The 16th edition of the annual Jakarta International Java Jazz Festival (JJF) featured Nexo and Yamaha systems across most of the festival

Now one of the largest jazz festivals in the world, JJF 2020 featured performances from both local artists and international acts under the banner: ‘Redeem Yourself Through Music’. The event, which spanned three days in late February/early March, was attended by 110,000 people from Indonesia and surrounding countries at Jakarta International Expo (JIExpo), one of the largest exhibition venues in Indonesia. Headliners included The Jacksons, Omar Apollo and 34 other international acts, while more than 80 local artists performed across eight indoor and three outdoor stages.

Yamaha Musik Indonesia Distributor (YMID), which was appointed national distributor of Nexo products in Indonesia last year, staged an energetic initiative to deploy both brands across the festival. The company has already successfully built a network of rental users across the country. ‘This year’s JJF gave us a fantastic chance to showcase the latest products launched by Nexo, along with many Yamaha digital mixing console models,’ comments YMID’s senior general manager, Chick Hirai.

Two indoor stages, the Be One Hall and the Brava Radio Hall, featured Nexo’s new, mid-sized line array, the GEO M12 system. At the Be One Hall stage, the main PA system comprised 12 Nexo GEO M12s as main speakers and six RS18s in cardioid subwoofer mode, with three PS15-R2 high-power speakers placed horizontally with rotated horns for front-fill. Powered by three NXAMP4X4 digital amps, the system provided enough SPL to cover the 38m x 35m hall.

Initial system design was carried out on Nexo’s NS-1 simulation software, programmed by YMID’s technical support team and later verified and adjusted based on the actual conditions in the hall. ‘Compared to other halls that had more or less the same dimensions, I’m satisfied with the result of using Nexo GEO M12s, considering that we used fewer cabinets than other halls,’ says Norman Hajadi, the systems engineer overseeing the setup. ‘The NS-1 software is so accurate that it gave confidence to the systems engineers, hence minimising setup and tuning time.’

Adds Agi Hardono from Jakarta-based rental company, Don Sistem Suara Indonesia (DSS Sound System Indonesia): ‘The main problem that we always face at Be One Hall is the acoustics of the room, which are challenging because it is a huge, hangar-like building with a dome-shaped roof. A loudspeaker with directivity that can be controlled accurately is necessary; the Nexo GEO M12 proved to be very capable of conquering the problems in the room and also producing a natural yet beautiful sound.’

The sound system in the Brava Radio Hall was provided by Peplus Audio, one of many Yamaha console users at the event. Here, the main PA consisted of 12 Nexo GEO M12 speakers and a cardioid subwoofer array using 12 Nexo MSUB18 subwoofers, with two GEO M10 speakers set up as front-fills. Powered by three of Nexo’s latest-generation NXAMP4X4Mk2 amps, using Dante connection with analogue-fallback function activated, the system gave a safe, anti-dropout performance.

‘As an integrated system consisting of prediction software, various installation accessories and configuration and monitoring solutions for the amps, Nexo helped us form a fast yet accurate workflow,’ comments Rizky Pohan from Peplus Audio. ‘The accurate prediction software and the built-in DSP inside the NXAMP helped to minimise the negative effects, so we only needed to make minor adjustments to compensate for the room acoustics. This time–cost efficiency is crucial for a rental company.

‘Personally, I really like the frequency response of the MSUB18 subwoofer. It sounded really full, even though it only has a single 18-inch driver. Matching the sub’s crossover with the GEO M12 can be easily configured with built-in presets. Choosing the right cutoff point for the application in the venue was really quick.’

Peplus Audio and DSS Sound System are considered Yamaha rental partners as both have an inventory of CL and QL mixer series, with DSS being the first Rivage PM7 system owner in the country. Nexo speakers and amplification were supported by YMID with additional items supplied from IM Solution, one of Indonesia’s Nexo dealers.

Almost 80% of the stages were using Yamaha digital mixing consoles for FOH and monitor control, demonstrating the degree of acceptance that these systems have in the Indonesian market. Other Java Jazz rental companies providing Yamaha consoles for the festival included Soundworks and Total Audio. A Rivage PM10 and a PM7 digital mixing system were stationed in two indoor halls, the Top Coffee and Be One stages respectively, while the outdoor Java Jazz stage was equipped with a PM7. Eight Yamaha CL5s and a TF5 were provided for FOH and monitor duties across the other stages, with a Yamaha CL5 provided specifically for the performance of the all-star Yamaha Music Project in one of Java Jazz’s headline shows.

‘I am very grateful for the work put in by Yamaha Musik Indonesia Distributor and its partners during this festival,’ says Joe White, Nexo’s regional business development manager. ‘The Java Jazz festival is one of the most prestigious events in the Southeast Asian events calendar, and our GEO M12 mid-size line array being utilised on two of the festival’s stages exemplifies the wide acceptance of the GEO M12 system within the region as a whole. The M12 system, with its power-to-weight ratio and ease of use, clearly meets many of the requirements that rental companies have in this region. It is why we are very much looking forward to working hand in hand with YMID to further strengthen the reach of our GEO M PA solutions within the rental and the installation market.’

Yamaha also had a booth at the festival, showcasing its musical instruments by staging various live performances which were amplified by a pair of Nexo’s new P12 point source speakers plus four new Nexo L15 subs to handle the bottom end.

‘This year’s Java Jazz event was very special for us,’ concludes Hirai. ‘Delivering natural jazz sound is something we do especially well, so it’s a win–win for everybody. We thank our rental partners, users and dealers for supporting us, and for being appreciative of how Yamaha consoles and Nexo PA systems performed during the JJF event.’
