Systems with multiple paging microphones
Connecting a single Cloud PM microphone to a host mixer is quite straightforward.
If more than one microphone is required in a system, various additional factors need
to be taken into account. As far as systems with multiple PMs are concerned, most of
these factors are already covered elsewhere in the manual. The following information
may provide some additional guidance.
NOTE: The BUSY LEDs on ALL the microphones in a system illuminate while paging
(or messaging on SA models) is taking place, regardless of which microphone is being
used.
System Interconnection
Multiple PMs* should be interconnected in ‘daisy-chain’ fashion via the Digital Paging
Interface, using CAT-5 cable and RJ45 connectors. In the following description,
note that the ‘last’ PM refers to that connected directly to the host mixer, and the
‘end’ or ‘first’ PM refers to that farthest from the mixer in terms of the daisy-chain
interconnection (which may not be the same thing as the microphone which is the
greatest physical distance from the host mixer).
The CAN PORT OUT of the PM at the ‘end’ of the network is connected to the
CAN PORT IN of the next, whose CAN PORT OUT in turn is connected to the
IN of the next, and so on. The ‘last’ PM in the chain is then connected to the mixer,
either by a further CAT-5 connection from its OUT connector to the Digital Paging
Interface input on the host mixer, or via the analogue interface using separate audio
and access cables. The following examples illustrate some typical situations.
