Martin Audio SXP118
Direct Radiating
Compact Powered 18" Subwoofer
Description
A self-powered system, the SXP118 incorporates a Class D amplifier, DSP and Dante™ digital audio networking — simplifying set-up, enhancing control and eliminating amplifier racks. The onboard amplifier delivers 2000W peak output to the driver, and its switched-mode power supply auto-ranges to global mains voltages from 100 to 240V 50/60Hz. DSP functions — including parametric EQ, delay, muting, gain and preset selection — can be controlled over Ethernet from a PC or Windows® tablet via intuitive VU-NET™ proprietary software.
For simple set-ups, ‘plug-and-play’ presets for operation with the CDD-LIVE 8, CDD-LIVE 12 or CDD-LIVE 15 — as well as a user-defined preset — can be selected on the rear panel, instead of using computer control. Additional presets provide the appropriate settings for the rear-facing subwoofer in a cardioid pair.
As an alternative to its analogue inputs, the SXP118 is Dante enabled for digital audio distribution and control over a single CAT5 cable to maintain audio quality however long the cable run.
The enclosure is constructed from multi-laminate plywood with a durable polyurea coating and equipped with a perforated Zintec grille, twin grab handles, skids, M10 flying inserts and a threaded pole socket.
The product is supplied as standard without cabinet wheels, but they are available as an accessory.
By adding the input board cover accessory, the subwoofer is fully weather resistant and suitable for permanent outdoor usage.
