FEATURE: INTERCOMS AND PAGING
“There is no difference if you have one or 100 zones; one or 100 concurrent channels,” observes Rietschel. Barix is by no means the
only manufacturer to be keeping an eye on end-user skill-sets. Introduced at ISE 2013, Apart Audio’s AudioControl 12.8 paging matrix is a step up from the manufacturer’s previous capability of a four-zone matrix or a six-zone 100V paging system. Incorporating DSP processing and control possibilities, AudioControl 12.8 paves the way for Apart Audio to supply paging solutions for up to 16 zones when two matrices are linked together. Significantly, AudioControl 12.8 can also be deployed in three different modes, as Apart Audio/Audioprof sales & marketing director Kris Vermuyten explains: “The out- of-the-box mode where no programming or PC is needed; the installer mode, where only limited parameters can be changed; and the expert mode, where the integrator can configure the complete DSP with EQ, dynamics, macro programming, paging station and wall panel configuration.”
TRILOGY’S GEMINI IS LORD OF THE RING (CYCLE)
Underlining the benefits to be achieved by installing scalable intercoms is the recent deployment of a Trilogy Communications Gemini matrix intercom system at the Royal Opera House in London. John Sparrow, product sales
manager at Trilogy Communications, explains that the spur to upgrade from an old, hard-wired internal comms system was the prospect of staging Wagner’s frankly gargantuan, 14.5-hour Ring Cycle. The eventual result was the specification of three Gemini matrices – each of which can accommodate up to 32 ports, with an IP gateway adding provision to stream bidirectional audio traffic over a further 32 IP channels. “With a production as
complex as the Ring Cycle, the last thing you need in the run-up to opening night is to have to learn a whole new communication system, and that’s where Gemini’s flexibility came into play,” explains Sparrow. “We worked
with the ROH engineering staff to modify our standard lever key panels to ensure that the system remained operational over long runs of old cable. This meant that no physical alterations for new cable runs had to be made to the venerable listed building. We simply enabled our control panels to work on DC rather than AC volts so it could use the existing cabling. Moreover,
to retain the familiarity that operators had become accustomed to, we replicated the existing systems configuration using our Windows-based Gateway configuration editor. This not only facilitated a rapid install cycle, it enabled users to grasp the new system far more quickly... “We also worked very closely with ROH staff to
design, build and supply a combination of standard, ‘Touch’ desktop and custom- engineered operator panels for all parts of the main auditorium. For the main monitoring desk, which is only used for some performances, we supplied IP-connected Touch desktop panels, which combine enhanced functionality with easy readability.”
