RCF ZM 2124 Amplifier

The RCF ZM 2124 is the master unit at the heart of the ZM 2000 commercial audio system, combining a 6-zone preamplifier with a built-in 240-watt amplifier in one chassis. It runs on a dual-bus architecture: the first bus handles selective and all-call paging, while the second distributes background music or other program material, so speech announcements and music can move independently through the same six zones.

The unit accepts a dedicated paging input for up to six BM 2006 microphones, an emergency audio input, and an auxiliary external amplifier input, with selectable input priority and a built-in chime generator to structure announcements. It links up to eight ZE 2200 zone expansions to grow the system, supports a dedicated wall-mount remote control, and accepts 24V DC on a secondary supply for backup power.
