1. APPLICATIONS The 12P combines the significant advantages of LACOUSTICS coaxial point source technology with the convenience of self powered performance and the power of digital signal processing Ideal for multi purpose portable sound reinforcement the 12P features advanced loudspeaker compo 1000 W amplifier module with dedicated nents powered by a on board digital signal processing Four application engineered presets are available FILL FRONT MONITOR X OVER complementing the conside rable flexibility of the I 12P by providing convenient plug and play ease of operation Featuring a 4 exit compression driver coaxially loaded by a 12 transducer the 12P provides coherent point source radiation with 90 degree axi symmetric directivity identical horizontal vertical and axial coverage Due to the coaxial component configu ration power response is free of the polar lobing effects typical of traditional horn woofer combinations The net result is natural studio monitor sound quality ideal for proximity fill use or portable distributed sound reinforcement in theatre congress centre concert hall trade show corporate A V house of worship club or television applications When used with the L ACOUSTICS SBI5P self powered subwoofer the 12P is also highly suitable for side fill drum monitoring or medium format front of house FOH applications Due to its compact wedge shaped enclosur2.
