AF 20D
Digital 20 watt amplifier with polycarbonate housing for connection to an Intercom Server. Output power 1 x 20 watt at 4 ohm loudspeaker or 2 x 10 watt at 8 ohm loudspeakers.
Their compact design makes the 20 watt amplifiers ideal for a decentralised, cable saving installation next to PA loudspeakers and Intercom terminals.
The range of application environments is suitably flexible as well, serving the public address needs in areas 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.
