Heriot Watt University contacted Audio Light Systems to carry out projector, screen and infrastructure installations throughout the Edinburgh Campus. The teaching spaces were using small portable systems as teaching aids, which could be awkward and time consuming to set up. New permanently installed NEC projectors were chosen to replace the portable units due to the quality and the 3 year hot swap warranty. The Hotswap warranty meant that if any project malfunctioned, NEC would swap the unit with a replacement in the first 3 years. No projectors have ever been replaced.
