EAW CLA37 Manuel utilisateur

Part No. 0012698 Rev. F 05/07

DESCRIPTION

The CLA37 is an economical solution for exceptional delity in

speech reinforcement and background music applications. It

is especially suited for small to mid-sized spaces with excessive

reverberation or problematic sound reections. The drivers and

system voicing are designed to maximize vocal range clarity

and speech intelligibility without compromising the broadband

frequency response required for pleasing music reproduction.

The CLA37 uses sophisticated, frequency shading to progressively

shorten its acoustic length with increasing frequency. The result is

a well-behaved nominal vertical beamwidth of 30° to below 1 kHz

that eliminates troublesome lobing. In the horizontal plane, the

drivers act as direct radiators. A waveguide loads the three center

drivers to maintain the nominal 120° beamwidth at

high frequencies.

The included bracket allows setting the enclosure’s vertical angle

for both wall-mounting and suspension. An optional input panel

is tted with an integral transformer for 70 V or 100 V distributed

applications. The cross-ply laminated birch enclosure is available

in either black or white nish and the powder coated steel grille is

foam-backed to hide the drivers from view. The entire loudspeaker

is fully tested at the time of manufacture and is warranted to be free

from defects in materials and workmanship for a period of ve years

from the date of purchase.
