Lightly used, and in excellent condition Bose Panaray MA12 Line Array Loudspeaker (buy all 4 and get couplers and mounting hardware at no additional charge!)  PANARAY® MA12 Modular Line Array Loudspeaker What is the PANARAY® MA12 modular line array loudspeaker? A high-performance, full-range, line array loudspeaker for reproducing voice and music in venueswhere clarity, intelligibility and elegance are essential. The line array’s unique characteristics enablesound that is not too loud for listeners close to the speaker, and not too soft for those far away. TheMA12 speaker is designed for placement at ear level and radiates a wedge of sound at a near con-stant height, significantly reducing ceiling and floor reflections. Why is it called the MA12? Because it is a modular line array with 12 drivers. How does the PANARAY MA12 modular line array loudspeaker fit in the PANARAY productline? The PANARAY MA12 loudspeaker is a powerful new addition to the line of Bose loudspeaker forengineered sound. It is designed to offer the unique benefits of line arrays for installed and portablesystems. What does the PANARAY MA12 modular line array loudspeaker add to the Bose®Professional Systems product line? Due to its line array behavior (wedge-shaped radiation pattern and more gradual intensity roll-off), it ismounted at ear height and therefore allows us to better solve customer problems at lower overallproject cost than conventional systems. What are the main applications for PANARAY MA12 modular line array loudspeaker? The MA12 delivers quality sound for voice. And when paired with the MB4 bass loudspeaker, a power-ful full range system can solve many customer problems. For rooms with high reverb times, the MA12performs exceptionally well. PANARAY® MA12 Modular Line Array Loudspeaker What is the main difference between the PANARAY® MA12 modular line array loudspeakerand other loudspeakers? The MA12 offers a wide dispersion pattern with a flat vertical profile. The speaker should be mount-ed at ear height to place the listener's ears wihin this “wedge of sound”. The MA12 is ideal for applica-tions with floor and ceiling reverberation concerns. Its longer throw and gradual roll-off offer a moreeven SPL throughout the venue. It is simple and convenient to install and service. What is distinctive about the PANARAY MA12 modular line array loudspeaker? Its characteristics are that it uses 12 small drivers (2.25", 57mm) that are full range from 100Hz to16kHz. The drivers are densely packed resulting in high power handling (300W) and true line arrayacoustic performance. Why is the MA12 loudspeaker 1 meter tall? In order to produce the line array characteristics we require, we needed the speaker to be at leastone meter tall. The 1-meter (39-inch) length is simple to handle and may be easily stacked to createtaller line array solutions. What is a cylindrical waveform? A cylindrical waveform is a unique characteristic of a pure line array. The sound emanates from theloudspeaker in a wedge without dispersion upward or downward from the source. The sound pres-sure level rolls off by 3dB per doubling of distance. What are the rules for using multiple PANARAY MA12 modular line array loudspeakers? The bottom of the array has to be at or below the chest height of a person sitting in the first row, andthe top of the array has to be higher than the head of a person standing in the last row. All the listen-ers’ ears must be contained in the “wedge of sound.” A slight pitch from 1 - 10 degrees may be puton the speaker to eliminate reflections off the rear wall as long as the listeners’ ear heights are stillcovered within the line array. PANARAY® MA12 Modular Line Array Loudspeaker Must the PANARAY® MA12 modular line array loudspeaker always be used vertically orcan I mount it horizontally? The speaker must be used vertically only. Horizontal installation will reflect sound on the floor andceiling compromising clarity and intelligibility, and only provide a narrow band of sound horizontally. Is the PANARAY MA12 modular line array loudspeaker passively or actively equalized? The MA12 requires active equalization. Active equalization ensures balanced low, mid and high fre-quencies in the loudspeaker. In addition, it provides high and low band pass filtering for speaker pro-tection What accessories provide active