Introduction

Congratulations and thank you for your purchase of this professional, powered loudspeaker product. To get the most from your investment, we recommend you review all the information provided in this User Manual.

The Modular Design (or “MD”) self-powered loudspeakers provide excellent sound quality, quality construction, energy-efficient and clean power amplification on-board, and a multitude of models with common cabinet design making installation easier. Its self-contained installation solution, optimized equalization and crossover, rotatable high frequency horn, 15 attachment points, and minimal weight increase over non-pow- ered versions enable the powered MD series to solve more application challenges than competing designs. Available in black or white, they are the perfect solution for house-of-worship, performing arts center, and arena applications that demand flexible and excellent-sounding system solutions.

All models are self-powered, using highly efficient class-D amplifiers and high-frequency switch-mode power supplies. AC line connection is fast and easy; a locking, quick-disconnect Neutrik PowerCon ensures reliable AC mains connection while providing an easy-to-remove power cord for cabinet mobility. Audio is input to the self-powered loudspeaker via an XLR connector with an additional XLR output for daisy-chaining. Handles are provided on black-colored enclosures, while white-colored enclosures are not equipped with handles. Features vary by model, so please refer to sales brochures for specific model information.

Installation

There are fifteen (15) load-rated pick points on the MD enclosure; four each on the top and on the bottom, two each on the sides, and three on the rear of the enclosure. As shipped from the factory, each pick point has a strength rated flat head bolt installed. These bolts are load bearing components of the enclosure. Do not remove these bolts except to replace a bolt with a forged-shoulder eye bolt. If a flat head screw is lost, con- tact QSC’s Technical Services department for a replacement.

Ensure all pick-point fasteners are installed and correctly tightened in order to maintain enclosure’s rated strength. Additionally, air leaks resulting from missing hardware will degrade the loudspeaker’s performance.

Use only 3/8-inch, 16 threads per inch forged shoulder eye bolts, QSC part number SR-000096-00. Contact QSC Technical Services depart- ment for complete information.

Before placing, installing, rigging, or suspending any speaker product, inspect all hardware, suspension, cabinets, transducers, brack- ets and associated equipment for damage. Any missing, corroded, deformed, or non-load rated component could significantly reduce the strength of the installation, placement or array. Any such condition severely reduces the safety of the installation and should be immedi- ately corrected. Use only hardware which is rated for the loading conditions of the installation and any possible short-term, unexpected overloading. Never exceed the rating of the hardware or equipment.

Consult a licensed, Professional Engineer regarding physical equipment installation. Ensure that all local, state and national regulations regarding the safety and operation of flying equipment are understood and adhered to.
