The Oxford Sound Company has recently completed the installation of a voice-reinforcement system at the prestigious Keble College, one of Oxford's high seats of academia. The installation was in the main dining refectory used as a conference facility accommodating up to 200 people, making the use of voice reinforcement essential. "The refectory is a giant reverb chamber with a reverberation time in excess of three seconds," explained Andrew Riley of the Oxford Sound Company. "So we had to specify speakers with a predictable off-axis polar response and position them to achieve an even sound coverage for all of the seated areas." Three pairs of speakers were used, all fed via appropriate delays and equalisers.
