The series AF 50 provides a particularly high output range and various loudspeaker outputs. These amplifiers are universally suitable for any size of application up to complex public address and Intercom solutions. They are specifically optimised for installation either in a 19” rack or on site. This helps to save on cabling and any costs incurred.

The range of application environments is suitably flexible as well: serving the public address needs from public service facilities (e.g. railway stations) to auditoriums or waiting rooms and covering the Intercom requirements of noisy industrial facilities, garages, tunnels or office buildings.
