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

MK3

 or Z8

MK3

however, note that one additional core will be required if the 
PM Series microphone is to be powered from the Zone Mixer. 
(Note that SA versions of PM Series microphones cannot be 
powered by the Z4MK3 or Z8MK3, and need an external 

PSU).

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.
The diagram below shows both the cable connections 
between a PM8 and a Z8

MK3

.

 Note that the DC power 

supply connection will not be required if the PM microphone 
is powered by a local PSU.

This connection only required if 

the PM Series microphone is to 
be powered  from the mixer 

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 16 for further information.

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

MK3

/Z4

MK3

 

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. However, if this method is to be employed, the 
mating multipin connector must be left plugged into the 
PAGING ACCESS control port, with the pins corresponding 
to all the zones that the PM1 is to address connected to 0 V. 
See page 16 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.
The diagram below shows the connections between a PM1 
and a Z8

MK3

. 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

MK3

 and Z4

MK3

 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 19

).

Both types of plate connect via the REMOTE SOURCE & 
LEVEL port for the relevant zone (see [13] on page 9

). 

This connector is a 3-pin 5 mm-pitch screw terminal type.
