EAW LA460 User Manual

FEATURES

• Compact Virtual Array Technology™ three-way system

• Horn-loaded MF/HF (60° x 45° coverage pattern)

• 15-in LF/8-in MF/1.4-in exit HF

• Switchable powering: full range passive or bi-amp (passive LF/MF)

• For portable use or permanent installation

DESCRIPTION

A 3-way full range system in a trapezoidal enclosure. Includes a 15-in woofer, a horn-loaded 8-in midrange cone and a 1.4-in exit/1.75-in voice coil compression driver on a

60° x 45° constant directivity horn. The powering mode is

switchable: passive (3-way crossover) or bi-amplified (passive low/mid crossover).

APPLICATIONS

The LA460 applies Virtual Array Technology to small venue performance in both portable applications and permanent installations. With EAW’s mathematically correct midrange flare, pattern control is maximized throughout the vocal region providing exceptional speech intelligibility in a compact enclosure. Six year warranty.

Applications include:

Band PA Dance Clubs Portable A/V

DIMENSIONAL DRAWING A & E SPECIFICATIONS

DIMENSIONAL DRAWINGS

The three-way full range loudspeaker systems shall incorporate a 15-in LF transducer, an 8-in MF transducer and a 1.4in exit/1.75-in voice coil compression driver HF transducer.

The LF driver shall be mounted in a vented enclosure tuned for optimum low frequency response. The MF driver shall be loaded into a midrange horn constructed of 1/8-in birch plywood reinforced with high density polyurethane foam. The MF horn shall incorporate a phase/displacement plug. The HF driver shall be loaded on a constant directivity horn with

a nominal coverage pattern of 60° (h) x 45° (v).

Powering mode shall be switchable between full range passive and bi-amplified operation. In full range passive mode, an internal passive filter network shall provide fourth order acoustical crossover and system equalization between the low, mid and high frequency sections. In bi-amplified mode, an internal passive filter network shall provide fourth order acoustical crossover and system equalization between the low and mid frequency sections.

System frequency response shall vary no more than ±3 dB

from 62 Hz to 20 kHz measured on axis. The full range system shall produce a Sound Pressure Level (SPL) of 97 dB SPL on axis at 1 meter with a power input of 1 Watt and shall be capable of producing a peak output of 130 dB SPL on axis at 1 meter. The low/mid section in bi-amplified mode shall produce a Sound Pressure Level (SPL) of 97 dB SPL on axis at 1 meter with a power input of 1 Watt, and shall be capable of producing a peak output of 130 dB SPL on axis at 1 meter. The high frequency section in biamplified mode shall produce a Sound Pressure Level (SPL) of 108 dB SPL on axis at 1 meter with a power input of 1 Watt, and shall be capable of producing a peak output of 136 dB SPL on axis at 1 meter. The full range system shall handle 500 Watts of amplifier power (AES Standard) and shall have a nominal impedance of 8 Ohms. The low/mid section in biamplified mode shall handle 500 Watts of amplifier power (AES Standard) and shall have a nominal impedance of 8 Ohms. The high frequency section in biamplified mode shall handle 150 Watts of amplifier power and shall have a nominal impedance of 8 Ohms.

The loudspeaker enclosure shall be trapezoidal in shape. It shall be constructed of 1/2-in thickness void-free cross-grainlaminated Baltic birch plywood and shall employ extensive internal bracing. It shall be finished in black catalyzed polyurethane. Input connectors shall be 2x Neutrik NL4 Speakon. A total of 3x 3-position flytracks with integral 3/8"-16 threaded mounting points (2 top and 1 back) shall be provided. The front of the loudspeaker shall be covered with an arced, vinyl-coated, perforated steel grille.

The 3-way full range loudspeaker shall be the EAW model LA460.
