Small Paging System

Small Paging System

Small paging systems have a number of unique requirements, including:

~ Push to talk paging station that allows paging to a single zone, a group of zones, or all zones
~ Paging priority
~ Indication of whether the system is busy or available to page
~ Telephone paging
~ Processing and EQ on all microphones and outputs

This configuration accomplishes all that...

To meet the specifications of the paging system the BLU-10 programmable remote control is used as the page routing interface. By utilizing Push to Talk (PTT) microphones and the control input ports on the BLU-16, logic objects can be used to create conditional routing and muting.

The BLU-10 is an Ethernet device and will connect into the control network or an existing Local Area Network (LAN). All of the BLU-10 remotes are programmed and configured using HiQnet™ London Architect™. As the software has a drag and drop interface, it makes it very simple for the designer to configure the paging stations.

The BLU-10 is programmed to display the zones that are available to page. For example, if it is not a requirement to page a certain zone (such as the manager’s office) then that zone is simply not displayed on the BLU-10.

Presets can be set up to group certain zones together making it simple and quick for the user to make a page to multiple zones.

The BLU-10 can be used to restrict access to any given control screen. This can be used to prevent certain users from paging into selected zones.

All of the paging microphones are connected to the Soundweb™ London BLU-16 which handles all the processing for the signals. Parametric EQ, high pass filters and compression are applied to each microphone signal to ensure the highest quality of sound. A Ducker is then used to provide priority for the telephone paging over the PTT paging stations. The ducker allows the PTT microphones to be ducked down in level while the telephone paging is active. After the telephone page has ended, the PTT microphones will ramp (fade) up gradually or quickly in level depending on programming.

Utilizing logic objects, the user can drive LEDs from the control ports on the BLU-16 to indicate the system is available to page, or that a page is currently in progress.

At the end of a page, any routing that the user had selected is reset.

Additional sources, paging microphones and output zones could be added to the system if you choose to use a BLU-80 and BLU-32. Any background music within the system could be automatically ducked during a paging announcement.
