Panaray® MA12 Modular Line Array Loudspeaker

TECHNICAL DATA SHEET

Key Features • Designed to deliver high speech intelligibility in indoor acoustically demanding spaces • Music performance from 155 Hz to 12 kHz (-3 dB); for full-range music performance, additional bass augmentation is required • Wide horizontal dispersion for broad 145° coverage • Available in black or white, paintable

Description The Panaray® MA12 modular line array loudspeaker is designed for indoor applications where speech intelligibility is critical and speech reproduction is the main requirement. To deliver full-range music performance, bass augmentation is required. The MA12 loudspeaker can be mounted in single or multiple loudspeaker configurations. This loudspeaker is well-suited for indoor applications such as houses of worship, auditoriums, transportation hubs, atriums, malls, gymnasiums and multipurpose spaces.

Modular Line Array Loudspeaker How our Loudspeakers are Measured

The loudspeaker shall be a multiple driver system with matched active equalization as follows:

1. Frequency Response and Range

The transducer complement shall consist of twelve 2.25" (57mm) mid/high-frequency drivers mounted in vertical line array. Each driver shall have a rated impedance of 6.2g and wired in series/parallel, resulting in a composite nominal impedance of 8g. The nominal horizontal beamwidth of the loudspeaker shall be 145°, and the vertical coverage is a band of constant height. The power handling capacity of the loudspeaker shall be 300W continuous pink noise, band – limited from 155 Hz to 12 kHz (-3 dB). The loudspeaker shall be provided with a ducted vent system, tuned at 150 Hz. The input connector of the loudspeaker module shall consist of two parallel-wired Speakon® NL4 receptacles and one two-conductor barrier strip. The enclosure of the MA12 loudspeaker module shall be aluminum. Its outer dimensions shall be 38.8" H x 4.2" W x 5.1" D (986mm x 107mm x 130mm). Its weight shall be 18.7lbs. The loudspeaker shall be the Bose® Panaray® MA12 modular line array loudspeaker.

Safety and Regulatory Compliance The MA12 loudspeaker complies with ANSI/EIA636 Recommended Loudspeaker Safety Practices.

Rigging MA12 loudspeakers can be mounted as a single element or stacked in multiples to achieve line array performance. Bose MA12 loudspeaker mounting brackets are available and tested for use with single-, double- and triple-stack MA12 loudspeaker installations. For installations of four or more MA12 loudspeakers, obtain your mounting system from a reputable manufacturer. Select a system design that works for your loudspeaker of choice and its intended use. Always have a licensed professional engineer review the design and fabrication for structural integrity and safety in the intended application.

Data is the average response in the typical coverage area with the recommended equalization applied.

2. Calculated Max SPL Calculated based on input sensitivity with recommended equalization applied and maximum input power rating exclusive of power compression.

3. Input Power Rating Pink noise with a 6 dB crest factor is bandpass limited to the operating range of the loudspeaker and applied for 100 hours.

4. Axial Sensitivity Full-bandwidth pink noise with recommended equalization amplified to a level of 1 watt and applied to the loudspeaker in an anechoic environment.
