Martin Audio MSX

Reflex Loaded Subwoofer

15” Subwoofer and Power Plant

Amplification, networking and DSP are all housed in MLA Mini’s companion MSX Power Plant, which includes 9 channels of Class D amplification – 1 channel for itself, and 8 channels to provide cellular drive of up to 4 bi-amped MLA Mini enclosures. Crossover, delay and EQ functions are implemented by a combination of IIR and FIR filters.

MLA Mini arrays and MSX’s can be remotely controlled over the U-NET™ network from a laptop or wireless tablet running VU-NET control software. Small-scale systems – such as the configuration of 4 x MLA Minis and 1 x MSX – can be set up to plug-and-play without external control, with onboard presets recalled by a rear panel selector switch.

The MSX is the same width as the MLA Mini and can be integrated into flown arrays or ground-stacked separately. It features a 15" (380mm)/4" (100mm) voice coil, long-excursion driver reflex-loaded in a very compact enclosure.

For complete installation versatility, the power plant module itself can be rack- mounted and its sub-bass amplifier channel used to power either an MSX or an alternative Martin Audio 4 Ohm passive subwoofer. For ultimate sub-bass performance, the MLA Mini/MSX combination can be used with the powered DSX subwoofer.
