The Atlas A-Line EMMA active, modular line array system is a highly intelligible, high efficiency 3-way speaker system ideally suited for use in speech and music reproduction applications for medium to large venues like houses of worship, theaters and concert halls. The system consists of two parts: the EM806A-B, which includes eight 6.5" high frequency ribbon drivers and eight 6.5" low / mid frequency drivers and the EMW410A-B, which includes four 10" subwoofers. Each unit is powered by an integrated class D amplifier with pre‑configured DSP. Both models utilize an optimally designed Baltic birch constructed enclosure. The trim line, two cabinet design allows the units to be stacked to create a sleek, clean looking set up with minimal sightline interference.
