Model I8SCM IP loudspeaker from AtlasIED consists of a factory assembled loud loudspeaker/ baffle/ digital clock and microphone 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 802.3AF compliant POE switches. (local 12-18VDC PSUs may also be used instead of POE switches). Interconnection is via a board mounted female RJ-45 connector. The clock display is a brilliant 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 curvelinear 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. A omni directional subminiature (1/ 4" / 6mm), electret condenser microphone is mounted behind the stainless steel perf material adjacent the loudspeaker to allow 2-way communication and/ or monitoring from the loudspeaker location to any PC or IP phone in the system.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.
