The MLA3-2i is a 3-way, axisymmetric large format line array system designed specifially for permanent installatin. The system is engineered to deliver high defiitin, high SPL sound reinforcement for a broad range of applicatins, including concert halls, stadiums, and large clubs.
Each MLA3-2i line array cabinet features two manifold loaded 12” McCauley 8231 Low-Mid drivers, two 77087 8” Midrange Drivers and two 1.0” exit compression drivers on a 90° x 10° slot-loaded wave guide.
The McCauley 8231 Low-Mid driver is built around a new fild serviceable motor with integrated aluminum heat sink. The new motor design has a thinner, 0.3” top plate and longer 0.9” by 4.0” diameter aluminum coil which improves the linearity of the Bl vs. displacement profie. The 8231 Low-Mid driver features a hybrid composite-paper cone which balances light weight and high stifess, to improve overall sensitiity, with the internal damping that is inherent to paper cone loudspeakers.
The coupling of the cone drivers and high frequency waveguide has been specially engineered to produce a rich and fully balanced sound from 50 Hz to 18 kHz. The 8231 12” low-mid drivers are manifold loaded to improve the sensitiity over their operatig band and increase array density. The 77087 8” midrange drivers are phase plug loaded to match the pattrn of the HF around the crossover frequency and reduce cabinet to cabinet interferences. The HF slot loaded waveguide is optiized to reduce resonances which would require DSP equalizatin. The sensitiity of each component has been specifially engineered for the MLA3-2i to allow for the extra HF headroom which is oftn required in longer throw applicatins.
