Clear-Com FSII BASE II
The FSII-BASE-II is the heart of a FreeSpeak II wireless intercom, a 1RU base station that runs a full-duplex digital wireless crew. It supports up to 25 beltpacks and, uniquely, mixes 1.9GHz and 2.4GHz FSII beltpacks and active transceiver antennas on the same base, so you can pick the band that fits the RF environment at each venue. Base-to-beltpack audio runs 100 Hz to 7.1 kHz for clear, intelligible comms across the coverage area.
It connects to the wired world through four 2-wire analog partyline ports, four 4-wire audio ports, a program-audio input, and a dedicated stage-announce output, tying the wireless crew into an existing intercom. Two transceiver antennas connect natively, expandable to ten through FSII-SPL splitters for larger coverage. Channels and functions are assigned from the front-panel menu or the browser-based Core Configuration Manager.
