The Gold Coast Convention and Exhibition Centre (GCCEC) is one of the largest performance venues in Australia with four exhibition halls, 22 meeting rooms and a main arena with a capacity for 6,000 people. As the GCCEC wanted to update its radio microphone and RF management equipment, it turned to its supplier, Brisbane Sound Group, and distributor Jands, who chose the Shure Axient Digital radio microphone systems to be deployed throughout the facility.

‘Our radio mic replacement project was actually two projects that we ran in parallel,’ explained Yuval Angel, AV production manager at GCCEC. ‘The first was to replace all of our radio mic racks, and the second was to replace the site-wide radio mic system we use to cover the facility, including its spectrum management and networked audio distribution.’

The GCCEC invested in seven roving radio mic racks. Each of the racks has two handheld and bodypack transmitters, mics, receivers, aerials and network connectivity. These are fitted with a Shure AD4Q four-channel receiver, two ADX2 and two AD2 handheld microphone transmitters with SM58 mic capsules. Two ADX1 and two AD1 bodypack transmitters are paired with TL47 TwinPlex lavaliers in black, two UA874WB active directional antennas, an SBRC battery charger and AD610 ShowLink access point to give the technicians the ability to make changes wirelessly. Six of the seven racks have Dante outputs pre-routed to specific digital mixing consoles. An additional four racks were set up with an AD4D two-channel wireless receiver, two AD2 handheld transmitters with SM58 capsules, two AD1 bodypack transmitters with TL47 TwinPlex lavaliers, two UA874WB active directional antennas and an SBRC battery charger.

The radio mic system consists of two channels of ADX2 handheld transmitters. Four UA860SWB wideband antennas were installed around the building and an AD4D receiver is patched to a matrix system. Two AD610 Showlink access points help to keep the mics in range for wireless management with an AXT600 Axient Spectrum Manager in the centre of it all.

‘The AXT600 Axient Spectrum Manager is the brain of our system,’ added Angel. ‘It is continuously scanning the building and can assign frequencies to any Shure wireless equipment we’ve connected to our AV network. It takes the hard work out of managing RF and it’s almost totally automated. We don’t need to create new frequency plots when we get external parties like the media bringing in radios mics. We can make a plot in advance and if anything is omitted or wrong, Axient Digital works around it. It’s always taking into account what’s in the space. When we have someone come into the building that hasn’t let us know they’re using RF and what frequency they’re on, it manages it by itself.’
