DESCRIPTION

PERFORMANCE

APPLICATION

A dedicated PPST long throw high frequency system in a

trapezoidal enclosure. Includes 5x 2-in exit compression driv-

ers on SimplePhase™ horns.

The KF910 PPST long throw HF module is engineered for use

in KF900 Series arrays. It provides HF coverage from 0° to 15°

below the array. It is engineered to provide extended high fre-

quency response at distances in excess of 600 ft. KF900 Series

modules can only be used in arrays and must be integrated

with complex PPST processing. Six year warranty.

Applications include:

EXP 9/4/97 SHB

The long throw high frequency module shall incorporate 5x

horn-loaded 2-in exit compression driver HF transducers. The

module shall have a nominal horizontal coverage pattern of

30°. The module’s vertical beam profile shall be adjustable via

complex digital signal processing. The module shall be inte-

grated with complementary frequency-specific modules into a

single acoustical unit via complex digital signal processing.

Module frequency response shall vary no more than ±3 dB

from 500 Hz to 14 kHz measured on axis. The module shall

produce a Sound Pressure Level (SPL) of 117 dB SPL on axis

at 1 meter with a power input of 1 Watt, and shall be capa-

ble of producing a peak output of 153 dB SPL on axis at 1

meter. Each driver shall handle 200 Watts of amplifier power

(AES Standard) 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-grain-

laminated Baltic birch plywood and shall employ extensive

internal bracing. It shall be finished in black catalyzed

polyurethane. Input connectors shall be one each male and

female AP6 plus two Neutrik NL4 Speakon. The enclosure shall

include sixteen 3/8”-16 threaded mounting/suspension

points (4 each top, bottom and sides). The front of the loud-

speaker shall be covered with a vinyl coated perforated steel

grille backed with open cell foam to protect against dust.

The long throw high frequency module shall be the EAW model

KF910.
