MK3 Technical Overview

The MFLA-MK3 is a dual 12” line array element featuring dual 3” voice coil, 1.4” throat compression drivers, a 3000W amplifier and an integrated DSP. Low current draw and light weight relative to their output capacity means you can provide intense sound with less power and fewer boxes.

The comprehensive processing ensures consistent, undistorted high-SPL operation and maximum reliability. All the processing necessary for linear frequency response and phase coherent operation are pre-programmed into the DSP, delivering exceptional dynamic resolution and detail along with precise control.

The proprietary processing programmed into the BASSBOSS MFLA-MK3 provide the ease of plug-and-play operation and very simple and easy setups. You also get the peace of mind that comes from knowing that the integrated limiters make the system capable of operating reliably at extremely high output levels.

The MFLA-MK3 cabinet features innovations in performance and practicality. The forward output of the dual 12” woofers passes through a multi-aperture diffraction matrix that distributes mid-range energy evenly and in phase over the height of the cabinet. This matrix effectively reduces the acoustical source spacing to provide exceptional projection of mid- range frequencies. The matrix also shifts upper-midrange frequency output toward the center of the cabinet, which broadens the horizontal dispersion of the midrange frequencies.

This technology allows the MFLA-MK3 to deliver coherent midrange propagation from a symmetrical 2-way design, which not only eliminates the phase offset, (or latency,) of a 3-way system, it also allows for higher midrange SPL and lighter cabinet construction. The shorter acoustical path of this system allows the high frequency lenses to be utilized for extremely wide horizontal coverage, often even eliminating the need for front-fills.

The rear output of the woofers enters a vented enclosure that features integrated damper structures that enhance midrange clarity along with extensive bracing for minimal resonance. The vents are perpendicular to the cone movement to further improve midrange clarity, minimize cabinet frontal area and to provide for wider horizontal coverage capability, all while they do their primary duty of delivering exceptional low frequency performance. Their location also provides the secondary function of ducting cool air directly over the low-frequency driver motors for reduced thermal compression and improved reliability.

Fixed-Point Flyware ensures absolutely consistent box-to-box alignment. The high-frequency output of an array can only remain coherent at higher frequencies if the cabinets cannot move front-to-back once the pins are inserted. The MFLA-MK3’s unique precision alignment mechanism prevents movement in the direction that influences time domain alignment, front-to-back, which is critical to ensure the phase of the high-frequency signals remain coherent from box to box. This feature dramatically improves the very high-frequency propagation effectiveness of the entire array, allowing the MFLA-MK3 to deliver pristine highs at greater distances.

The MFLA-MK3 Flyware features a simultaneous compression and tension mechanism, allowing the cabinets to be flown or ground stacked using the same simple setup. The proprietary flyware design ensures there is no slack and no shifting in the box alignment once the boxes are pinned. The mechanism allows for single-handed adjustment of splay angles for ground-stacked operation or in preparation for flying.

Setting up the MFLA-MK3 Line Array

Using the Rigging System

The MFLA-MK3 Line Array has recesses on one side and sliders on the other. The sliders are located at the bottom of the cabinet. The rigging hardware includes single extensions at the bottom front and double extensions at the top front.

There are two holes just behind and below the pivot point of the cam. These holes line up with holes in the cam and are used to lock the cam into specific positions before the cabinets are flown or secured.

Bottom of Array Position

This is the upper hole and is used only for the bottom cabinet in a flown array. It keeps the cam clear of the tuning ports. For cabinets in other positions, this hole will not be used.

Transport Position

This position uses the lower hole. Use it to lock the cam above the bottom of the cabinet when moving it by hand. Push the handle down until the cam’s upper edge is centered on the port in the side of the cabinet, then insert the pin into the lower hole behind the pivot.

Landing Position

This position is also aligned with the lower hole. It corresponds to a 1-degree angle, making it easy to land arrays onto carts or additional elements with minimal splay. Lift the handle near the top of the cabinet until another hole in the cam is exposed. Align this hole with the lower hole and insert the pin to lock it in place.
