The VARIO-LINE VLA-240C is a powerful central amplifier and control unit designed for professional public address applications. It supports up to 5 independently switchable loudspeaker zones plus a global All-Call function. Each zone's volume can be individually adjusted—making it suitable for schools, public buildings, industrial sites, or event venues.

This amplifier is especially compatible with VARIO-LINE paging stations VLM-100A, VLM-105 (remote control of speaker circuits) and VLM-205 (also controls the DM-10 digital message module). Three MIC/LINE inputs offer phantom power, gain and priority settings for flexible use. The unit features automatic fan control, comprehensive protection circuitry, and dual power options (AC + 24 V DC backup).

Additional features include a 2- or 4-tone chime, an electronic siren, and TEL-paging with priority. It also includes AMP-IN/OUT connections for cascading with external amplifiers or signal routing via 0 dB converters. A dedicated slot allows the integration of a media playback module.