equalization for the PANARAY MA12 modular line arrayloudspeaker? The PANARAY MA12 modular line array loudspeaker has two sources of Active Equalization:• PANARAY System Digital Controller for active equalization • MA12 EQ cards for use with Bose® M2150, 1600VI and 1800VI amplifier input cards. Why do I need the PANARAY System Digital Controller? The MA12 – like most other Bose PANARAY speakers – requires active equalization to provide a bal-anced frequency response and to protect the speaker. In addition to active equalization, thePANARAY controller also provides programmable delay, limiting and routing. What setting relevant to the PANARAY MA12 modular line array loudspeaker are preset inthe Panaray System Digital Controller? The PANARAY system digital controller has multiple presets for systems using a single MA12 loud-speaker or a stacked pair of MA12 speakers in either mono or stereo, and MA12 loudspeakers witheither MB4 bass or 502®B bass speakers. What brackets are available for the PANARAY MA12 modular line array loudspeaker? There are four types of brackets that each come in black or white: • WB-MA12 • WBP-MA12• CB-MA12 • PS-MA12 Wall bracket with 0-10° pitch BI-pivot wall mount bracket with 0-10° pitch and +/- 90° yaw Coupling bracket for use when stacking two or more MA12 loudspeakers.Stand bracket to attach MA12 to SS-10 stands PANARAY® MA12 Modular Line Array Loudspeaker Can the PANARAY® MA12 modular line array loudspeaker be used with other Bose® loud-speakers? Yes. In fact, the same way that most systems today are comprised of various Bose speakers,future systems can be built from a variety of Bose speakers that include the MA12 loudspeaker. Anexample is a church where you could use MA12 speakers to cover the main floor and PANARAY302TMA speakers to cover the balcony. What bass loudspeaker should I use with the PANARAY MA12 modular line array loud-speaker? You can use any bass speaker. Depending on the application, combine the MA12 with one or morePANARAY MB4 modular bass loudspeakers, or PANARAY 502®B AcoustiMass® bass modules. How many PANARAY MB4 modular bass loudspeakers go with one, two or morePANARAY MA12 modular line array loudspeakers? For typical music applications, we recommend two MB4 loudspeakers for every two MA12 speak-ers. What crossover frequency should I use when using the PANARAY MA12 modular linearray loudspeaker with the PANARAY MB4 modular bass loudspeaker? 180Hz using a fourth order roll off. The PANARAY System Digital Controller preset is: MA12+MB4. How should the PANARAY MA12 modular line array loudspeaker be placed in a room? Place it at ear height and in the front of the room. Never hang-and-tilt an MA12 loudspeaker. What size amplifier do I need to drive one PANARAY MA12 modular line arrayloudspeaker? We recommend a single channel of a Bose 1600 VI amplifier with 300W of power or a singlechannel of an 1800 VI amplifier with 450 Watts per channel. Can I use the PANARAY MA12 modular line array loudspeaker in a 70V or 100V system? Yes. A 70V/100V-transformer for the PANARAY MA12 speaker is available.

A single module can cover a wedge shaped area of 170° and a throw distance of approximately 60feet (18 meters). A vertical array of two MA12 speakers (2 meters high) can throw approximately90-100 feet (30 meters). What happens when I stack two PANARAY MA12 modular line array loudspeakers? A stacked pair of two MA12 speakers has the same horizontal dispersion of 170°. It gives yougreater vertical control of the lower frequencies between 100 and 500Hz. What is the maximum height of stacked PANARAY MA12 modular line array loudspeak-ers? The joining bracket allows you to safely connect two MA12 modules and use either of the wallmount brackets. If more modules are needed, then for every two modules an additional wall mountbracket is required for safety. What is the maximum length of a room that can be covered by two PANARAY MA12modular line array loudspeakers? In a typical application, two stacked MA12 modules can cover up to 100 feet. For detailed informa-tion and layouts see the Bose® Modeler® software. Can I recess a PANARAY MA12 modular line array loudspeaker in the wall? Yes, but the front should be flush with the wall surface to keep from limiting the horizontal disper-sion. What colors are available for PANARAY MA12 modular line array loudspeaker?
