Overview:
F Series amplifiers are made for Funktion One by English amplifier designers and manufacturers Full Fat Audio (FFA). The three amplifiers in the range are the excellent high power F100-2 dual power supply amplifier (suited to driving 4 x 8 Ohm 21″ drivers per channel at 2 Ohms) and two four-channel amplifiers (the F40Q and F60Q). The 4 channel amplifiers are very useful for a wide variety of applications. All three amplifiers utilise rugged switch modulation power supplies (SMPS) with Class D Pulse Width Modulation amplifier stages.
Optional pre-set internal crossover cards can be ordered for specific multi-way applications as required. The card preset specification includes bandpass crossover, relative gain, limiter and time alignment of low frequencies for all channels as well as a mono sum bass option. (It is not currently possible to time delay mid-high frequencies).
Features:
- Power efficient and cool running
- Lightweight
- Analogue filter option card with limiter threshold delay (4.ch. only) (ideal for stage monitor systems)
- Rugged tour class Aluminium construction
- FFA class D technology
- Side chain TCA clip limiter
- Signal link through
- Hand built and designed in England
- New versions now available with built-in DSP
