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.
