FFA 4004

Full power delivery all channels driven simultaneously loaded 4 ohms


Very useful and versatile multimode amplifiers, suited for large scale touring point source or line array systems. Equally suited in less demanding bass applications. Very installation friendly and ideal for bi amp stage monitoring systems or multi point theatre installations. Proprietary high efficiency FFA Class D output stage coupled with high current switch mode supply enables high power delivery even in the harshest environmental conditions.
