The DSP (Digital Sound Processing) integrates input setting filters. It also offers a 10-band parametric EQ per channel, a time alignment and refined filters on outputs, as well as many refined adjustable settings, including: bass boost, compressors, loudness, master volume, surround, and progressive phase inverter.

The channels incorporate an active crossover (high-pass, low-pass and band-pass) to perfectly configure the sound response based on the speaker drivers used, achieving the sharpest possible sound.

The FIT 9.660 amplification is class A/B over 3 channels, for the left tweeter, right tweeter and central speaker, for fine voice details, and class D over 6 channels.

With an efficiency exceeding 90%, class D offers many benefits: low heat, low power consumption, low distortion at high volumes, dynamics in the low frequencies, compact size, etc., enabling FIT 9.660 to achieve high power for its small dimensions. In particular, it builds up 3 x 20 watts RMS in class A/B and 6 x 70 watts RMS in class D under 4 Ohms. Remarkable power, fast attack-time for a highly realistic and dynamic sound.
