EVERGREEN MLA PRESENTS GILBERTO GIL WITH MEMORABLE FAREWELL TOUR EXPERIENCE

After a career spanning over six decades, Brazilian music legend Gilberto Gil is midway through a farewell tour titledTempo Rei.This is taking him through sports palaces and stadiums in nine Brazilian cities—including the 42,000-cap Ligga Arena in Curitiba and the Farmasi Arena in Rio di Janeiro—and is scheduled to run until November.

At all but one of the shows he has been playing through an evergreen Martin Audio MLA loudspeaker array, provided by partner Gabisom Audio Equipment.

Responsible for the sound system design, optimisation and recording is Martin Audio devotee, the eight times Latin Grammy award-winning Daniel Carvalho, who has regularly mixed through MLA—a popular presence in Brazil since it first appeared at the famousRock In Riofestival.

“Farmasi Arena [aka the Jeunesse] is not an easy venue,” he admits. “It has a long reverb on the low end and the shows there are known for delivering a muddy sound. But with the low leakage of MLA, side lobe reverberation is much lower in volume and the clarity of the vocal penetrates the field comfortably with the electronic processing. With normal systems, production uses a delay for upper balcony but with the long throw of the MLA system we were able to do without.”

“IT’S AN AMAZING FEATURE THAT MAKES MLA GAME CHANGING,”

Daniel Carvalho, FOH

The PA comprised 17 MLA and an MLD per side, and 17 outfills (also with a single MLD). A castellated subwoofer array of 34 MLX speakers and eight MLA Compact front fills completed the set-up. “Many musicians and producers commented that it was the best sound they had ever heard in the house,” noted Carvalho. “We certainly had no complaints.” This despite being unable to fly the subwoofers due to loading restrictions, as they have been doing in other venues.

Most of the array optimisation was prefigured in Martin Audio’s DISPLAY software. “I use the DISPLAY 3 (with WPL in place of MLA) to gain some insight of the horizontal coverage and azimuth of the arrays. In places, it just required some minor EQ and level in the delayed arrays to align with the main PA. I could then walk around with the venue software and Smaart computer and tune it all.”

The ’Hard Avoid’ feature was deployed to great effect. “It’s an amazing feature that makes MLA game changing,” he says. “It’s more than a cardioid in the way it keeps sound off the stage. With the PA at full volume Gil asked during sound check: ‘Is the PA really on?’ The volume before feedback we can get, together with the castellated subs makes the stage clean and the musicians comfortable. As Brazilian MPB (Brazilian popular music) songs are noted for having very quiet moments, the Hard Avoid feature makes everything possible in large venues.”

Gilberto was supported by an exceptional backing band including many of the Gilberto family (sons, grandsons, daughter and extended family)—with a string quartet and horn section. He also introduced some surprise guests at the Farmasi, like Caetano Veloso, Anitta, Marisa Monte and lulu Santos.

The shows here extended over four days, with 17,000 people witnessing the legend each night. Describing the experience, Daniel Carvalho, said, “From the very first moment it was clear to all that the sound was at another level.

“Gil is 83 years old, and his voice came through loud and clear on top of a big band with a lot of percussion, horns and guitars. All Brazil’s greatest artists respect Gil and came to the show—many commenting on how impressed they were with the sound; they could hear everything clearly to the point that it sounded like a CD.

“Gustavo Mendes, Gil`s FOH sound engineer, was so impressed [with MLA] that he shared the same concerns as I: ‘How can we do a show without this system’? Each time we walk the venue to listen, it is so impressive the way it sounds the same at each seat. Maths really is like magic.”

And his final word? “This system was so far ahead of its time that nowadays we see other brands trying to do what MLA was doing an incredible 15 years ago.”

The nine-strong product range comprises improved passive two-way point source loudspeakers, all-new column speakers and a suite of subwoofers. The entire series features intelligent design details, making it equally at home in portable or install applications, such as portable sound reinforcement for live sound, theatre, DJs and corporate events; unobtrusive stage monitoring; and permanent installation in clubs, hospitality venues, conference rooms and houses of worship.

