ASCL uses Renkus Heinz for Grand Hyatt Hong Kong Grand Ballroom
CHINA: Featuring 24 flexible event venues, Grand Hyatt Hong Kong can host events and meetings accommodating groups of between 12 and 1,200 guests. Located adjacent to the Hong Kong Convention & Exhibition Centre (HKCEC), the hotel’s Grand Ballroom has welcomed some of the most prestigious events over the years as a result of this proximity. The 680 sq-m Grand Ballroom has a pillar-free design and a permanent stage, thus providing its guests with an excellent visual experience. The high-definition full-screen LED wall is multimedia-oriented, providing event organisers the flexibility to change the background in a second in addition to displaying multiple visuals at the same time, thus minimising the production of structural materials whilst saving production and set up costs.
The venue was closed for two months in June 2013 for refurbishments and renovations. Working closely with ihD Ltd on the system design, Hong Kong-based systems integrator ASCL was awarded the contract to supply and install a new audiovisual and stage lighting system for the Grand Ballroom. Like most premier facilities, the hotel management demanded a digital audio solution that would not mar the aesthetics of the venue design.
‘The logical solution was to install a column speaker solution onto the two vertical marble pillars located to the left and right of the stage, but we knew this was not possible,’ commented ASCL’s senior sales manager Tommy Ho. ‘Therefore we opted for two Renkus Heinz IC Live–FR speaker systems to be installed into the surrounding proscenium to the left and right of the stage.’
Simply connected via Belden Cat-6 cabling and powered, the eight 6.5-inch transducers and 1-inch drivers of the stage right system concentrate their energy towards the left hand side of the floor area, thus avoiding any energy splashing back off the vertical column in front of it. Conversely, the IC Live system located to the left of the stage steers its beams to the right hand area of the Grand Ballroom. Covered by fine gauze, both IC Live-FR systems are supplemented by self-powered IC212S subwoofers for low frequency extension.
Installed into the rear overhead control room, a Yamaha LS9-32 console has been outfitted with MY16 CII Cobranet and Aviom 6416 Y2 I/O output cards. ‘Basically, this provides the venue with dedicated speech or music modes,’ continued Mr Ho. ‘For live performances on stage, the hotel technicians can utilise the Aviom F6 mainframe, digital snake and 6416M mic input module, which connects the fold-back system and portable speakers for front-fill sound reinforcement. However, for speeches and paging, we have installed a QSC iCore 250 processor with two I/O frames, which combine to perform all the audio routing and processing in the Grand Ballroom, pre-function area, meeting rooms and back of house areas.’
The entire system is managed and configured via a PC loaded with Q-Sys software in the control room. The centralised architecture provides complete flexibility in which any input can be routed to any output without confused signal paths. In addition to providing many processing and control functions such as crossovers, delays, dynamics, meters, filters and equalisers, the centralised structure can physically locate input and output connections near their sources and destinations using additional I/O Frames. Powered by QSC CX 302V and 108V amplifiers, the pre-function area is served by 10 AD-CI52ST 5.25-inch ceiling speakers, whilst the back of house areas is served by QSC AD-C42T models.
An Extron XTP Crosspoint 3200 32x32 Mainframe was added for providing video connections with a Crestron CP3 system for controlling and managing the lighting, drapes, visual content and other functionality via 7-inch wall mounted touchpanels.
