The VARIO-LINE VLA-120C is a professional amplifier and control unit designed for voice announcement and paging systems. It supports up to 5 independently controllable loudspeaker zones plus an All-Call function for broadcasting to all zones simultaneously. Each zone's volume and activation can be adjusted individually—making it ideal for use in schools, public buildings, industry, or event facilities.

The system accepts all standard microphones and is optimized for VARIO-LINE paging stations such as VLM-100A, VLM-105 (digital zone control), and VLM-205 (also controls digital message module DM-10). Three combo MIC/LINE inputs with switchable phantom power, gain and priority controls, and two LINE inputs provide comprehensive connectivity.

Built-in features include an auto DC fan, full safety protections (“overload,” “overheat,” “overcurrent”), 2- or 4-tone chime, siren, TEL-paging with priority, and a media module slot for pre-recorded audio content—making the VLA-120C a versatile and reliable heart of any modern public address system.