In sync with Martin Audio’s design philosophy, BlacklineQ extolls the virtue of meticulous driver design to deliver improved coverage, consistency and control. For the first time in its class, both full-range two-way point source systems and column speakers feature Differential Dispersion horns, which enable wider, more consistent coverage with less energy directed to the ceiling.

“BLACKLINEQ IS OUR MOST AMBITIOUS SERIES IN BLACKLINE’S STORIED HISTORY, AND WITH THE INTRODUCTION OF BOTH DIFFERENTIAL DISPERSION TECHNOLOGY AND COLUMN SPEAKERS IT’S DESTINED TO BE OUR MOST SUCCESSFUL.”

Dom Harter, Managing Director

For the four point source speakers (designated Q8, Q10, Q12 and Q15), each symmetrical, multi-angle full-range passive wooden enclosure can be easily deployed in horizontal or vertical deployment, with comprehensive mounting options—including wall brackets, yokes, eyebolt suspension and pole-mounts. A pole-mount cover provides a clean, streamlined appearance when the mount is not in use.

BlacklineQ also marks Martin Audio’s debut in column speaker design with the two-way passive QC44 and QC26 offering elegant, discreet solutions for both portable and fixed use, and perfectly suited to speech and musical content. Finished with hard wearing black or white paint, and complemented by comprehensive mounting options, these new column speakers will substantially increase the available applications on offer to the Martin Audio line-up.

Finally, BlacklineQ includes a trio of passive subwoofers, comprising the Q210 (2×10”), Q118 (1×18”) and Q218 (2×18”), which extend low-frequency performance across the series. The enclosures are constructed from durable plywood and feature slot ports for efficiency in design while reducing noise turbulence. Each enclosure includes an M20 35mm (1.4”) pole-mount fitting for seamless integration with all loudspeakers in the series. In addition, the link out socket is positioned at the top of the cabinet, providing a convenient and discreet solution for connecting the cable for a BlacklineQ loudspeaker on a pole. Finished in hard wearing black paint as standard, the Q210 is also available in white to match the white BlacklineQ column loudspeakers.

Dom Harter, Managing Director, commented, “BlacklineQ is our most ambitious series in Blackline’s storied history, and with the introduction of both Differential Dispersion technology and column speakers it’s destined to be our most successful.”

BlacklineQ will start shipping from late August and will be first shown and heard at InfoComm Asia on Generation AV booth C05.

Martin Audio deployed for Osaka’s Expo Arena Matsuri

JAPAN: The Expo Arena Matsuri outdoor venue at the Osaka Expo has been outfitted with Martin Audio sound systems, provided by Audiobrains and System Engineering. Serving as the largest outdoor hub at the Osaka site, the outdoor location has capacity for approximately 16,000 people and is hosting a variety of events, including international music shows, Yosakoi festivals and traditional Bon Odori dance performances.

System Engineering was responsible for designing and installing the system. Mr Goto, a member of the company’s sales team, said they had heard Martin Audio during various listening sessions, building trust with the brand. “For this expo, we needed to place importance on cost in addition to sound quality and performance, so we chose Martin Audio as our candidate because of its cost benefits,” he explained. “The acoustic simulation was also provided to us very quickly for when we proposed the system to the Expo Association.”

WPL-PU units from the Wavefront Precision line array (WPL) series serve as the main PA system for the vast arena space. These are complemented in the lower frequencies by 20 SXH218 subwoofers installed under the stage, with WPS-B-MAR cabinets deployed onstage for in fill. Side fills are covered by WPS-B-MAR units combined with SXCF118 cabinets installed on the wings of the stage. Monitoring is courtesy of XE300 loudspeakers and FP8 boxes for the FOH monitor. All speakers are powered by the iK42 DSP-equipped amplifier.

