C Series powers the luxury at JW Marriot Hotel - Pune, India


With an enviable reputation across the globe, Tannoy and Lab.gruppen’s superior quality sound was recently sought after for one of the country’s most luxurious, and indeed renowned, hotels – the five-star JW Marriot in Pune, India.
In the world of luxury hotels, sound systems might not always come on top of the agenda when it comes to capturing opulence. However, the JW Marriot is one such residence which has managed to gather the required demeanor to gain its five-star status, and now, thanks to Tannoy and Lab.gruppen's sound technology, it has the kind of technology fit for such surroundings – inside and outside the building.

The project to bring this signature sound began when Panchshil Realty, a multi-asset class Real Estate Development company based in Pune, were tasked with helping the JW Marriott ‘redefine hospitality’ in the city. Panchshil Realty immediately looked to leading AV consultant and designer Sachin Jain of PLAY, a specialist in system integration, who knew exactly what solution was required for a job of this scale.

Sachin explained further, “The JW Marriot is one of the busiest hotels in Pune and the project meant coming up with a solution that would make a statement and redefine hospitality in the city. Very few hotels in India could compare to this hotel, in terms of the finishes, in terms of the interior, and now, in terms of the sound technology. Not a lot of people give us the opportunity of using the right product, the right quantity - people want to save costs on various factors, but not this hotel. They have not tried to save costs but used the optimum product and the optimum technology. The whole design of the hotel is about offering not just the best in the country, but it also aspires to be one of the best in the world, so the technology infrastructure should meet this aspiration.”

Sachin explained that the thinking behind the project was to get a more detailed design, and a consultant such as himself who would be more actively involved in the project, who could understand the requirements, and as he puts it, ‘design spec the right products', the 'right equipment', and ultimately, the 'right solutions’. Leading system integrator S K Office Solutions then had the task of installing this system up to the standard that was required for such a prestigious development.

Speaking of the possibilities of installing the products, Sachin continued. He said, “Audio in this hotel is digital which is not very common in India – with these products, you can now route music from any floor to any floor, any source to any other place. You also have dynamic volumes controls in place in various zones which are then digitally attached to your central rack which is in a centralized location.”

Tannoy was brought on board because the client demanded only the best, and was not prepared to compromise on quality.

“We saw various globally-renowned brands and obviously came across Tannoy as one of the major options for loudspeakers,” Sachin explained.

“Firstly, we were really impressed with Tannoy as a brand; the CMS series, the 501DC, the ICT series, the sound from these products were fantastic and that really impressed us. Although it was a premium brand and it meant spending more, compromise was not an option. The owners were also very particular about the quality of sound of music and overall sound they were going to have – that’s what put Tannoy in the driving seat, and that was the deciding factor. In all aspects such as design, build quality, reliability and overall sound, Tannoy were the brand that stood out from any of the others.”

Krishna Singh, Indian Sales Manager for Tannoy and Lab.gruppen, commented: “Tannoy’s CMS Series is simply the best ceiling speaker on the market. It features studio grade drivers and offers a level of clarity and coherent sound that simply can’t be matched by any other brand. The real test comes during demonstrations; as soon as the client hears the difference you get with CMS Series, the demand is there. That ‘no compromise’ ethos behind this project suited the product perfectly.”

In total, over 400 Tannoy loudspeakers were used throughout the project, mainly CMS Series complemented by Di and VX Series for extra reinforcement in the areas that required it.

“I think Tannoy has done a brilliant job in terms of the product quality and the production. In areas [of the hotel] you will see the speakers blend into the aesthetics and gives that stunning sound that with visual appeal. It’s all turned out well and people have appreciated it – the hotel has got a lot of good reviews across Asia and today features as one of the top hotels in India and is still the busiest hotel in Pune. That makes you appreciate being involved in a project such as this.”

The choice of using Lab.gruppen C Series amplifiers also worked to perfection within the given environment. C Series amplifiers are uniquely capable of adapting to a wide variety of demanding load conditions. Each channel has an individually configurable Voltage Peak Limiter (VPL™), which allows the output to be optimized for any loudspeaker load – whether a single large subwoofer or a series of small 70 V loudspeakers (100 V in bridge mode). VPL works in combination with adjustable input gain to achieve maximum headroom regardless of input levels or output impedances.

Sachin explains: "Because of the amplifiers' small 2RU design, we could save a lot of space in the controls room and this really helped us during the install phase. The products flexibility offers control of various gains and variable power on different channels – that is an added benefit because in hotels, you have 3 or 4 different loops and not each loop would require the same amount of power that runs into that. Lab.gruppen have been extremely flexible and helpful, and on hand 24/7 over the last 3 years to help us with any questions or problems, and that kind of back up support is invaluable on a project of this scale."

Apart from Tannoy speakers and Lab.gruppen amps, the other core components of the public address system include three Biamp AudiaFLEX units with input/output cards housed in a central rack. The music and audio for each zone is routed via a CobraNet network to distribution boxes in the various zones of the hotel. A PC streams music to the AudiaFLEX system, while distribution is the achieved by collating feeds of analog output from CobraNet distribution boxes to the Lab.gruppen amplifiers located in key locations throughout the hotel, which then feed the Tannoy loudspeakers.

“Each floor of the hotel has been configured as a separate zone and each zone is provided with a Biamp RED Ethernet control device to control the volume of the zone manually, “ commented Sachin.

Of course, with a modern public building such as this, the public address system will become part of the evacuation system in the event of an emergency, as Sachin explains: “As soon as the fire alarm panel detects an alarm for a specific floor, the music that is being streamed will immediately stop on that floor and an emergency message will start playing. It’s all just part of a coherent and well put together system that has been expertly installed. The whole job is something that I am very proud to have been part of.”

The JW Marriot is now fully tailored, completely fitted, top-to-bottom, in the latest Tannoy and Lab.gruppen sound excellence, giving a complete 'uniformity of sound'. “I am very pleased with the technology infrastructure at our JW Marriott Pune property,” said Mr Abhay Chordia, Jt Managing Director at hotel owners Panchshil Realty. “I believe our property would be the most advanced in the country with regards to the AV technology. Our intention, which has been successfully implemented, has been to provide the business centre guest with similar or better infrastructure they have been using in their office. We strongly believe that technology and the functionality it provides goes a long way in providing a complete guest experience and is equally important as the interior design of a space. Each space in this property has been equipped with the best products in the world and designed to meet the functionality of the space.”
