Designed using precision performance high speed and low noise electronic components


Featuring a new high quality DSP engine with clear and natural sound. The DSP is designed around the latest ESS chip sets and hardware. Audio signals can be fed into the amplifiers either in the analogue domain by balanced XLR or digitally over ethernet by RJ45 connection.

The fully featured 96kHz DSP ensures the best sound. Updated FATWARE software continues to give quick, responsive user interaction and signals can be routed quickly and efficiently. FFA HD amplifiers are designed using precison performance high speed and low noise electronic components.

The high efficiency Class D PWM amplifier circuits are fully discreet and our high current SMPS will sustain low frequency energy continuously.


Offering 3 power points with equal DSP specifications the amplifiers can be used for a variety of roles. Any sound reinforcement for Café, Restaurants, Bars, Hotels, Cinemas AV, Nightclubs, tour and temporary sound, outdoor music festivals. The clear sound quality is ideal for audio that needs to heard or enjoyed.