L–R: Mr Kawachi, Mr Goto and Mr Hashimoto of System Engineering

According to Mr Kawachi of System Engineering, the original sound design was based on the premise that the structure would be temporary, however, as the arena will be used for a variety of events, the system needed to be able to operate without trouble for six months. “We had to redraw the drawings and work hard to create a system that balanced the temporary and permanent aspects,” he noted.

As the installation is outdoors, a key challenge was trying to prevent the loudspeakers from shaking. “The venue is close to the sea and can face strong winds of up to 10m per second,” noted System Engineering’s Mr Hashimoto who managed the construction of the setup. “In the end, by making good use of the flying metal fittings and the speaker handles, we were able to create a sturdy anti-sway system that would not budge even in strong winds.”

Hashimoto cited the positive aspects of using the Martin Audio system: “In terms of functionality, the ability to finely adjust the directivity is a big plus – the sound really disappears from the area where the attenuation is set. Even though it is such a large-scale system, there were no major problems and after the opening ceremony, we received feedback that the sound was great. We are honoured to have Martin Audio selected for such an international exhibition and will provide full support until the end of the event.”

TORUS HELPS VIETNAM’S POC POC GARDEN REMAIN IN DJ MAG’S TOP 100 CLUBS

Vietnam: For dance venues the world over, one of the most coveted accolades is recognition in the prestigious DJ Magazine Top 100 clubs.

Located in the Vietnam capital of Ho Chi Minh City, POC POC Garden first featured in the list the year after Duc Pro Audio fitted a premium Martin Audio sound system, back in March 2023. Now in 2025 it has risen even higher in the rankings of the world’s most important nightclubs.

Located in the heart of District 3, and with an impressive outdoor space and premium stage, the club combines unique artistic performance with high octane dance music.

Faced with a fierce competitive tender against another leading speaker brand, Duc Pro Audio extended its long association with Martin Audio by drawing on the brand’s matchless nightclub pedigree. It has enjoyed consistent presence in superclubs ranging from Ministry of Sound to fabric—the latter recently upgraded with next generation Martin Audio sound.

“AS THE HEIGHT OF THE GLASS INTERIOR IS APPROXIMATELY 8.5 METRES AND THE CAPACITY AROUND 1,100, WE KNEW TORUS WOULD DELIVER EXTREMELY HIGH-QUALITY AUDIO,”

Mr. Chien, Owner, POC POC

Duc Pro Audio product manager, Pham Duy Quang, never had any doubts that a TORUS constant curvature system would provide the definitive solution for this venue, and its owner, Mr. Chien.

“As the height of the glass interior is approximately 8.5 metres and the capacity around 1,100, we knew TORUS would deliver extremely high-quality audio,” he declared. “The speakers produce a clean sound and combine extremely well with the powerful SXCF118 subwoofer.”

The sound also had to satisfy its many incoming high profile production teams from around the world, since POC POC hosts a wide range of events—from art performances to some of the most highly renowned EDM names in the region, as well as competitive rap events. “The club also welcomes dance crews from Cuba, and has a giant water tank with daily mermaid performances and many other spectacular visuals that make use of a huge ceiling hoist system. TORUS handles it all effortlessly, and delivers an impressive performance,” says Mr. Quang.

Inspired audio design was critical to this success. Duc Pro Audio have arranged the main PA in four flown columns, hanging above the stage and DJ booth—single L/R columns flanking a centre hang of two. This centre array is made up of three T1215 and a pair of SXCF118 subs, whilethe outhangs comprise three T1215. A further four columns are suspended in front of the stage over the audience, and delayed—each comprising a pair of T1215 and a single T1230.

For front fill, eight further T1215 are placed along the front of the stage facing the audience, while the all-important sub frequency rumble is extended via eight Martin Audio SXH218, set under the stage front.

Mr. Chien is a well-known investor in Ho Chi Minh City’s nightlife, and he expressed unqualified satisfaction with TORUS. “As such, he will continue to trust Duc Pro Audio and Martin Audio in future projects,” states Pham Duy Quang confidently.

