Solution
Because we were involved in the original remodel we were able to negotiate the potential pitfalls of the restrictive cable pathways. As for the request to reuse equipment, we had anticipated the prospect of a future system update when we designed the original system, so we were able to reuse some of the more expensive system components in our new design.
Some of the cabling challenges with the new system were overcome by leveraging components that could utilize the existing cabling and infrastructure. Others were addressed by painstakingly isolating and removing obsolete wiring by disassembling construction features in a way that allowed for easy restoration.
The new system combined the features added after the initial 2011 project, simplifying control by the sole system operator. Complications that existed relating to guest and public commentary were also eliminated in the upgrade.
