ACOUS TIC ERSHIP RTN ORMANCE PA PERF AL TECHNICAL SPECIFICATIONS AS490 DESCRIPTION A 2-way mid/high system (passive mid/high crossover) in a trapezoidal enclosure. Includes a horn-loaded 10-in MF cone and a 1.4-in exit/44mm voice coil HF compression driver on a 90 x 45 constant directivity horn. APPLICATION The AS490 provides the mid/high performance capabilities of the 90° (h) AS Series systems in a separate mid/high module. It can be used as a stand-alone system for speechonly applications or, together with an AS415, AS422 or AS625 LF module, it provides full range performance in a flexible, modular, multi-enclosure format. Includes comprehensive 3/8"-16 mounting/suspension points. Six year warranty. Applications include: Stadiums Arenas Dance Clubs Theaters Performing Arts Centers Houses of Worship DESCRIPTIVE DATA Part Number Product Group System Configuration Powering Configuration(s) MF Subsystem & Loading HF Subsystem & Loading Recommended High-Pass Frequency (24 dB/Octave) Cabinet Type (shape) Enclosure Materials Finish Connectors Suspension Hardware Grill Options 999672 I 2-way, Mid/High Passive MF/HF Crossover 1x 10-in, Horn-Loaded 1x 1.4-in exit/44mm voice coil Compression Driver on Constant Directivity Horn 200 HZ Trapezoidal Baltic Birch Plywood Black Polyurethane 2-Terminal Barrier Strip (12) 3/8"-16 Threaded Mounting/ Suspension Points (3 each Top and Bottom, 2 on Sides and Back) Powder Coated Perforated Steel 104001 3/8”-16 Eyebolt (FC300B) NOMINAL DATA Frequency Response (1 Watt @ 1m) ±3 dB 250 Hz to 17 kHz -10 dB 115 Hz Axial Sensitivity (dB SPL, 1 Watt @ 1m) Passive MF/HF 105 Impedance (Ohms) Passive MF/HF 8 Power Handling, AES Standard (Watts) Passive MF/HF 360 Calculated Maximum Output (dB SPL @ 1m) Passive MF/HF Peak 136.6 Passive MF/HF Long term 130.6 Nominal Coverage Angle/-6 dB points (degrees) Horizontal 90 Vertical 45 Dimensions inches millimeters Height 22.50 572 Width (Front) 24.63 626 Width (Rear) 14.04 357 Depth 19.75 502 Trapezoid Angle 15 degrees per side Weights pounds kilograms Net Weight 83 37.8 Shipping Weight 97 44.1 EASTERN ACOUSTIC WORKS One Main Street, Whitinsville, MA 01588 • (508) 234 - 6158 • FAX (508) 234 - 8251 • Email [email protected] • Web http://www.eaw.com EAW products are continually improved.

The MF driver shall be loaded into a midrange horn constructed of 3mm birch plywood backed with high density polyurethane foam. The HF driver shall be loaded on a constant directivity horn with a nominal coverage pattern of 90° (h) x 45° (v). An internal passive filter network shall provide fourth order acoustical crossover and system equalization. 1.97 22.50 FRONT AS490 BOTTOM System frequency response shall vary no more than ±3 dB from 250 Hz to 17 kHz measured on axis. The system shall produce a Sound Pressure Level (SPL) of 105 dB SPL on axis at 1 meter with a power input of 1 Watt and shall be capable of producing a peak output of 136.6 dB SPL on axis at 1 meter. The system shall handle 360 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 polyurethane. Input connectors shall be 2-terminal barrier strip. Twelve (12) 3/8"-16 threaded mounting/suspension points (3 each top and bottom, 2 on each side and back) shall be provided. The front of the loudspeaker shall be covered with a powder coated perforated steel grill. The mid/high loudspeaker shall be the EAW model AS490.
