Description The ZM 2124 is a master unit from the ZM 2000 system series, equipped with a 240 W internal amplifier and a preamplifier managing six selectable zones. Built on a dual-bus architecture, it separates selective/all-call paging from music or other audio signals for flexible audio routing. This architecture enables independent control of paging and music distribution, with toggle buttons to enable or disable music on each zone. The system supports priority management for audio inputs, multiple paging inputs, and auxiliary external amplifier input for zones requiring additional power. It also features programmable general-purpose inputs and outputs for integration with external devices and automation systems. Designed for small to medium-sized installations, the ZM 2124 links up to eight ZE 2200 zone expansions, extending its reach to a total of up to 54 zones. It supports up to six consoles and offers various input connectors, including XLR and RCA, for microphone, line, and paging sources. With a robust metal chassis and rack-mountable 19″ 3U size, the unit is suitable for professional installations requiring reliable multi-zone audio control with emergency and paging capabilities.
