Latest News - MAC-nificent Tyger Valley
Designing and installing a system suspended very high above the ground and that could cope with the high level of natural ambient light in one of Cape Town’s premier shopping centres was a challenge, but one that Martin and Litec could meet.
It is said that good things come to those who wait, which was certainly true for Electrosonic, which was contacted more than a year ago by Marcel Zandberg of Slave Distributors in Cape Town, regarding a top secret project that was in the pipeline.
At the time, all Marcel could tell Electrosonic’s Entertainment Lighting Manager, Bruce Schwartz, was that they needed the brightest lights that Electrosonic could offer. That was the start of what became a challenging project at the Tyger Valley shopping centre in Cape Town. Situated in Bellville, the Tyger Valley Shopping Centre comprises 89 222m2 of retail area over three levels, offering everything from retail stores to restaurants. The centre also provides entertainment for the whole family in the Arena, with regular events for children, a variety of exhibitions, product launches, celebrity performances, competitions and annual festive season activities.
Raising the roof
The original lighting in the Arena was supplied by Electrosonic more than 12 years ago, and when the food court and entertainment area was to be reconstructed with a much higher roof, Electrosonic was asked to quote on the new lighting system. The brief was for a system that could be flown very high above the ground and that could cope with the high level of natural ambient light. It also had to be flexible enough for parts of the system to be utilised for smaller functions.
This proved to be quite a challenge, given the multi-level nature of the Arena. Additional challenges in the brief were that as little as possible of the infrastructure was to be visible, and there was to be no access to the roof via the cat-walks. Marcel drafted a plan and Bruce flew to Cape Town to produce a complete design that was submitted to the consulting engineers. Over the following month there was a great deal of communication back and forth before a final CAD drawing was approved and Slave Distributors was officially appointed on a design and supply contract.
The design incorporated a general lighting setup for the lower levels, a main truss rig approximately 20 metres from the ground, and two trusses left and right of a large LED screen. All this was to be controlled via a control desk that could be plugged into a CAT 5 network. A DMX distribution system was needed for the various areas and a media server was to be installed.
Lower and mezzanine levels
The design of the system consisted of four pre-wired lighting bars for the 1st and 2nd floor mezzanine levels. Marcel reconditioned a number of PAR 64 1000w fixtures from the previous installation and 2 x 12 Way 3KW Electron dimmers were installed in the rack room.
These internally wired bars were custom designed by Electrosonic with special mounting brackets on a radius with both Hot Power and DMX 512 outlets to enable 48 Versalight RGB High Power LED Cans to be spaced out around the two levels. These were to be used for day to day illumination because of the low running cost of LED fixtures.
Main truss grid
Marcel had only four hanging points from which to suspend the main truss grid. The challenge was to find a high load truss to span the 16 metre x 8 metre rectangular truss. After examining loading tables, he chose the Litec QL40 high load truss which can be loaded to 850 kg point load across a 16 metre span, with a total distributed loading of 1 900 kg across the span. Four 1-ton CM Lodestar motors were installed to enable the truss to be lowered and raised for maintenance. A Control Freak Motor Controller designed by Electrosonic was also installed.
The main truss was warmed with 16 x Rige standard LED Cans to add a bit of colour, and to overcome the height and daylight issues, the Martin MAC III and Martin MAC 2000 XB were chosen as the workhorses. These 1500w units were the first to be sold in South Africa and proved to be a fantastic choice. There are very few large format moving light profiles and washes on the market and the tried and tested MACS are ideally suited to this type of application.
Screen left and right bars
In order to provide some backlight as well as to illuminate the mesh behind the LED screen, 2 x 5 metre Litec QX30 trusses were hung off 4 x ½ Ton CM Lodestar Motors. On each 5 metre truss were 2 x MAC700 Washes and 2 x MAC700 Profiles, with additional Rige LED Cans as Truss Warmers.
The brief was to have the ability to control the lighting and video system from 7 plug-in points. The best way to do this was to use CAT 5 and to create an ARTNET network. The Martin Ether2DMX8, a marvellous unit that is not widely known, was placed in the rack room 70 metres away and 7 x CAT 5 lines were run back via an Ethernet Hub to the Ether2DMX8 box.
The box converts the ARTNET from the desk (with an assigned IP address) to DMX 512 signal and 8 x buffered DMX outs are sent via Martin DMX 3.5 Opto Splitters to the main truss, media server, LED Cans, dimmers and screen trusses. A DMX Switch pack was installed in the main distribution board to turn on the intelligent lights remotely.
Control desk and PC
A requirement of the brief was for the system to be operated day to day without the need to plug in the control desk, which was to be used only for larger events. The solution was to install a MAXXYZ PC system connected via IP to the Ether2DMX8 box. The box switches over to the desk when it is plugged in, or falls back on the MAXXYZ PC for day to day running with cues set up to cater for a variety of functions and events.
An ELO touchscreen was installed to make the recalling of programmed scenes simple and easy. The M1s from Martin was the obvious choice for Marcel when it came to selecting a powerful control desk that was also compact, simple, and easy to use. Not only does it have a clear layout and plenty of playback hardware, but it also integrates seamlessly with all the other Martin gear, with very little configuration required.
