Connecting a paging mic via the analogue
interface
Two connections are required: the paging mic audio signal
should be connected to the MIC 1 INPUT
15
. and the control
cable to the 6-pin MIC 1 ACCESS CONTACTS port
18
. The
pinout of this port is:

reference
Standard two-core screened audio cable may be used for
the audio signal, and stranded six-core cable with an overall
screen for the control cable. (Note that ‘-SA’ versions of PM
Series microphones cannot be powered by the 46 Series, and
require an external PSU.)
If connecting a PM Series microphone via the analogue
interface, use the rear cable access glands and screw terminal
blocks on the microphone’s internal PCB (TERM1, TERM4 and
TERM8 in the example shown below). 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 PM4 and a 46 Series unit. Note that the DC power
supply connection will not be required if the PM microphone
is powered independently by a local PSU.
Connecting a Cloud PM1 paging mic
The PM1 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 the analogue
paging interface, the control cable being wired to the pin(s)
of the MIC 1 ACCESS CONTACTS connector 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.
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 46 Series mixer-amplier. Use of 2-pair cable is
assumed; the same wiring principle is adopted if separate
cables are being used for audio and control.
