Loudspeaker Owner’s Manual

Congratulations on the purchase of your new EAW loudspeaker. You now own one of the finest professional audio products available - the result of exceptional engineering and meticulous craftsmanship. Please read these instructions to get the maximum performance from your new loudspeaker.

Section 1 Read This First

1.1 Rigging Precautions

Prior to suspending any EAW loudspeaker enclosures, it is essential that the user be familiar with the load ratings, rigging techniques, and special safety considerations appropriate for this use. Use only the mounting/rigging points on the loudspeaker enclosure intended for this purpose. The user must determine the load requirements, dynamic loading and any other contributing factors affecting the flown loudspeakers. The user must determine the proper safety factor for specific applications and the required load rating of the connection to structure. EAW strongly recommends that all rigging be done by qualified personnel in accordance with and in compliance with all federal, state and local regulations, relative to properly securing suspended loads.

NOTICE: The user assumes liability for proper design, installation and use of rigging systems.

EAW strongly recommends the following rigging system practices:

1. Documentation: Thoroughly document the rigging design with detailed drawings and parts lists.

2. Analysis: Have a licensed structural engineer, registered architect or other qualified professional review and approve the rigging design before its implementation.

3. Installation: Have a qualified professional rigger install and inspect the rigging system.

DANGER: Loudspeakers should be suspended only by persons with a knowledge of proper hardware and rigging techniques. When stacking or pole-mounting loudspeakers, be sure they are stabilized and secured from falling over or being accidentally pushed over. Failure to follow these precautions may result in damage to the equipment, personal injury or death.

Section 2 Unpacking

2.1 Shipping Damage

You should have visually inspected the outside of the shipping carton and noted any damage on the shipping bill you signed. After unpacking, if you find concealed damage to the loudspeaker, save the packing materials for the carrier’s inspection, notify the carrier immediately and file a shipping damage claim. Although EAW will help in any way possible, it is always the responsibility of

the receiving party to file any shipping damage claim. The carrier will help prepare and file this claim.

Section 3 Description

3.1 System Overview

This loudspeaker is intended for professional use. The construction, components and hardware have been designed to provide robust, reliable performance for its intended application. Please ensure that you fully understand its proper installation and operation before use.

Section 4 Operation

4.1 Amplifier Power Requirements

There is no exact answer to the question of what amplifier size you should use for a loudspeaker. The power rating in EAW’s specifications only means it has passed our standard noise test, providing a rating that can be used as a point of comparison with other loudspeakers. This rating does not necessarily correspond to the best amplifier size to use. Rather, the amplifier should be sized according to both the sound levels required and the type of audio signals that will be reproduced. If you are unsure of how to determine this, consult with a qualified professional or contact EAW’s Application Support Group (see paragraph 4.5). Preventing damage to the loudspeaker is a function of operating your audio system so that the loudspreaker is not stressed beyond its design limits. If operated improperly, such as driven into clipping, even an amplifier sized below EAW’s power rating can cause damage to your loudspeaker.

4.2 Audio Signal Connections

The input connector on the loudspeaker will be one of the following types with the pin connections as listed. Because of possible prodution changes, check the input panel labeling to verify proper connections. For barrier strips, the proper connections are marked for each terminal on the loudspeaker input label.
