11-Zone PA Rack Build for Council Offices

We’ve recently completed another multizone PA system rack build for one of our installation customers, enabling them to spend less time on site and with the peace of mind that the equipment and rack are correctly working.

Our client, working on a local council building, needed a reliable paging system to operate over 11 zones.

We agreed on a system design based on three TOA VM-2120 five zone mixer amplifiers with each amp providing a total of 120 Watts into 5 zones.

By setting up the amplifiers to run as one Master and 2 Subs, this provides the required number of zones whilst having some spare zones available for future expansion of the system. (Up to nine VM-2120s can be linked in this way for expansion potential of up to a total of 50 zones.) The Master / Sub mode is set internally via function switches and the three amps are simply daisy chained via the RJ45 Link connectors.

The Master amp handles the overall logic: Priority between microphones, BGM, telephone paging, and remote microphones for example, whilst the Subs provide the extra zones, all working together as one coherent system.

The convection cooled amps have been mounted into a Lande Proline PR12U6060-BL 19" equipment rack with vent panels in between each amp to aid ventilation. Working on these racks is a dream thanks to the removeable and lockable side and rear panels as well as as a quick release hinged door. We used a 12U rack in this project but it's available in a range of heights from 7U to 20U all with 2 depth options of 450mm or 600mm. It can be used on the floor / desk (with optional casters / feet) or it can be wall mounted - the removeable rear panel is fixed to the wall before lifting the filled rack into place.

Paging across all 11 zones is achieved using one TOA RM-200MS 10 zone paging microphone with the RM-210S 10 zone expansion keypad covering the 11th zone and any extra zones added in the future. Up to 4 extension units can be used with one RM-200M microphone giving a total of up to 50 paging zones accessible from one microphone station.

Penton RCS-6T ceiling speakers were used throughout the Council departments and offices, just one of the scores of ceiling speakers we offer! It's a 6", 6 Watt, quick fit, twin cone celing speaker finished in white and is available with or with firedome.
