Audio Light Systems were selected to design and install an upgrade to the infra-red assisted listening system at the Edinburgh Playhouse.
The objective of the upgrade was to increase the coverage in order that people with hearing disabilities could enjoy the performance at any seat. To achieve this, the original 2 watt radiators were replaced with 5 watt units. To overcome the lack of signal at the front of the stalls two new 5 watt radiators were installed at high level on the proscenium out of the way of temporary sound and lighting rigs. Four of the original 2 watt radiators were re-used in the rear stalls and balcony to reinforce the signal.
