The
Pope Comes Home: John Paul II Returns To Poland

Reprinted from September/October '97 edition
Any
Papal visit has, until recently, been a rare occasion. But since
the ascension of Pope John Paul II to the Throne of St. Peter,
the Papacy has logged more air miles than all the previous popes
combined. (At least worldly ones, anyway.)
On
June 1, 1997, this most peripatetic of popes arrived on the most
recent of several pilgrimages he has made back to his homeland,
a ten-day visit that saw him appear and say Mass before nearly
3,000,000 people.
Increasing
Need
As
the Pope's audience has grown, so have his sound needs. The solutions
to John Paul II's audio requirements have, in a way, kept pace
with the other technological answers to a pro-active Pope who refuses
to remain tucked away in the Vatican. Video, of course, broadcasts
the Pope's visage where ever he goes, but to give the greatest
number of people access to seeing him in person, the famous Popemobile
-- an open Jeep-like carrier with a 360-degree bubbletop of bulletproof
glass --was devised.
On
the audio side, when the Pope returned to Poland this time, the
task of getting his message across aurally was given to Poznan-based,
Fotis Sound Ltd.(FSL). FSL, owned by audio industry veteran Fotis
Tzokas, was started in earnest a dozen years ago, but, according
to Tzokas, he had been working with small multi-component sound
rigs for eight years before that while Poland was still under communist
rule and independent commercial ventures were subject to considerable
government scrutiny.
But
those eight years allowed him to develop his own resources to deal
with the problems of sound reinforcement in a country without easy
access to western technology. Once the barriers fell in the late
1 980s, Tzokas quickly became the country's leading SR company
based not only on technology but also on technique.
At
the Crossroads
Speaking
through his associate and translator Peter Witkowski, Tzokas noted
that the Poznan appearance was a particularly difficult one, due
to the fact that the Pope was to appear in the town center at the
intersection of two main thoroughfares. The two boulevards were
wide, but with a crowd estimated at between 190,000 and 220,000
attendees, the tactical aspects would prove challenging.
"The
first problem we encountered was that the distances from the center,
where the Pope was going to say Mass, to the farthest reaches of
where people were standing were so great," Tzokas recalls. "Just
in placing the FOH console [a Midas 48-input, XL-200] we were in
danger of running out of cable.
The
center of Poznan has a large monument in it and it is surrounded
by large housing blocks and some open areas. We did have enough
cabling, of course, but it was tight because we had to run so much
of the cable around obstacles and place it in such a way as to
not have it trampled by the crowds." The solution was to use
dozens of small speakers placed on high risers and on eight variably
timed delay lines to supplement the main SR cluster above the main
altar in the intersection. The center cluster consisted of two
full-range JBL HLA 4897 systems plus one HLA 4895 sub cabinet per
side. (This, incidentally, was the first appearance of the new
JBL HLA system in Poland and its arrival was just in time, due
to a delay the components encountered at Polish customs.)
From
the Frontier, Just in Time
According
to Pawel Danikiewicz of POLSOUND, the JBL sales rep in Poland, "The
customs problems that we have to deal with here are such that we
actually have an entire department within our company to deal with
nothing but that," he says, only half-laughing. "The
HLA system did get out of customs just in time for this appearance."
Fifty
meters forward of the altar, four JBL SR Series 4732A cabinets
were arrayed, with a pair of JBL SR4719A cabinets split on either
side. Another 100m (328ft) downrange was the second HLA system,
with eight HLA 4897 enclosures and four HLA 4895 cabinets located
atop a pair of high towers. Altogether, 22 HLA enclosures were
utilized at this Papal appearance. Other, smaller speakers were
strategically located throughout the area. Powering these arrays
were 28 Crown K2 amplifiers, 20 Crest 8001 amps and 40 Crest 7001
amplifiers. Speaker control was handled by the JBL DSC-280 processor
on the main HLA system, with BSS FDS-388 Omnidrives controlling
the rest of the systems.
Delay
and Other Details
The
delays, which Tzokas says were key to getting the intelligibility,
were a combination of one Yamaha D2040, one YDG2030 plus two Dl
030 delay lines, and one Roland EQ E660, which permitted the crew
to enter the distances in meters and allow the onboard processing
to determine the correct delay settings. No equalization was used
on the sound system itself the only application of EQ came on the
delays, via seven Klark-Technik DN 360 EQs and a BSS FCS-960 Varicurve
system.
The
foldback system was relatively sparse, consisting of twelve DAS
ST-32 wedges and eight OHM boxes. "Monitoring was not a real
issue in this instance." says Tzokas. "The problem was
not volume on the altar area, but projection and articulation into
the crowds. It was a very complex setting and speaker placement,
delay times and cabling were all critical," Tzokas recalls. "But
we were lucky in that the weather was nice that day. No rain and
no strong winds which could have cause dispersion problems.
"The
only real problem - other than the long throw distances - was the
reflections coming off the buildings that surrounded the plaza.
The signal-delayed speaker locations took care of most of that;
however, it was inevitable there would be some reflected energy.
That, says Tzokas, is where the JBL HLA system proved worth the
effort it took to get it through customs. "The HLA system
was excellent and that more than compensated for any remaining
reflections that we encountered from the surrounding buildings."

Insights
Micing
Pope John Paul II was a relatively simple matter, and, it seems
this pope is a savvy one when it comes to his audio preferences.
According to Tzokas, the Pope specified that there be no wire-less
headset microphones used.
Instead,
the Papal microphone specifications included a Shure Beta 58 and
a Sennheiser 441. "The Vatican specified only dynamic microphones," says
Tzokas. "There was very little EQ on His Holiness; no major
boosts or cuts." Both at Poznan and at the city of Gorzow
Wielkopolski, the second location that Fotis Sound did the Pope's
SR, choirs and bands were present near the altars. The smaller
but more professional choir at Poznan was mic'd with eight Shoeps
microphones and the orchestra with a combination of Shure Beta
58 and Sennheiser 441 microphones. At Gorzow Wielkopolski, the
larger 200-voice-choir and its supporting band of acoustic guitars,
bass, percussion and keyboards was mic'd with eight AKG C451s (with
CK-5 capsules) and Shure SM 57s and SM 58s.
Once
the signals came to the Midas FON console, a stereo submix was
tapped off and sent to a Polish National Radio remote truck.
The
Pope on the Pitch
The
appearance at the city of Gorzow Wielkopolski was simpler than
the Poznan venue - a large flat landscape made up of four soccer
fields in the center of the town, which could easily hold the crowd
estimated at 450,000.That Fotis had a longest cable run of two
kilometers gives an idea of the scale of this appearance. However,
the apartment building blocks that surrounded these fields resulted
in a degree of long-delay reflections. Again, the use of multiple
JBL speakers - this time including JBL M350 speakers - to support
the main JBL HLA cluster were used, although the small speaker
placement was more highly dispersed, says Tzokas, to cover what
was a 3000 range of attendees. Only the direct rear of the altar
had no viewers. And the amplification was higher than in Poznan
to deal with the larger crowd and larger space," he adds,
estimating the total wattage in Gorzow Wielkopolski at approximately
80kW.
