BOSE Professional’s ShowMatch with next-generation DeltaQ technology advances sound reinforcement in India
The rental market in India has evolved through leaps and bounds, nurturing qualitative growth
as its foundation along its path. And vital to this growth is technology; enhancements in
loudspeaker and line array systems being key. Today, the market has access to a plethora of
line arrays and loudspeaker systems promising quality, adaptability, portability and
efficiency in different coalescence. Users, however, do stress that there’s a lot left
to be desired.
Bose Professional presented its revolutionary ShowMatch array speaker system with the
next-gen DeltaQ technology to India’s pro audio community at the end of 2016; and ever
since has drawn attention of several rental companies and DJs across the country. Bose
Professional asserts that the Indian market is important to the brand as a key business
region, owing to its healthy growth rate and the potential for increase in the number of
live music venues, stadia, live theatres, and arenas in the years to come.
“With enhancement in infrastructure presenting a steady stream of opportunities, and live
event professionals emphasizing more on sound to create an enchanting experience for
audiences; the market in India was ready for the next wave of pro audio technology. As
a brand, Bose Professional has always challenged conventional approaches to sound, and we
believe the ShowMatch DeltaQ is the next-generation in revolutionary array technology
that’s been designed to answer the yet unmet customer needs in live sound. The ShowMatch
system provides users with the ability to design a system with consistent tonal balance
and significantly more detailed and balanced sound with uniform coverage; which makes it
easier to EQ and provide unmatched sound clarity” said Vibhor Khanna, Country
Manager – SAARC, Bose Professional.
The Bose Professional ShowMatch DeltaQ system has made quite an impression among key
players in the market; with reputed rental companies like Bangalore based Acoustic
Control and Hyderabad based Highbrow Production Services acquiring comprehensive
ShowMatch DeltaQ array rigs (complete with amplification + processing) as their
premier reinforcement solution. Teams from the respective rental companies proudly
expressed their elation with their new rig, asserting that the ShowMatch DeltaQ system’s
performance has far surpassed all expectations.
Sanjay Mudartha of Acoustic Control shares his comment on their new Bose ShowMatch system
saying, “This system is pure genius. Impressive is an understatement. From the thundering
bass to the clear mids and sparkling highs. This system delivers it all. Whether you’re
doing a gig that plays high-energy alt rock with a lot of slam-to-the-wall stuff, or
something mellow and calm like an acoustic set; the system is built to intersperse sound
cleanly, with great detail and amazing intelligibility. Plus, even if you have a mix with
a lot of dynamics, you’ll notice that the system retains all the power without fatiguing,
and with no issues translating the nuances of that FOH sound. And of course, the best part
about the system is its interchangeable horizontal waveguide plates which can easily be
swapped on site to suit any venue be it a small space or a performing arts center or
amphitheater or whatever. Plus, designing the perfect delivery system tailored to the
venue is an absolute breeze with the software. This is why the Bose ShowMatch DeltaQ is
next-gen; and we are absolutely proud to have it feature in our inventory.”
The ShowMatch array loudspeakers comprise compact Baltic birch ply enclosures, with weights
ranging from 64 to 67.5 pounds (depending on model), including the integrated 3-point
quick-pin rigging and endcaps. The array modules are offered in three versions
with 5/10/20-degree vertical dispersion; and under the protective steel grill,
two dual long-excursion 8-inch neodymium woofers flank a CADS (Continuous-Arc
Diffraction-Slot) manifold. The latter is a proprietary Bose innovation that provides
interference-free acoustic summation of the four Bose EMB2S compression drivers. The array
loudspeakers have also been recorded to deliver the highest full-range output for their size
class with 145 dB peak array output levels. And with field-changeable waveguides aimed at
optimizing sound quality throughout the audience area, users can create both traditional
J-Array, Constant Curvature and DeltaQ array configurations, bringing selectable coverage
control to the portable/rental markets. All the speakers are unpowered and employ two-way
designs with no midrange-specific driver; the crossover point is 1,500 Hz, sidestepping
the critical vocal range.
‘There are two key elements of differentiation for ShowMatch DeltaQ: Sound quality and
flexibility” explains Vibhor as he talks about the performance value derived from the
ShowMatch system. He continues, “With respect to sound quality, it is the vocal clarity
that the product provides. Historically, many loudspeakers have a crossover in the vocal
region, which degrades vocal clarity. We came up with a two-way system and invented new
proprietary transducers and compression drivers that kept the cross-over point outside
the vocal clarity range thereby improving the intensity and clarity of vocal projection
significantly. Another key positive of the ShowMatch system is its ability to deliver
seamless coverage throughout the audience listening area and achieve a system that performs
best to the venue orientation. DeltaQ refers to being able to vary or change ‘Delta’ the
directivity ‘Q’ of the boxes, both horizontally and vertically. This proprietary approach
enables the creation of a custom array shape to meet the needs of the venue. ShowMatch
modules have three different variants for the vertical coverage angles – 5-degrees,
10-degrees, and 20-degrees – and there are three different options for the horizontal
patterns which are field-changeable. The CADS manifold not only allows building arrays
made up of multiple modules, creating a smooth and coherent wavefront from the top to
the bottom of the array, but it also lets us bend the vertical, to create differing
verticals, while maintaining that acoustic spacing for coherent summation. So if you
want to change the horizontal coverage angles in the field, you are able to do so quite
easily. And you can even outfit modules for asymmetric patterns. This is something unique
to the Bose Professional ShowMatch DeltaQ system.”
Bose Professional asserts that the ShowMatch system has been designed to provide optimum
performance value when paired with amplification and processing products from the brand’s
portfolio. Vibhor elaborates “The ShowMatch DeltaQ array system powered by Bose PowerMatch
amplifiers and routed through Dante audio networking from Bose ControlSpace processors forms
the finest reinforcement system in its class available in the market today; and we are happy
to present the ShowMatch DeltaQ as a premium solution to rental companies and DJs who emphasize
world-class quality. We see great scope for it in the market here, and are confident of
exciting developments in the near future.”
