Martin Audio expands Differential Directivity systems
Combining state-of-the-art transducers with Differential Dispersion horn technology and Class-D amplification, the multi-purpose DD12 loudspeaker forms the latest addition to Martin Audio’s comprehensive range.
According to the manufacturer, its patented rotatable Differential Dispersion technology delivers a more consistent coverage than traditional X x Y horns. The two-way powered speakers also feature onboard DSP, a switched mode power supply with Power Factor Correction (PFC), and internal memory allowing for factory ‘plug-and-play’ or user-generated DPS preset snapshots to be recalled via a selector switch on the rear panel.
Whether configured as an element in a stand-alone system or part of a larger MLA/MLA Compact system, individual DD12’s can be controlled and monitored from a laptop or wireless tablet PC via the manufacturer’s VU-NET proprietary software. Connections to PCs can be made directly via USB, or via Martin Audio’s U-NET network and Merlin loudspeaker and network management system.
The cabinet supports surface, ceiling and pole mounting, and has a universal tilting bracket, making it suitable as a PA in small-to-medium installations.
As well as the DD12, Martin has also released the 15-inch self-powered PSX subwoofer. Intended as a companion for the DD6, XD12 and XD15 loudspeaker systems, it comprises a 4-inch voice coil, long-excursion driver in a reflex-ported enclosure. It houses two channels of Class-D amplification – one channel for itself and one channel to power an XD12, an XD15, or up to three DD6s.
Producing a total peak output of 2,400W – with 1,400W allocated to the sub and the remaining 1,000W to drive the associated system – the operating range of the PSX is 48 to 150Hz with a peak SPL capability of 136dB at one metre.
Onboard DSP performs delay, crossover and EQ functions, while like the DD12, the sub and its full-range system can all be controlled and monitored via VU-NET software.
The speaker housing is made from tour-grade plywood coated in hard-wearing polyurethane with a Declon backed steel grille protecting the cone. Practical features include a pole-mount fitting on the top surface, bar handles and protective skids. When stacked, the skids on the base of the enclosure align with recesses in the top of the enclosure below.
