dispersion in the 2 kHz octave band (-6 dB) • Wide frequency response of 86Hz to 8kHz (-3 dB) is perfect for speech and general messaging playback APPLICATIONS The perfect choice for education, military/government, and large scale corporate applications, Berbee’s InformaCast IP Broadcasting Solution revolutionizes communication, clock/bell and message playback functionality. It provides the capability to simultaneously send a multicast audio stream and text messages to any combination of Cisco IP phones, Atlas Sound IP speakers, and PCs. With the push of a single button on the phone or a single click from a PC, a user can send a live, recorded, or scheduled broadcast to one or more paging groups. With InformaCast compliant loudspeaker products from Atlas Sound, system designers and integrators will have the ability to deploy extremely large scale and complex paging systems over new or existing Cisco networks with the convenience of centralized administration by IT personnel. Extreme cost savings can also be realized from the elimination of separate “stand alone” paging systems when InformaCast is utilized in education applications in conjunction with the model I128SYS speaker system. GENERAL DESCRIPTION Model I128SYS from Atlas Sound consists of a factory assembled loudspeaker/baffle 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 . loudspeaker with 9VDC minimum power provided by Cisco 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 industry standard C10A loudspeaker used in the I128SYS is a dual cone 8” (205 mm) loudspeaker with a 10 oz (260 g) ceramic magnet. It includes a curvelinear paper cone for lower harmonic distortion. The loudspeaker is also equipped with a full 1" (25 mm) 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. The baffle is finished in neutral white electrostatic powder coat and is packaged with all necessary mounting screws.
