MLA

The MLA is a three-way active Multicellular loudspeaker with each cell comprising of a drive unit, a Class D high power, high
efficiency amplifier and comprehensive digital signal processing. There are six cells in total, three high frequency, two mid and a
low frequency cell comprising of a pair of 12"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 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 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 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 six 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 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 is designed for use outdoors in virtually any weather conditions so is rated to IP24. Electrical systems are protected by
a waterproof flexible cowl.
The cabinets are elegantly styled with a wrap over grill and injection moulded rubberised end cheeks that as well as adding to
the visual aesthetic make for easy and stable stacking in trucks or warehouses. A large bar handle makes handling and rigging
the system an easy job and each cabinet is supplied with a front-mounted wheelboard and protective canvas cover.