Added Martin Audio marketing director, James King, “We are proud once again to have key representation in DJ Magazine’s list of globally famous dance venues. We have a long and distinguished heritage in equipping venues and global EDM events alike with our premium sound systems. We are grateful to our partners in Vietnam for their continued faith in our world-beating solutions.”

A Discerning Soundscape Enchants Dubai

Exacting Diseno Technical Services Relies on Martin Audio to Deliver A Premium Sonic Ambience at Dubai’s Coco Grill & Lounge

Exacting Diseno Technical Services, helmed by Lou Agha, continues to strengthen its reputation for high-quality installations in Dubai’s luxury hospitality sector with the deployment of a premium Martin Audio sound system at Coco Grill & Lounge. Developed in partnership with regional distributor PRO LAB, the installation supports a unique concept from venue owner Naz Choudhury — a fusion of upscale Shisha Lounge and Dubai’s first Redemption Bar, offering alcohol-free sophistication with an emphasis on immersive experiences.

Coco Grill & Lounge is the Dubai extension of Choudhury’s original concept in London, which overlooks Tower Bridge. The new downtown location offers similarly spectacular views — this time of the iconic Burj Khalifa — and continues the brand’s ethos of high-end hospitality paired with rich musical atmospheres. When asked about audio preferences, Choudhury was immediately drawn to Martin Audio, having used the brand in his London venue.

Agha began the project with a demonstration at PRO LAB, showcasing various Martin Audio options including CDD models and FlexPoint systems. “We started with the small FP, and he was amazed by the sound quality,” recalled Agha. This led to a customised system design tailored for the venue’s low ceilings, mixed-use layout and live performance requirements.

Agha began the project with a demonstration at PRO LAB, showcasing various Martin Audio options including CDD models and FlexPoint systems

The interior zones are served by Martin Audio CDD6 speakers, while the venue’s expansive outdoor areas — blending shisha service with DJ sets and live acoustic music — feature 14 units of the Blackline X8 loudspeakers supported by six SX112 subwoofers. The entire system is networked via a Dante backbone and spread across nine independent zones. The design also integrates six refurbished ADORN A55 speakers, supplemented by additional units at the venue’s entrance, where a pair of A55 and an SX110 subwoofer create a warm welcome.

As patrons pass through to the Dome area, they’re immersed in sound via six FlexPoint FP8 speakers and four SX112 subwoofers. Even the venue’s restrooms aren’t overlooked — ADORN ACS 40TS ultra-compact ceiling speakers deliver refined background music at 16 ohms, maintaining acoustic consistency throughout.

The non-smoking lounge areas feature dedicated soundscapes: one zone includes four CDD6 and two SX110 subwoofers, while another utilises six CDD6 with two SX110 units. The smoking areas are similarly equipped, ranging from two to four CDD6 units per section, supported by appropriately scaled SX110 subwoofers. One of these sections, Smoking Area 3, is also available for private rental, necessitating a discrete yet powerful setup of four CDD6 and two SX110 units.

The entire system is networked via a Dante backbone and spread across nine independent zones

“In order not to intrude on the lounge’s aesthetic, the subwoofers are placed discreetly,” noted Agha. “I used the SX110 rather than the SX210 because of space constraints — I couldn’t put the SX210 on its side, so I separated them into pairs of SX110s.”

By day, the venue operates with a curated Spotify playlist programmed by Coco’s DJs, with selections favouring Afro Beats to maintain a unified sonic identity across both the London and Dubai locations. Audio routing and DSP are handled by a Xilica FR1 processor, ensuring seamless zone control and sound shaping.

Describing itself as a venue that “redefines sophistication,” Coco delivers on that promise not only through its culinary and visual elements, but also through the detail and depth of its sound — made possible by a Martin Audio system meticulously tuned to elevate every facet of the guest experience.

PENGUIN REVAMPS LAINE PUB CO SOUND WITH MARTIN AUDIO

UK: Martin Audio partner, Penguin Media Solutions, recently completed the third technical overhaul of pubs in the burgeoning 50-plus Laine Pub Company estate—within a short period.

