Model I8SC from Atlas Sound consists of a factory assembled loudspeaker, LED clock, baffle with PCB amplifier, and control board securely mounted to the rear of the baffle via concealed weld studs. The amplifier/control board is capable of producing 9 Watts RMS into the 8O loudspeaker with 9VDC minimum power provided by IEEE 802.3af-compliant POE switches. Local 12VDC - 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 I8SC is a dual-cone loudspeaker with a ceramic magnet. The LED clock is a dot matrix LED display. The 18-gauge construction of the metal baffle provides security and durability in commercial applications.
