Barcelona, Spain (October 23, 2014)—Master Audio has announced its JK46A self-powered column array loudspeaker. The JK46A is intended for small to medium fixed installation and mobile reinforcement sectors, and includes LF response down to 50 Hz.

The lightweight, 4x 6-inch active column array loudspeaker system features custom-matched system components, including carbon-fiber coned neodymium drivers, class-D power amplification and 48-bit programmable DSP control.

The original Master Audio asymmetric horn, with PETP membrane compression driver, is custom configured with the four 6-inch carbon-fiber coned neodymium magnet drivers, aiming to provide directivity with uniform front-to-back audience coverage. A 700 W (1400 W peak) class-D power amplifier circuit design provides the cabinet with 125 dB SPL (128 dB Peak).

The integral DSP control—accessed from the rear mounted control panel with LCD screen—allows up to 40 m delay-line management and rapid selection of pre-set corrective EQs, while performing speaker management with a series of compression algorithms. The LCD screen provides information about input and output levels, system status and amplifier temperature.