Both organisations are HQ’d in Brighton, and Penguin’s Technical Project Manager Dylan Thompson says that since all three city centre pubs have their own identity and autonomy an individual approach was required when it came to specifying audio. Fortunately, Martin Audio’s extensive portfolio afforded different options.

Penguin’s latest implementation was the Black Lion, a popular music pub nestled in Brighton’s famous Lanes. The client required better traffic flow to draw its clientele towards the rear of the room—where the intensity would increase—and avoid the current pinch point at the front. “The previous design was a bit lazy, with lots of mismatched 8in boxes scattered around and a sub that wasn’t doing much. It all sounded a bit samey and thin, and we were asked to give it personality.”

Placing both the acoustic and visual focus on the DJ, Penguin designed a new cast concrete booth, equipping the compact domain with a Blackline X12 as reference monitor and powerful SX215 subwoofer on anti-vibration mounts.

Either side are now a pair of Martin Audio FlexPoint FP12s and eight Blackline X8 for general room fill. Explaining his selection Thompson said, “I didn’t want to go much smaller than that because I wanted to keep a nice warm mid-bass running through and we didn’t have many options for sub placement. I really like the whole FlexPoint range, Martin Audio have absolutely smashed that one!”

“THS IS A PERFECT BOX FOR THIS APPLICATION”.

Dylan Thompson, Technical Project Manager, Penguin Media Solutions

To this he added a pair of Blackline of X210 subs—one flown to place it in the required location, and another under the banquette seating at the front—all driven by two sister brand Linea Research 88C10 amps. Sound is routed via an existing Soundweb venue matrix, with DSP handled within the Linea environment.

Another of Martin Audio’s sister brands, Optimal Audio, comes into play outdoors where 16 Cuboid 3T (with IP kit) are installed—described by Dylan Thompson as “great little boxes.”

The entire venue is then controlled via Penguin’s bespoke app, developed in-house. “By using third party control with a web app—and not platform specific—the supervisor, manager and DJs can control the lighting. There is a little tablet in the booth to trigger the presets, and levels and source for each zone can be controlled for on the same app.”

This was part of a larger project in which the integrators designed and installed pixel lighting—industrial looking tubes behind and above the DJ, with flush plastered profiles for the arches, and recessed profiles for wall washing.

Less than a year earlier Penguin Media Systems had carried out their first installation contract for Laine, after being recommended. This was The Hope & Ruin, described as a much-loved grassroots live music venue, known for championing new bands. Penguin’s recommendation was the super-powerful Martin THS 15in triaxial point source speaker, and pair of SX215 subwoofers now feature at the front of the stage … replacing an ageing system that had become unreliable. At the same time they provided the venue with four LE100 artist reference monitors.

“THS is a perfect box for this application,” believes Thompson. “Because it doesn’t take up much room visually, they now have better sightlines.”

Having passed their induction, Penguin were then offered the Dead Wax Social, another city centre. pub that’s a modern re-take on an audiophile’s dream. Here Dylan Thompson made the inspired decision to roam quirkily off grid, specifying a pair of Martin Audio Screen 4s, originally designed as a cinema system, in newly fabricated custom flying frames.

His rationale in recreating a 70’s listening bar theme was entirely logical, as he explained. “We played about with them and did a bit of voicing change to suit the creative brief and aesthetic from Rob Hall at Laine; we also turned them horizontally in their new frames to make them look even more eye-catching as well as gaining space.” He also painted the baffles, and in their new hammered green finish, the speakers have now become a visual focal point as well.

Laines Pub Co MD, Russ Danks was delighted with the recent upgrades and their impact with their young and vibrant guests. “Penguin’s choice of different Martin Audio sound systems has totally energised these pubs. At Laine we are driven by re-imagining our spaces for a younger generation, and all those that share the spirit and energy of youth, The content in our businesses, whether DJ led, vinyl, bands or drag artists, need to sound bloody good, and Dylan and the team at Penguin help us nail this every time.”

