Holy Family School Hall Project

The Project

Holy Family School in Addlestone approached SignalmanAV with the intention of initially receiving 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Although they had a solution in place, it was fairly old, the cabling was out of date, the audio was quiet and the projection system was difficult to see and maintain.

This surrey based school were already well known around the area for their approach to technology. They already had an immersive styled image room with 4 projectors providing imagery around a curved wall. This room is also used by other local schools. So you can imagine that the school has similar plans for their new School Hall AV solution.

Required Solution

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

Their  main requirements consisted of two BenQ laser projectors to provide a clear crisp image in a cinema style environment. The image required was approximately 8.5 metres wide by 3.5 metres in height.

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.
