MLA Compact

MLA Compact was launched as the second product in the multicellular range to bring the proven benefits of the large format
MLA system to a wider range of applications not requiring the full power and throw that MLA provides or where size and weight
restrictions call for a smaller lighter system. MLA Compact shares the sonic attributes of the flagship MLA and is designed for
medium-scale touring and fixed installations. Its compact size belies its output capabilities — a 12-box array can easily deliver
full rock SPL's in a 5000 seat venue, whilst a 24-box array will approach the output of many "full-size"systems which have less
efficient acoustic elements.
Scalable and versatile, MLA Compact is the ideal system for ballroom, theatre and HoW applications and is the natural choice as
a side-hang or front-fill for the full-size MLA.
The MLA Compact is a three-way active Multicellular loudspeaker with each cell comprising of a drive unit or units, a Class D high
power, high efficiency amplifier and comprehensive digital signal processing. There are five cells in total, two high frequency
comprising of a pair of 0.7"exit compression drivers, two mid, and a low frequency cell comprising of a pair of 10"bass drivers.
The combination of built-in amplification and DSP offers a hither to unheard of level of control in a compact, lightweight
loudspeaker. In conjunction with Display 2.1 system design and VU-Net network control software applications, outstanding levels
of consistent, high quality audio can be distributed to every point throughout the audience in a venue.
The MLA Compact has audio inputs that can be either standard balanced analogue or AES/EBU digital. A parallel connection is
available to daisy-chain between cabinets. The MLA Compact features network control via a U-Net interface which as well as
carrying all control data for the on-board DSP also feeds digital audio to the system. U-Net connections are made via a pair of
very high quality, rugged 8-way push-pull latching connectors rated for high speed data applications.
Mains connection is via a 16A Ceeform connector. A comprehensive mains distribution system is supplied as part of the MLA
system.
Each of the five channels of DSP comprises extensive processing optimised for the driver(s) under control, this includes delay,
parametric EQ, High and low pass filters, IIR all-pass filters, FIR low pass filter and EQ, gain, phase and limiting. In addition there
are user accessible parameters including delay, 10 bands of parametric EQ, high pass filtering, gain, phase and muting.
The MLA Compact system has a rigging system based on the existing popular and efficient Martin Audio line array systems but
with some innovative improvements. This allows phenomenally quick system rigging and de-rigging particularly in view of the
fact that there are no amplifier racks to set up and break down.
The MLA Compact is designed for use outdoors in virtually any weather conditions so is rated to IP24. Electrical systems are
protected by a waterproof flexible cowl.
