Top Marks For New System

Tormead School is an independent girl's school in Guildford, Surrey, so naturally we were chosen to update a very tired Bose speaker system in their dedicated theatre.

The room had changed quite a bit since the original installation now having a large balcony to the rear of the hall. This was causing ‘dead spots’ at the rear of the hall on both upper levels. The main criteria were ease of use and high sound quality with even coverage at any sound level.

We used a pair the Martin Audio CDD15W speakers for the main area with two CDD6W as infill below the balcony and another two on the upper level. The excellent Martin Audio DX0.5 DSP was used to fine tune and time align the system. Powered by Powersoft amplification the results are outstanding, with perfect coverage for the whole crowd no matter where they are sitting.

To keep it as flexible as possible we used an Allen and Heath GLD-112 with the AR2412 Audio Rack. We fitted data sockets at the back, and upper levels of the hall and added a WiFi router so the mixer could be controlled wirelessly using an iPad app. They had a PC that was used frequently but had poor audio quality. To get the very best sound we ran a balanced signal from a USB audio interface to the audio rack. We permanently installed four Audio Technica ES4021 hanging microphones on the stage and these exceeded expectations. Cardioid condenser microphone were also supplied for maximum flexibility.

The teachers at Tormead took to the Allen and Heath GLD-112 mixer very easily and were using it to its full potential within hours.

The installation took place during the summer holidays as the room is used two or three times a day during term time. We are sure they will have many happy years of use for the wide range of events they have.
