Model I8SC IP speaker from Atlas Sound consists of a factory assembled loudspeaker/ baffle/ digital clock with PCB amp/ control board securely mounted to the rear of the baffle via concealed weld studs.The amp/ control board is capable of producing 9 Watts RMS into the 8 Ohm loudspeaker with 9VDC minimum power provided by IEEE 802.3 AF compliant POE switches, (local 12-18VDC PSU's may also be used instead of POE switches). Interconnect is via a board mounted female RJ-45 connector.The clock display is a brilliant red 5 element device capable of creating 2.75" (70mm) high x 1.25" (32mm) wide clock numbers. The industry standard C10A loudspeaker used in the I8SC is a dual cone 8" (205mm) loudspeaker with a 10oz (260g) ceramic magnet. It includes a curve-linear paper cone for lower harmonic distortion. The loudspeaker is also equipped with a full 1" (25mm) diameter copper voice coil with aluminum former for better heat dissipation.The 18 gauge construction of the metal baffle provides security and durability in commercial applications. A perforated 22 gauge metal screen is provided over the loudspeaker to maximize performance by allowing the optimum percentage of open area forward of the loudspeaker. The baffle is finished in neutral white electrostatic powder coat and is packaged with all necessary mounting screws.
