Model ZC1-CK from AtlasIED consists of a factory assembled PCB control board housed in a rugged and compact 1RU chassis. The unit provides the same addressable end point functionality as an IP speaker or IP phone with the convenience of line level audio output. This line level output is perfect for use with Atlas AA, PA or CP series amplifiers to power large zones of traditional 25V, 70.7V or 100V Atlas speaker or paging horn assemblies. The unit receives 12VDC power provided by IEEE 802.3 AF compliant POE switches (local IPS-PSU 12 VDC-18 VDC PSUs may also be used instead of POE switches). Network interconnection is via a board mounted female RJ-45 connector on the front panel. , Output is balanced line level via a 3 pole terminal block on the rear panel.
