MCEC updates audio network protocol


The Melbourne Convention and Exhibition Centre (MCEC) has undergone an upgrade to a networked audio system. The upgrade was completed by avt and featured a BSS solution from Harman.

‘MCEC approached us to support them in the development of a robust, self-sufficient solution that would upgrade its digital signal processing capabilities and minimise audio issues during events,’ said Graham Barrett, head of strategic partnerships and innovation at avt. ‘After evaluating their requirements, we recommended Harman’s networked AV solutions to compose a system that would provide the necessary flexibility and allow them to easily expand the platform in the future.’

BSS’ redundant BLU link protocol has been employed for the network. It was chosen for its adaptability and capacity to incorporate multiple network streams of different types while simultaneously carrying all audio signals. The protocol comprises two cables and automatically switches if one of the network legs fails.

‘We’ve invested in AMX control systems since our beginning to manage the operations of all our networked devices,’ said Michael Walker, infrastructure and equipment manager at MCEC. ‘We needed to switch from our outdated copper network due to its inherent weakness, and we wanted a system with the strength of a modern network protocol. It had to be capable of supporting a live production environment without a single point of failure. We’re pleased to say that since installing the new system, we haven’t had a single incident of network failure or dropout without the redundant link automatically solving the problem, and our customers haven’t faced any audio issues in their event spaces.’
