Modules Efficiently Control Audio Fidelity

Designed for use with all SA audio systems, the EFN-DP processing modules are said to ensure maximum output with optimum sound fidelity. Each module features three speaker-dedicated functions: clip and excursion protection, dedicated filtering, and power optimizing.
The excursion protection is a frequency-dependent, zero-attack limiter said to be accurate to the millimeter. Filtering can be a combination of Bessel and Butterworth characteristics or can have phase correction and alignment.
The power optimization module matches the power output of the amplifier with the rms and peak power handling capabilities of the speaker. Its circuitry is opto-coupler regulated for less noise and distortion.