EXACTING DISENO UNITE MARTIN AUDIO FAMILY AT COCO DUBAI

UAE: Lou Agha’s system integration company, Exacting Diseno Technical Services, are fast gaining a reputation for installing premium Martin Audio sound systems in some of Dubai’s smartest upmarket bars and lounges.

Working closely with territorial distributors, PRO LAB they recently equipped Coco Grill & Lounge for owner Naz Choudhury, whose unique concept is to integrate a Shisha Lounge with Dubai’s first Redemption Bar. It follows the operator’s initial launch of the Coco brand in London, overlooking Tower Bridge—and offers the same breathtaking views from its downtown location, this time of the Burj Khalifa. All operations are alcohol-free, with upscale mocktail bars.

Lou Agha had been introduced to the project via a consultant. “When the client asked what sound systems I used, he was pleased it was Martin Audio, as this was the brand he was using in London.”

Agha first arranged a demo at PRO LAB of various CDDs (up to 8in) and FlexPoint. “We started with the small FP, and he was amazed by the sound quality.” He then quoted in various configurations, recommending CDD6 for the venue’s low-ceilinged interior and 14 punchy Blackline X8 for outdoors which combines Shisha Lounge with DJ and small combo live acoustic music, with vocalists, in a non-stop entertainment package.

The unit is divided into nine separate zones—all networked on a Dante backbone. The 14 Blackline X8 are complemented by six Martin Audio SX112, while six pre-existing ADORN A55 have been refurbished and added—four on one side two on the other.

At the entrance another pair of ADORN A55 and single SX110 sub beckon customers in, and as they enter the Dome, they are greeted by six FlexPoint FP8 speakers, with four SX112 subs.

“Inside the client wanted high quality music io be extended to the toilets,” continues Lou Agha, “so we have ADORN ACS 40TS ultra-compact ceiling speakers running at 16 ohms. That way they sound really nice.”

The lounge features two non-smoking areas: one contains four CDD6 and two SX110. While the other has six CDD6 and two SX110. In Smoking Area 1, are a further four CDD6 and two SX110; Smoking Area 2 has two further CDD6 and a single SX110, and Smoking Area 3—which can also be rented for private occupancy—is equipped with four CDD6 and two SX110.”

Lou Agha says that in order not to intrude on the general aesthetic of the lounge, the subwoofers are placed discreetly. “I used the SX110 rather than the SX210 because of space constraints,” he says. “For that reason I couldn’t put the SX210 on its side, so I separated them into pairs of the SX110.” By day the venue’s background music operates off a Spotify playlist, common to both London and Dubai—programmed by one of their DJs, with a theme heavily weighted towards the popular Afro Beats. Routing and DSP are under the management of a Xilica FR1.

On Coco’s website, the venue boasts that “from 24-hour upscale dining to theatrical culinary experiences and late-night lounging, Coco redefines sophistication.” And thanks to its sophisticated sound system, delivering a high-octane musical experience, it certainly lives up to this promise.

O-LINE EXCELS IN HISTORIC TASMANIAN CHURCH

Australia: Dating back to 1824, St. John’s Anglican church in Launceston, Tasmania is the oldest church in the city, having recently celebrated its 200th anniversary. To mark the bicentennial the church committee commissioned a major upgrade, largely to enhance speech intelligibility. GUZ BOX design + audio, headed by founder Tim Kuschel, were tasked with overseeing the acoustic and electroacoustic design works.

This was back in 2020, but hampered by COVID restrictions and a lack of data, it wasn’t until March 2021, in the post-COVID era, that the Canberra-based consultant fully realised the overwhelming number of architectural constraints he would be facing in this heritage-listed building—not least the demanding acoustics, with multiple reflections created by a 22m-high dome.

The reason intelligibility was such a concern was because a large proportion of the congregants are elderly worshippers, struggling to understand spoken word services. The existing speaker system simply did not meet the requirements, as it consisted of too many non-compatible enclosures, randomly installed as new extensions had been added over time.

