Z4-8MK4 Installation and User Guide v1.2 15
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. However, if this method is to be employed, the mating
multipin connector must be left plugged into the PAGING
ACCESS SWITCHING port, with the pins corresponding
to all the zones that the PM1 is to address connected to 0 V.
See page 19 for further information.
Either a single 2-pair individually-screened cable may be
used (this gives the neatest nish), or two separate standard
microphone cables. 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.
The diagram below shows the connections between a PM1
and a Z8MK4. 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 Z8MK4 and Z4MK4 allow
remote control of music level and source selection in each
zone. Cloud remote control plates from the RL-1 Series
(music level only) and RSL-6 Series (music level and source
selection) provide an elegant solution, though control via a
DC voltage from third-party systems is also possible (see
page 22).
Both types of plate connect via the REMOTE SOURCE +
LEVEL port for the relevant zone (see [16] on page 9).
This connector is a 3-pin 5 mm-pitch screw terminal type.
Connecting an RL-1 Series 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.

REMOTE LEVEL CONTROL WIRING
RL-1
SINGLE-CORE SCREENED CABLE MAY BE USED
Before the RL-1 will operate, the zone’s REMOTE
SOURCE+LEVEL port must be enabled by setting the
adjacent push-button switch ([18] on page 9) to REMOTE
(i.e., pressing it in). In this setting, the zone’s front panel Music
Level and Music Source 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 26 for location of internal jumpers.
