Series amplifiers are made for Funktion One by English amplifier designers and manufacturers Full Fat Audio (FFA). The four channel DSP models; Networking, four inputs and six outputs (four via amplifier channels and two via additional signal channels) and intuitive software offer great flexibility for both live and installation. The new F20Q is useful for powering distributed systems of small loudspeakers such as the F55 or F81. 
 
The F80Q's new electronic design makes it especially suited to powering the Evo 6 and 7 range with exceptional audio quality. 

All amplifiers utilise rugged switch modulation power supplies (SMPS) with Class D Pulse Width Modulation amplifier stages.
