Martin Audio has introduced the PSX, a new companion self-powered subwoofer for the DD6, XD12 and XD15 full-range loudspeakers.
It incorporates a 15-inch/4-inch voice coil woofer in a compact reflex-ported enclosure that houses two channels of Class D amplification, one channel for the sub and the other for powering an XD12, XD15, or up to three DD6 loudspeakers.
The Class D amplifier section is rated to produce a total peak output of 2,400 watts, with 1,400 watts allocated to the sub and 1,000 watts to drive the associated loudspeaker.
The amp’s switched-mode power supply auto-ranges to global mains voltages from 100 to 240 volts (50/60 Hz), and Power Factor Correction smooths the mains current draw over the whole of the AC waveform.
The operating range of the PSX is stated as 48 Hz to 150 Hz, with a peak SPL capability of 136 dB at 1 meter.
Onboard DSP performs delay, crossover and EQ functions, while the PSX plus full-range system can be controlled and monitored from a laptop or wireless tablet PC via intuitive VU-NET proprietary software. PC connection can be made directly via micro USB, or via Martin Audio’s proprietary U-NET network and Merlin loudspeaker and network management system.
An important feature of the PSX is its Internal memory, which allows factory “plug-and-play” or user-generated DSP preset ‘snapshots’ of the PSX/full-range combination to be recalled by means of a preset selector button on the rear panel, instead of using computer control.
The tour-grade plywood enclosure is coated in hard-wearing polyurethane and its Declon backed steel grille is pre-curved to resist deformation in the field. There’s a pole-mount fitting in the top surface, bar handles and protective skids. When stacked, the skids on the base of the upper PSX enclosure align with recesses in the top of the enclosure below.
