DESCRIPTION A dedicated PPST long throw high frequency system in a trapezoidal enclosure. Includes 5x 2-in exit compression drivers on SimplePhase™ horns. APPLICATIONS 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 frequency 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: Stadiums Concert Tours DESCRIPTIVE DATA Part Number HF Subsystem & Loading System Configuration Powering Configuration System Crossover Controls (switches, knobs) Recommended High-Pass Frequency (24 dB/Octave) Cabinet Type (shape) Enclosure Materials Finish Connectors Suspension Hardware Grill

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 integrated 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 capable 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 15mm 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 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 loudspeaker shall be covered with a vinyl coated perforated steel grill backed with open cell foam to protect against dust. The long throw high frequency module shall be the EAW model KF910.
