Pope Benedict XVI Papal Mass ~ Nationals Stadium ~ Washington, DC

Washington, DC 4/17/08 - As the first non-Baseball event for the new Nationals Stadium, the Papal Mass presented an interesting set of challenges for us. 
Tricked out with 450 EAW MK Series loudspeakers, a massive $250,000 Crown Audio amplifier stack, and an all-digital Yamaha-based mixing system, Washington, D.C.'s new 41,888-seat Nationals Park is one of Major League Baseball's premiere ballparks when it comes to audio support.  But even sports venues with the latest and greatest technology face challenges when they attempt to program non-sports-related activities.
Indeed, when Pope Benedict XVI scheduled a mass at Nationals Park on April 17, the event's producers had an acoustical challenge on their hands that would vex any ballpark, no matter how good the sound system.

The mass was configured with the stage fixed close and parallel to the centerfield wall, facing out to an outfield that would seat hundreds of the 47,000 who would attend the event, not to mention a choir and other interested parties. If the stage had been positioned in the middle of the field, say between second and third base, the angle of the native EAW loudspeakers rimming the perimeter of the venue would have been just fine—there wouldn't have been a delay problem for those situated on the field, because they'd be positioned virtually equidistant to all the speakers. But since the stage for the mass was at one end, it would have been impossible to time-align the native audio system to the stage.

Ultimately, MHA designed a scheme built around two 60-foot steel towers flanking the stage. The total speaker array included 32 Martin Audio W8L Longbow Line-Array speakers, 16 either side of the massive stage, 30 Martin W8LC speakers, 6 Martin WSX subwoofers, and 2 Martin WT3 enclosures.  
MHA Audio worked closely with Martin Audio UK to acoustically map the venue in the company's own Display predictive software in order to determine the optimal angles for the line-array speakers, which had a 550-foot throw to the farthest seat.

The Mass wasn’t just about clear spoken word reproduction, because on stage right, behind the speaker tower a 700-member choir and an orchestra of 50 performed throughout. Entertainment included notable opera singers Placido Domingo and Denyce Graves who performed prior to the mass. 

The MHA crew consisted of Mike Scarfe assisted by Robert Bowers/System Techs, Zane Marshall assisted by Peter Maher at FOH;  David Colella assisted by Tom Buckley, Monitors on the Orchestral Stage and Gavin Pearce, assisted by Bruce Coffman, Monitors on the Entertainment Stage.  Additional crew were:  Bruce Nelms, Keith Suffecool and Mike Moats. 

Our client, Showcall Inc, an event company specializing in large, high threat events, was thrilled with the results. The representative from Vatican Radio, Roberto Calcigioni, was very enthusiastic stating that his prior use of Martin Audio in Europe had always been a positive experience.

Air Force Memorial Dedication~ October 2006

Arlington, VA––Appropriately enough, the new Air Force Memorial is marked by three arched stainless steel spires that soar 270 feet in the sky with a commanding view of the Pentagon, the Potomac River and the Washington, D.C. area.

Designed to evoke the Air Force's Flying Thunderbirds' "bomb burst" maneuver, the memorial is counterbalanced by a 10' x 9' contemplation wall made of fine layers of glass and engraved with Air Force planes performing the "missing man" formation. Fifty-six foot long black granite inscription walls at each end of the central lawn complete the monument.

The dedication ceremonies literally happened on two levels. At the memorial site, there was an open-air event attended by over 1,500 military VIPs, government dignitaries and distinguished guests who had raised money for the memorial. Highlights included thunderous flyovers, speeches by President Bush, Defense Secretary Rumsfeld and others along with music by the Air Force Concert Band & The Singing Sergeants.

Down below, the Pentagon’s South Parking Lot, accommodated an additional overflow of 40,000 guests with a display of jets and helicopters and a 50' stage for a concert featuring the Air Force Band's R&B/rap/hip-hop/funk contemporary offshoot, Max Impact, and country artist, Lee Ann Womack. All of the additional guests in the South lot and another overflow site with 7,500 more guests were able to view the ceremonies in real time via a live Satellite feed.

At the Memorial MHA AUDIO set up two stages, one on the left side of the Memorial for speakers and dignitaries, and one on the right for the Air Force Band, which was totally self-contained with a Digico D5, a complete Neumann mic package and their own technicians.

We hung six Martin Audio W8LC's on two ALC S-60 towers and situated them far left and far right for as low a profile as possible and then used two Martin W8C's stage left of one stage and two stage right of the other to bring the focus into the middle.

The rest of the audio system at the memorial ceremonies included a Midas Venice 320 console, two Klark Teknik DN360 EQ's, a BSS DPR402 comp/limiter and a Klark Teknik DN410 Parametric EQ. The system was driven by XTA DP226 processors and Martin Audio MA 4.2 amplifiers.

Down at the South Parking lot, the stage system consisted of 10 Martin Audio W8L’s and 6 WLS subs a side, along with a Midas Venice 320, 8-channel TC EQ Station, two BSS DPR402 comp/limiters and a Klark Teknik DN410 Parametric EQ. Lee Ann Womack and Max Impact provided their own FOH and monitor package.

In addition we flew 48 Martin W8LC's on two delay rings to provide coverage for 40,000 people in an area over nine hundred feet deep. Each of the two arcs, positioned 300 ft. and 600 ft. from the stage included four towers of six W8LC. The signal was distributed via a Lectrosonics UHF system.

When asked about the Air Forces reaction, our client Kim Frame, working for Showcall, Inc. concludes, "Air Force Major General, Edward F. Grillo, was very excited and thrilled with the event."
