Historic Costa Rican Theatre Undergoes A Modern Sonic Transformation

Further, the Metrix cabinets were outfitted with Enclosed Installation Rigging (EIR) system, providing all of the flying/aiming precision and safe structural support found in the rigging for touring Metrix enclosures, but at a lower cost.

Four Metrix Sub compact subwoofers, each with dual 15-inch Kevlar neodymium mid-low frequency woofers, can be utilized to extend low-frequency response for applications requiring it.

These can be rolled out to the wings of the stage via dollies or placed under the stage on the main floor level, with cabling infrastructure facilitating quick connection at both locations.

Several Adamson CB1 compact 2-way loudspeakers providing 90-degree by 60-degree dispersion are mounted horizontally in cutouts on the face of the stage to supply front fill support.

Additional CB1 loudspeakers are flown singly, using the supplied mounting hardware, at the far sides of the proscenium to bolster presence in the boxes and gallery seating located nearer to the stage.

All of these loudspeakers are carefully time-delayed in reference to the main arrays to insure synchronous arrival.

A Higher Level
Just two Adamson M Series 4-input by 8-output digital loudspeaker processors were required for all loudspeakers, providing all filtering, limiting and delay. One of these processors feeds the main arrays and subwoofers, while the other is applied to the front frill and side fill satellite loudspeakers.

Adamson Shooter helped optimize the design. Here we see a top-view prediction of coverage to orchestra seating, boxes and the back area (full range A-weighted).

Lab.gruppen power amplifiers, recommended by Adamson to drive these loudspeakers, are rack-mounted in a secured room with the digital processors. Two FP 10000Q power the arrays, with a single FP 7000 for all four subs and a C 28:4 offering four channels for the remaining fill loudspeakers.

The former system’s Midas Heritage 2000 mixing console was retained because it is still performing at a very high level and affords plenty of mix facilities for any application hosted at the theatre.

The console resides on a cart so it can be easily rolled into position when needed, with infrastructure for quick interconnection built into the main floor mix position. It is also capable of serving as the monitor console when small wedges from the existing system are needed.

The RTS team performed the new system installation quickly and efficiently during a “dark” period for the theatre, and it debuted to positive reviews that have not ceased. “The new system has exceeded all the expectations, offering the coverage, sound quality, and aesthetic ‘look’ the client was seeking,” Fernandez concludes.
