The MPS20 is a 20 button paging or emergency microphone station compliant with EN 54-16, which provide live and pre-recorded message broadcast.The microphone is desk mount and feature a graphic LCD display together with indicators for ‘Power’, ‘Voice Alarm’, ‘System Fault’, ‘Fault’ and ‘Speak Now’. The LCD display provides remote access to the list of active faults in the PA/VA system, while the EN 54 mandated control keys enable navigation through the fault list, and also provide remote fault acceptance and clearance.
OVERVIEW
The MPS01, MPS10, MPS20, MPS30, MPS40, and MPS50 are powerful and flexible paging microphones which can provide live, store-and-forward, and recorded message broadcast into user selected zones, and also provide EN54-16 compliant emergency functions and associated mandatory indicators and controls.
The MPS10/20/30/40/50 units each consist of a MPS01 sloping desk console with a flexible gooseneck paging microphone, graphic LCD display, and silent operation ‘Touch to Talk’ touch pad PTT button, together with one or more additional MPX10 zone selection and control button modules. The number of additional buttons depends on the model, with the MPS10 having ten extra Select buttons, and the MPS50 having fifty.
PA zone selection is provided by the Select buttons or by using the rotary selector and graphic LCD display. There is also a VU bar-graph which displays the microphone signal level.
The MPS range can be connected directly to either one or two ASL audio routers using analogue audio and a serial link. There is also an RJ45 Ethernet IP interface with Power over Ethernet for connection to ASL IP PA/VA systems, and for use with VIPA enabled PC workstations. All interconnecting cabling and the microphone capsule are continuously monitored.
As well as the main microphone gooseneck, there are 3.5mm jack plug connections for an auxiliary audio input, such as for background music, and for connection of a microphone headset. A general purpose local contact input and output enables use with PTT foot switches and external speak-now indicators.
The microphone, and all interconnect cables and the gooseneck microphone are replaceable to simplify maintenance.
The MPS microphone range can be used freestanding on a desk as standard, or can be permanently mounted with the optional mounting bracket. This bracket gives options to mount the microphone flat on a wall, built onto consoles or fixed on desks.
The MPS can be purchased with a fist microphone replacement for the standard gooseneck if required. This is particularly useful if the microphone is console or wall mounted.
Inputs1 and 2 of VIPEDIA-12 support All Call Hardware Bypass Operation. The operation of microphones on these inputs continues in an all-call-only mode in the event of VIPEDIA-12 processor failure or if there is a fault in the DBB connection between units. Hardware bypass operation is supported in DBB and AB system architectures and does not operate over Base-IP or ASL Secure Loop.ANALOGUE INTERFACES
Single Serial + Audio InterfaceThe standard connection method uses the Router 1 Microphone Port connected direct to a single ASL audio router.Dual Serial + Audio InterfaceIf the MPS is used with a single audio router, then both the Router 1 and Router 2 Microphone Ports can be used, in order to provide dual redundant cabling between the MPS microphone and the router.Dual Serial + Audio Interface / Multiple RoutersIf the MPS is used with a PA/VA system which has two or more VIPEDIA-12, then both the Router 1 and Router 2 Microphone Ports can be used, one connected to each ASL Audio Router.This option is supported across DBB, Base-IP, ASLSecure Loop and AB architectures. Hardware bypass is only operational across DBB or AB architectures in multirouter systems.Single Interface / Paging & Local MusicIf the MPS is used with a local music source connected into its rear mounted 3.5mm audio input socket, then both the Router 1 and Router 2 Microphone Ports can be used, one for the music feed and one for the microphone.This will provide simultaneous operation of the microphone to make a broadcast to some PA zones while the music feed continues to be played into other PA zonesIP INTERFACES
Single IP Interface (POE Power)The standard VIPEDIA-12 microphone interface can also be configured to operate over Ethernet. Functionality is identical to an analogue interface MPS. IP microphone preannouncement chimes are configured to be played locally from the MPS microphone.Single IP Interface (POE Power) / VIPA InterfaceAn IP connected MPS microphone can work as a workstation microphone with a VIPA equipped ASL or third party IP PA Control System.Broadcasts from the MPS are normally controlled via the workstation GUI; however the MPS microphone can operate independently.IP FALLBACK MODEThe analogue and IP interfaces described above, rely on a host device (usually a VIPEDIA-12 or VIPA software module) for operation.If the host device becomes unavailable, it is possible to configure the MPS microphone to continue in limited operation ‘Fall-back Mode’, whereby it can address zones on multiple devices directly over an Ethernet network without the need for a host device.In IP Fall-back mode, iPAMs can be addressed a single zone. VIPEDIA-12 zones can be addressed individually or as a group as necessary.
