Wacken Metal Battle Concert, held at Amoranto Stadium in Quezon City of Manila, Philippines, saw a crowd of 15,000 as metal bands from the Philippines fought to be featured in the Wacken Open Air 2023 concert in Germany in August. A total of 18 local bands performed along with seven bands from various countries like Japan, Australia, Bangkok, Indonesia, Taiwan, USA and South Africa.

OnePro Corporation Professional Sound and Lights based in Manila was contracted to handle the sound for the 14-hour concert, selecting Audiocenter as its preferred PA system in order to meet requirements from the bands involved.

OnePro deployed Audiocenter’s K-LA212-DSP, which is a two-way Active Bi-amp line array module designed for live sound reinforcement. The rig consisted of 12 cabinets per side of K-LA212-DSP. Additionally, K-LA210-DSP was used as stage outfills with 12 cabinets per side with two 10-inch customised woofer from Beyma.

OnePro also utilised 18 Audiocenter K-LA218-DSP, with front loading subwoofers strategically positioned in front of the stage to deliver bass. The side fills for the stage were deployed with two clusters of Audiocenter K-LA12A line arrays, with each cluster containing two units of K-LA12A and two units of K-LA118. The on-stage monitoring was provided by Audiocenter WM-DSP speakers. Front fills were taken care of by K-LA12A.

The complete Audio System was aligned and tuned by Audiocenter’s systems engineer, Roshan Malim, who oversaw the entire system setup for this tour. Reg Rubio, the director for the Wacken Metal Battle is said to have very much enjoyed the concert.
