Stage Accompany has introduced the new EFN-DP processing modules, an extension of the Extended Function Network (EFN) circuitry, featured in its Efficiency Series amplifiers. Dedicated to SA loudspeakers, each module features three speaker-dedicated functions, operating simultaneously - clip/excursion protection, dedicated filtering and power optimizing. The clip/excursion parameters are dedicated to the exact specifications of the driver and cabinet, and the excursion protection is a frequency-dependent, zero-attack limiter. The filtering is adjusted to the system set-up, i.e. the filtering for a top/sub system can be a combination of Bessel and Butterworth filter characters, or can have phase correction/alignment.The third function of the EFN-DP module is power optimizing. Due to the different RMS/peak power values of a speaker and an amplifier, either the actual output capacity of a speaker is never used 100%, or the speaker is exposed to over powering. The power optimizing of the EFN-DP module matches power output of the amplifier with the RMS/peak power handling of the speaker. The circuitry is Opto-coupler regulated for less noise and distortion. Combining the EFN-DP processing with SA’s Dynamic Damping Control circuitry, Stage Accompany say they have achieved the ultimate synergy between speaker and amplifier.
