Network Safe
A key element of the system is that all audio is managed as AES3. Utilising a version of the power over Ethernet protocol (POE) we can transparently pass our signal over existing structured networks, making the whole system integration easier and more cost effective. At the relevant paging zone, simply plug the front end unit into a suitably assigned network socket, and that's it! As the audio is digital AES3 it will not affect other network traffic, and other network traffic will not affect it. All connections are transformer isolated and Ethernet safe. Any cross connections with other network equipment will not cause any damage to either unit.

Zone Controller
The Zone Controller is connected via CAT5 on a normal structured network. This connection passes audio, data and powers the controller. It also allows connection of the microphone (12v phantom) and the selection of the paging zone. The system is available as standard with our pre-selected Audio Technica condenser microphone. After extensive testing this mic is found to offer the best performance verses cost results. This mic also impressed as it was particularly resistant to GSM interference. If you would like to use an alternative mic the system can be ordered without microphones. 

The Zone Controller is available as a single unit, or as a 2 part system, separating the zone selection, from the mic and paging button. This is particularly useful if desk space requires a smaller foot print for the mic paging unit.

The sixteen paging zones can be selected in any combination, indicated via a green LED. Once selected, the paging button will send the audio to all selected zones. There are four preset buttons to set up pre-selected zones for paging with a single button press. There is an 'arm' button that must be selected before paging to avoid accidental use. If a zone is already being used it will indicate with a red LED. The operator then has the option to continue the page and mix their audio with the audio already present, or wait for the other announcement to finish.

Glensound Digital Control
The onboard DSP devices allow control over the audio. There is digital compressing and limiting, parametric EQ, and other filters. The Glensound engineers have also developed a purpose built PA frequency shifter technology called, 'PG-Shift'. This constantly monitors audio input for signs of howl round and phase shifts the audio signal by 90 degrees and takes it up 4 dB. This automatic process operates in the background and is continuously making adjustments. The result is the ability to have gain levels significantly higher than a normal system, resulting in higher output levels before the onset of feedback. In use the system is therefore clearer for all people listening and more pleasing to listen to due to the lack of howl round.

3U Subrack
The subrack accommodates one of four system cards:

1. Mic link. This is the interface card to the front end. Connection is via standard network structured wiring. This link powers the Zone Controller and transfers the audio signals.
2. Mix. This zone output card carries out the zone switching or mixing and passes the 16 x AES3 audio outputs on 4 x RJ45 sockets.
3. Ethernet. This provides management information. Any faults on the system are emailed to alert a selected address. It also contains DC loops for further control options.
4. Power Supply. The rear panel can have a second optional redundant power supply added.

Applications
The MZP-16 is for multi zone paging applications where the audio quality needs to be loud and clear, and of the highest possible standard. This could be to be in keeping with the environment for which it is used (high quality hotels, government buildings, broadcast centres, etc) or where the clarity and quality of the audio is paramount (city trading floors, for security announcements at airports, the local bingo hall!)

On Site Optimisation
The GS-MZP16 can further be optimised by a site visit from an acoustician. This allows specific tuning to the acoustics of the room. This was carried out when this system was installed at the HSBC trading floor in Canary Wharf, and resulted in a system that over performed! 

Customisation
Due to the way we manufacture our products, there are options on the system. This could be the physical unit, for instance in different size boxes to fit into particular spaces, or top panel only to fit into existing hardware. The nature of the zone control, number of zones, button layout, etc. can all be considered. Please talk to us about your specific requirement.
