For EN54-24 voice evacuation systems that also carry music, the white LRC-1100 gives 65 Hz to 14 kHz (-10 dB) from a 950 mm column of twelve 2.5″ drivers. Its built-in ASC transformer offers taps up to 120W on 70V or 100V lines, and it can also run at 8 ohms. A switchable 20° or 40° vertical pattern with 5° downward bias keeps energy on the audience, and the SwifTilt bracket comes in the box.
