Ten Years After Audio Serves Major Thai Rock Concert With JBL VerTec Line Arrays

In a unique application that underscores the continued worldwide adoption of JBL Professional VERTEC® line arrays, Ten Years After Audio (TYAA), one of the leading audio rental firms in Thailand, provided the live sound system for the recent Assanee and Wasan Ram-Rai Concert at Rajamangala National Stadium in Bangkok. TYAA deployed VERTEC line arrays throughout the entire venue.

Brothers Assanee and Wasan Chotikul are popular, pioneering Thai rock artists. With a strong following of local fans and support by Thailand’s music industry for over 20 years, Assanee and Wasan are being heralded for having brought back the classic rock era of the ‘70s and 80s. Their latest production, the Assanee and Wasan Ram-Rai Concert, drew a sell-out attendance of more than 50,000 rock music fans. The event, organized by GMM Live in coordination with More Music, was hailed as the country’s biggest live music concert of the year in 2007.

The audio system included a total of 54 VERTEC VT4889 full-size line array elements, configured as 30 enclosures for left and right main arrays serving the open field, with four clusters of six VT4889 line array elements each for delay fill to the rear audience areas in the stadium’s seating rows. In addition, six VT4888 mid-size line array elements were employed as out fill for increased horizontal coverage. A total of 36 VT4880 full-size arrayable subwoofers were co-located with the main left and right arrays to provide extended low-frequency support for high-level music. All VERTEC loudspeakers were powered by a total of 70 Crown MA-5002VZ amplifiers.

Signal processing for all loudspeaker arrays was handled by six BSS Audio FDS-366T Loudspeaker Management Systems running JBL’s new V4 DSP presets, each working independently for their own zones. All incoming signal feeds for the BSS drive units came directly from the front-of-house mixer, for which Ten Years After Audio selected Soundcraft’s new flagship digital mixing console, the Vi6 Digital Live Sound Console. The event marked the first time a digital mixing console has been deployed for a major special event in the venue. All connectivity between the Stage Box of the Vi6 and the Local Rack in the FOH area was achieved via fiber-optic cable.

“Ten Years After Audio is a veteran concert sound firm, and with this show they have readily demonstrated how a properly-configured, multi-array sound reinforcement system operated by a talented audio crew can achieve excellent results for a large-scale live production,” noted David Scheirman, Vice President, Tour Sound for JBL Professional. “Stadium rock shows can be very demanding on both crew and equipment. The widespread acclaim for Assanee and Wasan’s Ram-Rai Concert is a testament to TYAA’s regional expertise.”

Technical assistance for the event was provided by Harman Pro’s exclusive distributor for Thailand, Mahajak Development Co., Ltd.
