Bruce Brown from Mental Media who was heavily involved in a variety of aspects of the design and delivery of the project, says the design process selected the key elements from the Vietnam era to include an Iroquois helicopter, an Armoured Personnel Carrier, the operations bridge from the guided missile destroyer HMAS Brisbane and the Long Tan AV Theatre, together with a diorama and "The Trench Experience" from the Korean War. Fitting all of this and the assignments of the remaining 35 years into the confines of the existing 1200sq.m ex-administration and ex-gallery space was another challenge.
The design criteria was developed with significant involvement of the in-house AV Section to ensure the new exhibits were easily operated and supported, utilised common components and were designed on an infrastructure base that was flexible, reconfigurable and maintainable.
The AV Section specified a theatrical style lighting patch system with all lighting outlets returning to a pair of centralised patch panels providing "any outlet to any dimmer." This proved very useful during the Stage 3 commissioning where a level of flexibility was available without the need for electricians.
Two 72 way LSC iPatch patch panels were wall mounted for the patching and test functionality. In order to develop a high level of support, the LSC iPRO dimmers were suspended on hook clamp mounts, like truss dimmers, but sitting against the wall, hanging from short pieces of horizontally mounted 48mm OD pipe.
"The LSC iPRO dimmers, supplied by Total Concept Projects, were selected for their 13 Amp load capacity and pulse-transformer fired dimming, providing smooth and reliable dimming no matter whether the load is fluorescent, motors, transformers or extremely low wattage," says the company.
"With the close proximity to the 30 AV systems operational in these galleries, the high quality of iPro's inductors and filtering was essential to keep all systems clean and quiet," the company adds.
Also important to the installation was the ability to program basic scenes into the dimmers as back ups, allowing the exhibits to remain dressed and open to the public should the main AV control system fail.
