The installation was managed by Sanecore, who decided to use an Allen & Heath digital mixer as the heart of the whole system, with the addition of multiple digital base stations, in order to satisfy the requirement of room combination and audio synchronization, while providing audio quality superior to any typical A/V matrix.
Four iDR-16 MixRacks were installed, one for an inspection room, one for the emergency command centre, and two for monitoring in the hall. Real time audio communication between multiple rooms was established using Allen & Heath's proprietary ACETM point-to-point audio network technology.
An iLive-R72 Control Surface and two iDR-16 mixers were installed for the PA system in the command centre, and two more iDR-16s were used in two adjacent meeting rooms. Connected via ACE, they manage a total of 64 inputs and 32 outputs, handling various sources, including gooseneck microphones, audio signal synchronised with video, and PC audio signals.
"The powerful digital mixers are connected in one network, and the operating through central control touch panel is so easy with so many inputs and outputs, it's just incredible! Different signals can be transferred, switched between each other and processed easily, and it is convenient to operate via the iLive-R72 surface," commented Li Shuzhi, project manager at Hebei.
