High power, self-powered Class-D Three-Way Line Array CabinetPrevious page


Extremely high power, Self-powered Class D with PFC (Power Factor Correction), three-way Line Array. Dual LF 12” (4” interleaved sandwich voice coil) neodymium woofers with double demodulating rings, Four MF 6.5” transducers with glass fiber cones & ultra-light voice coil and two HF 1.4” neodymium magnet drivers with titanium diaphragm and individual high precision wave guide. DSP (FIR technology) controlled with 4,000W amplification, 143dB SPL, built-in inclinometer.

The BLX-L212A is part of the BLX Line Array Series. Line Array topology is employed to create cylindrical radiation, increasing throw and achieving a precise control of both horizontal and vertical dispersion. The BLX-L212A is the ideal solution for application in theatres, concert halls, stadiums, auditoriums, conference halls or any event where high precision Line Array is required.

The BLX-L212A is a very high output three-way self powered cabinet. For the low frequencies it uses dual 12” neodymium transducers with interleaved Sandwich Voice Coil (ISV) & Double Demodulating Rings (DDR). The mid range is looked after by four 6.5” transducers with glass fiber cones & ultra-light voice coil. The high frequencies use two 1.4” neodymium magnet drivers with titanium diaphragm, each with its own individual high precision wave guide. The system is powered with a total of 4.000W of class D amplification, 2.400W for the low frequencies, 1.000W for the mid and 600W for the high frequencies. Each cabinet has a DSP integrated which applies linear phase (FIR) and classical crossovers. Other features include temperature sensor, fan speed control, inclinometer, Ethernet options and many more.

The BLX-L212A has a selection of rugged hardware available. The BLX-L212/FL flying frame can hold up to 16 cabinets with splay angles selectable in 0.5o increments between 0o to 3o and 1o increments between 3o to 12o. The BLX-L212/TD transport dolly can house up to 4 cabinets and a nylon protection cover (BLX-L212/4NC) is also available. Rain hoods (BLX-L212/RC) are also optional to protect the system electronics. With a very high power to size ratio and with easy rigging options offered the system can be taken from the truck and rigged up in record time. It is also very easy to use and control without the need for any external amps. To extend the low frequency response, the BLX-318SWA Cardioid sub bass is recommended.
