The AF 500H provides a high output range and various connections – from a microphone input to a relay output. That’s why the amplifier is universally suitable for any size of application – even for complex public address and Intercom solutions. In order to avoid cabling costs and be more flexible, the AF 500H is specifically optimised for installation either in a 19” rack or on-site.

Thanks to its high flexibility, the AF 500H 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.
