“Our radio mic replacement project was actually two projects that we ran in parallel,” said Yuval Angel, AV Production Manager at GCCEC. “The first was to replace all of our roving, roadcased radio mic racks, and the second was to replace the site-wide radio mic system we use to cover the facility as a whole, including its spectrum management and networked audio distribution.”
“With the Centre needing to upgrade RF through the whole building, the high channel count, and the Gold Coast’s spectrum background, we felt that Shure Axient Digital was the only option,” said Josiah Kerridge, Sales Specialist at Brisbane Sound Group. “We helped organise A/B testing against the incumbent radio mic brand, and the GCCEC staff decided that Shure Axient Digital represented a step above in both RF and
Jands is Australia’s leading distributor of professional lighting, sound and staging equipment.”
The GCCEC has seven roving radio mic racks that are self-contained systems with four channels. Each rack consists of two handheld and two bodypack transmitters, mics, receiver, aerials, and network connectivity. All seven of these racks are now fitted with an AD4Q 4-channel receiver, two AX2 and two AD2 handheld transmitters with SM58 mic capsules, two ADX1 and two AD1 bodypack transmitters paired with TwinPlex lavaliers, two UA874WB active directional antennas, an SBRC battery charger, and AD610 ShowLink access point, which gives technicians the ability to make changes to gain, sensitivity and other parameters on the transmitters wirelessly, in real time. Six of these racks have the Dante outputs pre-routed to specific digital mixing consoles.
A further four racks have been fitted with an AD4D two channel receiver, two AD2 handheld transmitters with SM58 capsules, two AD1 bodypack transmitters with TwinPlex lavaliers, two UA874WB active directional antennas, and an SBRC battery charger.
All systems are networked, and a central computer running Shure’s Wireless Workbench software sends a live scan to a screen in the AV storeroom that keeps techs updated on all RF activity in the building.
“The AXT600 Axient Spectrum Manager is the brain of our system,” says Yuval 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 is almost totally automated. We don’t need to constantly 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 current and taking into account what’s in the space. When we have someone like media come in to the building that hasn’t let us know they’re using RF and what frequency they’re on, it manages it by itself.”
