Atlas Sound I128SYS specifications Architect And Engineer Specifications

ARCHITECT AND ENGINEER SPECIFICATIONS

Unit shall be Atlas Sound Model I128SYS. The loudspeaker system shall include factory assembled loudspeaker, IP addressable PCB amplifier/control/metal baffle and enclosures. The loudspeaker shall have a 10 oz (260 g) ceramic magnet and a seamless cone. Frequency response range shall be 86 Hz to 8 kHz (-3 dB). Sensitivity shall be

94 dB average. Voice coil former shall be black anodized aluminum to help dissipate heat, have an impedance of 8 Ω and a diameter of

1" (25 mm). The IP addressable PCB amplifier/control shall be mounted to the rear of the loudspeaker baffle via concealed weld

studs. The amplifier / control PCB shall be capable of producing 9 Watts RMS with a minimum of 9VDC power provided either locally or via Cisco IEEE 802.3AF compliant POE switches. Interconnect shall be via female RJ-45 connector mounted to the PCB. All control functionality of the PCB amplifier shall be determined via software. The metal loudspeaker baffle overall dimensions shall be 11.94" (303 mm) wide by 23.67" (601 mm) tall. Baffle construction shall be of 18-gauge cold rolled steel. Finish shall be Atlas Sound neutral white electrostatic powder coat. Enclosure shall be included.
