USA - Located at the Oconto Falls High School in Wisconsin, an ageing sound system in the Falls Area Performing Arts Centre (PAC) has been replaced with Martin Audio’s new scalable resolution Wavefront Precision Mini (WPM) line array. Part of a complete AV upgrade to the technical infrastructure, the work was carried out by Camera Corner Connecting Point in Green Bay, Wisconsin, following a competitive bidding process.
According to their project designer, Steve Littlepage, the contract was broken into two phases: a complete video upgrade, followed by the installation of the PA and system processing, as well as supply (and relocation) of a new digital mixing console.
The function of the PA was to provide an even coverage for a seated audience of up to 700, and be sufficiently versatile to serve not only a range of school events, but incoming productions hosted through a community foundation, for which the school has a long history.
Camera Corner was given carte blanche by the client to design a system “that would solve their issues and help the venue be a technology leader in the area.” After careful consideration, their PA of choice was the WPM—their first Martin Audio line array deployment.
“We considered a variety of manufacturers, focusing on line array solutions for the venue, but the WPM had exactly the right coverage to price ratio for the project,” Littlepage continued. “Using an array allowed reduction of the level variance from the front to back of the audience—unlike the point source solutions we considered—and the wide horizontal pattern allowed consistent coverage left to right across the venue.”
The designer was also aware that the locations for where they could place new loudspeakers were limited, and this additionally created weight restrictions. Camera Corner’s solution was to hang the arrays from the building truss—between the proscenium opening and the first ceiling cloud. “The compact size of the WPM allowed us to do this while still minimising the impact this location had on the lighting system.”
Through a combination of the Martin Audio Display optimisation software and EASE modelling of the arrays, Camera Corner was able to illustrate the coverage of the system during the design phase and explain the advantages of this system to the school officials.
“Attention was given to reduce the amount of stage wash coming from the arrays as well as slapback off the rear wall. It was important to improve the gain before feedback of the system as the school theatre performances are regularly run by student operators.”
The design comprised five Martin Audio WPM elements per side, with one SXF115 subwoofer flown above each array. Two SX218 subwoofers sit at the proscenium opening to round out the bottom end for more audio intensive events, while four Blackline X8 speakers serve as lip fills across the front of the stage. The arrays are permanently hung, and the ground subwoofers and lip fills can be moved when necessary for a particular event or when not in use.
To further optimise this, the main PA system is powered by Martin Audio iKON amplifiers -one iK81 assigned to each array, in single-box resolution. An iK42 has been deployed for the SX218 subwoofers, with two channels per cabinet. Spare channels of the iK81 amplifiers, not being used for the arrays, are used to drive the Blackline X8 lip fills.
At the same time Camera Corner replaced the entire video system, and added Crestron control for the audio and video system. They incorporated two operating modes for the system, a ‘Performance’ mode for theatre, and ‘Presentation’ mode, for simple lecture style presentations.
Following the installation Camera Corner provided full operator training for the key personnel and assisted with the first event for the new system, which Steve Littlepage says “went fantastically”. Managing the project was Tony Stahl, and account manager was Chris Lecher.
