiple zones need to operate from the PM1.
An alternative method for achieving paging to all zones is
to ignore the control cable altogether and set the paging
priority trigger for all zones to VOX. By doing so, it is the
presence of an audio signal from the mic itself that triggers
the priority circuitry. See page 17 (Paging mic priority) for
further information.
Either a single 2-pair individually-screened cable may be
used (this gives the neatest finish), or two separate standard
microphone cables. Full connection details can be found
in the PM1 Installation and User Guide. Note that the PM1
does not require DC power.
Connections on the PM1 are made via the rear cable gland
in the base and the screw terminal blocks on the internal
PCB (U2 and U3). Full connection details can be found in the
PM1 Installation and User Guide.
fig.19 below shows the connections between a PM1 and
a Z8
II . Use of 2-pair cable is assumed; the same wiring
principle is adopted if separate cables are being used for
audio and control.

Music Control
Like many other Cloud products, the Z8 II and Z4 II allow
remote control of music level and source selection in each
zone. The Cloud remote control plates models RL-1 (music
level only) and RSL-6 (music level and source selection)
provide an elegant solution, though control via a DC voltage
from third-party systems is also possible (see page 19
-
Control of music source and level via DC).
Both types of plate connect via the Music Control Port
for the relevant zone (see
13
on page 9 - Rear Panel
Description). This connector is a 3-pin 5 mm-pitch screw
terminal type. Please refer to page 19
(RL-1 & RSL-6 remote
control plates) for additional information regarding cable
lengths, etc.
Connecting an RL-1 remote control plate
Wire the remote control plate as shown below. Either
single-core screened or twin-and-screen cable may be used;
in the case of the latter, ignore one of the cores. Maximum
reliable cable run is 100 m.

Before the RL-1 will operate, the zone’s Music Control Port
must be enabled by setting the adjacent 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. As
music source selection will still be required from the mixer’s
front panel when an RL-1 is in use, the REMOTE setting
may be overridden for the source selection control only by
moving internal jumper J1 on the sub-board for the zone in
question. See page 23
(PCB Jumper location and settings) for
location of internal jumpers.
