The facility deploys four Soundweb London BLU-160 devices and four BLU-BOB 8-channel output expanders, placed on the Soundweb London fault-tolerant digital audio bus. The two mobile racks are configured identically and the digital audio bus audio channels can be connected at four different points. Feeding the BLU-BOB devices, source inputs include four wireless commentator microphones (with pre-programmed ducking function), and a small external Soundcraft mixer.
"The requirement was for a new system that would provide even coverage at sufficient volume, with excellent speech intelligibility," said Kain's IT and applications engineer, Iuliu Varga.
One rack is assigned to the first two riding halls and the second to the other two halls, with expandability provided for future outdoor coverage requirements. Since they are identical, the two racks also serve as redundant units.
"The digital audio bus channels don't need any Ethernet switches - only patch panels. We only use Gigabit Ethernet switches in the two mobile racks to connect the BLU-160, touch-computer and wireless access point," added Varga.
Sound reinforcement is provided by JBL CBT 70J/70E and CBT 100 asymmetrical vertical columns, which send highly concentrated sound toward the back of the venue, while down-filling a broader, less concentrated sound to the front of the venue, thereby maintaining constant pattern control. Additionally, 58 JBL Control 29AV loudspeakers, 10 JBL Control 28 loudspeakers and lo 18 JBL Control 25 loudspeakers were deployed in various other areas, all powered by Crown XTi series amplifiers.
