Amsterdam (April 22, 2005)–Built in 1886, the Royal Carré Theatre has been an integral part of Amsterdam’s cultural life for generations, and a 28 million Euro rennovation effort on the venue began in 2003. During this time, Ron Zevenhoven of AV installation company Session Sound began a series of auditions with Dutch touring sound engineers, designers and other technical staff to assess their requirements of a fixed sound-reinforcement system. The result was a system based around L-Acoustics loudspeakers and XTA loudspeaker management processors.
Zevenhoven’s L-Acoustics loudspeaker system comprises of 12 dV-DOSC line-array modules as a centre cluster, two sets of three 112XT enclosures as balcony delays and front-fills, and two pairs of 115XT boxes as in-fills for the stalls area. Along with that, Dutch distributor TM Audio supplied two XTA DP226s and a DP224. The former offers delay, parametric EQ, filtering and limiting facilities in a two-in, six-out package, while the latter offers the same processing capabilities in a four-output configuration.
“We’re using one DP226 to manage the centre cluster and the second to manage the balcony delays, while the DP224 looks after the in-fills,” said Zevenhoven. “The presets are the normal ones from L-Acoustics, and we use XTA’s AudioCore software to give us remote control over all the parameters.”
All three XTA units are installed in a backstage rack, along with the Windows-compatible laptop PC that runs AudioCore. “The PC is always online, and when you take the laptop out into the auditorium,it effectively acts as a wireless tablet–the CPU is not used,” explains Zevenhoven. The wireless link is useful for allowing visiting FOH engineers to tailor parameters to the needs of their particular production. But Zevenhoven makes full use of AudioCore’s password protection facilities to ensure that key programming elements remain out of bounds, even for experienced engineers.
“For each production, we decide whether to give the visiting engineer AudioCore to play with,” said Zevenhoven. “There is so much processing power in these XTA boxes; they give you a very wide degree of control over things like limiting which, if you don’t know what you’re doing, could alter the gain structure and really affect the integrity of the line source.”