But speech wasn’t the only consideration as St John’s also hosts more contemporary music for its youth services—as well as orchestral and pipe organ recitals.

After evaluation, Tim Kuschel’s upgrade solution to provide enhanced coverage in the sanctuary, platform and presentation areas, came down in favour of Martin Audio’s multi-award-winning O-Line modular micro-array set-up, with scalable resolution. “This offered the most consistent results across the seating areas,” he rationalised. “With its compact form factor, O-Line excels in houses of worship where speech intelligibility is the primary function.”

GUZ BOX had arrived at this solution only after conducting extensive acoustic measurements using EASE software, to ensure that the loudspeaker energy was focused on the main church seating areas, and that the sound would operate within the full frequency range for speech and music, setting a desired Speech Transmission Index (STI) and other key parameters.

WITH ITS COMPACT FORM FACTOR, O-LINE EXCELS IN HOUSES OF WORSHIP WHERE SPEECH INTELLIGIBILITY IS THE PRIMARY FUNCTION.

Tim Kuschel, Founder, GUZ BOX design audio

He built a model in AutoCAD, converted it into a virtual acoustic model using AFMG’s EASE version 5 and correlated the physical measurements with the EASE model. He also worked closely with Cumulus Studio by proposing an extensive acoustic works treatment programme, including ceiling absorbers and wall treatments.

Working closely with Martin Audio distributor Technical Audio Group (TAG), he detailed two hangs of 16 Martin Audio O-Line elements.

For the ability to reproduce music, however, he recognised that additional subwoofers would be required. Thus low-end extension is provided by six of Martin Audio’s SX110 10in direct radiating sub bass arrays, equally spaced across the front of the stage under the main platform. Each was individually amplified and processed to optimise steering.

However, the installation was not without its challenges. Unable to suspend the main arrays from the 22m-high concrete dome—due to it being 16m higher than the optimum speaker placement—in order to achieve optimum coverage, in line with the modelling prediction the top speaker of each hang was suspended 6m above the sanctuary floor. This required customised speaker brackets to be fabricated, to extend the distance of the arrays from the wall. The 16 pairs of loudspeaker cable were also concealed within the mounting bracket. “It was a pretty neat solution all round,” reasoned the consultant. “The installer did a great job with this.”

Tim Kuschel turned to Martin Audio’s proprietary DISPLAY 2software, deploying the ‘Hard Avoid’ feature largely to avoid spill back onto the stage/platform area. In this case, single-element resolution was used for optimised coverage over the audience area.

Other infill speakers have been strategically placed including several Martin Audio CDD6 and CDD5’s, which have been fixed in the side chapel and chancel/choir stalls on ball and ceiling brackets. These were chosen for directional characteristics and form factor.

As for aesthetics, the O-Line elements (and other Martin Audio loudspeakers) were installed in standard colour finish, however all other fixings including cable-runs in conduit were colour-matched where possible to satisfy heritage requirements.

Other project considerations included independent wireless iPAD control for the clergy, enhanced assistive listening, isolation from other interference and advanced acoustic treatment (as well as carpet absorption). The latter included an aesthetic acoustic treatment of Megasorber C50 50mm sound absorbing panels to approximately two-thirds of the ceiling over the main seating areas.

Tim Kuschel can reflect with satisfaction on a project in which all his goals were met. The reverberant energy over the audience area has been controlled and the new audio system provides a minimum measured STI value of 0.61 from the front row to the last seat of the balcony­—with the speech clarity uniformly intelligible throughout. He has ensured intuitive control and management by non-technical staff in whatever mode the system is set up.

He has also struck the right RT60 balance, recording 2.5s of reverberation time, mainly in the mid-frequencies. “The organist demanded reverberant energy in the space, and it was pleasing to note that this has been unaffected by the acoustic works,” he noted. “Crucially, the reflected energy has been controlled and so the performance of singers and musicians is not compromised.”

Installation works were carried out by Tasmania-based Contact Group, while T-Built project manager Joel Taylor coordinated and managed all the onsite contractors and systems integrators.
