| Jones Audio Solves An Age Old Spoken-Word Audio Problem In All Saint’s Chapel / University of the South |
|
SEWANEE, TN—Known as “The
University of the South,” Sewanee
is a small,
quaint college with a serene campus located
in Sewanee, TN. At the heart is the
beautiful All Saints’ Chapel. As wonderful
and pristine as the chapel is, it’s also
very difficult to get audio under control.
While the large organ sounds brilliant in
the large space, accented by a deep reverb
that adds an enormous amount of depth and
majesty to the music, spoken word was a
different story, According
to installer
Ron Jones of Manhattan, KS-based
Ron Jones Audio,
it’s at times almost impossible to
understand someone speaking as close as 30
feet away. “It’s a very reverberant space
with a lot of stone and hard surfaces,”
Jones said. “There isn’t a lot of diffusion
or absorption. That audio just continues for
several seconds as it has an average RT60 of
6.5 seconds.” After working with Sewanee for
many years, he was finally tasked with
resolving the speech issues within the
facility. “The mission was to produce speech
clarity throughout all seating areas in
their various configurations with minimal
aesthetic impact, “ Jones explained. “This
required a highly directional loudspeaker
system that blends into the stonework as
much as possible. Also, we had to be very
specific about loudspeaker zoning, so that
unoccupied areas aren’t being filled with
reinforced audio.”
Jones specified and installed 21 of SLS Audio’s LS 6593V2 loudspeakers. “Anyone who knows SLS Audio knows that their claim to fame is their smooth-sounding ribbon tweeters,” Jones continued. “When these units are stacked vertically, you achieve precise control in the vertical plane, which means you can be very meticulous about coverage, keeping unwanted reinforced audio off the offending surfaces. “ Jones used eight stacks placed strategically around the venue and made sure that all of the seating areas were in the direct field, with no one left sitting in a reverberant field. Another key to achieving this result was DSP. Jones chose Lectrosonics’ ASPEN SPN1624 so that he could control all of the zoned loudspeakers independently, creating coverage only in the seating areas that are occupied. “I love the ASPEN as it allows me the flexibility to control this system in a way that’s easy to operate both with manual and automatic microphone mixing,” Jones said. “It has 16 inputs and 24 outputs, along with multiple configuration presets that are extremely helpful to the end-user. Basically, I set it up in a way that, with the touch of a button, allows reinforced audio to cover only the seating areas that are occupied, which significantly helps with speech clarity.”
In addition to his loudspeakers and DSP, he had several other pieces of gear that allowed him to achieve his desired result. Specifically, he went with QSC CX-series amplifiers, Yamaha LS9-16 digital audio console, Galaxy Microspots, and SurgeX power control. After careful planning and execution, in the end Jones was able to get everything right where he wanted, and delivered a sound so precise and accurate, that it was finally able to keep up with the stunning visual experience that All Saints’ Chapel provides.
