Thanks to its compact design, the AF 20H is ideal for a decentralised, cable saving installation next to PA loudspeakers and Intercom/SIP stations. The AF 20H cannot just be used as an amplifier, it also works as an IP interface between classic PA systems and a modern networked Intercom system. Thanks to its high flexibility, the AF 20H is applicable in the most diverse areas where a reliable and powerful public address is needed. Thereby, this amplifier covers all requirements from public service facilities, critical infrastructure and smart city applications, office and school buildings up to the requirements of challenging and high-noise industrial environments
