Panaray® MA12 Modular Line Array Loudspeaker

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.

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.
