Fredenstein F603A-EQ 500 Series Equalizer

The Fredenstein F603A 500-Series High-Q EQ combines passive LC (Inductor/Capacitor) filters with a minimal signal path. It features shelving type filters for low and high frequencies, and band pass filters for mid frequencies, with four and six selectable frequencies respectively. Active filter ranges are indicated by LEDs, and a true "hard" bypass allows for direct sound comparisons. Each filter offers a gain range of +/- 16 dB.

Known for its silky yet detailed sound stage, the F603A boasts a high power output stage with an impedance of less than 20 Ohms and a driving capability up to +/- 200mA, ensuring optimal performance with complex loads.

Like all Fredenstein products, the F603A is designed by a German-American team and manufactured in Taiwan, reflecting precision engineering and high-quality standards.
