Vance Breshears was part of the team that implemented one of the first computer-based audio processing and routing systems at the Opryland Hotel and Convention Center. |
There are certain projects that stand out,
and for Vance Breshears, the Opryland
Hotel and Convention Center was one
of them.
Nashville is not just any town, and as
such, Opryland is not just any meeting
place. And so, back in the mid-’90s when
Gaylord Entertainment Group, the hotel’s
management, embarked on the fourth
phase of an expansion project, it mandated
technology that was, well, not just any
technology. As part of this phase, the hotel—
which at the time comprised 4,000 rooms
and one million square feet of conference
and exhibit space—was constructing a large,
900-seat ballroom that could be divided into
four smaller spaces, as well as a four-and-ahalf-
acre glass-enclosed atrium called The
Delta. Breshears, then in the early years of
his relationship with the Dallas-based design
firm Acoustic Dimensions (where he is now
a director), along with his colleague Craig
Janssen (the firm’s managing director) was
charged with designing a technical system that
delivered computer-based audio processing
and control, and that was easy to operate by
a single person, or via wall-mounted, remote
control interface panels.
Enter Peavey MediaMatrix, which was in
the process of revolutionizing computerbased
audio processing and routing.
“These systems were really the first of a
new generation of systems that could do
a lot of different things,” Breshears said.
“MediaMatrix could be operated in all of
the rooms in any kind of configuration.”
The firm also specified Crest CKS and CKV
Series computer-controlled amplifiers. “We
wanted to be able to do impedance sweeps
of the amplifiers to make sure that they
were working correctly. Because we had
the ability to do impedance sweeps, it was
actually pretty easy to troubleshoot some of
the installation problems that cropped up.
We didn’t have to bring in a bunch of extra
test equipment—it was right there as part of
the system and we could troubleshoot things
rapidly and solve a lot of the problems.” A
Crestron control system was specified to
manage the MediaMatrix systems and enable
the adjustment of input and output levels in
each of the spaces.
What made this project so special was the
level of flexibility the technology offered. “It
was the first completely open architecture
DSP system you could get into and program,
and make the system whatever you wanted it
to be,” Breshears said. “You weren’t limited
by specific hardware boxes; you were able
to use software-based modules inside of
MediaMatrix that would represent hardware
boxes.” The system, he added, could be
anything you wanted it to be.
“The MediaMatrix was really the result
of the hotel leadership’s desire for very
comprehensive control systems,” Janssen
said. “Prior to that time, we really had
discrete systems control, so each element
of a system, each space—be it a ballroom
or a restaurant, or so forth—was either via
individual systems control, space by space,
or it would be an analog integrated system.”
This was complicated when it came to both
set-up and control, he added, and was often
inflexible and inconsistent. “The promise of
going completely digital was very exciting.”
Robert Rose, now vice president at Acoustic
Dimensions, was project engineer for Ford
Audio-Video Systems—the Oklahoma Citybased
systems contracting firm charged with
integrating the system—at the time. He noted
that it was his first experience with a DSP
system that, as he put it, appeared to have
very few restrictions. “You needed to get all
the inputs and outputs wired, but after that
it was all software programming,” he relayed.
“There were very few limitations, and infinite
possibilities.” He added that this is not to
minimize the degree of physical installation it
required—which involved hundreds of inputs
and outputs—but he says that software
programming took center stage. “This has now
become more of the norm, but remember up
until that point you had to use a large number
of analog or basic fixed digital devices and had
to completely map out all of the routing and
functional options.”
For Breshears, it was for this reason and
others that Opryland remains a memorable
project. “It was a risky project, and we were
doing something new and different,” he said.
“And because of that, you run the risk of having
some challenges and some growing pains. We
certainly had that with this project. But it’s
one of those that sets a precedent for future
projects. It definitely did that for us.”
