MLA Compact brings award-winning Multi-cellular Loudspeaker Array [MLA] technology to medium-scale touring and premium fixed installations ranging from musical theatres and concert halls to Houses of Worship and auditoriums.

Features

  • Numerically optimised, fully-integrated, compact touring sound system
  • Cellular array format with built-in amplification, DSP and digital networking
  • 5 dedicated Class D amplifier channels per enclosure for individual powering and DSP control of individual cells
  • Industry leading DISPLAY2.2 intelligent software interacts with onboard DSP for highly accurate array optimisation Eliminates trial-and-error array preset library approximations
  • “Fly-by-wire” software adjusts vertical coverage electronically to cope with changing environmental conditions and last minute changes in rigging height. “Hard-avoid” areas, such as on-stage, ceilings and site perimeter, can be programmed in
  • Switched mode power supplies with PFC (Power Factor Correction) and global mains voltage operation
  • Three-way design delivers LF/MF/HF peak SPL’s of 135/135/135dB @ 1m from a single, compact enclosure
  • Fast, integral flying system for suspension of up to 24 enclosures
  • True 100° (-6dB) horizontal constant directivity, mid and high frequency pattern control. Consistent and usable out to 130° (-10dB)
  • 65Hz–18kHz ± 3dB full bandwidth frequency response

Benefits

  • Desired house-curve achieved right from power-up
  • Automatic, intelligent configuration and optimisation eliminates trial and error in system set-up
  • Improved venue-to-venue, gig-to-gig consistency and repeatability
  • Artistic changes to balance at the mix position (or elsewhere) translate directly and accurately throughout the audience
  • Exceptionally high powerdensity means tighter truck-pack for higher SPL compared to other systems
  • “Greener” audio power via PFC (Power Factor Correction)
  • Programmable leakage parameter to meet environmental noise constraints

Applications

  • Premium touring sound reinforcement for medium-size venues
  • Fixed installations in concert halls, theatres, ballrooms and HoW
  • Side hang for MLA festival and arena systems

I absolutely love the MLA Compact system. I’ve found it to be the most enjoyable system I’ve ever mixed on.

Architectural Specs

MLA Compact
Architectural Specifications

The loudspeaker shall be a self-powered, vertically-arrayable three-way system. Its transducers shall consist of two 10” low frequency drivers, two 5” midrange drivers each coupled to a constant-directivity midrange horn, and four 0.7” exit compression drivers each coupled to a constant-directivity high frequency horn. The drivers shall be configured to be driven as one low-frequency cell, two midrange cells and two high-frequency cells.

The loudspeaker shall incorporate a Class D amplifier module with five channels of amplification and DSP for independent drive and control of each cell. The amplifier shall deliver a total of 4.2kW peak output to the transducers and include networking capabilities to enable remote control and system monitoring. Its power supply shall employ Power Factor Correction and operate from 100-240V, 50-60Hz AC.

Audio connectors shall be male and female XLR type and the AC power connector shall be an IEC309 CEE Form.

The loudspeaker shall have 100° horizontal dispersion and 10° vertical dispersion. Vertical dispersion of the complete array shall be determined by a combination of the splay angles between adjacent enclosures and dedicated array control software. The on-axis frequency response shall be 65Hz-18kHz +/- 3dB and the loudspeaker shall produce a maximum SPL of 135dB peak at 1 metre.

The loudspeaker enclosure shall be constructed from multi-laminate birch and poplar ply with a textured black polyurethane coating. The drivers shall be protected by a perforated steel grille and the enclosure shall incorporate an integral rigging system to assemble an array of up to 24 enclosures suspended from a dedicated flying frame.

Dimensions (W x H x D) shall be 788mm x 280mm x 500mm (31in x 11in x 19.7in). Weight shall be 49.5kg (109lbs).

The loudspeaker shall be the Martin Audio MLA Compact.
