The LA2 10 linear array is a high-end sealed loudspeaker with a patented acoustic wave shaping lens device called line element. It is installed on the patented DE horn.
Traditional speakers are spherical wave fronts-a bit like blowing bubbles-and when used with other speakers, interference and phase zeroing appear on the same wave front over a certain distance. In order to make the linear array work, it is necessary to have a narrow vertical scattering shape and a flat (or slightly curved) wavefront, which is beneficial to use with adjacent speakers. In order to achieve this goal, many manufacturers use a lot of long horns that have gradually become obvious. Theoretically, these long speakers can make sound waves travel farther, but in fact they sound like the sound in a pipe.
The patent line element is only 1 inch thick. It is made up of many laser-cut steel plates stacked and fixed by bolts. Many signal paths are only a few inches long, but they form a balanced and flat wavefront at the throat of the horn-in fact, these small radians allow the small chamber-like linear waves to bend to expand the vertical coverage. The two BMS Nd magnets 1 "drivers come from the driving components provided by GA Company in Germany.
Line components are installed on the DE horn, which is also equipped with two B&; Cone speaker of c10 "d. Behind the unit is a completely closed box. Speakers are installed on the horn side plate with two outlet holes, and each speaker has two small outlet holes. The exit aperture is completely located at the intersection of the timeline and the high frequency entrance. The result is that the full frequency range is smoothly combined with the loudspeaker, and the high frequency transmission distortion is small, and there is no destructive interference in design except the crosstalk of two conical speakers.
The bottom of LA2 10 line array series is L2 15 ultra-low loudspeaker, and patented loudspeaker design is introduced. In which two stereo 10 "speakers are installed, so the front end of the speakers is installed on the speaker channel closed with 8". The rear of the driver is located in the speaker channel, so it can provide additional phase output with the front of the speaker.
This is technology, very simple. What is the effect of his work? Very good.
The equipment in the live art center has 12 top speakers and 8 ultra-low speakers on each side. DELIYA DCX2496 4-input /8-output digital loudspeaker management system is used to divide the linear array into four coverage areas, which enables the floor and audience in the theater to be controlled independently. Ultra-low speakers are also distributed in four areas to meet the bass response of sound wave propagation in the horizontal direction.
In the cinema, I tested the continuous sound pressure level C value of 104dB (better than the sound pressure level A value of 100dB). The sound pressure in front of the ultra-low speaker is as high as 106dB, and the sound pressure in the first row of the lobby is as high as 107dB. But at this point, the band has reached the last group. You will expect to reach "25" or "6 to 4" when the drum and guitar perform alone, which is more stressful than Saturday Park. The coverage of the whole theater is very gentle, even if the horizontally placed bass is cut off. Bass is very musical, without bass noise and banging-some technical means are used here.
The LA2 10 linear array is very strong, and the box is composed of 5/8 "(15 mm) and1layer Russian birch, and the installable load is more than 5 times its weight, although the EL2 10 is only 89 kg.
LA2 10 linear array series introduces advanced technology, which overcomes some problems in the coordination of many devices. After thousands of hours of careful screening, the ideal product was selected from many originals. Its structure is very solid, and it is very careful in hardware-it can provide simple and quick installation problems and transportation. The sound I hear is beautiful. Surprisingly, this system is not expensive compared with similar systems-this is the pride of Canada!
