These Cloud desktop paging stations are wired using standard CAT5 connections and may be linked together to form a network with a large number of stations, controlling multiple zones. Interfacing to mixers or mixer-amplifiers can use ‘standard’ signalling, or use Cloud’s proprietary connection. The system uses analogue audio and digital control and interlocking.
PM4, PM8, PM12 and PM16 are a range of paging microphones with either four, eight, twelve and sixteen zone buttons respectively. Each model has a gooseneck microphone with cardioid capsule and integrated compressor. Each has a number of electronically latching zone selection buttons, depending on model, and momentary buttons for talk, call-all and to clear the current selection. Each has four ‘group select’ buttons to select pre-assigned groups of zones which then may be called by pressing the talk button. A ‘busy’ indicator shows when the system is in use. An internal ceramic sounder provides local monitoring of chimes, if configured, to avoid talking ‘over’ the chime.
Up to 32 paging microphones may be looped together using RJ45 connectors and CAT5 cable to carry access data and audio. Up to 16 zones are supported by the system. It is possible to create a system with a total cable length of up to 1000 metres. To maintain compatibility with existing and third party equipment the paging microphone can generate industry standard ‘Short to ground’ access.” The interface has sixteen-zone connections and a screw terminal output to the amplification equipment.
Configuration is set using internal jumpers, with the exception of zone barring and programming groups. Display set: The zones addressed by a paging can be shifted to any block in the sixteen available zones. For example, in a system with two PM4s, the first paging microphone can page zones 1 to 4, the second can be set to page zones 2 to 5. Auto-reset: With auto reset enabled, the display is cleared after a call, with auto reset not enabled the zone selection is retained after a call. Lock group: This prevents the group buttons being reprogrammed. Priority: There are two priorities, normal and high. A high priority paging microphone can interrupt paging from a normal priority paging microphone. NVM reset: Returns the paging microphone to factory settings. Chime select: Chooses one of the four chime tones. Chime on/off: Enables or disables chime. Internal chime: Enables or disables the internal chime sounder. Zone barring: Disables a zone button on an individual paging microphone. The four group buttons allow paging groups to be programmed into each paging microphone.
Gooseneck length: 300mm, standard. Capsule type: Condenser. Polar pattern: Cardioid. Dimensions (WxHxD): 245 x 65 x 170mm, without microphone. Weight: 1.2kg. Power source: 9-17V AC or 12-24V DC, connected via a 2.1mm coaxial power socket.
Optional accessories: Each microphone station requires a power supply either from host equipment (one unit powered per host) or accessory power supplies (see user manual for further details on restrictions). Lugged case or lap-top style power supplies are available; or 23-991 lugged case has an IEC C8 fig-8 mains inlet, 23-993 laptop style has an IEC C14 mains inlet (cable not supplied).
In addition to the functionality of their non-‘SA’ versions, these paging microphones have the added ability of playing back pre-recorded messages. The messages, which should be pre-recorder on a computer can be of any length within the given capacity of the media used, and are stored on a SD card of up to 2GB (SD), or 32GB (SDHC). The card can be inserted in the underside of the console vie a hatch secured with two pan-head hex-socket screws. Compatible file types include MP3 and WMA, with sampling frequencies of 8/11.025/12/16/22.05/24/32/44.1/48kHz. PM4-SA can playback up to four pre-recorded message, and the PM8-SA can playback up to eight. In addition to the messages, up to four (PM4-SA), or eight (PM8-SA) pre-announcement chimes can be used.
