St Albans Primary Hall AV Project

The Project

St Albans Catholic Primary were recommended to SignalmanAV via another school we had recently dealt with. The intention was to initially receive advice and costs for upgrading their existing school hall AV solution.

Although they had a solution in place, it was fairly old, the cabling was out of date, the audio was quiet and the projection system was difficult to see and maintain.

Required Solution

After discussion and various correspondence over a period of a few months. The School elected to proceed with SignalmanAV for the new state of the art School Hall AV solution.

Their main requirements consisted of a bright low maintenance projector to provide a clear crisp image in a cinema style environment. The image required was approximately 5 metres wide by 3 metres in height.

An Audio Solution, to provide good quality surround sound and a portable (but robust) solution to house all of the equipment for the audio and projection solution.

We had a team of 4 technicians installing equipment over a period of 4 days, running cables, installing Projectors, programming hardware and building audio racks to house the hardware.
