Operating Instructions — USW-112XP

Compact Subwoofers

In this section:

The USW-112XP compact narrow subwoofer further extends the USW family. With its great power-to-size ratio, it provides big bass sound for very tight spaces. Its compact rectangular enclosure and slanted connector panel enable flush-mounting of the cabinet against wall surfaces, reducing required installation depth to 12 inches, including connectors.

The USW-112XP is ideal for installations requiring high performance and versatility along with an appealing, discreet aesthetic appearance. Designed to be the ideal companion to Meyer Sound’s ULTRA-X20XP, it also complements the low frequencies in other Meyer Sound loudspeakers, such as the UP-4slim and those in the UPM family.

The USW-112XP has an operating frequency range of 35–140 Hz with a linear peak SPL of 119.5 dB. The bass reflex cabinet employs a low-velocity port design based on the Meyer Sound USW-210P subwoofer for high efficiency and low port distortion.

The cabinet houses a Class D power amplifier with signal processing including correction filters for phase and frequency response, and driver protection circuitry.

The USW-112XP model with IntelligentDC technology suits applications where AC distribution is a limiting factor. The USW-112XP receives DC power and balanced audio from a Meyer Sound MPS power supply using a single composite cable and connector.

The USW-112XP requires an external Meyer Sound MPS 48 V DC power supply. Using an external power supply eliminates the need for wiring conduits while still preserving the advantages of a self-powered loudspeaker system. The unit's onboard amplifier and signal-processing circuits are designed to store DC power and tolerate voltage drops, thereby accommodating long, light-gauge cable runs.

The RMS™ remote monitoring system is available through the MPS-488HPp power supply and provides comprehensive, real-time information about loudspeaker parameters from a Mac® or Windows®-based computer running Compass® control software via the RMServer interface.

Meyer Sound constructs the USW-112XP cabinet from premium birch plywood coated with a durable black-textured finish and includes a powder-coated, round-perforated steel grille to protect the drivers. Weather protection and custom color finishes for specific cosmetic requirements are available options.

With its versatile shape, the USW-112XP can be placed on the ground in a horizontal or vertical position to accommodate installation requirements and includes an integral 35 mm pole mount receptacle with M20 threads for added stability.
