The new fourth-floor ballroom in Surabaya’s Ciputra World Mall has been equipped with an Outline Mini-Compass line array system by Indonesia distributor, Melodia Sound & Lighting Systems.
The PA system in Ballroom89, which is self-powered and driven by Outline’s iMode technology, comprises 12 Mini-Compass iMode elements and four DBS 18-2 iMode SP subwoofers, and covers an area of 700-sq-m that has problematic acoustics. The key feature of the Mini-Compass system – its ability to accurately steer sound where it’s required and keep it away from reflective areas – was decisive in its selection.
‘The Ballroom 89 management chose this system after taking products by two other brands into consideration,’ says Rudy Winarto, owner and MD of Melodia Sound & Lighting. ‘The first reason that led my client to choose Outline rather than the valid competitors was the “adjustable directivity factor”. I think that in the sound reinforcement sector there is no field of application in which this special “ability” doesn’t ensure dramatic benefits to the sound’s quality. Secondly, the system’s response at Ballroom 89 makes vocals more crystal clear, warm and “in the face” – even in the last row of seats – than I’ve heard before.’
The COMpact Polar Adjustable Sound System (Mini-MiniCompass) is a self-powered, bi-amped line array. Its two 1.75-inch compression drivers and four 5-inch mid-woofers deliver a peak SPL of 141dB at one metre with four enclosures. The cabinets provide a frequency range of 100Hz-20kHz. The units, including flying hardware, weigh 23kg (50lb).
Mini-MiniCompass is equipped with a pair of Outline’s Double Parabolic Reflective Wave Guides (DPRWG), a technology Outline patented for its Butterfly line-source elements. Thanks to the adjustable horizontal directivity, the coverage angle can be set between 60°-150° in steps of 15°, offering 16 combinations of horizontal coverage (including asymmetrical) to direct sonic energy where needed. The movable Mini-MiniCompass ‘wings’ help users avoid wall reflections and make other changes to coverage. Built-in sensors inform iMode’s DSP as to the positions of each cabinet’s wings, allowing automatic corrections to on-axis response.
